Jack Johnson, 2025-2026

Jack Johnson, Waste Management Supervisor, City of San Mateo (Term: 2025-2026)

I am the Waste Management Supervisor for the City of San Mateo. My former roles include Senior Sustainability Specialist with the County of San Mateo Office of Sustainability and Public Education and Outreach Coordinator for Aspen/Pitkin County, Colorado.

I have worked on developing beneficial reuse of greywater on a landfill site, a hydroelectric dam, an innovative e-waste recycling program employing the developmentally disabled, and a large rural mass transit system. I worked to create Colorado’s largest rural compost collection system–SCRAPS—a public/private partnership involving the municipally owned compost facility, private haulers, and both residential and commercial customers.

My main interest is in reducing contamination in the organics stream and in the successful implementation of SB1383 statewide. I am a founding member of NCRA’s Zero Food Waste Committee.

For me, collaboration is key. Climate change doesn’t respect geo-political boundaries so if we are going to make progress on our climate goals, we need to work together across those boundaries. I will pursue regional answers and be a strong advocate for zero waste and push for strong, innovative solutions in our region and the state.
