“People should have one meat-free day a week if they want to make a personal and effective sacrifice that would help deal with climate change,” the world’s leading authority on global warming has told The Observer.
Dr Rajendra Pachauri, chair of the United Nations Intergovernmental Panel on Climate Change, said that people should then go on to reduce their meat consumption even further.
Pachauri, who was re-elected the panel’s chairman for a second six-year term last week, said diet change was important because of the huge greenhouse gas emissions (排放) and other environmental problems associated with raising cattle and other animals. “It was relatively easy to change eating habits compared to changing means of transport,” he said.
The UN’s Food and Agriculture Organisation has estimated that meat production accounts for nearly a fifth of global greenhouse gas emissions. These are produced during the production. For example, ruminants (反刍动物), particularly cows, give off a gas called methane, which is 23 times more effective as a global warming agent than CO2.
Pachauri can expect some opposite responses from the food industry to his advice, though last night he was given unexpected support by Masterchef presenter and restaurateur John Torode. “I have a little bit and enjoy it,” said Torode. “Too much for any person is bad. But there’s a bigger issue here: where the meat comes from. If we all bought British and stopped buying imported food, we’d save a huge amount of carbon emissions.”
Professor Robert Watson, the chief scientific adviser for the Department for Environment Food and Rural Affairs, said government could help educate people about the benefits of eating less meat, but it should not regulate. “Eating less meat would help, there’s no question about that,” Watson said.
However, Chris Lamb, head of marketing for pig industry group BPEX, said the meat industry had been unfairly targeted and was working hard to find out which activities had the biggest environmental impact and reduce them. “Some ideas were contradictory,” he said. “For example, one solution to emissions from cattle and other animals was to keep them indoors, but this would damage animal welfare. Climate change is a very young science and our view is there are a lot of simple solutions being proposed.”
