Reducing Greenhouse Gas (GHG) Emissions

Washington State is addressing the challenge of climate change by taking responsible and thoughtful actions. The State has developed practical and coordinated set of policies and solutions to meet the greenhouse gas emissions reductions adopted into law in 2008, and to unleash innovation, investment and job creation. Many of these actions are being implemented. 

Clean Power Plan

The U.S. Environmental Protection Agency (EPA) proposed the first ever carbon pollution limits for the nation’s existing power plants in June 2014. EPA’s proposal is called the Clean Power Plan, and was issued under Section 111(d) of the Clean Air Act. Power plants are the largest source of carbon pollution in the U.S., accounting for roughly one-third of all domestic greenhouse gas emissions.

Zero Emission Vehicles (ZEVs)

Nearly half of all greenhouse gas in the state comes from transportation. One of the ways we plan to reduce vehicle pollution is through a new program to promote zero emissions vehicles (or ZEVs) in Washington. ZEVs can play a major role in helping us reduce the amount of greenhouse gas caused by transportation.

Executive Orders

Executive Order 14-04 - On April 29, 2014, Gov. Jay Inslee signed an executive order outlining a series of steps to cut carbon pollution in Washington and advance development and use of clean energy technologies. (Also see the Governor's Carbon Emissions Reduction Taskforce (CERT))

Executive Order 09-05 - On May 21, 2009, Gov. Chris Gregoire directed implementation of state actions to reduce greenhouse gas emissions, increase transportation and fuel-conservation options for Washington residents, and protect our state’s water supplies and vulnerable coastal areas.

SEPA and climate change

The Washington Department of Ecology has prepared a draft working paper for lead agencies for use when evaluating proposals under the State Environmental Policy Act (SEPA) that will result in greenhouse gas (GHG) emissions and/or may be vulnerable to the effects of climate change.

State Agency Climate Leadership

In 2009, the Washington State Legislature approved the State Agency Climate Leadership Act E2SSB 5560, which established greenhouse gas emissions reduction limits for state agencies in law (RCW 70.235.050 and RCW 70.235.060) and directed state agencies to quantify GHG emissions, report on actions taken to reduce GHG emissions, and develop a strategy to meet the GHG reduction targets.
