Staying there

A hotel room in Germany emits about 13.2 kg CO₂e per night under UK Government 2026 factors — a country average per occupied room, not this or any particular hotel. 7 nights in one room adds roughly 92 kg — about 18.5× the carbon of one person getting there by rail from Frankfurt. Two sharing the room halve that share each; the journey does not halve.

How busy it gets

Ilm-Kreis records 3.5 overnight stays per resident a year (369,211 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.

Distances are great-circle. Rail assumes international rail at 0.01135 kg CO₂e per passenger-km with a 1.3× track detour allowance; flights use 0.12576 kg per passenger-km including radiative forcing. Journey times are modelled, not timetabled. Full method.
