Holidaymakers are being shown how many trees they would need to plant to offset flight carbon emissions.

The analysis by freight firm 1st Move International found an 826-mile return flight between Edinburgh and Amsterdam would require one tree, compared to 19 for a 12,400-mile round trip to Ko Samui or Phuket in Thailand.

The company said it would cost between around £6 and £15 to plant each tree.

However, Friends of the Earth Scotland (FoES) said most tree-planting schemes lacked credibility and people should fly less instead.

A separate survey showed the proportion of people who thought the pros of aviation outweighed the cons has fallen from 72 per cent to 67 per cent since last year.

Air traffic control firm Nats and research consultancy Savanta ComRes, which commissioned the poll, said: “It may be linked to people’s increasing concerns about air and noise pollution, and reflects the public’s growing environmental consciousness”.

However, the survey also showed only 37 per cent would be willing to paying an environmental levy for their flights.

Among the other most popular destinations from the UK, a 2,340-mile return trip from Edinburgh to Mallorca would require four trees and a 4,060-mile round trip to Tenerife would need six trees.
