Climate Change

This page provides an overview of climate change in Washington State, with an emphasis on local and state governmental responses.


The concern about climate change has been widely recognized on a global, national, and regional level. "Global warming" refers to increases in global temperatures resulting from an accumulation of greenhouse gases in the atmosphere. Greenhouse gases include carbon dioxide, methane, and chlorofluorocarbons. These gases trap the sun's heat as it is radiated from the earth, and prevent it from escaping back into space. State and local governments are addressing climate change in their plans and policies and starting to take actions to reduce greenhouse gases.

MRSC’s Local Climate Response Project

In July 2021, MRSC launched its Local Climate Response Project, with a focus on helping local governments reduce greenhouse gas emissions, center equity in climate planning efforts, and adapt to and become more resilient to the effects of climate change.

One key early project accomplishment has been our survey of staff from cities, counties, special purpose districts, and tribes across the state.The purpose of the survey was to assess current climate planning efforts and potential resources MRSC can provide to help local governments develop and implement climate plans and policies. Read the full report or check out this blog, MRSC Releases Results of Local Government Climate Response Survey, which summarizes key findings.

By early 2022, our climate-related resources will be expanded and reorganized. Watch for:

  • An interactive map showing the latest climate-related policies and plans adopted by local governments in Washington State, with links to these resources.
  • New topic pages focused on equity in climate planning, local strategies to reduce greenhouse gas emissions, and preparing for/adapting to the effects of climate change at the local level.
  • A collection of resources to assist local governments in climate action planning, including links to toolkits, technical resources, and funding opportunities.
  • A 3-part webinar series.

As many local governments have expressed interest in financial resources for climate planning and implementation, MRSC has gathered the resources below for climate mitigation, adaption and resilience efforts. The information is divided into state-based and out-of-state listings.

  • King County C-PACER Program (2021) — In 2020, Washington State passed HB 2405 authorizing counties to establish Commercial Property Assessed Clean Energy + Resiliency (C-PACER) programs. C-PACER is a financing mechanism to help commercial, industrial, agricultural, and multi-family buildings become more efficient and resilient.

Nationwide Funding

MRSC will continue to develop the tools, training, and curated resources local governments need to develop and implement effective and equitable climate plans and policies. We will also continue to publish blogs on all aspects of climate change and its impact on local communities. Stay tuned and reach out to Lisa Pool if you have any questions about our Local Climate Response Project.
