What proportion of global emissions does aviation cause?
Budget airlines have made travel affordable for millions, but the price on the ticket hides other costs. Aviation accounts for around two to three percent of global carbon emissions, and the number of flights is expected to rise. Some economists argue that fares should include the environmental damage caused, which would make short-haul flights far more expensive. Airlines respond that new engines and alternative fuels will soon cut emissions, but critics say these technologies are many years from widespread use. Meanwhile, a small but growing number of travellers are choosing to holiday closer to home, calling it 'staycation tourism'.
