David Lu

David Lu is the co-founder and CEO of Clarity Movement Co., a Berkeley-based climate tech company that deploys hyperlocal air quality monitoring networks across 85+ countries. Growing up in smog-choked Shanghai and arriving to California's startling blue skies as a teenager, he turned personal contrast into a global mission. Clarity's tissue-box-sized solar-powered sensors have recorded over 500 million measurements, informed London's low-emission zones, and earned Lu a spot on TIME's 100 Most Influential Climate Leaders of 2025.
