Work out your hong Kong hotel stay emissions
= 1.03 tonnes CO2e in 2026 (Scope 3)
Each room night × 51.500 kg CO2e, the 2026 UK government (DESNZ) factor.
That is one line of your footprint. Want the whole thing done for you?

Hong Kong hotel stay emission factor by year
| Year | Scope 3 (kg CO2e per room night) | Change |
|---|---|---|
| 2026 | 51.500 | 0.0% |
| 2025 | 51.500 | 0.0% |
| 2024 | 51.500 | 0.0% |

| 2022 | 51.500 | -21.9% |
| 2021 | 65.900 | – |
Total kg CO2e for the seven greenhouse gases, from the official DESNZ files for each year. 2026 factor ID: 29_600_4019_13_1. Where a factor jumps sharply between two years, it is usually because DESNZ changed its method or data source, not because the activity itself changed.
Worked example
Take 20 hotel nights a year for staff visiting customers in Hong Kong. 20 room nights × 51.500 kg CO2e = 1.03 tonnes CO2e, reported as Scope 3, category 6 (business travel).
How to report it
Hotel stays are Scope 3 category 6, business travel. The government publishes a factor for each country because a hotel's emissions depend mostly on the local electricity grid and how much heating or cooling it needs.
Count room nights, not people: two colleagues sharing a room is one room night. Record each country separately so the right factor is used.
Where the data comes from
You'll usually find it in your booking system or expenses, as the number of room nights in each country. Keep the source documents: anyone checking your Carbon Reduction Plan or SECR report may ask how each figure was worked out.

Most of a hotel's footprint is the electricity it uses, so the country's grid matters most. Hong Kong's grid averaged 675 g CO2e per kWh in 2024: see the Hong Kong electricity emission factor.
