Clean Air Rule
Washington’s water supply, air quality, and infrastructure are at risk because of climate change. Ecology adopted a rule under our state’s Clean Air Act to reduce carbon pollution to do our part to help slow climate change. The Clean Air Rule regulates the businesses who are responsible for about two thirds of carbon pollution in Washington, such as transportation, refining, and manufacturing.
Who is covered under the Clean Air Rule?
In 2017 organizations that are responsible for 100,000 metric tons of carbon pollution annually are required to cap and gradually reduce their emissions. Every three years, the threshold is lowered by 5,000 metric tons and more emitters are brought into the program. By 2035 the threshold will reach 70,000 metric tons where it will remain.
Businesses categorized as energy-intensive, trade-exposed industries and fuel importers begin participating in the program in 2020.
The types of organizations covered by the rule include:
