The King County-Cities Climate Collaboration (K4C) is a partnership consisting of local governments taking collective action to improve the health of various communities in the face of climate change.

The K4C is currently running a short online survey to find out more about what climate action means to local residents.

The city of Mercer Island engages frequently in this forum to enhance its capacity in sustainability programs and amplify its voice in regional and state climate policy.

In November 2019, the city adopted an updated set of K4C Climate Commitments pledging to continue work toward a county goal of 80 percent GHG reduction by 2050.

Founded in 2011 by King County and several partner cities, including Mercer Island, the collaboration now includes 16 member cities and the Port of Seattle, representing 80 percent of the county’s population.

The K4C pursues wide-ranging joint initiatives to increase regional mobility, invest in renewable energy, promote clean energy in buildings, expand farm and forest protection, as well as other measures to reduce greenhouse gas (GHG) emissions.
