New emission factor pages for Australia, Canada, New Zealand, the US and hotel stays in 37 countries

Since 19 October 2026, Carbon Recycling's free emission factor library has 97 new pages: hotel stay factors for 29 more countries (37 in all), and official government factors for Australia, Canada, New Zealand and US fuels and travel. Each page names its source and licence.

Updated 20 October 2026 by the Carbon Recycling team. Figures use the official UK government conversion factors and are checked against the current gov.uk guidance.

The pages are for UK firms with sites, staff or travel abroad, and for businesses based in these countries that want their own government's figures in one place. Every number is read from the government's published file, and each page shows the edition, the licence and how to credit it.

What's new

Hotel stays in 37 countries. 29 more countries, from Japan and India to Brazil and South Africa, using the DESNZ 2026 hotel factors (kg CO2e per room per night). They sit together under "Hotel stays by country" on emission factors, for example Japan hotel stay.
Australia. Electricity for every state and territory grid and the national figure, the residual mix, and natural gas, diesel, petrol and LPG, from the NGA Factors 2022 to 2026 editions published by DCCEEW (CC BY 4.0).
Canada. Electricity intensity for all 13 provinces and territories, 1990 to 2024, from Environment and Climate Change Canada's National Inventory Report (Open Government Licence, Canada).
New Zealand. 16 pages covering electricity, fuels, flights, taxis, public transport, road freight, waste, water and working from home, from the Ministry for the Environment's 2026 factors (CC BY 4.0).
US fuels and travel.22 pages: fuels, steam and heat (8), cars and light trucks (2), business travel and commuting (8) and freight (4), from the GHG Emission Factors Hub (the US EPA 2023 to 2025 editions and the 2026 Cornerstone edition; public domain and CC BY 4.0). US electricity by power region was already covered.

How to use them

Find the activity, multiply your quantity by the factor shown, and note the source and year from the page in your methodology. Each page has a worked example to follow. For electricity in other countries, see electricity factors by country.

How Carbon Recycling helps

In the app, choose the country when you enter hotel nights and the right DESNZ factor is applied. On Enterprise, sites outside the UK use their own country's electricity factor; our post on official government electricity factors lists which countries use a government figure, and hotel stay emissions explains how to report business travel stays.

Frequently asked questions

Are these pages free to use?

Yes. Every page is free to read with no sign-up. Each one names the government source, the edition and the licence, so you can cite the original publisher in your own report.

Should a UK company use these factors in its SECR report?

For UK sites and UK activity, keep using the DESNZ conversion factors. These pages are for activity abroad: a site in Australia or Canada, a team in New Zealand or the US, or staff staying in hotels overseas. The GHG Protocol asks you to use factors that match where the activity happened.

Does the Carbon Recycling app use these factors?

Hotel nights in the app already use the DESNZ factor for the country you pick. Electricity at an overseas site uses that country's grid figure, including the official Australian, Canadian and New Zealand ones. The other Australian, Canadian, New Zealand and US pages are reference data for now: read the figure and its source from the page.

Why does a hotel night have a different factor in each country?

A hotel's emissions depend mostly on the local electricity grid and how much heating or cooling it needs, so DESNZ publishes a separate figure per country.

New free tool: do you need to register for the UK CBAM?
Up to four questions about your imports tell you whether you must register for the UK CBAM, from when, and your first deadlines.
Market-based Scope 2 now uses the UK residual fuel mix
With no green tariff or supplier figure, market-based Scope 2 now uses the DESNZ residual mix instead of copying the grid average.
Official government electricity factors for seven countries
Sites in Australia, Canada, China, France, Germany, New Zealand and Singapore now use their government's own grid factor where it is current.
