Staying there

A hotel room in United Kingdom emits about 10.4 kg CO₂e per night under UK Government 2026 factors — a country average per occupied room, not this or any particular hotel. 7 nights in one room adds roughly 73 kg — about 5.6× the carbon of one person getting there by rail from Southampton. Two sharing the room halve that share each; the journey does not halve.
