SF Climate Week is California’s largest climate summit — and one of the largest climate gatherings in the world.

In 2025, over 25,000 attendees came together across 650+ events throughout the Bay Area, featuring hundreds of climate leaders, innovators, and changemakers — including Vice President Al Gore, Speaker Emerita Nancy Pelosi, SF Mayor Daniel Lurie, rock climber Alex Honnold, political commentator Van Jones, and hundreds more.

The week brings together the entire climate ecosystem — from technology founders and investors to activists, policymakers, artists, scientists, and citizens — for a dynamic series of events spanning climate technology, policy, energy, nature, circular economy, adaptation, finance, activism, and beyond.

SF Climate Week is a decentralized, community-driven celebration of climate action and innovation — uniting organizations across sectors to accelerate solutions for a livable planet. Whether it’s a startup showcase, a city-hall policy roundtable, a rooftop mixer, or a hackathon, every event contributes to a shared movement to scale impact and accelerate climate solutions. 

Join us April 18 – 26, 2026 for the next annual SF Climate Week.

SF Climate Week is part of the Climate Week Network (climateweeknetwork.org), a philanthropically supported initiative led by Climatebase.org￼ — the leading platform for climate careers and community.
