What We Do

We work with and support Seattle city council members and the Seattle Office of Sustainability and Environment (OSE) to implement a comprehensive, robust, equitable, and measurable climate action plan (CAP) to reach the greenhouse gas (GHG) reduction targets set by the King County-Cities Climate Collaboration. This includes advocating for issues such as better public transit, electrified transportation, and a path to transitioning building heating from fossil fuels to electricity generated from renewable energy sources. 

PCA-Seattle is a member of the countywide PCA Coalition, whose mission is to help local governments develop and implement comprehensive CAPs to reach the GHG reduction targets set by the King County-Cities Climate Collaboration (K4C). So, we also meet with the four (out of nine) King County council members who represent areas of Seattle.

The Port of Seattle, which includes the airport and seaport, is a separate jurisdiction whose five commissioners are elected by all the voters of King County. Therefore, the Port is a concern for the countywide PCA Coalition. Several PCA-Seattle members are concerned about the Port’s GHG emissions and are working to oppose the proposed new cruise ship terminal in Pioneer Square, which would not only increase particulate pollution in Seattle and environs, but would also increase GHG emissions from air travel and ocean travel, as well as stress our fragile remaining orca population.


PCA-Seattle is committed to advocating for comprehensive climate action planning for our city. As part of this, we periodically send letters to local elected officials, advocating for elements of climate action planning that we feel are important. Here are letters we have sent on various issues.
