Case Study on The King County - Cities Climate Collaboration (K4C)

This Georgetown Climate Center (GCC) case study on the King County-Cities Climate Collaboration (K4C) explores how local governments and other partners are coordinating at the regional scale to reduce greenhouse gas emissions across the King County region of Washington state. This case study explores how the K4C was formed and has organized its decisionmaking, what local governments and other stakeholders are involved in the collaborative, what roles it is playing to reduce emissions in the region, and how the collaborative funds its activities. This case studies can be used by local and regional governments to help them develop strategies for coordinating across jurisdictional lines to support climate action in their regions.

The K4C is a collaborative between King County, WA and cities within the County; it currently has fourteen local government members that have joined by signing an Interlocal Agreement. This case study explores how K4C’s efforts – which have primarily focused on climate change mitigation (reducing emissions) – have resulted in the adoption of shared countywide greenhouse gas reduction targets. It also explores how the collaborative has helped to produce policy recommendations that local governments in the region could adopt to meet emission reduction goals in specific areas, like electric vehicle usage and commercial energy benchmarking. 

The K4C is helping local governments and other partners in the region coordinate climate action by: 

  • coordination outreach to develop, refine and utilizing common messaging and tools for reaching out to decisionmakers, stakeholders, other cities, and the general public;
  • collaborating to develop consistent standards, benchmarks, strategies and goals for reducing emissions;
  • sharing local success stories, challenges, data, and products that support or enhance climate mitigation efforts; and
  • collaborating to secure funding to support implementation of projects and programs.

This case study is part of a series of six case studies that GCC developed to explore lessons that cities and communities across the country are learning as they work together across jurisdictional lines on climate action. Each case study in this series explores the roles that these collaboratives are playing to support climate action in their regions, how the collaboratives are helping to align resources and policies among participating jurisdictions, and how they are structured and funded. A synthesis report also explores lessons that can be learned by comparing the efforts of each collaborative on climate policy in their regions.
