Which fruits and vegetables are hardest on the climate?
Besvaret 1. november 2026
No fruit or vegetable in my sources comes close to Danish beef per kilo. The heaviest are produce from heated greenhouses and goods flown in. DTU Fødevareinstituttet, in the scientific basis for the Danish dietary guidelines, writes that field-grown vegetables and Danish fruit such as apples and pears are low, while fruit and vegetables shipped by air are higher. A British study of 56 vegetables, described in a Danish paper, found asparagus had the highest footprint per kilo, because much of it was flown in. Tomatoes from Dutch greenhouses came to 2.05 kg CO2e per kg in a Swedish shop against 0.45 kg from Spanish greenhouses, according to a review from Aarhus University. For comparison, minced beef comes to 45.47 to 50.61 kg per kg in CONCITO's Danish climate database, and avocado to 1.22 kg. CONCITO is a green think tank. My sources have no full ranking of fruit and vegetables.
