Portugal hotel night: carbon footprint per room-night
Live factor value
19 kgCO2e per room-night

Portugal's official hotel-night factor — live below — lands mid-table in the DESNZ 2026 country list: noticeably above neighbouring Spain despite similar sunshine, because Portugal still leans on gas-fired generation when wind and hydro run short.
The comparison with Spain is a neat illustration of what the hotel factor really measures: not the hotel's star rating or pool count, but the carbon intensity of the electricity and heat behind each occupied room. As Portugal's renewables build-out continues, expect this factor to fall in future editions.
Worked example
A week's stay in Portugal (7 nights): 7 × 19 = 133 kgCO2e.

- Why is Portugal's factor higher than Spain's?
- Grid mix: Portugal's remaining gas-fired generation keeps its average electricity carbon intensity above Spain's increasingly wind- and solar-heavy grid, and hotel footprints track the grid.
