Learn about the progress Massachusetts is making toward its clean energy and climate protection goals.
In January 2007, Massachusetts joined the Regional Greenhouse Gas Initiative (RGGI), a cooperative effort by Northeast and Mid-Atlantic states to reduce emissions of carbon dioxide, a greenhouse gas that contributes to global climate change. To address this important environmental issue, RGGI and its member states have developed a regional strategy for controlling emissions, including a market-based, multi-state cap-and-trade program that requires electric power generators to reduce their emissions of carbon dioxide.
Consistent with the Clean Energy and Climate Plan, and its requirement that Massachusetts achieve an 80 percent reduction in GHG emissions by 2050, MassDEP intends to implement a Clean Energy Standard (CES).
