Incorporated in Rockport, Maine as Environment Northeast

One of the first organizations created in the United States to focus on climate solutions at the state and regional levels, Acadia Center has had significant impact in the northeast region with application to other parts of the country and Canada and overseas.


Connecticut Energy Efficiency Advisory Board

Created Connecticut stakeholder board consisting of consumer, environmental, business, low-income and state agency representatives, to decide on budgets, savings goals and program design. This board provides a fact-based process that often reached consensus among previously fractious parties.


Protecting Our Biosphere Report Influenced the Climate Change Roadmap for Connecticut

This report showed how the United States could start on the path to low emissions future that offered economic gains and workforce development for less than $5 billion.


Climate Change Roadmap for Connecticut

Acadia Center conceived and created the first comprehensive climate roadmap at the state level produced by a non-profit policy and advocacy organization. In Connecticut, our work helped pass the state’s first climate law in 2004, setting the first state goal for reducing emissions in 2050 by 80%.


“Green Power” Purchasing Campaign

Our staff led the development of the first Renewable Portfolio Standard in most states in our region and continued to influence the expansion of these mandates. Over the past 20 years, due to these and the efforts of many, the power grid in New England has seen its reliance on dirty fuels like coal and oil drop to virtually zero while renewables, energy efficiency have grown.


ClimateVision 2020

Acadia Center assessed the progress of states in meeting targets established in the growth of state climate laws being adopted in 2004 and after.


Climate Change Roadmap for New England and Eastern Canada

Acadia Center authored the first multi-state climate roadmap in North America.


All Cost-Effective Energy Efficiency (ACE) Policy

Our All-Cost-Effective Energy Efficiency (ACE) policy was adopted as official state policy in Massachusetts, Connecticut, Rhode Island and Maine starting in 2006 through 2009. As a result, these states saw dramatic results with significant energy efficiency offerings to their residents:

  • Massachusetts’ energy efficiency program expanded 4-fold – from $125 million year to $540 million/year.
  • Rhode Island expanded from $16 million to over $100 million.
  • Connecticut more than doubled its energy efficiency program.
  • Efficiency Maine began offering the state’s first real energy efficiency programs to all customers.
  • The New Hampshire Board drew from the examples of our other boards


Received the ACEEE Champion of Efficiency Award

These awards recognize leadership and accomplishment in the energy efficiency field. Winners are selected based on demonstrated excellence in program implementation, research and development, energy policy, or private sector initiatives. Acadia Center, then Environment Northeast, won for shepherding policies that engage stakeholders, substantially increase energy efficiency investments, and institutionalize support for energy efficiency throughout New England


Efficiency Maine Trust

The Efficiency Maine Trust (the Trust) is the administrator for programs to improve the efficiency of energy use and reduce greenhouse gases in Maine. The Trust serves all sectors and all regions of the state. Its suite of programs provides consumer information, rebates and loans for the purchase of high-efficiency, clean energy products.


Regional Greenhouse Gas Initiative

Acadia Center has been a leader in shaping and promoting the design of the Regional Greenhouse Gas Initiative (RGGI), the nation’s first multi-state agreement to limit emissions from power plants. RGGI has created over $4 billion in revenue for states to reinvest in clean energy, energy efficiency, consumer support to shift off fossil fuels and many other beneficial uses.


ISO-NE Grid Modernization

Acadia Center played a key leadership role in advocating that ISO-New England incorporate the benefits of energy efficiency when planning power needs. In 2012, ISO-NE folded into their 10-year forecast of power on the power grid – the first regional grid operator to do so in the country – leading to the cancellation of over $400 million in planned upgrades to the transmission system that were no longer needed because of the benefits of efficiency. The region now relies on 12% of its power needs from the energy savings produced by these nationally leading programs – the highest in the United States, saving consumers billions of dollars in spending.



Community|EnergyVision is a comprehensive framework that outlines a pathway for communities to take control of the energy system and modernize the way it is planned and managed. The illustrated publication details the full range of relevant issues surrounding Community Energy and provides examples of successful Community Energy systems emerging in the U.S. and abroad.
