I used [0] for the carbon calculations of a roundtrip flight. Assume 200 passengers. Flying between Stockholm and Malaga gives us 460 kg of CO2 in total. An average 150 sq meters villa uses about 12500 kWh during October-March, if I take the current CO2-intensity from [1] this gives us about 375 kg of CO2 during these months. This is excluding any calculations to cool the summer house in southern Spain. This calculation would be completely different for Germany right now, which has 10x as much CO2-intensity as the electricity region that Stockholm is a part of. That would be 3,75 tonnes of CO2 during these months. In other words, it's very country dependent. This is also ignoring any different heating modes (heat pump/gas/wood/...) between houses.
