The 2025 OurCounty Sustainability Plan charts an ambitious path toward a cleaner, more equitable, and climate-resilient future for Los Angeles County.
On November 4, 2025, the Los Angeles County Board of Supervisors adopted the 2025 OurCounty Sustainability Plan, the nation’s most ambitious regional sustainability roadmap. Building on the 2019 plan, the updated plan includes 179 action items designed to strengthen community well-being and resilience. Since 2019, the County has made major strides, including cutting greenhouse gas emissions from County operations by 40%, creating over 110 acres of new parkland in unincorporated areas, installing 1,500 EV chargers, and investing nearly $1 billion in multi-benefit stormwater capture projects.
Developed through extensive community engagement, the 2025 Plan integrates six years of progress, public feedback, and new data. Nearly 70% of survey respondents agreed that L.A. County is more sustainable today than five years ago, with air quality remaining their top concern. The plan envisions clean air, safe and accessible neighborhoods, affordable housing, and climate-ready communities that can withstand extreme weather. By consolidating the County’s diverse sustainability efforts under a single, unified framework, the plan ensures transparency and coordination across departments and jurisdictions, enabling collective progress toward a just and equitable green economy.
The plan also introduces several new and expanded focus areas, including wildfire risk management, community resilience, Tribal and Indigenous partnerships, ocean and marine systems, green goods movement, green economy, and resource circularity. These initiatives highlight the County’s forward-looking approach to climate action, emphasizing clean energy, sustainable materials, equitable workforce development, and local innovation.
