Scarcity of water and emissions of greenhouse gases (GHGs) are the two key environmental issues for crop production in India. Reduction of carbon footprint (CF) and water footprint (WF) from crop production can help to address the environmental hazards created from scarcity of water and GHG emissions. The CF and WF of rice, wheat and maize were estimated for the year of 2014 under Indian conditions based upon the national statistics and other data sources. Total carbon footprints (TCFs) of rice, wheat and maize in India were estimated to be 2.44, 1.27 and 0.80 t CO2 e ha-1 respectively and product WFs for rice, wheat and maize in India were 3.52 m3 kg-1, 1.59 m3 kg-1 and 2.06 m3 kg-1, respectively. Blue WF was found highest in West India (WI) for rice and South India (SI) for both wheat and maize because of the highest irrigation water use in those regions. There was a positive relationship between the CF and WF, hence mitigation of both is possible simultaneously in various regions of India. The potential measures for mitigating GHG emissions and optimal use of water for rice, wheat and maize production in India are recommended in this paper.
