The low-carbon trade-off
The warmest place you can reach from Southampton in March within 15 hours is Kom Ombo, 23.6 °C, costing 971 kg CO₂e return. The lowest-carbon option is Exeter at 12.1 kg — 80× less carbon, for 15.6 degrees less warmth.
Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in March 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 Alzira can only be reached by air — 329 kg CO₂e, in 5h 12m. Allow up to 24 hours and the train does the same journey for 49.5 kg in 20h 24m — 7× less carbon for 15h 12m more travelling.

Where the curve breaks
The frontier is gentle until it isn't. Going from Perpignan (38.6 kg, 13.0 °C) to Zaragoza (259 kg, 13.5 °C) buys 0.5 °C more warmth for an extra 220 kg — 440 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

March 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.
