California Natural Resources Agency Celebrates Earth Week with Discussion on Green Progress in the Golden State, April 23, 2026 Noon-1 PM

California has turned policy into results you can see and feel in daily life. Safer drinking water flows from the tap in communities long left behind. Local food systems grow stronger, connecting farms to schools and families and cutting waste. More lands and coastal waters are conserved to protect ecosystems and expand access. Clean energy now powers more homes and businesses, reducing pollution and lowering costs over time.
