The 10 sunniest places within 15 hours of Milan
Ranked on sunshine in May 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.

The low-carbon trade-off
The sunniest place you can reach from Milan in May within 15 hours is Örnsköldsvik, 15.1 h, costing 521 kg CO₂e return. The lowest-carbon option is Carpi at 4.5 kg — 116× less carbon, for 5.2 hours less sunshine.
Every destination here is on the efficiency frontier: nowhere else this site covers is both sunnier in May 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 Świnoujście can only be reached by air — 253 kg CO₂e, in 4h 48m. Allow up to 24 hours and the train does the same journey for 29.7 kg in 16h 30m — 9× less carbon for 11h 42m 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 Lleida (24.0 kg, 13.0 h) to Świnoujście (253 kg, 13.2 h) buys 0.2 hours more sunshine for an extra 229 kg — 1146 kg of CO₂e per hour. That single step is the most expensive sunshine on the whole curve.

May 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.
