Eco rules for places

EcoProof is for places that really are eco. A place can only join if it agrees to these rules:

• We do not serve drinks in single-use plastic (cups, lids or bottles we hand out).
• We do not give out plastic straws, plastic cutlery or single-use plastic takeaway containers.
• We are genuinely eco-minded, not just using the label.

Eco shops also agree not to hand out single-use plastic bags, or pack online orders in single-use plastic, where an alternative exists.

Who checks?

Joining is a promise: owners confirm the rules when they set up their place. We don't inspect places in person yet, so we rely on customers to tell us when a place doesn't keep it. “Verified” on the map means claimed and set up on EcoProof, not independently audited. Real vetting is on our roadmap.

Eco stars

Cafés, restaurants and hotels get up to five eco stars, in half stars. The owner answers a checklist of practices a visitor can see for themselves, such as real cups for dine-in or no plastic water bottles. Each practice is worth points, out of 100.

Some practices don't exist at every place, like takeaway at a café that has none. Those can be marked not applicable: they are left out, and the score is worked out from the practices that do apply. Eco shops, in store or online, are listed without stars: they show the plastic and CO₂ their customers save instead.

The owner's answers only count once they are published. Publishing is a public declaration: a fingerprint of the answers is written to the Solana blockchain, so what was declared, and when, can never be changed quietly. An owner can publish a new declaration at most once a day; earlier ones stay on record on the place's page.

• Listed: 0 to 19 points
• 1 star: 20 to 29 points
• 1.5 stars: 30 to 39 points
• 2 stars: 40 to 47 points
• 2.5 stars: 48 to 54 points
• 3 stars: 55 to 62 points
• 3.5 stars: 63 to 69 points
• 4 stars: 70 to 77 points
• 4.5 stars: 78 to 84 points
• 5 stars: 85 to 100 points

Report a place

If a place doesn't keep these rules, open it on the map and tap Report this place. You choose a reason and can add a note. Reports from people who have collected a stamp at the place count most, because they have been there.

• When 3 different customers who have a stamp there report a place within 30 days, it is paused: hidden from the map and no new stamps, until we have looked at it.
• We then either restore the place or remove it. Stamps already collected stay in passports and their Solana proofs are untouched.
• One report per person per place every 30 days. Owners and staff can't report their own place. Your report is never shown to the place.

Reports are reviewed by people, and we can get it wrong. If your place was paused and you think that's a mistake, contact us and we'll look again.
