A worldwide shift from current diets to the planetary health diet proposed by the EAT-Lancet Commission would have direct implications for agricultural greenhouse gas (GHG) emissions. By modelling the trajectory of food from cradle to farm gate while accounting for international trade, we estimate that agricultural GHG emissions would decrease in 101 countries as well as globally. Yet, in primarily low- and middle-income countries, agricultural GHG emissions would increase by 12-283%. Country-specific impacts of dietary transitions should be considered in climate change mitigation policy.
从当前饮食模式向EAT-柳叶刀委员会提出的全球健康饮食模式的转变，将对农业温室气体排放产生直接影响。通过在考虑国际贸易的情况下对从源头到农场大门的食物轨迹进行建模，我们估计，101个国家以及全球范围内的农业温室气体排放将会减少。然而，在主要的低收入和中等收入国家，农业温室气体排放将增加12%至283%。在缓解气候变化政策中，应考虑饮食转变对特定国家的影响。
