Considering A Regional Clean Fuel Standard

Source: Puget Sound Clean Air Agency.

Transportation is the primary source of climate pollution in the Puget Sound region – over 40 percent of the Puget Sound region’s greenhouse gas (GHG) pollution.

In 2017, the Puget Sound Clean Air Agency’s Board of Directors adopted a science-based target to reduce greenhouse gas pollution by 50 percent below 1990 levels by 2030, and is considering adopting a regional Clean Fuel Standard to help meet that target. 

A Clean Fuel Standard would reduce greenhouse gas pollution from transportation to address climate change and protect human health. The standard would apply to transportation fuels supplied or sold in the Puget Sound Clean Air Agency’s jurisdiction — King, Kitsap, Pierce, and Snohomish counties. 

Rulemaking Process

The Agency has drafted a rule for the Agency’s Board of Directors to consider for action in early 2020.


  • October 9, 2019: Release of a draft Clean Fuel Standard rule, starting a 90-day public comment period.
  • December 19, 2019: Public hearing and Board of Directors meeting on the draft rule at the Washington State Convention Center.
  • January 6, 2020: The public comment period closes. 
  • Early 2020: The Agency will consider all comments received during the public comment period. The Agency’s Board of Directors will then consider action on a potential final rule no sooner than the Board’s meeting on February 27, 2020.
