Keeling Curve Prize Application


The Global Warming Mitigation Project’s flagship program, the Keeling Curve Prize, awards $50,000 annually to each of 10 global projects that demonstrate the ability to reduce, replace, or remove greenhouse gases in the atmosphere and oceans. Since 2018, we’ve awarded $1.75M to 60 nonprofits, for-profits, and startups, vetted more than 1,130 viable solutions, and grown one of the largest networks of global warming mitigators in the world. The initiatives we’ve awarded are currently projected to reduce 3.27 gigatons of CO2e emissions this year alone (self-reported data).
