The King County-Cities Climate Collaboration (K4C) is a partnership of local governments taking collective action to improve our communities' health and resiliency in the face of climate change. Founded in 2011 by King County and several partner cities, including Mercer Island, the
now includes 16 member cities and the Port of Seattle, representing 80% 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.
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 towards a county goal of 80% GHG reduction by 2050.
The K4C is currently running a
short online survey
to find out more about what climate action means to local residents. Please visit the survey today!
