Milwaukee County Executive David Crowley and County Board President Marcelia Nicholson-Bovell signed legislation Wednesday afternoon reaffirming the county’s commitment to adhering to the goals of the 2016 Paris Climate agreement. 

“In Milwaukee County, we know that the climate crisis is a real, pressing threat to our environment, our economy, our health, and our quality of life,” Crowley said at the gathering beside other officials at the Urban Ecology Center of Washington Park. 

The international agreement called on nations to adopt policies to keep average global temperatures from increasing more than 2 degrees Celsius above pre-industrial levels. The United States joined nearly 200 global nations and states in signing onto the agreement under President Barack Obama. President Donald Trump pulled out of the agreement after he was sworn into office in 2017 and, after President Joe Biden rejoined the agreement, again in 2025.  Trump has called the agreement “unfair,” “one-sided,” and a “rip-off.” Since the Trump administration exited the agreement, state and local governments across the country have signaled their aims to stick with the agreement’s aims. 

Milwaukee County first signed onto the Paris Climate Accords in 2017. The county’s goal is to reach net-zero operational emissions by 2050. The event Wednesday was held on the first day of Earth Month.

Crowley praised Milwaukee’s efforts towards reducing carbon emissions and climate resiliency despite being in a time “when federal climate leadership is stepping back.” He said at the event that the county has reduced its emissions by nearly 50% since 2005. 

Nicholson-Bovell echoed the sentiment.

“Milwaukee County continues leading the way in the march toward a more environmentally sustainable community,” she said. “Our legislation recommits Milwaukee County to the Paris Agreement and Greenhouse Gas Endangerment Finding, because our children’s future depends on how we combat the climate crisis and build the equitable future we all deserve.” 

Crowley and Nicholson-Bovell were joined by Milwaukee County Supervisors Felesia Martin, Anne O’Connor and Sky Capriolo.

The Urban Ecology Center itself is an example of the steps Milwaukee County has taken towards reaching net-zero. The Washington Park center was recently renovated, becoming the first all-electric non-residential building in Milwaukee County, the center’s executive director, Jen Hense, explained. 

Now the building creates zero emissions and, with the planned installation of 100 new solar panels next week, is set to reduce its energy consumption by about one-third.

When the building was renovated, about 60% of its original structure was re-used. Some of the wood used in the renovations was also reclaimed from trees felled by Milwaukee County to combat the emerald ash borer insect. Bird-safe glass had also been installed, so far decreasing the number of collisions the building is responsible for. Surrounding the ecology center are ponds where people often fish, and the center works to re-introduce native plants to assist local ecosystems.

Hense stressed the importance of the Urban Ecology Center’s work. There are over 35,000 young people who attend outdoor and science programs at the county’s three Urban Ecology Centers, and more than 600,000 people visit the green spaces the center stewards in Riverside Park, Washington Park, and Menomonee Valley. 

“We know that these natural spaces, and hundreds more across the county — that are loved and cared for by amazing individuals and incredible environmental organizations — are important to our community, and are essential to protect for generations to come,” said Hense. “We know that combatting the global climate crisis can start right here in the county, and that this work is truly an act of environmental justice.” 

Nicholson-Bovell recalled growing up in a Milwaukee neighborhood where the nearest park didn’t have grass. She said that she was born premature with under-developed lungs, a condition worsened by the air pollution in her community. Studies have shown that increasing the number of urban trees would help improve polluted air conditions. 

“The environment that I grew up in had been ripped apart by the building of a freeway,” said Nicholson-Bovell. “And it was little kids like me who struggled to breathe in our communities. We didn’t have access to clean air, we didn’t have access to green space. And when I became a Milwaukee County supervisor, I promised that no child that I could help support would ever have to experience that again.”

Crowley said visiting the county’s parks reminds him “of just how lucky we are to have accessible access to beautiful green spaces like the one that we are in today.” He stressed that having this “in our backyard” should never be “taken for granted” while highlighting the success the county has already achieved at reducing its climate impact. “And it is because, and through, our office of sustainability that we remain focused on building green infrastructure, creating local sustainability jobs, and making sure that every single neighborhood is part of our climate solution,” said Crowley. 

Crowley said that partnership and collaboration with higher levels of government will be needed to fully accomplish the county’s climate goals. Yet that assistance is unlikely to come from the current federal government. Trump has repeatedly called climate change a hoax. Under Trump, the Environmental Protection Agency also repealed the 2009 endangerment finding that greenhouse gases threaten public health. During both Trump Administrations, climate data and even the words “climate change” have been purged from federal websites. Climate policies at the state level have also been blocked or frustrated by Wisconsin’s Republican-controlled legislature. 

Grant Helle, director of the Milwaukee County Office of Sustainability, said that “while federal climate leadership declines, Milwaukee County is taking action.” Helle said that local action is “not optional, but essential.” Helle noted that the new Marcia P. Coggs Health and Human Services Center will have on-site solar which will off-set over 11% of that facility’s energy use. The county is also re-thinking how building design could impact climate change, an issue which Helle said residents are concerned about. 

A stream of extreme weather events in recent months and years have likely fueled those concerns. Just weeks ago, people in parts of Wisconsin endured a historic blizzard, receiving so much snow that plow services needed to be shut down. Some Milwaukee communities still haven’t fully recovered from record-breaking amounts of rain and flooding that swept through the city in August. The Trump Administration has denied multiple requests for assistance and flood relief made by Wisconsin communities. 

Extreme heat gripped areas of the state in 2023, coinciding with increased wildfire activity within the state, while smoke from fires in Canada worsened air quality. Severe storms also hit Milwaukee and other Wisconsin communities in 2022 and 2021. O’Connor recalled the floods of 2010, where people were “literally canoeing down the street where I live in my district.” 

Crowley said that the August floods should be an indication that the midwest is not safe from climate change. 

“That tells us how do we build infrastructure that is resilient, and how do we think long term making sure that this planet is continuously livable for our young people and for many generations moving forward,” he said. 

Nicholson-Bovell said that the floods were devastating, but that climate change is a national issue. “My husband I met in St. Louis,” she said. “They had a historic tornado rip through the inner-city of St. Louis and they’re still scrambling to try and find housing for individuals.” 

Helle said that increased flooding, harsher heatwaves, and worse air quality are climate hazards Milwaukeeans are already experiencing. “It’s really unfortunate,” said Helle. “But what it does is go to show that we need to continue to make efforts here in Milwaukee County right now where we can to lower the impact on those residents that we ultimately serve.”

Communities are recovering after a major weekend blizzard, dropping record-breaking amounts of snow in some parts of Wisconsin. From the Northwoods to Milwaukee, snowfall shut down roads, caused power outages and challenged plow trucks and public services.

The National Weather Service, calling the snowstorm “historic,” said that in central Wisconsin, snow fell at a rate of 4 inches per hour. “Near-blizzard conditions developed Sunday afternoon, fueled by northeast winds gusting between 35 and 50 mph,” the weather service stated in an update. Windspeeds reached 59 miles per hour  at the Green Bay Airport, and 60 miles per hour in De Pere. “This combination of heavy falling snow and high winds created whiteout conditions and massive drifting,” the National Weather Service stated.

Historic amounts of snow reached approximately 30 inches in communities from Wausau to Marinette and Door County. In Green Bay, where 26.1 inches of snow fell as of Monday, the storm was the area’s largest in 136 years. By Sunday Green Bay had seen 17.1 inches accumulate, making it the city’s third-snowiest day and its heaviest day of snowfall since 1889. Over 11,000 people were reported to have lost power as well.

A “No Travel Advised” notice was posted on the Department of Transportation’s webpage as the storm loomed. “The heavy snow load and high winds caused widespread power outages, most notably in Door and Marinette Counties, and building collapses were reported in Sturgeon Bay and Kewaunee County,” the National Weather Services noted. “Many schools and businesses remained closed through Monday.” The snow was so overwhelming that snow plow operations halted in Marinette County, forcing the sheriff’s office to warn that emergency responses might also slow. That was an acute concern for people stranded in cars along the roadways.

Milwaukee Journal Sentinel reported that Sturgeon Bay in Dane County saw 33 inches of snow blanketing roads and neighborhoods over three days. The city of Madison recorded 5.6 inches on Monday. The state capital’s previous record was set in 2006 when 3.5 inches of snow fell. In western Wisconsin, the town of Montana received 26.5 inches of snow, more than any other area in the region. The city of Mondovi also may have broken a record with 16.5 inches the city’s unofficial record was 16 inches, according to the National Oceanic and Atmospheric Administration. 

Over the three-day snowfall event, Madison was covered in nearly eight inches. Some residents reported they were unable to open their front doors. 

Fallen trees and other damage was also reported as far south as Racine.

Waukesha County also struggled with the storm, after strong winds uprooted trees as early as Friday. The winds heralded an all-day rain storm which then turned into a blizzard. The shifting weather patterns meant that the county had to adapt rapidly. About seven inches of snow fell in Waukesha from Sunday to Monday. Crews with the Waukesha County Department of Public Works pulled 16-hour shifts. 

“In severe weather government services matter most,” Waukesha County Executive Paul Farrow said in a statement. “Waukesha County’s teams were out early, stayed out late, and worked around the clock so residents could reach essential services safely. Thank you to our crews and to the public for slowing down and giving plows the space they needed to do their jobs.” 

From 2 a.m. to 9 p.m. Monday, Waukesha County’s 911 communications center received 47 calls for disabled vehicles, 25 for vehicles in ditches, nine reports of property damage, and three for traffic hazards. In many areas people struggled to dig their cars out, with Wausau residents reporting having literally not seen their cars for days until they were uncovered from the snow. Although temperatures were below freezing on Tuesday, the weather is expected to warm as the week continues. By the weekend, temperatures are expected to reach 70 degrees before tapering off again.

Researchers have long warned that extreme weather events would become more common due to climate change. Some of the communities recovering from the blizzard have yet to fully recover from record-breaking floods that occurred in August. In January 2025, extreme arctic cold enveloped the region, challenging communities with large numbers of people living unhoused on the street. This most recent snowstorm came as other parts of the United States dealt with rashes of tornadoes, heatwaves, and flooding.

The federal administration’s decision to rescind the Environmental Protection Agency’s Endangerment Finding may sound technical. In reality, it targets the legal foundation that has allowed the United States to regulate climate pollution for more than a decade. For Wisconsin, the move introduces new uncertainty just as communities, farmers and businesses invest in cleaner energy, efficiency and more resilient infrastructure.

The 2009 Endangerment Finding concluded that greenhouse gases threaten public health and welfare. Courts have upheld that determination repeatedly. Eliminating or weakening it does not change the science behind climate change, but it could reshape how power plants, vehicles and industrial facilities are regulated. That shift carries consequences for states already dealing with smoky summers, heavier rainfall and rising infrastructure costs.

Wisconsin’s clean energy economy has expanded steadily, often without much attention. Renewable projects now generate enough electricity to power about 560,000 homes. Roughly 75,000 residents work in clean energy fields, and more than 350 Wisconsin companies supply technologies or services that reduce energy use or emissions. Together, these efforts reflect a broader reality: climate progress here tends to be practical and locally driven because it lowers costs and strengthens communities.

Examples are visible across the state. School districts and municipal buildings are cutting operating expenses through efficiency upgrades supported by Focus on Energy programs. Tribal and low-income households are receiving targeted weatherization investments that improve comfort and reduce utility bills. Builders and manufacturers are adopting higher performance standards to reduce long-term risk.

Federal rollbacks do not automatically halt these efforts, but they complicate financing and planning. Investors and local governments rely on predictable rules. When national standards shift, projects that once appeared viable can stall.

Some of the clearest examples are unfolding in rural Wisconsin. The SolarShare Wisconsin Cooperative is expanding community-owned solar projects that keep energy dollars circulating locally while pairing installations with pollinator habitat or sheep grazing. Hidden Springs Creamery installed a 50-kilowatt solar system to power its creamery and farm operations while continuing to produce artisanal cheeses. These projects reflect a simple idea gaining traction across the state: build it here, power it here, prosper here.

Wisconsin’s dairy sector has also become a testing ground for methane reduction strategies. Anaerobic digesters, renewable natural gas systems and advanced manure management technologies are already operating throughout the state. They reduce emissions while improving water quality and creating new revenue streams for farmers. If federal climate incentives weaken, fewer of these projects may move forward, leaving producers to absorb more risk and potentially slowing innovation that began here.

At the same time, new pressures are emerging from the rapid growth of artificial intelligence and large-scale data centers. Utilities are proposing infrastructure expansions to meet rising electricity demand, raising questions about cost allocation, water use and oversight. Small businesses, tribes, farmers and rural communities are organizing around siting decisions that affect farmland and ratepayers.

This week, the Power Wisconsin Forward campaign, supported by the Clean Economy Coalition of Wisconsin and more than 50 partner organizations, urged the Public Service Commission to ensure that data center costs do not shift onto ordinary customers. The debate highlights a broader reality. Wisconsin’s energy landscape is changing quickly even as federal climate policy moves in the opposite direction.

It would be misleading to suggest Wisconsin’s political environment has become less polarized. Recent legislative sessions show deep divisions and limited consensus on climate priorities. That context makes federal rollbacks more consequential. Without consistent national guardrails, states rely more heavily on local initiatives and market forces, which can advance progress but unevenly.

Legal challenges to the EPA decision are likely, but outcomes remain uncertain. In the meantime, utilities, farmers and local governments must make decisions without clear signals from Washington.

The practical question facing Wisconsin is not whether federal politics will shift. It is whether the state continues investing in projects that already deliver measurable results. Efficiency upgrades lower utility bills. Community solar keeps energy spending local. Methane reduction technologies help farms manage waste while improving soil and water conditions.

In a politically diverse state, climate progress rarely looks dramatic. It often appears as quieter momentum built through local partnerships and incremental gains. The federal rollback raises real risks, but it does not erase the infrastructure or collaboration already underway.

What happens next will be shaped less by national rhetoric and more by decisions made at the Public Service Commission, in county zoning meetings and on working farms across Wisconsin.

WASHINGTON — President Donald Trump and his top environmental policy officer finalized a move Thursday to undo an Environmental Protection Agency regulation that laid the foundation for federal rules governing emissions of the greenhouse gases that cause climate change.

At a White House event, Trump and EPA Administrator Lee Zeldin said they were officially rolling back the “endangerment finding” that labeled greenhouse gases a threat to public health and provided a framework for the EPA to regulate emissions. 

The 2009 finding, established under President Barack Obama, called climate change a danger to human health and therefore gave the EPA power to regulate greenhouse gases, such as carbon dioxide from cars and trucks. 

Such regulations created a challenge for automakers and other industries, which dragged down the entire economy, according to Trump, administration officials and allies in Congress. 

Democrats and their allies in environmental and climate activism, though, consider the measure a crucial tool to address climate change and protect human health.

Undoing the finding will remove the economy-wide uncertainty, Trump argued. 

“That is why, effective immediately, we are repealing the ridiculous endangerment finding and terminating all additional green emission standards imposed unnecessarily on vehicle models and engines between 2012 and 2027 and beyond,” he said Thursday. 

Affordability argument

In its initial notice last year that it would repeal the endangerment finding, the EPA said it did not have the authority to regulate vehicle emissions.

With household costs, including transportation, expected to be a major theme in the fall’s midterm campaigns to determine control of Congress, members of both parties have framed it as an economic issue.

“This will be the largest deregulatory action in American history, and it will save the American people $1.3 trillion in crushing regulations,” White House press secretary Karoline Leavitt said at Tuesday’s press briefing.

Some Democrats and climate activists argue the rollback will hurt the country’s nascent renewable energy sector, driving up the cost of home heating, electricity and other common expenses.

Senate Minority Leader Chuck Schumer, D-N.Y., and Sen. Sheldon Whitehouse, D-R.I., issued a lengthy joint statement slamming the announcement.

“The Trump EPA has fully abandoned its duty to protect the American people from greenhouse gas pollution and climate change.  This shameful abdication — an economic, moral, and political failure — will harm Americans’ health, homes, and economic well-being. It ignores scientific fact and common-sense observations to serve big political donors,” the senators said.

“This sham decision initially relied on a now thoroughly disgraced and abandoned ‘report’ by known climate deniers. Zeldin stuck to this charade anyway, undaunted by half a century of actual evidence, showing the fix was in from the beginning,” they continued.

Money and fossil fuels

The move outraged Democrats and climate activists when Zeldin first proposed it last summer. Climate activists say undoing the finding undercuts the federal government’s ability to address an issue critical to the United States and the entire world.

In a Tuesday floor speech, Schumer blasted the rollback as a giveaway to fossil fuel companies, leaders of which contributed to Trump’s 2024 campaign.

“Remember: In the spring of 2024, Donald Trump invited top oil executives to Mar-a-Lago and told them, if you raise me a billion dollars to get me elected, I will cut regulations so you can make more money,” Schumer said. “That devil’s bargain is now coming true. I never thought it would be this way in America, in this bald disgusting way that so hurts people’s health, but there it is.”

Democratic attorneys general and environmental groups are likely to sue over the rollback.

At least one lawsuit, from the Environmental Defense Fund, was promised Thursday afternoon.

“EDF will challenge this decision in court, where evidence matters, and keep working with everyone who wants to build a better, safer and more prosperous future,” Fred Krupp, EDF president, said in a statement Thursday. 

Washington state Attorney General Nick Brown, a Democrat, said last year he would “consider all options if EPA continues down this cynical path.”

A focus on addressing climate change, including by producing wind and solar energy, has not helped Americans keep their electricity and heat on during winter storms, U.S. Energy Secretary Chris Wright said Friday.

Ahead of another major cold snap on the East Coast, Wright briefed reporters at the agency headquarters in Washington, D.C., on the importance of maintaining electricity and heat supply during winter storms and advocated for a national energy strategy that focuses more on grid resilience and less on reducing carbon emissions. 

His statements continued a Trump administration stress on fossil fuels like coal, oil and gas that contribute to global climate change.

Americans elected President Donald Trump to move away from a focus on climate, Wright said.

“Today, the policies that get in the way of reasonable energy development and mess up the math are things focused around climate change,” he said. “We’ve done almost nothing to change global greenhouse gas emissions — as close to nothing as you can get — from endless regulations on electricity that have just driven up prices and driven down reliability in the name of climate change.”

Electricity grids and peak demand 

Electricity grids must be designed for peak demand, such as during winter storms or summer heat waves, Wright said. Efforts to increase generation capacity with renewable sources are misguided, as the United States electricity grid produces hundreds of excess gigawatts of power during normal conditions, he said.

During President Joe Biden’s administration, Democrats enacted a law providing massive tax credits for wind and solar production. Without naming that law or specific officials, Wright said those efforts were not useful.

“When I hear politicians say, ‘We just need more electrons on the grid,’ no, we don’t,” he said. “When the sun shines or the wind blows, (it) doesn’t add anything to the capacity of our electricity grid. It just means we send subsidy checks to those generators, and we tell the other generators, turn down.”

During the winter storm that gripped much of the country last month, wind energy provided 40% less electricity than it had on the same days in 2025, Wright said. Solar provided only 2% of energy to affected areas, according to a pie chart shown at the briefing.

By contrast, coal provided 25% more power than usual and natural gas produced 47% more, he said. Nuclear energy was about the same.

Renewables strengthen grid, climate group says

The clean energy group Climate Power said in a Tuesday statement that renewable sources helped fortify energy supply during peak demand times. Solar energy produced 300% more in a 2024 Texas storm than it had in a storm three years earlier. And during last month’s cold streak, areas that relied on wind saw lower prices, according to the group.

Climate Power also said natural gas infrastructure was “prone to freezes and mechanical failure.”

“As back-to-back winter storms pummeled communities across the country in January, the facts about Donald Trump’s reckless energy policies have come into focus: fossil fuels have proved less reliable and more expensive as families struggle to keep the power on,” the statement read.

Wright favors natural gas

But while Democrats and climate activists have said the U.S. should move away from oil, coal and gas because of the climate-warming emissions they release and toward renewables, Wright suggested natural gas should be emphasized instead to substitute for oil, which is more expensive and produces more air pollution.

The proposed Constitution Pipeline, which would carry natural gas from New York state to Pennsylvania, should have been approved years ago, Wright said, but was held up by a “bad political decision.”

Planners abandoned the controversial project in 2020 in the face of regulatory difficulties in New York, but revived it last year. Its federal reviews are pending.

Wright said producing more energy would also be needed for another Trump administration priority: leading in artificial intelligence development. The industry needs massive energy sources to run the data centers AI relies on.

For decades, corn has reigned over American agriculture. It sprawls across 90 million acres — about the size of Montana — and goes into everything from livestock feed and processed foods to the ethanol blended into most of the nation’s gasoline. 

But a growing body of research reveals that America’s obsession with corn has a steep price: The fertilizer used to grow it is warming the planet and contaminating water.

Corn is essential to the rural economy and to the world’s food supply, and researchers say the problem isn’t the corn itself. It’s how we grow it. 

Corn farmers rely on heavy fertilizer use to sustain today’s high yields. And when that nitrogen breaks down in the soil, it releases nitrous oxide, a greenhouse gas nearly 300 times more potent than carbon dioxide. Producing nitrogen fertilizer also emits large amounts of carbon dioxide, adding to its climate footprint.

Agriculture accounts for more than 10% of U.S. greenhouse gas emissions, and corn uses more than two-thirds of all nitrogen fertilizer nationwide — making it the leading driver of agricultural nitrous oxide emissions, studies show.

The corn and ethanol industries insist that rapid growth in ethanol — which now consumes more than 40% of the U.S. corn crop —  is a net environmental benefit, and they strongly dispute research suggesting otherwise.

Since 2000, U.S. corn production has surged almost 50%, further adding to the crop’s climate impact. 

Yet the environmental costs of corn rarely make headlines or factor into political debates. Much of the dynamic traces back to federal policy — and to the powerful corn and ethanol lobby that helped shape it. 

The Renewable Fuel Standard, passed in the mid 2000s, required that gasoline be blended with ethanol, a biofuel that in the United States comes almost entirely from corn. That mandate drove up demand and prices for corn, spurring farmers to plant more of it. 

Many plant corn year after year on the same land. The practice, called “continuous corn,” demands massive amounts of nitrogen fertilizer and drives especially high nitrous oxide emissions. 

At the same time, federal subsidies make it more lucrative to grow corn than to diversify. Taxpayers have covered more than $50 billion in corn insurance premiums over the past 30 years, according to federal data compiled by the Environmental Working Group.

Researchers say proven conservation steps — such as planting rows of trees, shrubs and grasses in corn fields — could sharply reduce these emissions. But the Trump administration has eliminated many of the incentives that helped farmers try such practices. 

Experts say it all raises a larger question: If America’s most widely planted crop is worsening climate change, shouldn’t we begin growing it a different way?

How corn took over America

Corn has been a staple of U.S. agriculture for centuries, first domesticated by Native Americans and later used by European immigrants as a versatile crop for food and animal feed. Its production really took off in the 2000s after federal mandates and incentives helped turn much of America’s corn crop into ethanol.

Corn’s dominance — and the emissions that come with it — didn’t happen by accident. It was built through a high-dollar lobbying campaign that continues today.

In the late 1990s, America’s corn farmers were in trouble. Prices had cratered amid a global grain glut and the Asian financial crisis. A 1999 report by the Federal Reserve Bank of Minneapolis said crop prices had hit “rock bottom.”

In 2001 and 2002, the federal government gave corn farmers and ethanol producers a boost — first through the U.S. Department of Agriculture’s Bioenergy Program, which paid ethanol producers to increase their use of farm commodities for fuel. Then the 2002 Farm Bill created programs that continue to support ethanol and other renewable energy.

Corn growers soon after mounted an all-out campaign in Washington. Their goal: persuade Congress to require gasoline to be blended with ethanol. State and national grower groups lobbied relentlessly, pitching ethanol as a way to cut greenhouse gasses, reduce oil dependence and revive rural economies.

“We got down to a couple of votes in Congress, and the corn growers were united like never before,” recalled Jon Doggett, then the industry’s chief lobbyist, in an article published by the National Corn Growers Association. “I started receiving calls from Capitol Hill saying, ‘Would you have your growers stop calling us? We are with you.’ I had not seen anything like it before and haven’t seen anything like it since.”

Their persistence paid off. In 2005, Congress created the Renewable Fuel Standard (RFS), which requires that a certain amount of ethanol be blended into U.S. gasoline each year. Two years later, lawmakers expanded it further. The policy transformed the market: The amount of corn used for ethanol domestically has more than tripled in the past 20 years.

When demand for corn spiked as a result of the RFS, it pushed up prices worldwide, said Tim Searchinger, a researcher at Princeton University’s School of Public and International Affairs. The result, Searchinger said, is that more land around the world got cleared to grow corn. That, in turn, resulted in more emissions. 

That lobbying brought clout. “King Corn” became a political force, courted by presidential hopefuls and protected by both parties. Since 2010, national corn and ethanol trade groups have spent more than $55 million on lobbying and millions more on political donations, according to campaign finance records analyzed by Floodlight. 

In 2024 alone, those trade groups spent twice as much on lobbying as the National Rifle Association. Major industry players — Archer Daniels Midland, Cargill and ethanol giant POET among them — have poured even more into Washington, ensuring the sector’s voice remains one of the loudest in U.S. agriculture.

Now those same groups are pushing for the next big prize: expanding higher-ethanol gasoline blends and positioning ethanol-based jet fuel as aviation’s “low-carbon” future.

Research undercuts ethanol’s clean fuel claims

Corn and ethanol trade groups didn’t make their officials available for interviews.

But on their websites and in their literature, they have promoted corn ethanol as a climate-friendly fuel. 

The Renewable Fuels Association cites government and university research that finds burning ethanol reduces greenhouse gas emissions by roughly 40-50% compared with gasoline. The ethanol industry says the climate critics have it wrong — and that most of the corn used for fuel comes from better yields and smarter farming, not from plowing up new land. The amount of fertilizer required to produce a bushel of corn has dropped sharply in recent decades, they say.

“Ethanol reduces carbon emissions, removing the carbon equivalent of 12 million cars from the road each year,” according to the Renewable Fuels Association.

Growth Energy, a major ethanol trade group, said in a written statement that U.S. farmers and biofuel producers are “constantly finding new ways to make their operations more efficient and more environmentally beneficial,” using things like cover crops to reduce their carbon footprint.

But some research tells a different story.

A recent Environmental Working Group report finds that the way corn is grown in much of the Midwest — with the same fields planted in corn year after year — carries a heavy climate cost.

Research in 2022 by agricultural land use expert Tyler Lark and colleagues links the Renewable Fuel Standard to expanded corn cultivation, heavier fertilizer use, worsening water pollution and increased emissions. Scientists typically convert greenhouse gases like nitrous oxide and methane into their carbon dioxide equivalents — or carbon intensity — so their warming impacts can be compared on the same scale.

“The carbon intensity of corn ethanol produced under the RFS is no less than gasoline and likely at least 24% higher,” the authors concluded.

Lark’s research has been disputed by scientists at Argonne National Laboratory, Purdue University and the University of Illinois, who published a formal rebuttal arguing the study relied on “questionable assumptions” and faulty modeling — a charge Lark’s team has rejected.

A 2017 report by the U.S. Government Accountability Office found that the RFS was unlikely to meet its greenhouse gas goals because the U.S. relies predominantly on corn ethanol and produces relatively little of the cleaner, advanced biofuels made from waste. 

The problem isn’t just emissions, researchers say. Corn ethanol requires millions of acres that could instead be used for food crops or more efficient energy sources. One recent study found that solar panels can generate as much energy as corn ethanol on roughly 3% of the land. 

“It’s just a terrible use of land,” Searchinger, the Princeton researcher, said of ethanol. “And you can’t solve climate change if you’re going to make such terrible use of land.”

Most of the country’s top crop isn’t feeding people. More than 40% of U.S. corn goes to ethanol. A similar amount is used to feed livestock, and just 12% ends up as food or in other uses.

As corn production rises, so have emissions 

Globally, corn production doubled from 2000 to 2021. 

That growth has been fueled by fertilizer, which emits nitrous oxide that can linger in the atmosphere for more than a century. That eats away at the ozone layer, which blocks most of the sun’s harmful ultraviolet radiation.

Global emissions have soared alongside corn production. Between 1980 and 2020, nitrous oxide emissions from human activity climbed 40%, the Global Carbon project found. 

In the United States, nitrous oxide emissions from agriculture in 2022 were equal to roughly 262 million metric tons of carbon dioxide, according to the EPA’s inventory of greenhouse gas emissions. That’s equivalent to putting almost 56 million passenger cars on the road.

The biggest increases are coming straight from the Corn Belt.

Ethanol’s climate footprint isn’t the only concern. The nitrogen used to grow corn and other crops is also a key source of drinking water pollution.

According to a new report by the Alliance for the Great Lakes and Clean Wisconsin, more than 90% of nitrate contamination in Wisconsin’s groundwater is linked to agricultural sources — mostly synthetic fertilizer and manure. 

The same analysis estimates that in 2022, farmers applied more than 16 million pounds of nitrogen beyond what crops needed, sending runoff into wells, streams and other water systems.

For families like Tyler Frye’s, that hits close to home. In 2022, Frye and his wife moved into a new home in the rural village of Casco, Wisconsin, about 20 miles east of Green Bay. A free test soon afterward found their well water had nitrate levels more than twice the EPA’s safe limit. “We were pretty shocked,” he said. 

Frye installed a reverse-osmosis system in the basement and still buys bottled water for his wife, who is breastfeeding their daughter, born in July.

One likely culprit, he suspects, are the cornfields less than 200 yards from his home. 

“Crops like corn require a lot of nitrogen,” he said. “A lot of that stuff, I assume, is getting into the well water and surface water.”

When he watches manure or fertilizer being spread on nearby fields, he said, one question nags him: “Where does that go?”

What cleaner corn could look like

Reducing corn’s climate footprint is possible — but the farmers trying to do it are swimming against the policy tide.

The One Big Beautiful Bill Act, backed by President Donald Trump and congressional Republicans, strips out the provisions of President Joe Biden’s Inflation Reduction Act that had rewarded farmers for climate-friendly practices.

And in April, Trump’s USDA canceled the $3 billion Partnerships for Climate-Smart Commodities initiative, a grant program designed to promote farming and forestry practices to improve soil and reduce greenhouse gas emissions. The agency said that the program’s administrative costs meant too little money was reaching farmers, while Agriculture Secretary Brooke Rollins dismissed it as part of the “green new scam.” 

University of Iowa professor Silvia Secchi said the rollback of the Climate-Smart program has already given farmers “cold feet” about adopting conservation practices. “The impact of this has been devastating,” said Secchi, a natural resources economist who teaches at the university’s School of Earth, Environment and Sustainability.

Research shows what’s possible if farmers had support. In its recent report, the Environmental Working Group found that four proven conservation practices — including planting trees, shrubs and hedgerows in corn fields — could make a measurable difference. 

Implementing those practices on just 4% of continuous corn acres across Illinois, Iowa, Minnesota and Wisconsin would cut total greenhouse gas emissions by the equivalent of taking more than 850,000 gasoline cars off the road, EWG found.

Despite setbacks at the federal level, some farmers are already showing what a more climate-friendly Corn Belt could look like.

In northern Iowa, Wendy Johnson farms 1,200 acres of corn and soybeans with her father. On 130 of those acres, she’s trying something different: She’s planting fruit and nut trees, organic grains, shrubs and other plants that need little or no nitrogen fertilizer. 

“The more perennials we can have on the ground, the better it is for the climate,” she said. 

Across the rest of the farm, they enrich the soil by rotating crops and planting cover crops. They’ve also converted less productive parts of the fields into “prairie strips” — bands of prairie grass that store carbon and require no fertilizer. 

Under the now-canceled Climate-Smart grant program, they were supposed to receive technical assistance and about $20,000 a year to expand those practices. The grant program was terminated before they got any of the money.

“It’s hard to take risks on your own,” Johnson said. “That’s where federal support really helps. Because agriculture is a high-risk occupation.”

The economics still favor business as usual. Johnson knows that many Midwestern corn growers feel pressure to maximize yields, keeping them hooked on corn — and nitrogen fertilizer. 

“I think a lot of farmers around here are very allergic to trees,” she joked. 

In southeast Iowa, sixth-generation farmer Levi Lyle, who mixes organic and conventional methods across 290 acres, uses a three-year rotation, extensive cover crops and a technique called roller-crimping — flattening rye each spring to create a mulch that suppresses weeds, feeds the soil and reduces fertilizer needs. 

“The roller crimping of cover crops is a huge, huge opportunity to sequester more carbon, improve soil health, save money on chemicals and still get a similar yield,” he said.

But farmers get few government incentives to take such climate-friendly steps, Lyle said. “There is a lack of seriousness about supporting farmers to implement these new practices,” he said. 

And without federal programs to offset the risk, the innovations that Lyle and Johnson are trying remain exceptions — not the norm.

Many farmers still see prairie strips or patches of trees as a waste, said Luke Gran, whose company helps Iowa farmers establish perennials.

“My eyes do not lie,” Gran said. “I have not seen extensive change to cover cropping or tillage across the broad acreage of this state that I love.”

The next corn boom?

Despite mounting research about corn’s climate costs, industry groups are pushing for policies to boost ethanol demand. 

One big priority: pushing a bill to require that new cars are able to run on gas with more ethanol than what’s commonly sold today.

Corn and biofuel trade groups have also been pressing Democrats and Republicans in Congress for legislation to pave the way for ethanol-based jet fuel. While use of such “sustainable” aviation fuel is still in its early stages domestically, corn and biofuel associations have made developing a market for it a top policy priority. 

Secchi, the Iowa professor, says it’s easy to see why ethanol producers are trying to expand their market: The growth in electric vehicles threatens long-term gasoline sales.

Researchers warn that producing enough ethanol-based jet fuel could trigger major land use shifts. A 2024 World Resources Institute analysis found that meeting the federal goal of 35 billion gallons of ethanol jet fuel would require about 114 million acres of corn — roughly 20% more corn acreage than the U.S. already plants for all purposes. That surge in demand, the authors concluded, would push up food prices and worsen hunger.

Secchi calls that scenario a climate and land use “disaster.” Large-scale use of ethanol-based aviation fuel, she said, would mean clearing even more land and pouring on even more nitrogen fertilizer, driving up greenhouse gas emissions. 

“The result,” she said, “would be essentially to enshrine this dysfunctional system that we created.”

Jessika Trancik, a professor in MIT’s Institute for Data, Systems, and Society, has been named the new director of the Sociotechnical Systems Research Center (SSRC), effective July 1. The SSRC convenes and supports researchers focused on problems and solutions at the intersection of technology and its societal impacts.

Trancik conducts research on technology innovation and energy systems. At the Trancik Lab, she and her team develop methods drawing on engineering knowledge, data science, and policy analysis. Their work examines the pace and drivers of technological change, helping identify where innovation is occurring most rapidly, how emerging technologies stack up against existing systems, and which performance thresholds matter most for real-world impact. Her models have been used to inform government innovation policy and have been applied across a wide range of industries.

“Professor Trancik’s deep expertise in the societal implications of technology, and her commitment to developing impactful solutions across industries, make her an excellent fit to lead SSRC,” says Maria C. Yang, interim dean of engineering and William E. Leonhard (1940) Professor of Mechanical Engineering.

Much of Trancik’s research focuses on the domain of energy systems, and establishing methods for energy technology evaluation, including of their costs, performance, and environmental impacts. She covers a wide range of energy services — including electricity, transportation, heating, and industrial processes. Her research has applications in solar and wind energy, energy storage, low-carbon fuels, electric vehicles, and nuclear fission. Trancik is also known for her research on extreme events in renewable energy availability.

A prolific researcher, Trancik has helped measure progress and inform the development of solar photovoltaics, batteries, electric vehicle charging infrastructure, and other low-carbon technologies — and anticipate future trends. One of her widely cited contributions includes quantifying learning rates and identifying where targeted investments can most effectively accelerate innovation. These tools have been used by U.S. federal agencies, international organizations, and the private sector to shape energy R&D portfolios, climate policy, and infrastructure planning.

Trancik is committed to engaging and informing the public on energy consumption. She and her team developed the app carboncounter.com, which helps users choose cars with low costs and low environmental impacts.

As an educator, Trancik teaches courses for students across MIT’s five schools and the MIT Schwarzman College of Computing.

“The question guiding my teaching and research is how do we solve big societal challenges with technology, and how can we be more deliberate in developing and supporting technologies to get us there?” Trancik said in an article about course IDS.521/IDS.065 (Energy Systems for Climate Change Mitigation).

Trancik received her undergraduate degree in materials science and engineering from Cornell University. As a Rhodes Scholar, she completed her PhD in materials science at the University of Oxford. She subsequently worked for the United Nations in Geneva, Switzerland, and the Earth Institute at Columbia University. After serving as an Omidyar Research Fellow at the Santa Fe Institute, she joined MIT in 2010 as a faculty member.

Trancik succeeds Fotini Christia, the Ford International Professor of Social Sciences in the Department of Political Science and director of IDSS, who previously served as director of SSRC.

As a major contributor to global carbon dioxide (CO₂) emissions, the transportation sector has immense potential to advance decarbonization. However, a zero-emissions global supply chain requires re-imagining reliance on a heavy-duty trucking industry that emits 810,000 tons of CO₂, or 6 percent of the United States’ greenhouse gas emissions, and consumes 29 billion gallons of diesel annually in the U.S. alone.

A new study by MIT researchers, presented at the recent American Society of Mechanical Engineers 2024 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference, quantifies the impact of a zero-emission truck’s design range on its energy storage requirements and operational revenue. The multivariable model outlined in the paper allows fleet owners and operators to better understand the design choices that impact the economic feasibility of battery-electric and hydrogen fuel cell heavy-duty trucks for commercial application, equipping stakeholders to make informed fleet transition decisions.

“The whole issue [of decarbonizing trucking] is like a very big, messy pie. One of the things we can do, from an academic standpoint, is quantify some of those pieces of pie with modeling, based on information and experience we’ve learned from industry stakeholders,” says ZhiYi Liang, PhD student on the renewable hydrogen team at the MIT K. Lisa Yang Global Engineering and Research Center (GEAR) and lead author of the study. Co-authored by Bryony DuPont, visiting scholar at GEAR, and Amos Winter, the Germeshausen Professor in the MIT Department of Mechanical Engineering, the paper elucidates operational and socioeconomic factors that need to be considered in efforts to decarbonize heavy-duty vehicles (HDVs).

Operational and infrastructure challenges

The team’s model shows that a technical challenge lies in the amount of energy that needs to be stored on the truck to meet the range and towing performance needs of commercial trucking applications. Due to the high energy density and low cost of diesel, existing diesel drivetrains remain more competitive than alternative lithium battery-electric vehicle (Li-BEV) and hydrogen fuel-cell-electric vehicle (H2 FCEV) drivetrains. Although Li-BEV drivetrains have the highest energy efficiency of all three, they are limited to short-to-medium range routes (under 500 miles) with low freight capacity, due to the weight and volume of the onboard energy storage needed. In addition, the authors note that existing electric grid infrastructure will need significant upgrades to support large-scale deployment of Li-BEV HDVs.

While the hydrogen-powered drivetrain has a significant weight advantage that enables higher cargo capacity and routes over 750 miles, the current state of hydrogen fuel networks limits economic viability, especially once operational cost and projected revenue are taken into account. Deployment will most likely require government intervention in the form of incentives and subsidies to reduce the price of hydrogen by more than half, as well as continued investment by corporations to ensure a stable supply. Also, as H2-FCEVs are still a relatively new technology, the ongoing design of conformal onboard hydrogen storage systems — one of which is the subject of Liang’s PhD — is crucial to successful adoption into the HDV market.

The current efficiency of diesel systems is a result of technological developments and manufacturing processes established over many decades, a precedent that suggests similar strides can be made with alternative drivetrains. However, interactions with fleet owners, automotive manufacturers, and refueling network providers reveal another major hurdle in the way that each “slice of the pie” is interrelated — issues must be addressed simultaneously because of how they affect each other, from renewable fuel infrastructure to technological readiness and capital cost of new fleets, among other considerations. And first steps into an uncertain future, where no one sector is fully in control of potential outcomes, is inherently risky. 

“Besides infrastructure limitations, we only have prototypes [of alternative HDVs] for fleet operator use, so the cost of procuring them is high, which means there isn’t demand for automakers to build manufacturing lines up to a scale that would make them economical to produce,” says Liang, describing just one step of a vicious cycle that is difficult to disrupt, especially for industry stakeholders trying to be competitive in a free market. 

Quantifying a path to feasibility

“Folks in the industry know that some kind of energy transition needs to happen, but they may not necessarily know for certain what the most viable path forward is,” says Liang. Although there is no singular avenue to zero emissions, the new model provides a way to further quantify and assess at least one slice of pie to aid decision-making.

Other MIT-led efforts aimed at helping industry stakeholders navigate decarbonization include an interactive mapping tool developed by Danika MacDonell, Impact Fellow at the MIT Climate and Sustainability Consortium (MCSC); alongside Florian Allroggen, executive director of MITs Zero Impact Aviation Alliance; and undergraduate researchers Micah Borrero, Helena De Figueiredo Valente, and Brooke Bao. The MCSC’s Geospatial Decision Support Tool supports strategic decision-making for fleet operators by allowing them to visualize regional freight flow densities, costs, emissions, planned and available infrastructure, and relevant regulations and incentives by region.

While current limitations reveal the need for joint problem-solving across sectors, the authors believe that stakeholders are motivated and ready to tackle climate problems together. Once-competing businesses already appear to be embracing a culture shift toward collaboration, with the recent agreement between General Motors and Hyundai to explore “future collaboration across key strategic areas,” including clean energy. 

Liang believes that transitioning the transportation sector to zero emissions is just one part of an “energy revolution” that will require all sectors to work together, because “everything is connected. In order for the whole thing to make sense, we need to consider ourselves part of that pie, and the entire system needs to change,” says Liang. “You can’t make a revolution succeed by yourself.”

Climate anxiety affects nearly half of young people aged 16-25. Students like second-year Rachel Mohammed find hope and inspiration through her involvement in innovative climate solutions, working alongside peers who share her determination. “I’ve met so many people at MIT who are dedicated to finding climate solutions in ways that I had never imagined, dreamed of, or heard of. That is what keeps me going, and I’m doing my part,” she says.

Hydrogen-fueled engines

Hydrogen offers the potential for zero or near-zero emissions, with the ability to reduce greenhouse gases and pollution by 29 percent. However, the hydrogen industry faces many challenges related to storage solutions and costs.

Mohammed leads the hydrogen team on MIT’s Electric Vehicle Team (EVT), which is dedicated to harnessing hydrogen power to build a cleaner, more sustainable future. EVT is one of several student-led build teams at the Edgerton Center focused on innovative climate solutions. Since its founding in 1992, the Edgerton Center has been a hub for MIT students to bring their ideas to life.

Hydrogen is mostly used in large vehicles like trucks and planes because it requires a lot of storage space. EVT is building their second iteration of a motorcycle based on what Mohammed calls a “goofy hypothesis” that you can use hydrogen to power a small vehicle. The team employs a hydrogen fuel cell system, which generates electricity by combining hydrogen with oxygen. However, the technology faces challenges, particularly in storage, which EVT is tackling with innovative designs for smaller vehicles.

Presenting at the 2024 World Hydrogen Summit reaffirmed Mohammed’s confidence in this project. “I often encounter skepticism, with people saying it’s not practical. Seeing others actively working on similar initiatives made me realize that we can do it too,” Mohammed says.

The team’s first successful track test last October allowed them to evaluate the real-world performance of their hydrogen-powered motorcycle, marking a crucial step in proving the feasibility and efficiency of their design.

MIT’s Sustainable Engine Team (SET), founded by junior Charles Yong, uses the combustion method to generate energy with hydrogen. This is a promising technology route for high-power-density applications, like aviation, but Yong believes it hasn’t received enough attention. Yong explains, “In the hydrogen power industry, startups choose fuel cell routes instead of combustion because gas turbine industry giants are 50 years ahead. However, these giants are moving very slowly toward hydrogen due to its not-yet-fully-developed infrastructure. Working under the Edgerton Center allows us to take risks and explore advanced tech directions to demonstrate that hydrogen combustion can be readily available.”

Both EVT and SET are publishing their research and providing detailed instructions for anyone interested in replicating their results.
