Of the 2,000 adults surveyed between 25-28 July, only 43% said they were concerned about what effect their travel choices were having on the environment. 

According to the study, men are more likely to be unconcerned by their holiday’s carbon footprint than women (59% vs 54%), while younger adults are more likely to be more anxious about the planet than older travellers. 

Three out of five (59%) 18- to 24-year-olds said they were worried, compared with just a third (34%) of over 65s, claimed research from No 1 Currency. 

Simon Phillips, managing director at No1 Currency, said: “The government must work harder to get its climate change message across to holidaymakers, and it clearly needs to do more to help travellers better understand their carbon footprint as they finally get to take a break.

“Our data confirms how most people like to unwind while on holiday. And for many, ‘getting away from it all’ also means forgetting all the troubles of the world. But they may not be fully aware of the carbon cost of their holiday.”
