The Certified California Sustainable Winegrowing Programme is being launched by the state’s Sustainable Winegrowing Alliance.
It will be open to all producers but they will need to meet 58 criteria to show a “process of continuous improvement” on sustainability.
Winery and vineyard operations will be assessed and firms will have to implement an annual action plan.
Wine Institute president and chief executive Bobby Koch said: “Third-party certification helps California’s wine community speed efforts to create a
healthier environment, stronger communities and vibrant businesses.
“The programme reflects the California wine community’s commitment to continually produce the finest-quality wine and grapes with practices that are environmentally and socially responsible.”?Chris Savage, senior director of environmental affairs at Gallo, said sustainability in California was “not just a statement of a programme but an embedded philosophy that we live by each and every day”.
