Cooling Credits

Cool the Planet, One Credit at a Time Inspired by nature’s own cooling events—like the Mt. Pinatubo eruption in 1991 —we launch balloons that release precisely measured amounts of naturally occurring compounds high into the stratosphere. Think of it as sunscreen for the Earth: a reflective shield that helps our planet stay cooler. What’s a Cooling Credit? Each Cooling Credit represents the release of just 1 gram of SO₂ into the stratosphere—enough to offset the warming effect of 1 ton of CO₂ for an entire year. That’s a 1-to-1,000,000 leverage ratio in climate impact. Learn how scientists calculate that. Why 1,000+ people have joined us to cool Earth Affordable: Why it costs only $1–$5 to offset the warming effect of 1 ton of CO₂ for a year Transparent: Track every Cooling Credit on your account page. Fast: Current median fulfillment time is 22 days and 15.5 hours. Natural: We mimic the cooling effect of certain stratovolcanic eruptions. How many should you buy?
