• Rice–wheat is the leading double-cropping system in Asian subtropical countries, and the management of rice straw after harvesting with combine harvesters is a major problem. With increasing attention being placed on mitigating global warming and achieving sustainable agricultural intensification, we estimate carbon sequestration and greenhouse gas (GHG) emissions associated with the adoption of various straw management practices, to incentivize farmers based on carbon credits. The total cost involved with the adoption of straw management practices including losses in productivity was in the range of Rs. 5500–14,866/ha when straw was incorporated in the soil. Total carbon credited either sequestered in soils or as GHG emissions varied from a minimum of − 0.97 t CO 2 eq/ha, when paddy straw was partially burnt, to a maximum of 5.17 t CO 2 eq/ha, when straw was kept as mulch with minimum cost involved in managing the straw. Hence, mulching of straw using zero or minimum tillage practices has the least global warming potential and should be promoted for the management of straw in the rice–wheat cropping system.
