San Joaquin County now has its first coordinated, county-wide climate plan. The Stockton Metropolitan Statistical Area Comprehensive Climate Action and Adaptation Plan, known as the CCAAP, was drafted in March 2026 under the U.S. Environmental Protection Agency's Climate Pollution Reduction Grants program, with the City of Stockton serving as the grant recipient and lead author. The plan covers the entire MSA, which is the county itself: Escalon, Lathrop, Lodi, Manteca, Mountain House, Ripon, Stockton, Tracy, and the unincorporated areas, spanning roughly 1,392 square miles and more than 780,000 residents.
