Staying there

A hotel room in Germany emits about 13.2 kg CO₂e per night under UK Government 2026 factors, so a week adds roughly 92 kg — about 20.1× the carbon of getting there by rail from Zurich.

How busy it gets

Ulm, Stadtkreis records 6.6 overnight stays per resident a year (853,057 nights in 2024). Comparatively quiet by European standards.

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.
