How rewards work
You buy protein, the app pays for the carbon you did
not emit. Lower-carbon protein is worth more per gram.

Claiming
- Scan the product barcode with the camera, then photograph your
receipt.
- Paper or digital. A till receipt, or the order page from a pickup
or delivery shop — photograph the screen, or choose a saved screenshot.
What the food is worth
Every rate is the reference footprint divided by that food’s, so a
cleaner protein earns more for the same gram.
How this is calculated →
| Protein source | kg CO₂e | rate |
|---|
Boosts
- Hold an NFT and every claim is multiplied. —
- Only the highest applies — they do not add up.
- Held 72 hours before you shopped, or it does
not count for that receipt. An NFT bought after the shop cannot boost it.
Voting
- Vote for Per Gram in a VeBetterDAO allocation round so we can
give you more rewards.
Limits
- 800g of protein a week. Above that, a claim
is scaled down rather than refused.
- Claim within 3 days of the date on the
receipt.
- One receipt, once. A copy of a receipt somebody already claimed is
refused, whoever is holding it.
