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."

Give the Gift of a Cooler Planet 🌍✨
Looking for a meaningful, unforgettable gift? The Make Sunsets Gift Card is your chance to help someone take direct action against climate change. Perfect for eco-conscious friends, family, or anyone who dreams of cooler future.
With this gift card, recipients can purchase Cooling Credits, offsetting the warming effects of CO2 emissions by funding real, measurable deployments of SO₂ into the stratosphere. Each Cooling Credit offsets the warming of one ton of CO2 for a year—the perfect way to make an impact and inspire hope.
Why This Gift?
- Sustainable Impact: Support cutting-edge solutions proven to cool the planet, inspired by natural volcanic cooling.
- Simple & Powerful: Every gift card funds direct, measurable climate action—no fluff, just results.
- Great for Everyone: Ideal for eco-enthusiasts, climate activists, or those just starting their sustainability journey.
How It Works
- Choose the gift card value that works for you.
- The recipient redeems it toward their Cooling Credits purchase.
- Together, you contribute to deploying SO₂ safely into the stratosphere, making the world a little cooler.
💙 Because nothing says love like helping save the planet.

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.
