Shred your carbon.
Then look up the receipt.
Most offsetting asks you to take its word for it. We hand you the registry serial number of the exact tonnes retired in your name — go and check them.

Measure
Five questions about how you live — travel, diet, home, spending — and you have your annual footprint in tonnes of CO₂e.
- 02
Fund
Retire it once, or set a monthly amount. Your money buys credits from a curated portfolio of verified removal and avoidance projects.
- 03
Verify
The credits are retired on a public registry in your name, and the serial numbers land in your dashboard for you to check.

Know what your food actually costs
Reducing beats offsetting, and food is the lever most people can move fastest. We publish the measured footprint of 672 products, each broken down by supply-chain stage — and for 370 of them, how much the production method alone changes the number.

A serial number, not a certificate of vibes
When your credits are retired they are struck off a public registry so nobody can sell them again. Your dashboard shows the exact serial range and links straight to the registry — the same record an auditor would read.
