One Cooling Credit offsets one ton of CO2 warming for a year. How does one gram of SO₂ offset one ton of CO₂ warming for a year?
Estimates vary, but a leading researcher cites "geoengineering’s leverage is very high — one gram of particles in the stratosphere prevents the warming caused by a ton of carbon dioxide," and “a gram of aerosol in the stratosphere, delivered perhaps by high-flying jets, could offset the warming effect of a ton of carbon dioxide, a factor of 1 million to 1."

Cool the Planet, One Credit at a Time
Inspired by nature’s cooling wonders, like volcanic eruptions, our balloons carry a precisely measured amounts of a naturally occurring substance into the stratosphere—think of it as sunscreen for the Earth!
What’s a Cooling Credit?
One Cooling Credit offsets the warming effect of 1 ton of CO₂ for an entire year. To put that into perspective, the average American generates 16 tons of CO₂ annually.
How It Works:
Your purchase funds the release of at least 1 gram of reflective particles ("clouds") into the stratosphere. After deployment, you'll receive a detailed confirmation email with video of exact location, time, date, and serial number(s) of your Cooling Credits, as well as the release altitude.
Why over 770 people have chosen us to cool Earth:
- Transparent: Track your Cooling Credits on your account page.
- Flexible: Refunds available anytime before deployment.
- Fast: Current median fulfillment time is 30 days and 8 hours.
Bulk Options for Companies:

We should obviously be doing solar geoengineering. We are on track to radically reduce emissions in the coming years but thermal damage will lag our course correction so most of our climate pain is still ahead of us. Why risk destabilizing the West Antarctic ice sheet or melting the arctic permafrost or wet bulbing a hundred million people to death? Solar geoengineering can incrementally and reversibly buy down the risk during this knife-edge transition to a better future. We owe future generations to take all practical steps to dodge avoidable catastrophic and lasting damage to our planet.

It’s a small way I can help with a seemly very large problem! For what it’s worth, $200 offset 20 tons of CO2 is a great win!

At some point, you learn about reflective particles as a potential cooling method. The next question would be: 'Is anyone doing this now?' This led to the discovery of Make Sunsets, a team that not only explores solar radiation management techniques but also works to implement them. It's incredibly reassuring to see a group like Make Sunsets pushing the boundaries of scientific research, aiming to create a cooler, more sustainable future for everyone.
