Carbon FootprintThe total amount of greenhouse gases
produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).
A carbon foot print is the total amount of CO2 and other green house gases emitted over the full life cycle of a process or product. It is expressed as grams of CO2 equivalent per kilowatt hour of generation
Ref.: Postnote October 2006 Number 268 Carbon footprint of electricity generation. www.parliament.uk/post

Equivalent CO2 emission
Fuel type Unit
CO2 emitted per unit
Petrol One gallon (UK) 10.4 kg
Petrol One liter 2.3 kg
Diesel One gallon (UK) 12.2 kg
Diesel One gallon (USA)
9.95 kg
Diesel One liter 2.7 kg

Approach in Experiment for CA practices
Saving conventional source of energy in crop production
Curtailing energy consumption by new/improved management practices
Intensification and diversification with best management.
Estimating energy consumption on the basis of carbon footprint principle.

Estimation of carbon footprint Tillage practice –diesel consumed ~ CO2 emission (3.15 kg per litre)
Ref : G. Trümper et.al. 2010 Carbon dioxide emissions of different soil tillage systems
ASA-CSSA-SSSA International Annual Meetings, Oct. 31-Nov. 3, Long Beach, CA
Irrigation – electricity consumed (kwh) ~ CO2 emission (1000 g per kwh)
