Connecticut

Connecticut established the nation’s first green bank in 2011 and has since leveraged nearly $3 billion in clean energy investments into the state’s economy. From 2001-2022, the state reduced net emissions by 9%, around a quarter of the emissions reductions required by 2030. Connecticut has no fossil fuel reserves but more than half of the state’s generated electricity is sourced from natural gas, with another 40% from nuclear.

This map shows the occurrence of climate policies passed at the state-level. Higher numbers represent more climate policies enacted.

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  • Not Enacted Not enacted policies have not been passed or established in the state or are no longer in effect.

An Environmental Rights Amendment is an amendment to a state constitution guaranteeing the citizens of that state a right to a clean and healthy environment. The right to a clean and healthy environment can help to address climate change and provide a key tool to regulate greenhouse gases and achieve environmental justice goals.

Just transition offices and staff assist workers and communities transitioning away from fossil fuel extraction and use, typically through retraining programs and support with relocation and economic diversification. Offices and staff also coordinate with other state agencies to effectively design policy to achieve a just transition.

State divestment means ending new investment in the fossil fuel industry and phasing out existing fossil fuel investments in public funds, such as state pensions, over time. States can also set greenhouse gas emissions reduction targets for their investment portfolios.

Low NOx Omnibus Rules establish stringent tailpipe emission standards for heavy duty vehicles, updated testing procedures, and technology-neutral compliance mechanisms to reduce nitrous oxide (NOx) pollution. The regulation must be adopted first by California, and other states may adopt the regulation under the federal Clean Air Act.
