Limiting carbon pollution through the Washington Clean Air Rule

See the recording of the June 23 webinar about the Clean Air Rule.

Capping carbon pollution will help slow climate change and limit the projected effects on our state's coastal communities, agricultural industries, and drinking water supplies.

Climate change is the most significant environmental issue of our lifetime, and we need to protect what we have today for future generations. So, we've been focusing our efforts on Washington's first-ever rule to cap and reduce carbon pollution.

We released a new draft of the Clean Air Rule on June 1. We are now accepting comments on the rule.

We're moving ahead quickly and expect to adopt the rule in late summer.
