Why can "eating on the ground" save the earth? Study reveals: nearly 20% of food carbon emissions come from transportation In the past, when it comes to the impact of diet on climate change, the first thing that often comes to mind is animal husbandry and agriculture, but according to the latest research in June 2022, food transportation accounts for about 50% of the greenhouse gas emissions generated by the global food system. Accounting for 20% of them, the study calls on the public to adopt local diets as much as possible to reduce greenhouse gas emissions caused by food transportation. In the past, when it came to the impact of diet on climate change, most of the focus was on the carbon emissions of agriculture and animal husbandry, but in fact, according to the latest research "Global food-miles account for nearly 20" published in the international journal "nature food" in June 2022 % of total food-systems emissions” pointed out that the global food system accounts for about 30% of the total greenhouse gas emissions generated by humans, of which food transportation accounts for about 20%, about 6% of total carbon emissions, and food Transportation emissions account for about 50% of carbon emissions from road vehicles, which shows that carbon emissions caused by food transportation are in urgent need of improvement. Food transportation accounts for 6% of greenhouse gas emissions, and vegetable and fruit transportation accounts for 1/3 of them The study surveyed 74 countries including China, the United States, Russia, India, Germany, France, Japan and other 37 industries including animal husbandry, manufacturing, etc. In addition to finding that food transportation accounted for 37% of the total greenhouse gas emissions generated by human behavior. In addition to 6%, these emissions were observed to be concentrated in 4 countries, China, the United States, Russia and India being the largest food transport emitters, accounting for 46% of transport emissions and only 12.5% of the global population. Study lead author Mengyu Li, a professor at the University of Sydney, said transport emissions also depended on the type of food. For example, transporting fruits and vegetables produces almost twice as many emissions as the production process, which together account for more than one-third of food transport emissions. “Because vegetables and fruits need to be transported in a temperature-controlled manner, food mileage emissions are higher,” Mengyu Li said. In fact, according to the study, the carbon emissions from food transportation are seven times higher than previously estimated, and far exceed the transportation emissions of other commodities, such as industrial transportation, which accounts for only 7 percent of emissions. Eating locally and cultivating sustainable eating habits are the keys to mitigating climate change In this regard, the study calls on consumers to "eat locally", and the latest report released by the United Nations Intergovernmental Panel on Climate Change (IPCC) in April 2022 also calls for an immediate reduction in global emissions, To avoid exceeding the Paris Agreement target of 1.5°C away from global pre-industrial levels. At the same time, the researchers calculated that if the global population were to eat locally, daily greenhouse gas emissions would be reduced by 38 million tons, the equivalent of driving a one-ton car from Earth to the sun 6,000 times back and forth. Although the research team admits that it is impractical to adopt a completely local diet, consumers' attitudes and consumption behaviors towards sustainable diets can still maximize climate change improvement. In addition, the carbon emissions of transporting food can also be reduced by adopting clean energy transportation. . "Just like we've done for most of the species' history: eating local, seasonal foods will help provide a healthy planet for future generations," said study co-author Professor David Raubenheimer.
