Maine

Maine was the first state to set greenhouse gas reduction targets in 2003, and emissions decreased by 74% between 1990 and 2021. The transportation sector is driving the state’s emissions, primarily due to the geographically spread-out population. Long winters place the residential sector’s emissions closely behind transportation, as buildings require significant heating in the state’s colder months.
