The 10 sunniest places within 15 hours of Zurich
Ranked on sunshine in June alone, among well-known places (a Wikivoyage travel guide and at least 40,000 Wikipedia readers a year), one per area and at most three per country. The carbon is shown, not used to choose: the list further down is the other question, how much sunshine each extra kilogram buys.

≈ is the model's estimate (air times include getting to and through the airport); ✓ is a rail journey checked against a real timetable, with the date it was checked. Temperatures are historical daily means for 2023–2024, averaged across day and night, so afternoons run warmer.
The low-carbon trade-off
The sunniest place you can reach from Zurich in June within 15 hours is Kotka, 16.1 h, costing 472 kg CO₂e return. The lowest-carbon option is Lugano at 4.5 kg — 105× less carbon, for 4.3 hours less sunshine.
Every destination here is on the efficiency frontier: nowhere else this site covers is both sunnier in June and lower in carbon. Anything a better option beats outright has been left out.
By rail or ferry By air
What the 15-hour limit costs: at this budget Nyköping can only be reached by air — 348 kg CO₂e, in 5h 18m. Allow up to 24 hours and the train does the same journey for 40.8 kg in 21h 36m — 9× less carbon for 16h 18m more travelling.

Warm is not the same as pleasant, which is why sunshine and rainfall are shown alongside temperature. All three are ERA5 monthly means for 2023–2024.
Where the curve breaks
The frontier is gentle until it isn't. Going from Toulon (15.2 kg, 13.6 h) to Aalborg (272 kg, 14.3 h) buys 0.7 hours more sunshine for an extra 257 kg — 367 kg of CO₂e per hour. That single step is the most expensive sunshine on the whole curve.

June answers differently depending on what you are after, and the lists genuinely diverge: the brightest places are not the hottest, and in summer the useful question stops being where is warm at all.
