This study examines the economics of using crop residues to replace coal burning for energy in China in order to mitigate carbon emissions. About 60 per cent of the available crop residues are now used by rural households in China to replace coal so that the residues are already making a major contribution to controlling China's potential carbon emissions. Using the crop residues more efficiently in village or centralized facilities, shifting to crops with more residues, or growing energy crops can all further reduce carbon emissions. However, accounting for the costs of collecting, transporting, drying and storing crop residues and the foregone crop revenue, the study estimates that the marginal cost to remove more carbon emissions with crop residues will be high.
