From the Governor

You asked us to pay attention to what the United Nations scientists have called a “Code Red for Humanity” and the violent storms across the nation damaging homes, towns, fisheries, wildlife, everything our nation holds dear. So, with renewable energy, weatherization, efficiency, alternative heating sources, and a focus on resiliency, we have put Maine on a path towards carbon neutrality, with a plan to protect our precious farms, shorelands and towns from the ravages of climate change.

Gov. Janet Mills
