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.


IWCA joins United Nations’ Race to Zero Campaign, becoming the first member representing the wine and agricultural industry.


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, all members are credibly committed to the same overarching goal: to become Net Zero by 2050 across Scopes 1-3, ensuring constant reductions to meet intermediate targets by 2030 in alignment with the United Nations’ Race To Zero Campaign.

Founding Members Founding Members

IWCA Members

Any winery having applied to join IWCA, and having proven themselves compliant with the IWCA entry requirements, will be able to become either a GOLD or SILVER level IWCA Member upon approval by the IWCA Selection Committee.

IWCA Applicants

Any winery interested in becoming an IWCA Member that has not yet fulfilled the GHG inventory requirement will be considered an IWCA Applicant. IWCA Applicants must demonstrate positive intent, as defined by taking steps to calculate and verify their emissions, to becoming IWCA Members (Gold or Silver-level) within one year after signing onto this Standing Rules document or they forfeit their Applicant status.

Friends of IWCA

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

Gold Members: must fulfill #1#2#3#4 Silver Members: at minimum #1#2

  1. To commit to becoming Net Zero by 2050 across Scopes 1-3, ensuring constant reductions to meet intermediate targets by 2030 in alignment with the United Nations’ Race To Zero Campaign.
  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 is.
  3. To be at least 20% powered by onsite renewable energy (excluding the purchase of RECs or other offsets).
  4. To demonstrate a constant reduction of CO2 emissions 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.
