A piolet survey was conducted in four states of Northern India in Punjab, Haryana, M.P. & U.P. 210 farmers were selected for the study of conservation and traditional farming. Study of data (yield and investment) of rice-wheat crops and transformation carbon emission. Maximum carbon emission during traditional farming was found in UP (290 Kg/C.E./ha), Haryana (288 Kg/CE/ha), Punjab (272 Kg/CE/ha) and MP (130 Kg/CE/ha). Maximum Carbon emission due to chemical (DAP, Urea, insecticide and weedicides) used in traditional farming was found in Punjab (465 Kg/CE/ha), Haryana (150 Kg/CE/ha), Uttar Pradesh (250 Kg/CE/ha) and Madhya Pradesh (325 Kg/CE/ha). The same observations were found in conservation farming method. Maximum worldly Carbon emission from rice-wheat crop sown by traditional farming was found in Punjab (726 Kg/CE/ha), Haryana (538 Kg/CE/ha), Uttar Pradesh (445 Kg/CE/ha) and Madhya Pradesh (441 Kg/CE/ha). Fixed Carbon emission due to conservation farming was found in Punjab (20%), Haryana (20%), Uttar Pradesh (26%) and Madhya Pradesh (13%), whereas the ratio of yield & investment in carbon emission in conservation farming is found in Madhya Pradesh (2.0), Haryana (1.8), Punjab (1.6) and Uttar Pradesh (1.5).
