Washington Governor Jay Inslee will join California Governor Jerry Brown , Oregon Governor John Kitzhaber and  British Columbia Premier Christy Clark  to announce a historic partnership on climate policy in a news conference on Monday,   The event will provide details of an agreement aligning the governments’ strategies that combat climate change and promote clean energy.

The agreement will be based on the recognition that the West Coast is bounded together by a common geography, shared infrastructure and a regional economy with a combined GDP of $2.8 trillion, making it the world’s fifth largest economy.

The Pacific Coast Collaborative was established in 2008 to address the unique and shared circumstances of the Pacific coastal areas and jurisdictions in North America by providing a framework for co-operative action, a forum for leadership and the sharing of information on best practices, and a common voice on issues facing coastal and Pacific jurisdictions.
