Make Sunsets

Make Sunsets is pioneering a bold approach to climate mitigation by deploying sunlight-reflecting particles into the stratosphere — a modern, controlled version of the cooling effect seen after major stratovolcanic eruptions like Mount Pinatubo (1991) and Hunga Tonga (2022). By turning solar geoengineering into a scalable service, the company offers a pragmatic way to temporarily reduce global temperatures while the world catches up on excess emissions reductions and carbon removal. Their Cooling Credits let individuals, companies, and eventually governments fund these deployments, creating a rare 1-to-1 million leverage against CO2 emissions.
