​
Response

The response contains the full step-by-step calculation breakdown as used by the Dcycle kernel. The exact shape reflects the kernel’s multi-DB calculation result for the DEFRA hotel room-night activity.

​
Calculation Methodology

CO2e is computed as: 
CO2e (kg) = rooms × nights × EF (kg CO2e / room-night)
Where:
  • nights = check_out_date − check_in_date in days
  • EF = DEFRA hotel room-night emission factor for the stay’s country (from the defra_hotel_stays kernel activity, HOTEL_STAYS category)
One total_impacts row is written per night so that partial-period exports and dashboards pro-rate correctly.
