Department of Ecology, State of Washington

The purpose of Washington Cap-and-Invest Rulemaking is to make improvements to the implementation of the Cap-and-Invest Program, facilitate the linkage of Washington’s carbon market with the California-Québec carbon market, as well as make other necessary updates. Ecology is considering amendments to the Climate Commitment Act Program rule (Chapter 173-446 WAC) and the Reporting of Emissions of Greenhouse Gases rule (Chapter 173-441 WAC).

Draft Rule Language Now Available
An updated draft of the rule language, specific to electricity imports and centralized electricity markets (WAC 173-441-124), is now posted on the Cap-and-Invest Program Updates and Linkage rulemaking webpage and available for your review.
