warrantd contributes 1.5% of every purchase to fund permanent carbon removal. Every credit pack and subscription payment automatically directs a portion to removing CO₂ from the atmosphere.
This isn't an offset program. We fund technologies that physically pull carbon dioxide out of the air and store it permanently.
We use Stripe Climate to route contributions to early-stage carbon removal companies through Frontier, an advance market commitment to buy over $1 billion in permanent carbon removal by 2030.
Frontier funds technologies like direct air capture, enhanced weathering, and bio-oil sequestration. These are early-stage approaches that need buyers now to reach the scale the climate requires.
Reducing emissions is essential but not sufficient. Even under optimistic scenarios, we will need to remove billions of tons of CO₂ already in the atmosphere. The problem is that permanent carbon removal is expensive today because the market is young.
Buying early helps these companies move from lab to field, drive costs down, and build the capacity we need. This is the same logic that made solar panels affordable: early buyers funded the learning curve.
warrantd is a tool for people who think carefully about evidence. Climate science is clear, and we think tools built for rigorous thinkers should reflect that clarity in how they operate.
Our founder worked in sustainability at Yale and in the solar industry. This commitment comes from direct experience, not a marketing strategy.
Stripe Climate contributions are tracked and verified through Stripe's infrastructure. We don't handle the funds directly. Stripe reports on the carbon removal projects funded and the tons of CO₂ removed across its portfolio.
You can learn more about the projects and their progress on the Stripe Climate page.
