The entire food production chain – from production to consumption – is closely related to climate change. On the one hand, agricultural production and animal husbandry are under threat from climate change. Changes in temperature and precipitation brought about by global warming and the frequent occurrence of extreme weather have an impact on agricultural production, grassland yield and livestock carrying capacity. On the other hand, all aspects of food production and consumption, such as food production, processing, transportation, and kitchen waste disposal, are significant sources of greenhouse gas emissions. iGDP contributes to China’s 2060 carbon neutrality goal by identifying the opportunities for greenhouse gas emission reduction in the entire food production and consumption chain, promoting actions to drive down emissions in this sector and develop sustainable agriculture and food system practices.
