King County - Cities Climate Collaboration

From more intense wildfires and harmful smoke to increased drought and less snowpack in our mountains, we are already experiencing climate change in King County. We have an urgent need to act boldly as a collective to create a healthier, more just, and resilient region. That’s why the King County-Cities Climate Collaboration, or the K4C, exists. We’re a partnership of local governments of all sizes working together to accelerate climate action. We combine our knowledge, resources, and advocacy power to shape policy and programs that cut harmful greenhouse gas emissions to our region can thrive in a changing climate.

The K4C is a partnership of local governments of all sizes. We combine our knowledge, resources, and advocacy power to accelerate collective climate action in King County and across the state.

Since it began in 2012, the K4C has grown to 18 partners – King County, Bellevue, Burien, Issaquah, Kenmore, Kent, Kirkland, Lake Forest Park, Mercer Island, Normandy Park, Redmond, Renton, Sammamish, Seattle, Shoreline, Snoqualmie and Tukwila, and the Port of Seattle – who together represent 80% of the King County population.

K4C partners work together to reduce harmful greenhouse gas emissions by sustainably increasing mobility, investing in renewable energy, promoting clean energy use in buildings and vehicles, and expanding farm and forest protection.

How to join

All cities in King County are welcome to join the K4C. Membership requires signing an Interlocal Agreement, modest annual dues based on the member’s population size that are invested in projects, and a commitment to provide staff resources for regular meetings. Members are encouraged to sign the Joint Climate Action Commitments that outline actions and policies to meet our ambitious regional climate targets.

K4C events

October 19, 2021 Town Hall recording
King County Executive Dow Constantine, Redmond Mayor Angela Birney, Issaquah Mayor Mary Lou Pauly, and Burien Councilmember Nancy Tosta hosted a virtual Town Hall for King County residents. King County staff recapped discussions from the October 14th Elected Official Work Session and facilitated a series of panel discussions with elected officials. Constituents asked questions throughout, and key themes of interest/questions included:

  • Funding retrofits for existing buildings (both commercial and residential) to remove natural gas, become more efficient, and add cooling
  • Plans cities have to adopt more stringent building codes and how to bolster these efforts
  • How to encourage more cities to join the K4C
