Overweight people eat more than thin people and are more likely to travel by car, making excess body weight doubly bad for the environment, a new UK study has found.
“When it comes to food consumption, moving about in a heavy body is like driving around in a gas guzzler,” researchers Phil Edwards and Ian Roberts wrote in their study published in the International Journal of Epidemiology.
They also say food production is a major source of greenhouse gases.
“We need to be doing a lot more to reverse the global trend towards fatness, and recognise it as a key factor in the battle to reduce [carbon] emissions and slow climate change,” the British scientists, from the London School of Hygiene and Tropical Medicine, said in the study .
They estimated that each fat person is responsible for about one tonne of carbon dioxide emissions a year more on average than each thin person, adding up to an extra one billion tonnes of CO2 a year in a population of one billion overweight people.
The European Union estimates each EU citizen accounts for 11 tonnes of greenhouse gas emissions a year.
