The food the world wastes accounts for more greenhouse gas emissions than any country except for China and the United States， the United Nations said in a report entitled The Food Wastage Footprint.

联合国在一份题为《粮食浪费足迹》的报告中称，全球粮食浪费产生的温室气体排放，超过中国和美国以外其他任何国家的排放量。

Every year about a third of all food for human consumption， around 1.3 billion tons， is wasted， along with all the energy， water and chemicals needed to produce it and dispose of it.

全球每年约有1/3的粮食被浪费，浪费量大约为13亿吨。与此同时，生产和处理粮食所需的能源、水和化学制品也被浪费。

“Food wastage reduction would not only avoid pressure on scarce natural resources but also decrease the need to raise food production by 60 percent in order to meet the 2050 population demand，” the FAO said.

“減少食物浪费，不仅能避免因稀缺的自然资源减少产生的压力，还能减轻需要提高粮食生产水平60%才能满足2050年的人口需求的压力。”联合国粮农组织称。

It suggested improving communication between producers and consumers to manage the supply chain more efficiently， as well as investing more in harvesting， cooling and packaging methods.

报告建议加强生产者和消费者之间的沟通，以更有效地管理供应链，以及更多地投资于收割、冷却和包装方法。

It also said consumers in the developed world should be encouraged to serve smaller portions and make more use of leftovers. Businesses should give surplus food to charities， and develop alternatives to dump organic waste in landfill.

该报告还说，应鼓励发达国家的消费者提供小分量的食物，并更多地利用剩余饭菜。企业应该将剩余食物捐给慈善机构，并开发出将有机废物倒入垃圾填埋场的替代方法。

The FAO estimated the cost of the wasted food， excluding fish and seafood， is about $750 billion a year， based on producer prices.

联合国粮农组织估算，基于生产者价格，不包括鱼和海鲜在内，一年所浪费粮食的经济损失约为7500亿美元。
