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.

John Doerr, venture capitalist and author of the best-selling book *Measure What Matters*, popularized OKRs (objectives and key results). Now, in *Speed & Scale: An Action Plan for Solving Our Climate Crisis Now*, Doerr and Kleiner Perkins advisor Ryan Panchadsaram argue that the same management tools can be applied to prevent the growing climate crisis.

Join The Commonwealth Club and Climate One on December 6, 2021, as John Doerr and Ryan Panchadsaram discuss this pressing issue. They will explore how lessons learned at the highest levels of business might address climate change, in conversation with Greg Dalton of Climate One.
