The anti-GHG 501c3
A new tax-advantaged way to take climate action
Our planet needs high-quality, permanent carbon removal, now.
As a 501c3, we pool tax-deductible donations from people, foundations, family offices, and donor advised funds, and make strategic purchases of high-quality carbon removal. We don’t get credits or offsets in return, we just reduce atmospheric greenhouse gases.
Climate scientists agree: it’s not enough just to reduce emissions. We also need to remove large amounts of carbon dioxide already in the atmosphere.
Carbon removal solutions exist, but they’re not growing fast enough, and there aren’t enough of them. We need to rapidly accelerate the deployment of permanent, high-quality carbon removal. To do that, we need policy change, corporate buyers, venture capital, philanthropic support—we need it all. We’re here to channel more of the philanthropic dollars to carbon removal.
Tax-deductible
As a 501c3, donations are tax-deductible, and you’ll receive a tax-compliant receipt via email.
Transparent
We believe in being open about everything we do, from our research sources and methodology to our decision-making process and project portfolio.
Simple
Our work is straightforward by design. We make it easy for anyone to make real change for the planet.
A tax-deductible vehicle for carbon removal.
We use research from leading climate organizations like Frontier and CarbonPlan and evaluate potential recipients against strict criteria to ensure donations drive real impact on the planet. Early donors include Tim Ferriss and Segment co-founder Calvin French-Owen.
Additional
Carbon is removed as a result of the donation, and wouldn’t otherwise have happened.
Verifiable
Providers have scientifically rigorous, transparent reporting on the amount of carbon removed as a result of the purchase.
Long term
Carbon is stored for centuries or millennia.
Ethical
Projects have no negative social and economic impact in the communities they operate in.
Scalable
Projects have the potential to scale to many megatons per year and become drastically more affordable.
Validated
Leading climate experts have published research on or publicly supported the project.
Putting philanthropic dollars behind high-quality carbon removal projects.
Our current project portfolio includes companies like Heirloom and Charm.
Charm uses plants to capture carbon dioxide from the atmosphere, converting biomass into a stable, carbon-rich liquid and pumping it deep underground.
Heirloom is removing 1 billion tons of carbon dioxide by 2035 by using natural processes to engineer the world's most cost-effective Direct Air Capture solution.
