IWCA is a membership-driven effort, open to any winery that views climate change as a serious threat and is committed to reducing their own emissions. Our member wineries—big and small, from different parts of the globe—are all committed to the same values: reducing their greenhouse gas emissions, improving their land stewardship, protecting biodiversity, and being socially-responsible, locally-engaged businesses.
IWCA membership is multi-tiered and rigorously vetted to ensure that applicant members and members are held accountable to their commitments and demonstrate tangible progress towards carbon neutrality by 2050.
