Hammering out Maine’s Climate Action Plan: Deep Dive into the BIH Working Group Recommendations

Maine’s Climate Action plan is being hammered out this year by the Maine Climate Council, convened by Gov. Janet Mills. The Climate Action Plan will be a roadmap to achieving Maine’s goals of reaching 45% greenhouse gas emissions reductions by 2030, and at least 80% by 2050. This blog takes you on a deep dive into the process of creating recommendations for the Action Plan, particularly for the Buildings, Infrastructure, and Housing Working Group. You can access more of the recommendations here.

In May, despite the coronavirus, the Acadia Center and its partners convened a (virtual) meeting of more than 400 people, including dozens of environmental, labor, and public health organizations, to learn about how the Climate Action Plan will be created. The webinar, titled “The Maine Climate Council: Everything You Need to Know” was hosted by over 30 entities dedicated to reducing carbon pollution and equitably transitioning Maine’s economy to clean, renewable energy. Acadia Center joined its partners to call for action that strengthens the economy, creates well-paying jobs, improves public health, and ensures equitable distribution of investments, benefits, and opportunities. The full webinar can be found at this link.

Speakers at the webinar demanded a Climate Action Plan with concrete legislative and regulatory actions to mitigate and adapt to climate change. Clear implementation timelines and targets are also essential. Acadia Center has been working individually and with its coalition partners to influence policy strategies being developed across seven working groups of the Maine Climate Council. These working groups have been created to tackle the topics of coastal and marine issues; community resilience planning, public health, and emergency management; electricity and utility innovation; natural and working lands; and transportation. The working group members include businesses, legislators, nonprofits and foundations, scientific and academic experts, state and local governments, and youth representatives, each of which provide a different perspective on the issues. In their decision-making process, working group members considered costs and benefits; impacts on low-income, senior, and rural residences; funding and financing mechanisms; and economic and workforce results. During the webinar, Jeff Marks of Acadia Center presented the results of the Buildings, Infrastructure, and Housing (BIH) Working Group.

Why is the buildings and infrastructure sector so important to Maine’s climate goals? In Maine, this sector comprises 39% of total greenhouse gas emissions, with the residential sector the second highest carbon-emitter overall at 19% of the state’s emissions (transportation is first at 54%). Maine also has some of the oldest building stock in the country (56% of Maine homes were built before 1980) and the highest reliance on fossil fuels for heating. Sixty percent of homes still heat with oil, and 19% with natural gas or propane.

The BIH Working Group moved forward strategies that lead to:

Acadia Center outlined six strategies to reduce emissions in buildings, infrastructure, and housing:

1. Improve the design and construction of new buildings through steadily and more stringent building codes, increased compliance and enforcement, and focus on both operational and embodied carbon.
2. Transition to cleaner heating and cooling, especially high-efficiency space and water heat pumps.
3. Enhance the efficiency and resiliency of existing building envelopes, including audits, deep retrofits, and weatherization.
4. Lead by example in publicly funded buildings, including affordable housing, government buildings, and schools.
5. Accelerate the decarbonization of industrial processes, including overcoming limited funding for industrial efficiency, combined heat and power, and microgrids.
6. Modernize and stabilize the electricity grid, including ways to meet new demand in parallel with beneficial electrification, decarbonization, electric vehicles, and authorizing state agencies to consider climate mandates in their regulatory processes and decisions.


The Working Groups submitted their recommendations to the Maine Climate Council in June 2020, with a final Climate Action Plan due in December 2020.

In addition, Acadia Center was part of an open letter calling on the Maine Climate Council to strategically prioritize specific recommendations – read the details here on our website.

Commentary: Maine’s renewable-energy industry gets a double shot in the arm


Major new solar and offshore wind projects help position us as a hub to start, grow and maintain energy businesses.

Maine has incredible natural energy resources that can and should be an engine of its economy. New solar and offshore wind projects help position Maine as a hub to start, grow and maintain energy businesses in a global market. This week, Maine put out the welcome mat and opened the door to being a leader in clean energy.

First, two solar development companies on both sides of the Atlantic joined forces to advance projects to generate 350 megawatts of renewable energy capacity across eight Maine communities. The international partnership between European Union-based BNRG Renewables and Portland’s Dirigo Solar LLC is moving forward with large-scale solar projects to produce enough electricity to power 78,000 homes.

The next day, a $100 million joint venture publicly emerged to develop floating offshore wind technology off the coast of Maine, potentially bringing tremendous economic, energy and environmental benefits to Maine’s coastal regions and the state. The public-private partnership includes Maine’s flagship educational institution, the University of Maine, and New England Aqua Ventus LLC, a collaboration between technology giant Mitsubishi Corp. and the second largest offshore wind company in the world, RWE Renewables. According to a joint statement by Sens. Susan Collins and Angus King and Reps. Chellie Pingree and Jared Golden: “Maine’s offshore wind resource potential is 36 times greater than the state’s electricity demand, making this project so significant for Maine’s clean energy future.”

The Maine Climate Council: What You Need to Know Webinar

May 27, 2020, 12:00 – 1:30 p.m.

Despite the public health crisis, the Maine Climate Council has continued its important work developing a climate action plan for Maine. The Climate Council’s six working groups have been meeting virtually over the last few months to develop their recommendations to reduce Maine’s greenhouse gas emissions at least 80% by 2050, a target set it Maine law.

Please join Acadia Center and our partners for a Zoom webinar to hear from Maine Climate Council working group members about strategies they are developing to help Maine meet its climate goals and how you can take action. In addition to Working Group updates on forests, power and utilities, transportation, Acadia Center’s Jeff Marks will be presenting on the strategies being considered by the Buildings, Infrastructure, and Housing Working Group.
