During SF Climate Week, Climate One hosted 2025 Goldman Environmental Prize winners Laurene Allen and Carlos Mallo Molina. These inspiring leaders protect their communities from powerful interests, often at great personal risk. Join Co-Host Greg Dalton to explore their extraordinary actions.

Carlos Mallo Molina led a campaign to stop Fonsalía Port construction, canceled in October 2021. The terminal threatened a 170,000-acre marine protected area in Tenerife, home to sea turtles, whales, and sharks. He now envisions a marine conservation and education center.

Laurene Allen protected New England families from PFAS-contaminated drinking water. Her campaign pressured an industrial giant, responsible for toxic "forever chemicals," to close in May 2024, ending over 20 years of pollution.
