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.
Partially Enacted Partially enacted policies have been enacted in the state, but are missing one or more policy components. Dashboard policies cannot be considered partially enacted unless policy components are available.
Not Enacted Not enacted policies have not been passed or established in the state or are no longer in effect.
