A pending youth climate lawsuit in Maine represents the latest iteration of legal strategies aimed at holding states accountable for emissions-cutting targets. 

The case is one of a growing number responding to lagging progress on state climate laws that, in many cases, have now been on the books for years. What makes the Maine case unique is its targeted approach – focused on electric vehicle policy as a way to push the state forward on climate action. 

The case, filed earlier this year by the nonprofits Conservation Law Foundation (CLF), Sierra Club and Maine Youth Action, argues that the Maine Department and Board of Environmental Protection have fallen short on their legal duty to pass rules that will help achieve Maine’s required emissions reductions.

“There are countless solutions for tackling these various sources of climate-warming pollution,” said CLF senior attorney Emily Green, who is based in Portland, Maine. “But you need something more to make sure that it’s all enough, that it all adds up, and that’s where enforceable standards come in.” 

The Maine Attorney General’s office declined to comment, but has moved to dismiss the case. A ruling on next steps is now pending. 

Advocates focus on EV rulemaking

The case focuses on a 2019 state law that requires Maine to lower its greenhouse gas emissions 45% from 1990 levels by 2030 and 80% by 2050. 

Statutes like this are “where the rubber meets the road,” said Columbia Law School professor Michael Gerrard, faculty director of the Sabin Center for Climate Change Law. “The regulations are the teeth, the specifics on who needs to do what.” 

Such rules translate emissions goals into practical requirements for state executive agencies, processing legislative directive “into what polluters are required to do on a day-to-day basis,” said Jennifer Rushlow, an environmental law professor at Vermont Law and Graduate School.

Maine’s climate law said the state “shall adopt rules to ensure compliance” with the emissions targets, requiring those rules to prioritize reductions “by sectors that are the most significant sources.” 

Transportation contributes more than half of Maine’s emissions, and Maine’s climate plan prioritized electric vehicle adoption as a result. But the state is a long way off from its EV targets. It has about 12,300 EVs on the road now, with climate plan goals of 41,000 by next year and 219,000 by 2030. 

The CLF suit takes regulators to task for repeatedly failing to adopt California’s latest electric car and truck standards, which some states use as a more stringent alternative to federal rules. 

Maine has used California’s Advanced Clean Cars I rule for years, but voted earlier this year against adopting Advanced Clean Cars II, which would have required increasing EV sales in the state over the next several years. It’s also chosen twice not to consider adopting the Advanced Clean Trucks rule.

CLF notes that the state’s climate law requires the adoption of rules that are “consistent with the climate action plan,” first released in 2020. A roadmap for meeting the plan’s transportation goals strongly recommended adopting Clean Cars II, calling it “the most important regulatory driver in the electrification of Maine’s light-duty vehicles in the next two decades.”

State says harms are uncertain

In its motion to dismiss the CLF case, the state argues that Maine’s climate law does not require regulators to adopt all climate plan recommendations, or particular ones, as rules. 

The state has approved a handful of other rules under the climate law. Two focus on tracking emissions, and two others look at what Green called “narrow slices of the building sector,” the state’s second-largest emissions sector. These rules target hydrofluorocarbons and energy efficiency in appliances. 

In their motion, attorneys for the state quote a Maine Supreme Court decision from a separate environmental case earlier this year to argue that it is “simply ‘too uncertain’ … whether future harms will occur that will ‘directly and continuously impact’ any of Plaintiffs’ members.” 

CLF’s response lists a range of climate-linked harms that specific members of the plaintiff groups say they’ve already experienced, from increasing tick-borne illness and other health impacts to crop and flood damage.

“Climate change is here. Mainers are feeling the effects from a warming Gulf, from climate-driven storms,” Green said, adding that state lawmakers have repeatedly made similar statements in recent years. “Each day that passes with further inaction is a day wasted.” 

The state also argues that the “shifting sands” of state and federal climate policies that could affect Maine’s targets create too much uncertainty around harms from a current lack of transportation rules. 

In general, Gerrard said, such factors don’t negate the need for rulemaking. “We are way behind in reducing emissions, and so the fact that other things are happening isn’t going to solve the problem.” 

Green said that while Maine has made strides on expanding EV charging infrastructure, for example, “the actual standards are necessary to give that transition the push it needs.” 

“Binding rules can basically act as a backstop,” she said. “They can ensure the accountability that the investment and the rebates and the education and outreach, on their own, can’t do.” 

Narrower lawsuits get results 

The suit’s transportation focus is notable, experts said. “I would say the energy sector is targeted more frequently, and especially the fossil fuel sector,” Gerrard said. Other climate-adjacent transportation cases have focused on vehicle emissions standards, biofuel mandates or highway projects, he said. 

Rushlow sees the Maine case as a blend of a 2016 suit, also from CLF, which found that Massachusetts wasn’t fulfilling its 2008 emissions-cutting law, and a suit against the Hawaii Department of Transportation, where a recent settlement will require the decarbonization of Hawaii’s transportation sector by 2045. 

Rushlow worked with CLF on the Massachusetts case, but is not involved in the Maine suit and reviewed it after being asked to comment for this story. She said the Maine case lays out why having regulations on transportation emissions is “not just a wish” of the state climate council, but a legal requirement.

“The lawsuits that get really broad can get kind of lost to politics,” said Rushlow. “These lawsuits that are more narrow and focused on the language of particular state laws, I think, can stand a good chance.” 

She said there are also more “hooks” to do this at the state level than federally. Gerrard agreed that it’s easier to bring cases under specific statutes than “a constitutional provision or a common law doctrine.” 

Both the Hawaii case and the landmark Held v. Montana, which is now on appeal before that state’s Supreme Court, successfully took a state constitutional approach, using their legally given rights to a clean and healthful environment to push for climate progress. 

Victories of public opinion

Practical legal results aren’t the only positive impact these cases can have, Rushlow said: “There’s also outcomes in the zeitgeist and public opinion.” Though Juliana v. United States failed in court, she said, it “really drew a lot of attention to the future harm we’re causing our youth — and the current harm.”  

But she sees increasing potential for success among a greater share of climate lawsuits just in the past few years, as plaintiffs learn more about how courts are likely to receive different approaches. 

“It feels to me like progress is being made,” she said. “But the courts are never the first place you want to go when you’re looking for rapid, systemic change. They’re slow, they’re backward-looking, they’re conservative. And so it’s a challenging forum for the kind of change we need, and yet necessary.” 

In Maine, climate groups initially tried a regulatory petition to push for the passage of Clean Cars II. 

“When it became entirely evident that that was not going to happen, our hand was sort of forced,” Green said.

As Maine considers building a new toll highway to improve commutes in and out of Portland, a state climate working group is drafting strategies to reduce driving in the state.

State officials say the two efforts are not inherently at odds, but experts and advocates caution that continued highway expansion could reverse climate progress by encouraging more people to drive.

The parallel discussions in Maine raise a question that few states have yet grappled with: can governments keep expanding car infrastructure without putting climate goals out of reach?

Transportation is the largest source of greenhouse gas emissions in Maine and many other states. Electric vehicle adoption is growing, but not fast enough to solve the problem on its own, which is why an updated state climate plan is expected to include a new emphasis on public transit, walking, biking, and other alternatives to passenger vehicles.

Zak Accuardi, the director for mobility choices at the Natural Resources Defense Council, said the best way for states to invest in their road systems in the era of climate change is to not build new roads, but maintain and upgrade existing ones to accommodate more climate-friendly uses. 

“The states who are taking transportation decarbonization really seriously are really focused on reducing driving, reducing traffic,” Accuardi said, pointing to Minnesota and Colorado as examples. “Strategies that help support more people in making the choice to walk, bike or take transit — those policies are a really important complement to … accelerating the adoption of zero-emissions vehicles.” 

Slow progress on EV goals

Electric vehicles have been Maine’s primary focus to date in planning to cut back on transportation emissions. Goals in the state’s original 2020 climate plan included getting 41,000 light-duty EVs on the road in Maine by next year and 219,000 by 2030. The state is far behind on these targets. The climate council’s latest status report said there were just over 12,300 EVs or plug-in hybrid vehicles in Maine as of 2023. 

A 2021 state clean transportation roadmap for these goals recommended, among other things, the adoption of California’s Advanced Clean Cars II and Advanced Clean Trucks rules, which would require an increasing proportion of EV sales in the coming years. 

Maine regulators decided not to adopt Clean Cars II earlier this year in a 4-2 vote. A subsequent lawsuit from youth climate activists argued the state is reneging on its responsibility to meet its statutory climate goals by choosing not to adopt such rules. 

The original climate plan also aimed to cut Maine’s vehicle miles traveled (VMT), which measures how much people are driving overall, by 20% by 2030. The plan said getting there would require more transit funding, denser development to improve transit access, and broadband growth to enable remote work, but included little detail on these issues. It did not include the words “active transportation” at all. 

That appears poised to change in the state’s next four-year climate plan, due out in December. Recommendations from the state climate council’s transportation working group have drawn praise from advocacy groups like the Bicycle Coalition of Maine. 

New detail on non-car strategies

The group’s ideas include creating new state programs to support electric bike adoption, including in disadvantaged communities; paving 15 to 20 miles of shoulders on rural roads per year to improve safe access for cyclists and pedestrians; and, depending on federal funds, building at least 10 miles of off-road trails in priority areas by 2030. 

The group also recommended the state “develop targets related to increased use of transit, active transportation, and shared commuting that are consistent with Maine’s statutory emissions reduction goals.” 

In unveiling the recommendations, working group co-chair and Maine Department of Transportation chief engineer Joyce Taylor noted community benefits from road safety upgrades to accommodate these goals. 

“I think this also gets at housing and land use,” she said. “If you can get people to want to live in that community, that village, I think we could all say that it’s more economically vibrant when people are able to walk and bike in their village and feel like they can get around and it’s safe.” 

The Gorham Connector project would offer a new, tolled bypass around local roads as an alternative to upgrading those existing routes, an option that’s also been studied. State officials say the new road would smooth the flow of local traffic, including public transit. 

Towns aim to marry transit, housing, climate

Towns like Kittery, in southern Maine, have tried to focus on a more inclusive array of transportation strategies in their local work to cut emissions from passenger vehicles. 

Kittery town manager Kendra Amaral is a member of the climate council’s transportation group. She couldn’t comment on the state’s approach to the Gorham Connector, which is outside her region. But she said her town’s climate action plan, adopted this past May, “threads together” public transit, housing growth and emissions reductions. 

Stakeholders who worked on the plan, she said, strongly recommended ensuring that housing is in walkable or transit-accessible places. 

Amaral said the town has invested in new bus routes, commuter shuttles and road improvements to promote traffic calming and create safer bike and pedestrian access, as well as in EV growth. And she said Kittery was a model for parts of a new state law that enables denser housing development. 

“We can’t expect people to reduce (emissions) resulting from transportation without giving them options,” she said. But, she added, “there is no ‘one size fits all’ solution” for every community. “I believe we have to avoid the ‘all or nothing’ trap and work towards (the priorities) that get the best results for each community,” she said. 

‘Devil is in the details’

The Maine Turnpike Authority acknowledges the proposed Gorham Connector project in the Portland area would increase driving. But paired with improvements to transit and land-use patterns, they say the proposed limited-access toll road would decrease emissions overall — though research and other cases cast doubt on this possibility. 

“It’s possible for a project like this to be designed in a way that does produce favorable environmental outcomes,” Accuardi said, but “the devil is really in the details.” 

For example, he said the new road’s tolls should be responsive to traffic patterns in order to effectively reduce demand. If they’re too low, he said, the road will become jammed with the kind of gridlock it aimed to avert. But set the tolls too high, and the road won’t get used enough. 

He said it’s true that this kind of new access road can lead to denser housing development in the surrounding area — but the road will need to be tolled carefully to account for that increased demand. 

And the proceeds from those tolls, he said, should ideally go toward new clean transportation alternatives — such as funding additional transit service or safe walking and biking infrastructure around the new toll road, helping to finance subsidized affordable housing in transit-served areas, or allocating revenues to surrounding towns that make “supportive land-use changes” to lean into transit and decrease driving. 

Maine has indicated that it expects to use tolls from the Gorham Connector primarily, or at least in part, to pay for the road itself and avoid passing costs to other taxpayers.

But Accuardi said alternative strategies should see more investment than road expansions in the coming years if states like Maine want to aggressively cut emissions. 

He said on average, across the country, states spend a quarter of their federal transportation funding on “expanding roads or adding new highway capacity.” 

“That’s more money than states tend to spend on public transit infrastructure, and that really needs to be flipped,” he said. “We need to see states really …  ramping down their investments in new highway capacity. Because, again, we know it doesn’t work.”

Climate and clean transportation advocates are calling into question a claim by Maine officials that a new toll road proposed outside Portland will reduce carbon emissions by alleviating gridlock. 

It’s a common argument made in favor of highway expansions nationwide, said Benito Pérez, the policy director of the nonprofit Transportation for America. But it relies on a narrow view of data that, in context, tends to show these projects are more likely to increase planet-warming emissions, he said. 

“They’re looking at it from one dimension,” said Pérez, a former transportation planner and engineer. “This is a multi-dimensional issue when it comes to emissions reduction, and it’s not going to work.”  

Maine’s proposed Gorham Connector project has met stiff public opposition in its rollout over recent months. The toll road aims to offer a more direct route from Portland’s growing suburbs into the city, bypassing local roads that officials say weren’t designed to accommodate increasing commuter traffic.

The project has been contemplated since the late 1980s. Its latest iteration builds on a 2012 study that recommended three main ways to improve connectivity between Portland and points west: new approaches to land use and development, expanded bus and passenger rail access, and various road upgrades and expansions, including the new four-lane, roughly five-mile bypass the state is now proposing.  

The Maine Turnpike Authority took more than three hours of comments at its first public input session on the project in March. On July 18, the MTA said it would delay further public meetings on the project and extend its permitting timeline due to a “high level of public interest and concern.” 

In response to questions for this story, MTA spokesperson Erin Courtney emphasized the importance of a multi-pronged approach in achieving the Gorham Connector’s projected climate benefits. 

“Coupled with targeted land use and transit initiatives, we aim to create a more efficient and sustainable transportation system that addresses both congestion and environmental impacts,” she said.

Benefits are ‘negligible at best’

The emissions impact of smoother traffic on the proposed toll road has been one of the MTA’s core arguments in favor of the project. The agency says on the the website for the Connector that it “will ease traffic flow, decreasing the number of idling vehicles, conserving fuel, and reducing exhaust pollutants in alignment with Maine’s Climate Action Plan.” 

But even in isolation, this emissions benefit is typically “negligible at best,” said Pérez. Despite ongoing improvements in vehicles’ fuel efficiencies and even electrification, he said, studies show that more use of expanded roads tends to outweigh this benefit. 

Pérez pointed to examples in the Washington, D.C. area, Salt Lake City and elsewhere where highway expansions that aimed to reduce gridlock instead led to more traffic and further need for expansions years later — a paradox known as “induced demand.” 

A 2015 paper from the University of California-Davis explains this phenomenon: “Adding capacity decreases travel time, in effect lowering the ‘price’ of driving; and when prices go down, the quantity of driving goes up,” author Susan Handy wrote. New roads, for instance, can encourage more low-density development, which in turn fills those roads with additional drivers. This counteracts the value of highway expansions in alleviating congestion, Handy said, and at least partly offsets the emissions reductions that come along with it. 

Courtney, with the MTA, said “the Gorham Connector’s design and goals suggest a different outcome,” arguing that the project is unique as a limited-access highway without many intersections or entrances. 

“By enhancing traffic efficiency and reducing congestion on local roads, it can offer a balanced approach that considers both transportation needs and environmental impacts,” she said. 

Portland resident Myles Smith, a steering committee member with Mainers for Smart Transportation, a volunteer group opposing the Gorham Connector, isn’t convinced. 

“It’s part of a pattern of showing only the rosiest possible scenarios of how, theoretically, on paper, with a lot of other assumptions going perfectly, it might reduce climate emissions,” he said. “It assumes a lot of other things that they have no control over at the Turnpike Authority, like land-use planning and public transportation.”

New measures of climate impacts 

The 2012 study backing the bypass proposal found that implementing a bevy of suggested road improvements and expansions, including the Connector, would decrease local vehicle hours traveled, or VHT — an analog for congestion, measuring how much time people spend in their cars, Pérez said — by about 10% versus 2035 projections. 

It also said the area’s vehicle miles traveled, or VMT — which measures how much people are driving overall — would increase relative to 2035 projections if the bypass was built, but would decrease in scenarios where only existing roads were improved, or where public transit was the focus. 

“This is why we propose a ‘three-legged stool’ approach,” Courtney said — one that also emphasizes dense development and increased public transit access, so that VMT increases might be offset by other benefits. 

VMT is an increasingly common way to measure the climate benefits of transportation projects, Pérez said. Minnesota and Colorado have adopted new requirements toward goals for reducing their overall VMT, mandating that proposed road expansions either contribute to this decrease, or fund climate mitigation projects otherwise. 

But advocates said VMT and VHT alone are not enough to measure the overall climate impacts of a project like the Gorham Connector. A more comprehensive analysis, they said, would include the environmental impacts of construction and would account in more detail for the role of the non-road improvements that the MTA is also calling for. 

A need for coordinated solutions

The 2012 study, in its final recommendations, said all three strategies — changes to roads, transit and development patterns — would need to “work together to provide the desired results” for improving connectivity and reducing traffic impacts in the Portland area. For example, more dense development and less congestion will make new transit approaches more viable, Courtney said. 

The Turnpike Authority has little direct control over those kinds of reforms, but says on its website that it expects “other regional studies” in those areas to be part of the Gorham Connector planning process. 

“The Gorham Connector project, combined with additional initiatives being considered by the MTA and Maine (Department of Transportation) — such as additional park-and-ride facilities, electric vehicle charging stations, and enhanced transit opportunities — will collectively contribute to reduced greenhouse gas emissions compared to a ‘do nothing’ scenario,” Courtney said. 

Smith said these other efforts are moving more slowly and with less state support than the Connector has received, putting these parallel solutions out of step with each other. 

Maine is facing a lawsuit from youth climate activists over regulators’ decision earlier this year not to adopt California’s Advanced Clean Cars II rule, which would have ramped up requirements for electric and plug-in hybrid vehicle sales through model year 2032. 

The state is still a long way off from the EV goals set in its 2020 climate action plan, which also aims to reduce light-duty vehicle miles traveled 10% by next year and 20% by 2030. 

Advocates applauded a new emphasis on transit, biking, walking and other alternative strategies to achieve those VMT goals in the recommendations from a state climate council working group for a forthcoming update of the climate plan, due out in December. 

It’s an example of slow progress toward more holistic approaches to transportation and climate planning, which, Pérez said, must extend to technical details like the traffic models that underlie projects like the Gorham Connector in order to succeed. 

“Those models need to think about what they’re measuring — what matters most,” he said. “The mindset is, ‘we’re designing for vehicles,’ and that’s what they’re measuring for, not measuring for the movement of people.”

Ron Huber rifled through a thick folder full of decades of state environmental records outside a community hall in the tiny coastal Maine town of Searsport. For the longtime local conservation activist, the scene inside was a familiar one: dozens of neighbors, workers and environmentalists mingled over pizza and coffee, discussing the merits of a proposed industrial project that has potential to transform the local economy, but at the expense of a locally beloved natural area.

“We’ve seen these things rise and fall many times,” Huber said outside the event late this past spring. Conservationists have celebrated over the decades as plans for a coal plant and a liquefied natural gas terminal on Sears Island came and went without success. 

This latest proposal presents a new kind of conflict. Rather than pitting townspeople against a corporate polluter, this development would support clean energy and be integral to the state’s plan for cutting climate emissions.

In May, the state applied for a $456 million federal grant to build a specially designed port on about 100 acres of Sears Island to support Maine’s nascent floating offshore wind industry. About two-thirds of the 941 acre island is in permanent conservation, and the state retains an easement on the rest, which has been reserved for a potential port for years. 

“We’re not optimistic that this one’s going to die under its own weight,” Huber said, noting that the offshore wind port has far more popular support than previous development proposals. 

Visits to recent community events like this one show that, unlike the polarized fights over clean energy projects in other parts of the country, Maine’s wind port is creating more personal divides — challenging residents’ values around climate change, conservation and economic factors. It previews what could be coming as wind grows in the Northeast. 

Conflicting values

“My question is really about why we’re not actually all on the same team,” said Belfast, Maine, resident Julianne Dow inside the community hall, during a question-and-answer period with New England labor organizers. “I’m very pro-union, I’m pro-offshore wind and pro having it here, and for the economic benefits for the region. But I’m also very pro maintaining Sears Island as a precious Midcoast resource.” 

Dow and activists like Huber want the port built instead at a Sprague Energy-owned oil and logistics terminal across the water known as Mack Point. It was considered as an alternative in lengthy public processes in recent years, and Sprague and opponents of the Sears Island proposal have continued to urge reconsideration for it so far this summer. 

Offshore wind has taken some big steps forward in Maine this year. Federal regulators approved a state research array of floating turbines, which generate power in deep waters far offshore, and are nearing leasing for commercial projects. A new state law calls for Maine to procure three gigawatts of offshore wind by 2040, using union-standard labor to build the projects and a floating wind-focused port.

Formal environmental assessments and site analyses are still pending. But state port authority director Matthew Burns wrote in June that Mack Point’s “physical and logistical constraints, need for significant dredging, and increased costs to taxpayers for land leasing and port construction would result in an expensive and inferior port for Maine compared to a versatile, purpose-built port on Sears Island.”

Still, opponents worry that wetlands and forests on Sears Island could be disrupted by port construction, even if most of the surrounding ecosystem remains intact. 

“Because we have to sacrifice something, let’s sacrifice something irreplaceable, instead of cleaning up a dirty old existing port?” Huber said outside the event. “That’s just ridiculous.” 

Asked if he saw wind as a climate solution more broadly, Huber began to express doubts about how turbine arrays would affect the ocean ecosystem. Fellow opponent Lou MacGregor of Belfast cut in. 

“Right now, what we’re focusing on is protecting Sears Island,” MacGregor said. “We can get to whether we support offshore wind or not after we protect Sears Island.” 

‘Skills that pay the bills’

Scott Cuddy, who until recently was policy director of the Maine Labor Climate Council, emphasized at the recent event that his group is agnostic about the port’s location, focusing instead on the benefits it could bring. Under Maine’s wind procurement law, he said, the port’s labor standards will be the same wherever it ends up. 

“We desperately want to see this happen, because we need to fight climate change, and we need to do it with good jobs,” Cuddy said. 

Cuddy and other labor organizers said state studies indicate that the port project and new wind farms could bring thousands of jobs to coastal Maine towns like Searsport. Local leaders said it could be a boost for shrinking school populations, attracting families to stay in the town long-term. 

“I think there’s been a mindset for a long time among kids, especially in rural Maine, like this was the thing I always heard — ‘You got to leave the state if you want to get a good job,'” said Sam Boss, the director of apprenticeships, workforce and equity for the Maine AFL-CIO. “We’ve got to find ways to keep our people here. And if there’s good opportunities, people will stay for them.”

Boss, Cuddy and others answered locals’ questions about plans for training programs for young people to enter the trades, and the family-sustaining wages and benefits promised by the growing wind industry — both in short-term construction positions and into the future.

“These are the skills that pay the bills, and they’re skills that don’t go away. The work might change — you know, we went from nuclear power plants, to now we’re doing offshore wind power development. But the skills are transferable,” said Nicki Kent, a union electrician who came to talk about her experience working on offshore wind in Rhode Island. “We’ve just got to get screwdrivers and wrenches into kids’ hands.”

Belfast resident Daniel Cowan was taking diligent notes on the back of an envelope while his teenage sons listened from the audience. A Navy veteran now pursuing a degree through the GI Bill, Cowan said he was curious about the possibility of wind industry jobs that could help him and his kids stay in Maine. 

Cowan empathized with attendees who were opposed to building the port on Sears Island, but said he thought the project’s benefits sounded like they would outweigh the costs.

“You’re going to destroy something no matter what you do. I love Sears Island, I think it’s great, I love walking my dogs out there. But I don’t think that’s going to change,” he said. “The world is coming to an end one way or another, and how fast we get there makes a difference.” 

Support from anti-wind groups

The island itself is connected to the mainland by a long causeway, bisected at its start by rail lines that snake around the coastline toward nearby Mack Point. The causeway juts out into Penobscot Bay, and Sears Island opens up at its end, an oval of land covered in trees and flanked by sandy, seaweedy shores. 

On a Saturday morning not long before the Searsport labor dinner, a large group of birders gathered at the gate where the causeway’s pavement continues into the forest. They had come to scout for the tiny, colorful songbirds that rest on the island each year amid long migrations between Canada and the tropics. 

Near the edge of the woods, someone had spray-painted the asphalt road with “Wassumkeag,” the indigenous Wabanaki name for the island. Hand-lettered signs with the web address for the advocacy group Alliance for Sears Island read, “Wind power = Good? On Sears Island = Bad!” 

The state does not plan to site wind turbines on Sears Island itself. Workers at the proposed port would help build and assemble towers and blades in pieces, towing them far out to sea for final assembly. 

Still, anti-wind groups have seized on the proposed project. Lobstermen affiliated with the New England Fishermen’s Stewardship Association (NEFSA), a Maine-based advocacy group founded in 2023 that focuses partly on opposing offshore wind, spoke out against the port at the recent jobs event. 

“My concern is only that in trying to affect climate change, that we’re going to cause more damage to the environment than climate change is already causing,” said NEFSA officer Dustin Delano, a commercial fisherman from Friendship, Maine. 

NEFSA has since posted signs where the island causeway intersects with the heavily trafficked Route 1 that read “Keep Sears Island wild.” Similar signs showing a crossed-out wind turbine bore the name of Rhode Island-based Green Oceans. Since its founding in 2022, it has focused mostly on opposing Revolution Wind, currently under construction in waters between Rhode Island and Connecticut. 

Many who joined the recent birding trip seemed unaware that Maine’s plans for Sears Island did not involve actually erecting turbines there or close to shore. Others expressed doubts about wind generally. Some did not want to discuss the issue at all, focusing instead on peering through binoculars at the Northern parula, black-throated green warbler or hermit thrush chirping in the trees along the road. 

A few people mentioned concerns that wind projects could harm whales. Scientists have found no evidence to support this claim, which has been linked to fossil fuel-funded disinformation campaigns. Green Oceans’ campaigns in Rhode Island have mimicked the delay and disinformation strategies of climate denialist groups like the Texas Public Policy Foundation, according to Brown University research. 

Climate impacts close to home

The threat of climate change to ecosystems like Sears Island’s, meanwhile, is very real. The Gulf of Maine is one of the fastest-warming water bodies in the world, swelling sea levels, threatening the lobster fishery and leading to more frequent, destructive storms. Maine saw a state-record four federal disaster declarations in 2023 and has received two more already this year. 

The warming trend may affect the migratory birds that draw crowds to Sears Island each year. Warming temperatures are reshaping the length and timing of Maine’s seasons, which, combined with declines in insect populations driven by agriculture and other factors, could threaten the birds’ success, studies show. 

“If you look at decades and decades of patterns, you’ll see that birds are arriving one to two weeks earlier,” said William Broussard, a Midcoast Audubon board member who led the recent Sears Island trip. “If they get here early, they might not have the insects that they depend on to be out, because maybe the trees aren’t leafing out… and that can be really tough.” 

Midcoast Audubon hasn’t taken a position on the wind port issue. It’s a chapter of Maine Audubon, which separately supports the project but is not advocating for one site over the other. Maine Audubon is likewise independent from the National Audubon Society, which advocates for “responsibly sited renewable energy,” including wind, as a climate solution.

‘A terrible dilemma’

Marge Stickler, a birder from Belfast, said she wished the port would be built at Mack Point instead. “I have mixed feelings about what they’re doing here,” she said. “I love coming here… it’s a special place.” 

She had read an opinion piece earlier this year by activist Bill McKibben, founder of the climate groups 350 and Third Act, that urged Mainers to support the wind port even on Sears Island. McKibben wrote for Mother Jones last year that solving climate change will require a new “yes in my backyard” mindset. 

“McKibben wrote that you have to look at the climate as a whole, and this may be a good thing to have here,” Stickler said. “I’m not sure — why did he write that for Maine, he lives in Vermont, but… he said it’s better to have it and it’s better to have it here, maybe.” 

Dave Andrews, a retired engineer from South Bristol, Maine, struck a different tone as he trailed after the other birders. He’d worked on Superfund cleanups and brownfield solar projects in his career, and said he’d often heard “not in my backyard” sentiments from neighbors who were worried about viewshed impacts or a change in a place’s character. 

“If it’s a Walmart shopping center, I guess you have a valid statement,” he said. “But when it comes to something like this, this is a different balance.” 

Andrews called the port’s siting a “terrible dilemma.” But he felt swayed by the urgency of climate change and the fact that the project would leave much of Sears Island intact. As permitting and siting progress in the coming months, he said he hoped others who love the island would be able to accept the sacrifice.

“I don’t think there is a choice,” he said.

A new analysis says Vermont is not on track to meet its 2025 target for reducing greenhouse gas emissions, with declines in thermal fossil fuel use driven mostly — though not entirely — by warming winters. 

The study, released last month by the Vermont nonprofit Energy Action Network, also shows signs of progress: Though rising temperatures are still the main driver of lower heating fuel sales, weatherization and electric heat pump adoption are starting to have a greater impact.

“Vermont’s efforts… are, ironically, being aided by the very global heating that we are working to do our part to help minimize,” the study says. “Relying on warmer winters to reduce emissions from fossil heating fuel use is not a sustainable strategy. … What [the warming trend] means for temperatures — and therefore fuel use — in any given year is still subject to variation and unpredictability.” 

Like most other New England states, Vermont relies heavily on heating oil and, to a lesser degree, propane and utility gas, to heat buildings. This makes the building sector a close second to transportation in terms of the biggest contributors to planet-warming emissions in Vermont and many of its neighbors. 

Vermont’s statutory climate targets, adopted in 2020, aim to cut these emissions by 26% below 2005 levels by next year, with higher targets in the coming decades.

“It’s technically possible” that Vermont will meet its thermal emissions goal for next year, but “at this point, primarily dependent on how warm or cold the fall and early winter heating season is at the end of 2024,” EAN executive director Jared Duval said. The transportation sector would need to see a nearly unprecedented one-year decline.

On the whole, EAN says it’s “exceedingly unlikely” that Vermont will meet its 2025 goal. 

Warmer winters ‘not the whole story’

EAN found that heat pump adoption and weatherization are not happening fast enough, and what’s more, the current trend sets Vermont up for a Pyrrhic victory at best: Rising temperatures in the upcoming heating season would have to be at least as pronounced as in last year’s record-warm winter in order to reduce fuel use enough to meet the 2025 target for the thermal sector. 

Either way, warming alone won’t get Vermont to its 2030 target of a 40% drop in emissions over 1990 levels, Duval said. The state wants to end up at an 80% reduction by 2050. 

“The only durable way to reduce emissions in line with our science-based commitments is to increase the scale and pace of non-fossil fuel heating solutions and transportation solutions,” he said.

The EAN study found that fuel sales tend to decline alongside heating degree days: a measurement of days when it’s cold enough to kick on the heat. Vermont is seeing fewer of these days overall as temperatures warm. 

“The reduction in fossil heating fuel sales as winters have been warming is not surprising,” Duval said. “Historically, fossil heating fuel use and therefore greenhouse gas emissions have largely tracked with heating demand, with warmer winters corresponding with less fossil fuel use and colder winters with more fossil fuel use. The good news is that’s not the whole story.”

In recent years, he said, fuel sales have begun to “decouple” from the warming trend to which they were once more closely linked. From 2018 to 2023, EAN found that Vermont fuel sales declined 12% while heating degree days only declined 8%. 

“Fossil heating fuel sales are declining even more than you would expect just from warmer winters alone,” Duval said. “And that’s because many non-fossil fuel heating solutions are being adopted.” 

Upgrades needed to accelerate progress

From 2018 to 2022, EAN found, Vermont saw a 34% increase in weatherization projects and more than 50,000 more cold-climate heat pumps installed in homes and businesses, with a 3.3% increase in the number of homes that said they use electricity as their primary heating fuel. 

The upshot: The number of cold days explains 50% of Vermont’s declining fuel use from 2018 to 2023, while heat pump growth explains as much as 28% and other efficient upgrades explain a further 15%. The remaining 7% of the decline couldn’t easily be broken down and could partly be from people shifting to wood heat during periods of high fuel prices, Duval said.

“In order to achieve thermal sector emissions reduction targets without relying primarily on an abnormal amount of winter warming, significantly more displacement and/or replacement of fossil heating fuel… will be necessary,” the study says. Upgrades like heat pumps will lead to more sustainable emissions cuts, it says, “no matter what the weather-dependent heating needs in Vermont will be going forward.” 

EAN is nonpartisan and doesn’t take policy positions, but research analyst Lena Stier said this data suggests that expanding Vermont’s energy workforce and tackling heat pumps and weatherization in tandem would spur faster progress on emissions cuts, while keeping costs low.

EAN based its estimates of fuel use and emissions impacts from heat pumps on the official assumptions of a state-approved technical manual, which Duval said may be overly optimistic. But Stier said the reality could differ.

“We’ve heard anecdotally that a lot of people who have installed heat pumps in their homes… are kind of primarily using them for cooling in the summer,” she said. “So our kind of assumption is that, in reality, it would be a smaller share of that (fossil fuel use) reduction coming from heat pumps.” 

While fuel use declined overall in the study period, he said this came mostly from people using less heating oil specifically — propane sales actually increased in the same period.

Duval noted that propane is cheaper than oil on paper, but actually costs more to use because it generates heat less efficiently than oil does. 

“Once you look at that, then heat pumps become that much more attractive,” he said.
