International Wineries for Climate Action (IWCA) is a collaborative working group of environmentally committed wineries taking a science-based approach to reducing carbon emissions across the wine industry.

Our goal is to share best practices that mitigate climate change impacts in vineyard and winery operations so that we can act collectively to decarbonize the global wine industry—applying direct solutions that avoid purchasing carbon offset credits.

IWCA was founded in 2019 by Familia Torres (Penedes, Spain) and Jackson Family Wines (California, USA) to galvanize the global wine community to create climate change mitigation strategies and decarbonize the industry.

Since our founding, IWCA—registered as a 501(c)6 nonprofit organization in the United States—has welcomed more than 30 new member and applicant member wineries.


We have developed rigorous methodologies to measure greenhouse gas emissions (GHG) footprints. We are raising awareness in the viticulture community of the urgent need to reduce greenhouse gas emissions. And we share strategies and best practices to reduce emissions in the wine sector as we mobilize wineries worldwide to adopt emissions reductions strategies.


Climate change poses an urgent and existential threat to the wine sector.

Global temperature changes are fundamentally shifting where, when, and what kind of wine can be grown, putting the future of multi-generational local wineries at risk. Unpredictable weather patterns are affecting crop abundance and grape chemistry and quality. Increasingly frequent extreme events, from droughts to flooding to wildfires, place entire harvests—and businesses—in danger.


If you share our sense of urgency and our vision of a climate-positive wine sector, join us as a member winery and stay tuned for other ways to support our mission.
