Flight cuts urged 'for climate's sake'
![]() Flying is becoming more fuel-efficient
By environment correspondent Alex Kirby
Several environmental campaign groups are urging people to take fewer flights for the sake of the global climate. They say aircraft emit more of the main greenhouse gas than cars for each passenger they carry. The groups say that, per passenger, one return flight from the United Kingdom to Florida produces as much carbon dioxide (CO2) as a year's driving by the average British motorist. And they say commercial jets add almost as much to global warming annually as the whole of Africa. The groups are Friends of the Earth, the Aviation Environment Federation, the National Society for Clean Air, and the Heathrow Association for the Control of Aircraft Noise. In a report, Aviation and Global Climate Change, they say:
It also recommends taking trains instead of using aircraft for short distances, and says teleconferencing could replace inessential business flights. Hugh Somerville, of British Airways, said he thought the report's figures on aircraft fuel efficiency were "a gross overestimate". Efficiency doubled He told BBC News Online: "The fuel efficiency of our fleet has doubled in the last 20 to 25 years, and we are getting results which produce about 30% or 40% of the CO2 the report mentions. "Nevertheless, we take this problem very seriously, and we share the groups' concerns.
"We are sponsoring a study on emissions trading, which we think will probably be the best way to deliver improvements by aviation.
Some scientists remain unconvinced of the reality and urgency of climate change, and say our understanding of climate processes is still very limited. Awaiting proof They believe the evidence that human activities are inducing rapid change is weak. They highlight the inconsistencies between the temperature records taken at the Earth's surface, which show rapid warming over the last two decades, and the data produced by satellite and balloon studies. These show little or no warming higher in the atmosphere over the same period.
