Climate Change

Climate change is a serious threat and one of the most significant challenges of the 21st century. Scientific evidence shows that greenhouse gas emissions have accelerated global warming and that action to address climate change must occur. We seek to contribute actively and decisively to a low-carbon and sustainable future, delivering clean, low emission energy, minimizing the environmental impact of our activities and supporting and promoting actions that address climate change. Such efforts must be compatible with social and economic growth.

Taking Action

Maine was the first state in the nation to set greenhouse goals (2003). Maine has also set oil usage reduction targets (2011). Maine law now requires the state to reduce emissions 45% below 1990 levels by 2030 and 80% by 2050.

According to Maine’s 8th Biennial Report1 on progress toward Greenhouse Gas Reduction Goals, Maine’s electricity sector reduced emissions by 50% between 1990 and 2017, to the point where electric power generation accounted for only 7% of CO2 emissions from fossil fuel combustion in 2017. CMP has continued to provide safe and reliable delivery of this cleaner power, integrating onto the network newer wind and solar generation resources in combination with maintaining delivery of Maine’s traditional hydropower and biomass renewable resources.

Transportation accounts for over 50% of Maine’s CO2 emissions from fossil fuel combustion. We promote actions that seek to reduce this carbon pollution from the transportation sector; see our activities to encourage the adoption of electric vehicles.

Climate change is a national and global challenge; see what AVANGRID and Iberdrola are doing to fight climate change.
