Driving common sense climate policy for a stronger, cleaner economy in Washington

Clean & Prosperous Washington engages in advocacy, lobbying, and public policy work to support effective, market-based climate policies that benefit the economy, communities, and the environment. As the 501(c)(4) advocacy arm of Clean & Prosperous, we focus on advancing and defending state-level policies that reduce emissions, drive innovation, and create good-paying jobs across Washington state.

Our core focus is the state’s nation-leading cap-and-invest system. Carbon markets like cap-and-invest cover more than 28% of global greenhouse gas emissions, and are the most effective, proven model for reducing pollution while growing the economy. Whether in Olympia or across the world, we’re working to ensure Washington continues to lead the way with our ambitious, proven emissions cap.

The Climate Commitment Act

A leading model
worth protecting

The Climate Commitment Act is one of the most ambitious and effective pollution reduction policies in the world and a cornerstone of Washington’s clean energy future. It sets a declining cap on carbon emissions from the state’s largest emitters and reinvests revenues into communities through clean transportation, energy efficiency, wildfire resilience, and more.

Clean & Prosperous supported the successful “No on 2117” campaign in 2024, helping voters understand what was at stake in the effort to repeal the CCA. Working in coalition with community and business partners, we mobilized support to protect this landmark law—and the billions of dollars in healthy air and clean transportation investments it enables.
