SF Climate Week at Yerba Buena Gardens

Yerba Buena Gardens is hosting San Francisco Climate Week’s public kickoff on Saturday, April 18, with a free Earth Day festival and green business expo from noon to 3 p.m. (sfenvironment.org) The event is organized by the San Francisco Environment Department with the Yerba Buena Gardens Conservancy and Climatebase, and it is billed as the official welcome day for SF Climate Week 2026. (sfenvironment.org) SF Climate Week itself runs from April 18 through April 26, 2026, and the main calendar lists more than 500 events across the Bay Area. Climatebase said last year’s edition drew more than 25,000 attendees across 650 events. (sfclimateweek.org, stories.climatebase.org, luma.com) At Yerba Buena Gardens, organizers are pitching a broad public-facing mix rather than a closed industry summit: green businesses, community groups, family activities, music, vendors, and sustainability programming. Event listings describe it as an Earth Month celebration tied to the week’s larger climate agenda. (eventbrite.com, sf.funcheap.com) That format puts one of San Francisco’s biggest climate gatherings in a downtown park instead of a conference hall. Yerba Buena Gardens sits in SoMa, next to museums, hotels, and the Moscone convention district, making it a visible stop for both residents and conference-style visitors. (ybgc.org, sfclimateweek.org) The week around it is much bigger than one fair. The official calendar includes policy talks, startup showcases, investor events, arts programming, and sector-specific sessions on energy, housing, food, and transportation. (sfclimateweek.org, sfcw.climate-week.org) Climate Week has grown into a decentralized model, with outside groups hosting their own events under the umbrella calendar rather than one organizer running every panel. The official site says participants can submit events, and the public schedule spans San Francisco, Oakland, and other Bay Area locations. (sfclimateweek.org, luma.com) For people deciding whether to go, the practical details are simple: the Yerba Buena Gardens kickoff is free, outdoors, and scheduled for Saturday, April 18, from 12 p.m. to 3 p.m., with additional Climate Week events continuing through April 26.
