[Transition of Food Consumption Patterns and Carbon Footprint of Urban and Rural Residents in China].

The food system is an important source of greenhouse gas emissions, and the carbon footprint analysis of food consumption under the dual carbon background is of great significance for the sustainable development of the food system. To reveal the differences in food consumption patterns and carbon footprints between urban and rural residents in China, the life cycle carbon emission coefficient method was used to measure the direct carbon emissions of food consumption by urban and rural residents in China from 2000 to 2021. From the perspective of carbon footprint composition, the following main conclusions were drawn： ① The structure of food consumption among residents in China shifted from predominantly plant-based to a balanced consumption of both plant- and animal-based foods, reducing the disparity in various food consumption quantities between urban and rural residents.
