Turn every checkout into a credible carbon-neutral option backed by methane-abatement credits.
Ch4mber credits are tied to orphan-well methane abatement projects. Shoppers opt in, merchants stay in control, and orders are only marked carbon neutral once retirement evidence is completed.
1) Customer Opt-in
Give buyers a clear optional contribution at product/cart, not an automatic surcharge.
2) Issued-credit Gate
Every order checks available issued inventory before claimable status can be shown.
3) Retirement Proof
Queue, completion, and evidence references are tracked per order for auditability.
