FAQ

Questions merchants ask us

Do you process payments directly?

Green Cart Pass tracks the offset option a shopper chooses and the pledge it creates. In production, the contribution amount is added to the order and settled through your existing payment processor — we don't hold funds ourselves.

Which offset providers do you work with?

Merchants can list options for reforestation, renewable energy credits, verified carbon credits, and ocean plastic cleanup, each backed by a project of your choosing.

How long does integration take?

Most merchants are live the same day: create an account, add your first offset option, and it's ready to appear at checkout.

Can I change pricing later?

Yes — edit the price, impact unit, or status of any offset option at any time from your dashboard.
