According to the Daily Telegraph of Britain, in order to change the consumption concept of British people and buy "low-carbon" food, the British government plans to label supermarket food with "carbon footprint", so that consumers can clearly understand their carbon dioxide emissions while shopping for food and adopt green shopping behavior.

The carbon footprint of a product refers to the direct or indirect greenhouse gas emissions of the product from raw material acquisition, manufacturing, packaging, transportation, waste to recycling. The carbon label is to label the carbon footprint of the product on the commodity. Hilary Benn, director of the UK Environment Agency, said that in the future, people will eat less "carbon intensive" food such as red meat, such as beef and mutton, and buy less food with too much packaging. This will encourage manufacturers to produce more "low-carbon" food and ensure that the UK achieves the goal of carbon saving and emission reduction. In order to help consumers actively participate in national emission reduction activities, the new "green" food will mark how much carbon dioxide the product releases during production, packaging and transportation. Hillary Benn said in her speech at the Oxford Agricultural Conference: "Choosing low-carbon goods will help people cope with climate change. In the next few years, we may learn more about the impact of food production on the environment. We are still learning how to do better, and fight with other countries to control carbon emissions. Consumers' choices are crucial."

It is reported that Tesco, Pepsi Cola and other top brand food companies in the UK have labeled some foods with "carbon footprint" to help consumers make "green" purchasing decisions.. As part of the UK's food production strategy in the next 20 years, the government calls on other brands of food to be labeled with "carbon footprint", so that consumers who buy these goods can clearly see the amount of carbon dioxide emitted during the process from the beginning of processing to putting on the shelves. After entering the supermarket, consumers can check the "carbon footprint" label of goods according to their own environmental protection concept and adopt green shopping behavior.

The carbon saving fund, an organization supported by the government, is currently cooperating with food enterprises to help manufacturers label different types of products with "carbon footprint". The Carbon Trust is a public welfare organization in the UK. Its purpose is to help enterprises in all walks of life achieve carbon saving and emission reduction, thus promoting environmental protection.

Following the Irish tainted pork scandal, Hillary Benn also called on all meat processors to label pork with a "carbon footprint" label, which some said would be implemented next month. But environmental groups say the government needs to enact laws, not just call on food companies to do so. Actress and food activist Tracy Worcester said: "This must be mandatory, because no manufacturer does not want people to buy their products." Helen Riemer of Friends of the Earth also said that the "carbon footprint" label is helpful for coping with climate change, but more important is to produce more low-carbon products. The government should support sustainable organic agriculture and reduce subsidies to factory farms.

Research results released at the recent Oxford Agricultural Conference show that farmers generally support GM crops. John Beddington, the government's chief scientific adviser, said that he would invest more money in this research and use more environmentally friendly methods to increase food production.
