Without flying, it is Copenhagen, Denmark, 13.6 h of sun a day, about 14h 36m each way by train, for about 14× less carbon (25.7 kg CO₂e return against 362 kg).
The 10 sunniest places within 15 hours of Vienna
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 Vienna in June within 15 hours is Helsinki, 16.0 h, costing 362 kg CO₂e return. The lowest-carbon option is Olomouc at 4.9 kg — 74× less carbon, for 3.5 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 Stockholm can only be reached by air — 312 kg CO₂e, in 5h 12m. Allow up to 24 hours and the train does the same journey for 36.6 kg in 20h — 9× less carbon for 14h 48m 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 Trelleborg (24.4 kg, 13.9 h) to Linköping (286 kg, 14.7 h) buys 0.8 hours more sunshine for an extra 261 kg — 327 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.

Questions
Where is the sunniest place to go from Vienna in June?
Helsinki, Finland, at 16.0 h. Reaching it emits 362 kg CO₂e return, travelling 5h 24m each way by air (modelled).
Can I get somewhere sunny from Vienna in June without flying?
Yes. Trelleborg reaches 13.9 h and is reachable by rail or ferry in 14h (modelled), emitting 24.4 kg CO₂e return — though Helsinki is sunnier still, if you fly.
How much carbon does a return trip from Vienna to Helsinki produce?
362 kg CO₂e for one person, return, by air. That uses the UK Government's 2026 conversion factors, including radiative forcing for flights.
Carbon uses UK Government (DESNZ/DEFRA) 2026 conversion factors applied to great-circle distance, with radiative forcing included for flights. Rail journey times are modelled estimates, not timetabled services. Full method · download the data.
