In 2018, Opus One was certified as a Napa Green Winery which encompassed the winery as a whole including production, hospitality, human resources, and administration. This certification implements standards to save energy, conserve water, prevent waste through recycling and compost programs, reduce carbon footprint, and a commitment to social equity. In 2022, Opus One also received the Napa Green Vineyard Certification, which focuses specifically on climate action, regenerative farming, water use efficiency, tree preservation, and social equity. Increasing the resilience of our vineyards, businesses, and communities is a primary objective of the Napa Green program. Opus One was the first winery to receive both a Napa Green Winery and Napa Green Vineyard Certification.
