Transparency and Accountability
Certification programs require independent verification, ensuring transparency and public trust. Wineries and vineyards must meet hundreds of rigorous criteria, such as:
- Water and energy efficiency
- Soil health management
- Pest management with minimal chemical use
- Worker safety and welfare
- Wildlife protection and habitat conservation
- Community engagement and neighbor relations
- Waste management and climate action
Major Milestones: California’s Leadership by the Numbers
California’s impact is not just aspirational—it is quantifiable:
- Over 80% of California’s wine cases are produced by certified sustainable wineries
- 54% of California winegrape acreage is certified under CCSW, SIP Certified, LODI RULES, Napa Green, or Fish Friendly Farming
- Annual third-party audits validate ongoing compliance and improvements
- Sonoma and Napa counties hold the greatest concentrations of certifications—Sonoma County alone boasts over 1,100 certified winery and vineyard operations
