Staying there

A hotel room in Portugal emits about 19 kg CO₂e per night under UK Government 2026 factors, so a week adds roughly 133 kg — about 20.5× the carbon of getting there by rail from Lisbon.

How busy it gets

Algarve records 46.6 overnight stays per resident a year (22,941,654 nights in 2025). That is heavy tourist pressure — among the densest in Europe.

Eurostat, nights spent at tourist accommodation by NUTS 3 region, against resident population. Shown for context only — it plays no part in which destinations appear or in what order. Eurostat does not cover the United Kingdom after 2016, nor North Africa or the Levant at all, so this figure is absent for roughly a third of the destinations here.
