Limiting carbon pollution through the Washington Clean Air Rule

Earlier this year, we proposed the draft Clean Air Rule, which would cap and reduce carbon pollution in Washington. The rule would help slow climate change and limit the projected effects on our state's coastal communities, agricultural industries, and drinking water supplies.

Based on feedback we received from environmental and industry stakeholders, we later withdrew the draft to allow more time to continue working with stakeholders and to integrate suggestions.

We shared our latest thinking on the rule via a webinar April 27. If you missed the webinar you can watch a recording or review the presentation as a PDF:
