Taking collective action to decarbonize the global wine industry
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.

Since its founding in 1870, Familia Torres has combined tradition and innovation with the aim of making premium wine and brandy, always with the utmost respect for the environment. It has historically had wineries and vineyards in its homeland Penedès, Conca de Barberà, Priorat and Costers del Segre, and it is also present nowadays in other Spanish wine regions as well as Chile and California. The commitment to protect the land and environment, the pursuit of excellence, and a passion for wine culture have been passed down from generation to generation. Fifth generation is focusing today on making wines from unique vineyards and recovering ancestral varieties in Catalonia, as well as in other parts of Spain and Chile. Familia Torres is adapting to global warming while contributing to mitigate its effects through its ambitious environmental program, Torres & Earth, established in 2008.
