Australia hotel night: carbon footprint per room-night
Live factor value
35 kgCO2e per room-night

Australia's hotel-night factor — live below — is more than three times the UK's in the DESNZ 2026 table. Coal still generates a large share of Australian electricity, and hot-climate cooling loads add to every occupied room's energy bill, so the per-night average lands high despite the country's world-class solar resource.
For the classic UK–Australia trip the hotels genuinely add up: three weeks of nights can approach three-quarters of a tonne of CO2e, a meaningful addition even beside the very long flights. Australia's rapid solar and storage build-out should bring the factor down over coming editions.
Worked example
A three-week Australia trip (21 nights): 21 × 35 = 735 kgCO2e.

Frequently asked questions
- Why is Australia's factor so high with all that sunshine?
- Because the grid average still includes a large coal share, and air-conditioning demand is high. Rooftop solar is changing the mix quickly, but the published average lags the transition.
