Each part of the car carries an on-chain passport: where it came from and the carbon footprint to make it and bring it to the circuit.
The embodied footprint is manufacturing plus inbound transport of the car's parts (cradle-to-gate). It is a separate account from the race-weekend footprint and is never added to it.
Tracked means a passport exists and the footprint is recorded. Matched on-chain means that footprint has been matched by carbon credits and removals retired on-chain. The car as a whole is not implied neutralised.
