Napa County Regional Climate Action and Adaptation Plan Yountville Town Council
September 16, 2025
What is the RCAAP?
• Comprehensive, long-range, climate plan
• Achieves countywide GHG reduction targets and carbon
neutrality goals for 2030 and 2045
• Provides countywide strategy for climate adaptation and resilience.
• Builds on existing sustainability & climate initiatives • Regional, coordinated plan
• Addresses regional emissions and regional climate change impacts (all jurisdictions)
• Prepared and reviewed by member agencies of the Climate Action Committee (CAC):
• County of Napa
• City of American Canyon
• City of Calistoga
• City of Napa
• City of St. Helena
• Town of Yountville

Implementation &
Monitoring
• Local adoption of the RCAAP (all 6 jurisdictions)
• Regionally-coordinated implementation strategy
• Ongoing Monitoring, Reporting, Updating
• Periodic GHG inventory updates
• Annual reporting on targets and key indicators
• Periodic updates to RCAAP
• Order-of-magnitude cost estimates for limited subset
of measures
• 9 GHG measures and 10 adaptation measures
• Important note: Not a full-scale cost estimate for entire plan.
• Potential funding & financing sources identified
• Funding and financing strategy tied to timing and
prioritization will be critical
