Maine has increased renewables energy generation for more than two decades and significantly increased its ambition on climate change in the past couple of years. The vulnerability of the state’s coast to climate change threats has also contributed to the urgency for climate action. Through legislation signed into law by Governor Janet Mills in 2019 Maine targets 80 percent renewables in its electricity sector by 2030, with a goal of 100 percent by 2050. This 2019 legislation also established the Maine Climate Council, a diverse group of stakeholders responsible for releasing a plan every four years (the first was in December 2020) to meet the state’s emissions-reduction targets of 45 percent below 1990 levels by 2030 and 80 percent by 2050. Another initiative, an Executive Order signed by Governor Mills, set a goal of carbon neutrality by 2045. Governor Mill’s push for climate action holds bipartisan support; which bodes well for implementing the state’s climate plan. Maine is a member of the US Climate Alliance and the Regional Greenhouse Gas Initiative (RGGI), a market-based programme to reduce emissions in the power sector.
