Washington State must limit greenhouse gas (GHG) emissions to achieve the following reductions:

  • By 2020, reduce overall GHG emissions in the state to 1990 levels;
  • By 2035, reduce overall GHG emissions in the state to 25% below 1990 levels; and
  • By 2050, reduce overall emissions to 50% below 1990 levels or 70% below the state's expected emissions that year.
Every other year, the Washington Departments of Ecology and Commerce must report to the governor and legislature on the total GHG emissions in the state for the previous two years. For more information, see the Washington Department of Ecology Climate Change and the Environment website.
