Hotel stays footprint
This hotel carbon calculator measures the CO2e of your hotel stays using the DESNZ 2026 per-room-night factors, which cover the UK and around 38 other countries. A night in a UK hotel averages 10.4 kgCO2e in the 2026 factor set; the figure varies by country with the local electricity grid.
TL;DR — Enter nights per country; we multiply by the official DESNZ 2026 per-room-night factor for that country — UK: 10.4 kgCO2e per night.

How is it calculated?
- Per-country room-night factors from DESNZ 2026 (UK plus ~38 countries).
- Each stay is nights × the destination country's factor — no modelling assumptions of ours on top.
Every calculation runs server-side against a versioned official factor set and records the factor behind each line — see our methodology.
Frequently asked questions
- What is the carbon footprint of a hotel night?
- In the UK, 10.4 kgCO2e per room-night per the DESNZ 2026 factors. Other countries differ mainly with the carbon intensity of their electricity grid.
