Our vision cannot be achieved without the participation and leadership of individual wineries.
IWCA is open to any winery, from any country, that:
is involved in the production process from grape-growing to bottling.
recognizes that climate change is the most significant threat to the wine community.
is willing to take strategic action to accelerate innovative climate solutions.

WHY JOIN IWCA?
IWCA creates a collaborative community of like-minded businesses that encourages the knowledge sharing and exchange of best practices for mitigating climate impacts in vineyard and winery operations.
The more wineries that participate in IWCA, the louder our voice will be to raise awareness on climate change and to urge immediate, global action.
Given the science-based approach of IWCA and the strictness of our requirements, participating wineries are perceived as strongly and sincerely committed in the fight against climate change.
IWCA employs a three-tiered membership system that allows a diversity of wineries to join our movement—including those who might be early in their sustainability journey but are committed to climate action. Our membership requirements and milestones keep us accountable to achieving ambitious and tangible impact.
Any winery interested in becoming an IWCA member but that has not yet fulfilled the greenhouse gas inventory requirement can join IWCA as an Applicant. To become an Applicant, however, the winery must have completed a credible baseline GHG inventory encompassing at least Scopes 1 and 2, or have a plan to complete a credible baseline GHG inventory that encompasses Scopes 1-3. Applicants have one year to meet IWCA membership requirements and become a full Silver- or Gold-level member.
Must fulfill requirements #1 and #2, at a minimum.
Commit to becoming Net Zero by 2050 across Scopes 1-3, ensuring consistent reductions of emissions per liter of wine produced to meet intermediate targets by 2030 in alignment with the United Nation’s Race To Zero Campaign.
Complete a minimum baseline third-party verified GHG inventory for a standardized set of emissions categories across Scopes 1-3 (using the World Resources Institute’s GHG Protocol and ISO-14064 process), including 90% of the organization’s volume within the region where its main winery is.
Must fulfill requirements #1, #2, #3, and #4.
Have winemaking operations be at least 20% powered by onsite renewable energy, as certified by independent audit.
Demonstrate a consistent reduction of emissions per liter of wine produced from a baseline emissions inventory year, as proof of proactive ongoing commitment. This percentage is dependent on the baseline year and is proportional towards the winery’s Net Zero target for 2050.
