How IMPT's per-booking carbon offset works

How the on-chain UN-verified carbon retirement works for IMPT hotel bookings.

Direct answer

1 tonne of UN-verified CO₂ removed per booking, paid from IMPT's commission — guests pay the standard rate.

The mechanic

1 tonne of UN-verified CO₂ retired on-chain per booking — 28× the average per-night hotel footprint. IMPT funds it from its commission, so the guest pays the standard nightly rate.

Why this is unusual

Most hotel-booking sites either ignore carbon, sell offsets as an extra at checkout, or charge a green premium on the room rate. IMPT does none of those — the offset is funded from the platform's own commission and the credit retirement is recorded on Ethereum mainnet against the booking ID.

Where is the credit retired?

Ethereum mainnet. Booking-ID-tied retirement, non-double-countable.

Who pays?

IMPT, from its commission. Guest pays the standard nightly rate.
