How do I calculate emissions from a hotel's airport or guest shuttle?

If the hotel owns or leases the shuttle and employs the driver, its diesel is Scope 1 at 2.68 kg CO2 per litre. A shuttle supplied with driver by a travel vendor is Scope 3. Divide fuel by transfers to report per guest trip.

Which scope

• Hotel-owned vehicles and drivers: Scope 1.
• Vendor vehicles with drivers, paid by the hotel: Scope 3, Category 1.
• Taxis booked and paid by guests: outside the hotel's inventory.

Data to keep

Fuel invoices or fuel cards per vehicle, and the transfer log with trips and passengers.

Per transfer

Report per transfer, or per passenger if the log records them, and keep it apart from the room footprint.

Worked example: two hotel shuttles (one month, illustrative inputs)

• Diesel: 900 litres x 2.68 = 2,412 kg CO2
• Guest transfers: 1,500
• Per transfer: 2,412 / 1,500 = 1.608 kg CO2

Litres and transfers are illustrative.

What Senseible does here

Senseible reads fuel invoices and fuel card statements (diesel 2.68 and CNG 2.69 kg CO2, IPCC 2006 defaults) into a fingerprinted Scope 1 record. Hired transport goes to the Scope 3 evidence trail, and distance or tonne-km estimates are labelled as estimates.

• Hotel carbon per occupied room
• Business car travel: which scope?
