About Hotel Stay and Business Travel Carbon Calculator
Free accommodation estimator: destination grid, hotel class and room nights into Scope 3 Category 6 kg CO2e. For travel coordinators. No signup.
The forgotten travel emission
Flight calculators are everywhere, but a week in a luxury resort on a fossil grid can add 300+ kg CO2e nobody budgets. Accommodation is Scope 3 Category 6 and belongs in every trip total.
Class and grid multiply
Budget rooms run near 8 kg per night against 35 for luxury, scaled by regional grid intensity. Region choice can matter as much as star rating.
