Marin County Climate Action Plan (2015 Update)

The 2015 Marin County, California Climate Action Plan (CAP) updates the 2006 Marin County Greenhouse Gas Reduction Plan. The majority of the plan focuses on mitigation, providing an update of GHG emissions in 2012, forecasts of emissions for 2020, and an assessment of actions that the County will take to further reduce emissions by 2020. In addition, Chapter 8 focuses on adaptation, providing an overview of Marin’s expected climate risks, a summary of actions-to-date, and recommended next steps.

Chapter 8 begins with a discussion of Marin’s projected climate impacts. Overall, Marin expects to see warmer temperatures, drier summers, and wetter winters - but notes that the County’s geographic complexity and the inherent difficulties in modeling precipitation mean that the county must plan for a wide range of future conditions and impacts. Climate change will likely exacerbate existing challenges such as inland flooding and could introduce new challenges such as erosion and coastal flooding due to sea-level rise. 

The chapter then describes adaptation efforts already underway in Marin including collaborations with other public entities, non-governmental organizations, and the private sector to assess coastal risks; and efforts to incorporate climate adaptation into comprehensive planning documents such as the Vegetation and Biodiversity Management Plan. Building on these adaptive actions, the report argues that the County must consolidate its efforts across sectors and analyze if resources or being deployed efficiently and effectively. Additional actions suggested include a countywide vulnerability assessment, improved collaboration among stakeholders, and the establishment of additional funding sources to support adaptation initiatives.

The adaptation chapter concludes with a high-level discussion of impacts to various sectors and potential actions that each sector could take. The sectors addressed include water, natural heritage (ecosystems), transportation, agriculture, energy, human health, and the built environment. Some example recommended strategies include asking the water sector to anticipate higher water treatment costs, the creation of “no-wake zones” to reduce erosion, for the transportation sector to address worker safety with regards to extreme heat, and increasing Marin’s power storage capacity. 


The Marin County Board of Supervisors adopted the CAP and updated emissions reduction target of 30% below 1990 levels by 2020 on November 10, 2015. The 2015 CAP Update was prepared by ICF International for the County of Marin. Funding for the CAP Update was provided in part by the Marin County Energy Watch, a joint project of Pacific Gas and Electric (PG&E) and the County of Marin.
