At the 28th Conference of the Contract Congress (COP28) held in the United Nations Climate Change Framework Convention in Dubai,exclusive information the United Arab Emirates, 134 countries signed a declaration in 134 countries, promising to reduce food production and consumer greenhouse gasemission.
This is the first time in the nearly 30 years of climate summit to recognize the importance of the grain system in this way.In addition, on December 10, the COP28 first discussed the method of reducing food and agricultural emissions for the first time.
Many people welcome these measures.Clement Metivier, an expert in the British World Natural Foundation, who is participating in COP28, pointed out that the momentum of transition around the grain system to respond to biological diversity and climate crisis is indeed growing.But at the same time, researchers pointed out that as one of the largest and basically unresolved emissions sources in the world, the grain system does not do enough in emission reduction, which involves some difficult political decisions.
Improve the sustainability of the grain system is essential for achieving the "Paris Agreement" goal.According to a research by the Italian European Commission Joint Research Center in 2021, food emissions from farms to tables account for about 1/3 of global greenhouse gas emissions.Researchers estimate that in 2015, about 70%of these emissions came from changes in agricultural and land use, such as cutting trees and using land as farmland.
A study published in Nanyang University of Science and Technology in Singapore showed that about half of the emissions of food system emissions came from food that lost or wasted in the supply chain before reaching the consumer.The team estimates that the reduction of grain loss and waste can reduce the sedimental gas emissions of about 1/4 of the grain system.
The "Declaration on the Tough Food System, Sustainable Agriculture and Climate Action" signed on December 1 means that countries need to include food and agriculture into the next round of emission reduction plans, that is, the country's independent contribution (NDCS).This represents the commitment made by countries to realize the Paris Agreement.
However, the declaration has no legal binding power, nor does it mention the role of fossil fuels in the food system, such as fossil fuels used to transport food and provide power for agricultural machinery and refrigeration.In addition, at the end of the COP28, all countries must reach an consistent draft text without mentioning the grain system."This is an obvious omission." Metivier hoped that this would be corrected in the final version.
"This is at least a highest -level commitment, said the non -governmental organization's third world network biological diversity and agricultural researcher, said," this is at least a highest -level commitment. We need to gradually eliminate fossil fuels into the revision of the national climate commitment. "
Perhaps the most controversial aspects of food emissions are related to diet.Meat, dairy products and other animal products have more emissions from other foods such as fruits and vegetables.
Helen Harwatt, a researcher at the Food System of the Chartham Research Institute in London, England, said that in high consumer countries, reducing the consumption of animal products will produce the maximum effect in the short term, which should become a preferred option.She added that this transition object should include countries that seriously depend on animal husbandry, such as India and African countries.According to an analysis of the "climate policy initiative" of the think tank, only 4%of global climate financing flows to the grain system.
But it is complicated to change people's diet worldwide globally.Patty FONG, director of the Global Food Future Alliance Project, also participated in COP28. She believes that achieving these goals requires complex political decisions.
The government usually believes that it is necessary to provide safe and nutritious foods and economic growth, which means that the industrialized food production is given priority.However, Li Ching pointed out that this approach may not pay much attention to environmental impact.Some large companies, including fossil fuel companies, have a good relationship with the government, which can promote the implementation of grain system emission reduction measures.Essence
