Taking collective action to decarbonize the global wine industry.

IWCA is a collaborative of wineries committed to reducing carbon emissions across the wine industry.

As a member of the United Nations Race to Zero campaign, IWCA commits to achieving and reporting on progress towards "net zero."

We are driven by our member wineries, who gain tools and knowledge, recognition, and a like-minded community in IWCA.

Catch up on what we have been working on and our efforts to decarbonize the wine sector.


Since IWCA was founded in 2019, we have grown into an international collective of wineries dedicated to taking climate action.

Our inaugural 2021 report highlights our efforts and IWCA member wineries' progress towards reducing their GHG emissions.
