Connecticut

Connecticut established the nation’s first green bank in 2011 and has since leveraged more than $2.43 billion of clean energy investments into the state’s economy. From 2001-2021, the state reduced greenhouse gas emissions by 17%. Connecticut has no fossil fuel reserves but more than half of the state’s generated electricity is sourced from natural gas. Connecticut uses less energy per-capita than 46 other states.

Progress by Policy Area

Enacted Enacted policies have been passed or established in a state by a governing body via legislation, executive orders, rules, regulations, and/or other program creation, and remain in effect.
In-progress In progress policies have been established in a state, but final regulations, rules, or plans are pending final approval. This also includes legislation and executive orders that require regulations to be put into effect.
