Environmental and community advocates in Massachusetts argue that making too much room for biofuels in a pending state plan to decarbonize heating systems would slow the transition from fossil fuels and cause more pollution than a plan that prioritizes electric heat pumps.

As the state works on the creation of a Clean Heat Standard, a report released last month by Greater Boston Physicians for Social Responsibility raises questions about the effects using biodiesel in fuel-oil heating systems could have on air quality and public health, saying there is not enough information available about the pollutants released in the process. 

Advocates say there is no such uncertainty about electric heat pumps, which create no direct emissions and should therefore be heavily favored in the new state policy. 

“We absolutely think the thumb should be on the scale of electrification,” said Larry Chretien, executive director of the Green Energy Consumers Alliance. “If they give credit to biofuels, it ought to be conditional.”

Oil heating is much more prevalent in the Northeast than in the rest of the country. In Massachusetts, 22% of households are heated with oil, as compared to less than 5% nationwide. Moving homes and businesses off oil heat, therefore, is an important element of the state’s plan to achieve net-zero emissions by 2050, which sets a target of reducing emissions from heating by 93% from 1990 levels in that timeframe. 

The process of developing a Clean Heat Standard began when then-Gov. Charlie Baker convened the Commission on Clean Heat in 2021. In 2022, the board recommended the creation of the standard, which was also included in the state’s Clean Energy and Climate Plan for 2050, released later that year. A stakeholder process began in 2023, and in the fall of that year the state released a draft framework for the standard that included the expectation of issuing credits for some biofuel use. 

Open questions about public health

The program is expected to require gas utilities and importers of heating oil and propane to provide an increasing proportion of clean heating services like home heat pumps, networked geothermal, and other options, or buy credits from other parties that have implemented these solutions. 

Whether the other options that qualify as clean heat will include biofuels — fuels derived from renewable, organic sources — has been a matter of contention since the idea for the system was first raised.

Climate advocates have tended to oppose the inclusion of much, if any, biofuel in the standard. Though biodiesel creates lower lifetime greenhouse gas emissions than its conventional counterpart, the recent Greater Boston Physicians for Social Responsibility report contends that there are many unanswered questions about how burning biodiesel impacts public health. 

“Given the sheer amount of doubt, there’s more research that should clearly be done before these fuels are subsidized by the state government,” said report author Carrie Katan, who also works as a Massachusetts policy advocate for the Green Energy Consumers Alliance, but compiled the report as an independent contractor for the physicians group. 

The physicians’ report notes a study by Trinity Consulting Group that found significant health benefits to switching from fossil diesel to biodiesel for building heating. The physicians’ report, however, questions the methodology used in that study, claiming it cherrypicks data and fails to cite sources. 

Katan’s report also notes that the health impacts of biofuels can vary widely depending on the organic matter used to create them, and points out that most of the research on burning biofuels is focused on the transportation sector. 

Climate advocates also argue that embracing biofuels in a Clean Heat Standard would unnecessarily prolong the transition to electric heat pumps while encouraging the continued burning of fossil heating oil. Typically, a heating oil customer using biodiesel receives a blend that is no more than 20% biofuel. Providing credit for that fraction of biofuel would therefore improve the economics of the entire heating oil system, contrary to the overall emissions reduction goals of the policy, Chretien said.

“We’re trying to create a system that is rewarding steps towards greenhouse gas reduction,” he said. 

Making the case for biofuel

Advocates of biofuels, however, say they are confident that existing science makes a solid case for the health and environmental benefits of biodiesel. 

“There’s a decades-long body of work showing the overall benefits to public health of biofuels, specifically biodiesel,” said Floyd Vergara, a consultant for Clean Fuels Alliance America, a national trade association representing the biodiesel, renewable diesel and sustainable aviation fuel industries.

Vergara, who was involved in the Trinity Consulting study, called out in the physicians’ report, also defended the methodologies and sourcing of that paper. 

Further, he said, though biodiesel is typically limited to 20% in current blends, it is quite possible to run a heating system entirely on biofuel, with just a few tweaks to the equipment. These conversions could yield immediate reductions in emissions, he said, rather than waiting for the slower process of replacing thousands of heating oil systems with electric heat pumps.

The difference could be particularly acute in low-income or other traditionally disadvantaged neighborhoods, where many residents can not afford to make the switch to heat pumps, he said. 

“You’re getting those benefits immediately, and you’re getting them while the states are pursuing zero-emissions technologies,” he said.

State environmental regulators expect to release a full draft of the clean heat standard for public comment sometime this winter.

Massachusetts environmental advocates hope a provision in the state’s new climate law could be a final blow to a proposed expansion of private jet facilities at a suburban airport. 

Opponents say adding 500,000 square feet of hangar space at Hanscom Field, a general aviation airport that serves private and corporate aircraft in a town 20 miles outside of Boston, will inevitably mean more flights — mostly private jet travel to luxury locations — which will increase climate pollution with minimal public benefit.

“This is an industry that is highly polluting and yet serves only a very narrow slice of the public,” said Alex Chatfield, a local social worker and an activist fighting the project. 

The expansion plans have been in the works since 2021, but progress slowed in June after state regulators rejected the planners’ first environmental impact report. Since then, state lawmakers passed a new law requiring state agencies and boards, including the state port authority, to consider the impact of greenhouse gas emissions in their decisions. 

The measure does not directly prohibit the Massachusetts Port Authority from proceeding with projects such as the Hanscom plan, but it does leave the agency vulnerable to legal action should it forge ahead without being able to show it weighed the likely greenhouse gas emissions against the benefits of the plan. 

Much-needed hangars

The expansion plan started with Massport, which oversees operations at Hanscom as well as Boston’s Logan International Airport and Worcester Regional Airport. In 2021, the agency released a request for proposals to develop “much-needed hangars” at the airport, said Massport spokesperson Jennifer Mehigan. A plan submitted by North Airfield Ventures and Runway Realty Ventures won the bid. 

The proposed facilities would be built on 47 acres of land, some of which is already owned by the developers and some of which would be leased to them by Massport. The project comprises 17 new hangars, the rehabilitation of a historic Navy hangar on the site, and fuel storage facilities. 

Planners argue the development would be environmentally beneficial, because the structures would be designed for net-zero energy use and built to LEED Gold standards, and buildings and equipment would be electrified whenever possible. They also claim the additional capacity would help cut down on emissions from so-called “ferry flights,” in which a plane hangared elsewhere flies to Hanscom to pick up passengers and then returns to its home airport at the end of the trip. 

Opponents, however, argue that more hangars will inevitably mean more flights. These flights, they say, are likely to be private jet travel to luxury locations, generating emissions for the benefit of just a privileged few. One report, by Washington, D.C.-based Institute for Policy Studies, found that 31,600 private flights departed Hanscom during an 18-month period in 2022 and 2023, and that roughly half of those were bound for high-end vacation destinations like the Bahamas, Palm Beach, and Nantucket.

“It’s very well known that private jets are the most polluting form of transportation per passenger ever devised,” Chatfield said. “It is on a scale that is really hard to imagine.”

State environmental regulators are also skeptical. The state response to the developers’ first environmental impact report, referred to the “fanciful nature of the proponents’ ‘ferry flight theory,’” pointing to a study that found only 132 ferry flights actually occurred at Hanscom rather than the 3,500 developers claimed. Regulators also suggested new hangars at Hanscom were unlikely to attract planes to relocate, and therefore would not reduce what ferry flights do occur.

The developers can resubmit their environmental impact report, addressing the state’s concerns. One of the founders of North Airfield Ventures said the company declines to comment on its plans at this time. 

Factoring in climate impacts

In the months since the state’s order was released, legislators created another obstacle for the project. 

As Massachusetts attempts to reach its goal of net-zero carbon emissions, an ongoing mundane-yet-important challenge has been the fact that some crucial state agencies and boards have lacked the authority to factor climate impacts in their decisions. These bodies were founded well before the climate crisis became such a pressing public policy question, and thus their rules never required or authorized them to consider greenhouse gas emissions or other climate impacts in their decision-making. 

In recent years, attempts have been made to integrate climate change mitigation into more statewide policies and processes. A climate law enacted in 2021 requires the administration to set greenhouse gas reduction goals to be realized by the state’s three-year energy efficiency plans, which were initially intended only to reduce the cost and quantity of electricity, gas, and oil used. The same bill instructed public utilities regulators to consider greenhouse gas impact as part of their decisions. 

“The department up to that point had just focused on reliability and affordability,” said state Sen. Michael Barrett, chair of the legislature’s committee on telecommunications, utilities, and energy, and one of the main authors of both the 2021 and 2024 climate bills. “I have wanted to reorient state agencies that don’t seem to have gotten the memo about climate change being an existential crisis.”

The latest bill included more such provisions, authorizing the Board of Building Regulations and Standards to give preference to building materials that boost emissions reductions, and requiring Massport to consider the greenhouse gas impacts of its decisions.

“I hope that Massport appreciates that what is done today on climate is inadequate, and I hope it also appreciates that the policies have changed,” said Barrett. “I don’t pretend to be able to predict particular outcomes on particular projects, but I do know that Massport needs to take this seriously.”

A trailblazing regional greenhouse gas partnership on the East Coast is considering possible changes or expansion that would allow it to keep building on its success — and the stakes grew higher last month with the reelection of Donald Trump.

The 11-state Regional Greenhouse Gas Initiative, established in 2005, is the country’s first regional cap-and-invest system for reducing carbon emissions from power generation. Since 2021, administrators have been conducting a program review, analyzing its performance since the last review in 2017 and weighing potential adjustments to make sure it continues to deliver benefits to member states.

The role of such programs is more crucial as Trump’s pledges to roll back federal climate action leaves it up to cities, states, and the private sector to maintain the country’s momentum on clean energy over the next four years. In RGGI, as the regional initiative is known, states have a potential model for scaling their impact through collaboration. 

“RGGI has not only been an effective climate policy, it’s been an extraordinary example of how states can work together on common goals,” said Daniel Sosland, president of climate and energy nonprofit Acadia Center. “It is a major vehicle for climate policy now in the states, more than it might have seemed before the election.” 

How RGGI works

RGGI sets a cap for total power plant carbon emissions among member states. Individual generators must then buy allowances from the state, up to the total cap, for each ton of carbon dioxide they produce in a year. The cap lowers over time, forcing power plants to either reduce emissions or pay more to buy allowances from a shrinking pool.

States then reinvest the proceeds from these auctions into programs that further reduce emissions and help energy customers, including energy efficiency initiatives, direct bill assistance, and renewable energy projects. Since 2008, RGGI has generated $8.3 billion for participating states, and carbon dioxide emissions from power generation in the nine states that have consistently participated fell by about half between 2008 and 2021, a considerably faster rate than the rest of the country. 

“It has really thrived and been really effective across multiple administrations,” said Jackson Morris, state power sector director with the Natural Resources Defense Council. “RGGI is a winning model. It’s not theoretical — we’ve got numbers.”

Currently, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont are part of the program. Virginia joined RGGI in 2021, but in 2023 Gov. Glenn Youngkin repealed the state’s participation, a move immediately challenged in court; a judge ruled last month that the governor lacked the authority to withdraw the state from initiative, though a spokesman for the governor has declared the state’s intention to appeal. 

There is widespread agreement that RGGI will endure despite likely federal hostility to climate measures. There was no attempt to take direct action against it during Trump’s first term, nor has there been any concerted industry opposition, said Conservation Law Foundation president Bradley Campbell, who was involved in the founding of RGGI when he was commissioner of the New Jersey Department of Environmental Protection.

Supporters also note that the program has historically had broad bipartisan support: Participating states have been led through the years by both Republican and Democratic governors and legislatures. 

Politics has had some influence over the years, though only at the margins. New Jersey, a founding member of RGGI, left in 2011 when Chris Christie was governor, but returned in 2020 following an executive order from his successor. Pennsylvania joined in 2022 through an executive order from the governor, but its participation is now being challenged in court. 

Still, RGGI’s foundations are solid and will remain so, experts said. 

“The basic infrastructure has weathered the political winds over the decades,” Campbell said.

Looking forward

Nonetheless, RGGI will need to make some carefully thought-out program design decisions during its current review to make an impact in the face of falling federal support for decarbonization. 

One question under consideration is whether to maintain the existing trajectory for the overall emissions cap for the program — a reduction of 30% between 2020 and 2030, then holding steady thereafter — or to continue lowering the limit after 2030. 

The RGGI states are also contemplating a possible change to the compliance schedule that would require power generators to acquire allowances worth 100% of their carbon emissions each year, and certify compliance annually. The current system calls for certification every three years, and only mandates allowances equivalent to half of carbon emissions for the first two years of each period.

The program is looking for ways to appeal to potential new participant states that have less aggressive decarbonization goals than current member states without watering down the program’s overall impact on decarbonization, said Acadia Center policy analyst Paola Tamayo. Acadia suggested possible program mechanisms such as giving proportionately more allowances to states with more stringent emissions targets to incentivize tighter limits.

“At this point it is critical for states to maintain a high level of ambition when it comes to programs like RGGI,” Tamayo said. “There are different mechanisms that they can implement to accommodate other states.”

The program review is expected to yield a model rule some time over the winter, though updates may be made into the spring as the RGGI states receive and consider feedback on how to accommodate potential new participants.  

States will also need to maintain and strengthen their own climate policies to magnify the impact of RGGI, Campbell said. He pointed to Massachusetts, where Gov. Maura Healey needs to show “bolder leadership,” he said, and Maine and Vermont, where the Conservation Law Foundation has filed lawsuits in an attempt to compel the states to meet their own carbon reduction deadlines. 

“It’s especially important that the states that have strong emissions reduction mandates speed up the implementation of their climate laws,” he said. “State leadership on these issues is going to be more important than ever.”

A Massachusetts university is developing technology that aims to use lasers to drastically cut emissions and energy use from Maine’s paper and pulp industry. 

Worcester Polytechnic Institute recently received a $2.75 million U.S. Department of Energy grant to help ready the industrial drying technology for commercial use.

“We are all excited about this — this is potentially a groundbreaking technology,” said Jamal Yagoobi, founding director of the institute’s Center for Advanced Research in Drying.

In Maine, the paper and pulp business generates about 1 million metric tons of carbon dioxide emissions each year, roughly half of the state’s industrial emissions. Much of these emissions come from the process of drying mashed, pressed, and rolled wood pulp to yield paper products. The emissions come mainly from three major operations across the state; three additional facilities contribute smaller amounts.

These plants’ emissions will need to be addressed if Maine is to reach its goal of going carbon neutral by 2045. Furthermore, each of these plants is located in an area with an above-average population of low-income residents, according to data assembled by Industrious Labs, an environmental organization focused on the impact of industry. And two are located in areas with a higher-than-average risk of cancer from air toxins, suggesting a correlation between their operations and the incidence of cancer in the area. 

At the same, the paper and pulp industry remains economically important to Maine, said Matt Cannon, state conservation and energy director for the Maine chapter of the Sierra Club. 

“It’s got real union jobs — the paper industry is still very important to our community,” he said. 

Worcester Polytechnic’s drying research center has been working on ways to dry paper, pulp, and other materials using the concentrated energy found in lasers. The lasers Yagoobi’s team is using are not the lasers of the public imagination, like a red beam zapping at alien enemies. Though the lasers are quite strong — they can melt metal, Yagoobi says — they are dispersed over a larger area, spreading out the energy to evenly and gently dry the target material. 

Testing on food products has shown that the technology can work. Now, researchers need to learn more about how the laser energy affects different materials to make sure the product quality is not compromised during the drying process. 

“For paper, it’s important to make sure the tensile strength is not degrading,” Yagoobi said. “For food products, you want to make sure the color and sensory qualities do not degrade.”

Therefore, before the system is ready for a commercial pilot, the team has to gather a lot more data about how much laser energy is incident on different parts of the surface and how deeply the energy penetrates different materials. Once gathered, this data will be used to determine what system sizes and operating conditions are best for different materials, and to design laser modules for each intended use. 

Once these details are worked out, the laser technology can be installed in new commercial-scale drying equipment or existing systems. “This particular technology will be easy to retrofit,” Yagoobi said. 

Industrial sources were responsible for about 1.3 billion metric tons of carbon dioxide emissions in the United States in 2023, about 28% of the country’s overall emissions, according to the U.S. Energy Information Administration. Heating processes, often powered by natural gas or other fossil fuels, are responsible for about half of those emissions, said Evan Gillespie, one of the co-founders of Industrious Labs. Many industrial drying processes require high temperatures that have traditionally been hard to reach without fossil fuels, giving the sector a reputation as hard to decarbonize, Gillespie said.

“The key challenge here is: How do you remove natural gas as a heating source inside industrial facilities?” said Richard Hart, industry director at the American Council for an Energy-Efficient Economy. “The scale of what is happening in industry is enormous, and the potential for change is very powerful.”

To make the new technology effective, industry leaders and policymakers will need to commit to reinvesting in old facilities, Gillespie noted. And doing so will be well worth it by strengthening an economically important industry, keeping jobs in place, and creating important environmental benefits, he added.

“There’s often this old story of tensions between climate and jobs,” Gillespie said. “But what we’re trying to do is modernize these facilities and stabilize them so they’ll be around for decades to come.”

Nearly a year after Massachusetts regulators laid out a vision for the state’s evolution from natural gas distribution to clean energy use, lawmakers are coalescing around legislation that would start converting principles into policy. 

The wide-ranging climate bill includes several provisions that would allow utilities to explore alternatives to gas and empower regulators to place more limits on the expansion and continuation of natural gas infrastructure, changes that supporters say are critical to a successful transition away from fossil fuels. 

“This bill is a major first step in empowering [regulators] to do something rather than just rubber stamping the utilities’ plans,” said Lisa Cunningham, co-founder of ZeroCarbonMA.

Natural gas is currently the primary heating source for half the homes in Massachusetts, a number that needs to drop if the state is going to meet its ambitious climate goal of net-zero emissions by 2050, advocates and state leaders say. In 2020, the state department of public utilities opened an investigation into the role natural gas utilities would play in the transition to cleaner energy. In December 2023, the department issued a lengthy order concluding that the state must move “beyond gas” and outlining a broad framework for making the shift. 

Lawmakers attempted to start turning these general ideas into binding law earlier this year, but the legislative session closed at the end of July before the Senate and House reconciled the differences between their versions of a climate bill. Legislators returned to work this fall and hammered out an agreement, and the Senate passed the resulting bill last month. The House speaker has said the body will vote when it returns to formal session later this year. The bill is generally expected to pass and be signed into law. 

“A lot of people were skeptical we’d get a bill at all, but I’m happy with where this bill ended up,” said Kyle Murray, Massachusetts program director for climate nonprofit Acadia Center. “It shows a step toward that needed urgency.”

At the heart of the bill’s energy transition provisions is a change to the definition of a natural gas utility that allows the companies to also provide geothermal power. Networked geothermal — systems that draw heat from the earth and deliver it to a group of buildings — is widely seen as a promising alternative to natural gas, and both National Grid and Eversource have pilot projects in the works. However, current law prevents the utilities from pursuing such projects without specific authorization from regulators. The climate bill would remove this barrier, making it easier for gas companies to explore new approaches to business.

“The gas utilities deeply need a new business model that can help them step into the future,” said Audrey Schulman, founder of climate solutions incubator HEETlabs. “That allows them to potentially evolve.”

This definition change supports other provisions aimed at slowing the expansion of natural gas use in the state. The bill would end the requirement that natural gas utilities provide service to any customer in their service area who requests it, with few exceptions. Under the new law, utilities could decline these requests when other alternatives are available. 

The bill would also allow regulators to consider the impact of emissions when deciding whether to approve requests to expand natural gas service into new communities. In 2023, the state approved a request to bring gas service to the central Massachusetts town of Douglas. Regulators at the time noted that the decision works against the state’s goal of phasing out natural gas, but said the law gave them no choice but to approve the plan. Provisions in the climate bill would untie regulators’ hands in such cases in the future.

“The [Department of Public Utilities] can consider the public interest, including climate, it doesn’t have to say yes to more gas service,” said Amy Boyd Rabin, vice president of policy at the Environmental League of Massachusetts. And the inclusion of geothermal in gas utilities’ definition means “now there’s also something else to offer the customers.” 

Another major element of the bill would reform the state’s Gas System Enhancement Plans program, which encourages utilities to repair or replace pipes in the state’s aging and leak-prone natural gas distribution system. Clean energy advocates have often argued that these plans are problematic, investing billions of ratepayer dollars into shoring up a system that is increasingly obsolete. The climate bill would allow utilities to choose to retire segments of pipe rather than fixing them. 

“For the first time ever they are able to look at a pipe and say, ‘You know what, this is not worth the cost,’” Murray said. “We don’t want ratepayers shouldering the burden for a lot of stuff that’s not going to be useful in five to 10 years.”

Environmental advocates praised the bill’s gas provisions, and are already focusing on what more there is to be done. Several would have liked to see a more aggressive phasing out of Gas System Enhancement Plans, with a specific end date. Others champion an expansion of a pilot program that allows cities and towns to ban fossil fuel use in new construction and major renovations. 

“There is no reason why communities that want to enact this via home rule petition should be restricted from enacting the will of their constituents,” Cunningham said. 

In the meantime, advocates are ready to see the climate bill turning into reality. 

“There’s a lot of good stuff in there that will do a lot of good for the commonwealth,” Boyd Rabin says.
