A Bite of China: Food consumption and carbon emission from 1992 to 2007

In conjunction with the rapid rise in household food expenditures per capita, China's food consumption has increased greatly. At the same time, dietary patterns have changed dramatically, as between 1992 and 2007 China underwent a transition to a more animal-based westernized diet. This rise in food consumption and shift in dietary structure may contribute substantially to climate change. In this paper, an input-output model is used to explore the food-related carbon emissions of Chinese urban households in 1992 and 2007. The results indicate that the physical volume of and economic expenditures on food consumption have increased by 20.7% and 35.9%, respectively. However, food-related carbon emissions per capita in 2007 had decreased nearly 21% compared to emissions in 1992. Based on parametric estimates of environmental Engel Curves and the Oaxaca-Blinder decomposition, the variation in household income may lead to a hypothetical carbon emissions increase of 1.694 tons. However, the improvement in energy use efficiency had offset the impact from income growth and dietary transition and led to the drop in China's food-related carbon emissions from 1992 to 2007.
