Mr. Torres and his father, Miguel A. Torres, who led the company until 2012, have transformed Familia Torres from simply a top Spanish wine producer into an industry leader in the fight against climate change. This has meant both finding innovative ways to counter the effects of climate change on the wines and diminishing its own carbon emissions.

With six wineries in Spain, along with estates in Chile (Miguel Torres Chile) and in California (Marimar Estate in the Russian River Valley, run by the elder Mr. Torres’s sister, Marimar Torres), this family company has the size to exert the sort of influence impossible for small farmers.

To make the case that climate change poses a dire threat to the wine industry and requires a concerted response, Torres has teamed with Jackson Family Wines, another international wine company based in California, to form International Wineries for Climate Action.

The organization, which has set up a rigorous standard for admission, is set to announce additional members by the end of October, and will lobby others in the wine industry to make reducing carbon emissions a top priority.

Torres can lead by example. From 2008, when it audited its carbon emissions from the vineyard through transporting the finished product to market, the company has reduced its carbon output by almost 28 percent, with a goal of 50 percent by 2030, and 80 percent by 2045. This corresponds to goals for limiting global warming set out by the United Nations Intergovernmental Panel on Climate Change.
