What is IWCA

The wine industry is one of the agricultural activities most affected by global climate change. Grapevines are extremely sensitive to subtle changes in weather, making grapes particularly vulnerable to heat and drought, and this could ultimately put the quality of our wines at risk.

International Wineries for Climate Action (IWCA) is a collaborative working group of environmentally committed wineries focused on a science-based approach to reducing carbon emissions across the wine industry. Each member within IWCA takes responsibility to hold ourselves and each other accountable to build a cleaner, more resilient wine community for future generations.

IWCA is open to wineries from any country who recognize that climate change is the most significant threat facing the wine industry, and who are guided by the urgency for strategic action that accelerates the implementation of strategies and innovative solutions to tackle climate change.

Our goal is to share best practices that mitigate climate impacts in vineyard and winery operations so that we can act collectively to decarbonize the global wine industry today, by applying direct solutions avoiding offseting carbon credits.

IWCA was co-founded by Familia Torres and Jackson Family Wines, two leading wineries with a multigenerational vision rooted in environmental stewardship and responsible business practices.


IWCA has received the 2019 Wine Enthusiast Wine Star Award for Social Visionary on the Year.

Our Mission

Our mission is to galvanize the global wine community towards creating climate change mitigation strategies and decarbonizing the industry. We seek to raise awareness of the urgent need to address the effects of climate change, and to promote the adoption of greenhouse gas emissions (GHG) footprint inventories and emissions reduction strategies.

We focus on the development of a standardized methodology that accounts for annual GHG emissions (Scopes 1, 2 &3) and strategies and best practices to reduce carbon emissions.

As an international working group, each member of the IWCA will target an overall reduction in greenhouse gas emissions (GHGs) of 50% by 2030, aiming to become Climate Positive by 2050.

Founding Members Founding Members

IWCA Members

Any winery having applied to join IWCA and having provided documentation that has been verified to comply with the IWCA entry requirements will be able to become an IWCA Member once the founding members accept its candidature.

IWCA Applicants

Any kind of individual, association or society sharing the IWCA values and willing to give support to the working group can join as a Friend of IWCA.

Why join IWCA

Because the global climate crisis requires immediate action.

  • By joining IWCA, your winery has recognized the severity of the climate crisis and is committed to taking immediate action to help reduce the wine industry’s carbon footprint given the direct impact climate change has on our vineyards and wines.
  • The more wineries participating in IWCA, the louder our voice to raise awareness on climate change and urge for immediate, global action.
  • Given the science-based approach of IWCA and the strictness of its requirements, your winery will be perceived as one that is strongly and sincerely committed in the fight against climate change.
  • IWCA creates a space for collaboration that encourages the sharing of best practices that mitigate climate impacts in vineyard and winery operations, from which you can benefit.

Membership Requirements

Because decarbonizing the industry requires commitment and vision.

  1. To be at least 20% powered by onsite renewable energy (excluding the purchase of RECS or other offsets).
  2. To have completed a minimum baseline third-party verified GHG inventory for a standardized set of emissions categories across Scopes 1-3 (using WRI GHG protocol and ISO 14064 process), including 90% of the organization’s volume within the region where its main winery and vineyards are located.
  3. To demonstrate at least a 25% reduction of CO2 emissions per unit of wine produced from a baseline emissions inventory year as proof of proactive ongoing commitment.
  4. To have a mid-term objective to reduce total emissions 50% by 2030, aiming to become Climate Positive by 2050.
