Our price per tonne is fixed in USD and shown up front — no hidden fees, and no demand-based surge pricing. Here is everything that fixed price pays for:
Verified, registry-listed carbon credits bought on your behalf.
Screening projects against our integrity standards before we buy.
The fees registries charge to permanently retire a credit.
Your PDF + PNG certificate and the public verify page.
Card, UPI, wallet and PayPal fees charged by our payment providers.
The site, integrations, automation and customer support.
Whatever the breakdown, the climate outcome is fixed: every tonne you pay for is retired one-for-one on a public registry, with a serial you can look up yourself.
