The Clean Lighting Coalition
The Clean Lighting Coalition was CLASP’s successful global campaign that catalyzed a universal transition to LEDs, guaranteeing a future lit with efficient bulbs.
About the campaign
CLASP’s Clean Lighting Coalition (CLiC), created in 2021, was a campaign created to drive universal adoption of efficient, safe lighting. CLiC was powered by experts delivering undeniable data about the crosscutting benefits of a global transition to LED lighting from incumbent technologies like incandescent and mercury-ladened fluorescent bulbs.
The campaign brought together nearly 300 advocate and technical partners spanning every corner of the globe, from civil society to government to industry, from climate to health to waste, to make the case for a global transition to LEDs. The coalition supported local, national, regional, and international pro-LED lighting policy progress.
Armed with sector leading data and technical support from CLiC and partners, Africa region negotiators to the Minamata Convention on Mercury ushered decisions that successfully phase out fluorescent lighting globally and completely by 2027 – avoiding nearly 3 gigatons of CO2 through 2050. The effort received an endorsement from Eileen Mioko Smith, a founder of the mercury-free movement.
The Clean Lighting Coalition campaign concluded in May 2025.
