Ze-Kun Li, Executive director

Ze (he/him) got his first taste of community organizing in 2010, when, as a De Anza College student, he helped organize a 15,000-person march in San Francisco to advocate for adequate educational funding. This invaluable experience created a belief in the power of student organizing and motivated him to successfully run for student body president. As student body president in 2011, he led a group of 75+ student leaders to create systematic changes - including a deal with VTA to create the first community college eco-pass, where students now pay only $7.75 per quarter to have unlimited usage of any Valley Transportation Authority bus and light rail.

Prior to joining Silicon Valley Youth Climate Action, he built multi-sector coalitions in the 9 counties of the Bay Area to support the largest affordable housing bond in the country. Before that, he was the Director of Campaign Operations for a leading California political strategy firm, where he guided California State Senate and State Assembly, Countywide and City Council electoral campaigns to victory. He’s won 24 out of 26 campaigns because he values strategic partnerships, coalition building, in-language communication and utilizes polling and data to inform decisions.

Over a decade of experience working with private, public and non-profit stakeholders has taught Ze to prioritize the philosophy of “people support what they help create.” His innate ability to work collaboratively with stakeholders and students creates synergy that turns an idea into a reality. He is passionate about youth empowerment and helping to mentor the next generation of changemakers to tackle the climate crisis, and creating systematic changes in education to level the playing field to green career opportunities.

Ze holds a B.A. in Political Science from Santa Clara University.
