Massachusetts Legislation & Strategy

Regional & National Cooperation

  • Regional Greenhouse Gas Initiative (RGGI Inc.)
    Cooperative effort by Northeast and Mid-Atlantic states to reduce emissions of carbon dioxide.
  • Massachusetts & the Regional Greenhouse Gas Initiative (RGGI)

    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.

  • The Climate Registry
    Collaboration among North American states, provinces, territories and native sovereign nations that sets standards for calculating, verifying and publicly reporting greenhouse gas emissions.
  • The Climate Registry (TCR)
    About TCR and participating states, provinces and tribes.

Energy Programs & Partnerships

  • Climate Change Laws & Regulations
    Learn about the Global Warming Solutions Act (GWSA), greenhouse gas (GHG) credits and trading, the Massachusetts GHG Emissions Reporting Program, and other state initiatives.
  • Renewable Energy Portfolio Standard (RPS) & Alternative Energy Portfolio Standard Programs (APS)
    Massachusetts' Renewable Energy Portfolio Standard (RPS) was one of the first programs in the nation that required a certain percentage of the state's electricity to come from renewable energy. The Alternative Energy Portfolio Standard (APS) was established to complement the RPS Program, providing requirements and incentives for alternative electricity technologies.
