Climate Change

The Rhode Island Department of Environmental Management supports a wide range of efforts to address climate issues in the state. Climate change is a serious threat for Rhode Island because of its potential impacts on coastal areas, drinking water, energy supplies, the economy, and public health. Climate change mitigation is addressed while meeting the Department’s responsibilities in areas of reducing greenhouse gas emissions.

Official Rhode Island Greenhouse Gas Emissions Inventory

RIDEM maintains an inventory of greenhouse gas (GHG) emissions in Rhode Island in accordance with the state’s 2021 Act on Climate. The GHG emissions inventory is important for assessing progress related to reducing GHG emissions in our state. Additionally, an accurate GHG emissions inventory can inform policy writers to meet our climate goals.

Mobile Sources

RIDEM works to reduce criteria and GHG emissions from motor vehicles through a variety of regulatory programs, policy initiatives, and grant programs. This includes, but is not limited to, upholding Rhode Island’s regulations as a California Section 177 state.

Regional Greenhouse Gas Initiative (RGGI)

The Regional Greenhouse Gas Initiative (RGGI) is the first mandatory market-based program in the United States to reduce greenhouse gas emissions. RGGI is a cooperative effort among Northeastern and mid-Atlantic states to cap and reduce CO2 emissions from large fossil-fueled power plants. The regional initiative has been successful in reducing GHG in the participating states, reducing CO2 emissions from the power sector by more than 50% by 2018.

Regional Collaboration on Climate Change Mitigation

Climate change is a global issue that requires solutions on a regional and local scale. In addition to responding at the state level, Rhode Island collaborates with other states to address climate change’s unique challenges in the Northeastern U.S. Regional collaboration on GHG emission reduction and mobile source electrification will greatly amplify the impact of such adoptions. Benefits that are created locally will ultimately be seen on a regional, national, and global scale.
