GHGs (CO2 and CH4 and N2O) emissions from agronomic practices of rubber and sugarcane cultivation and
processing into raw rubber and refined sugar were assessed and then used with data on carbon sequestration, for
rubber4 and for sugarcane10 for the calculation of carbon footprint. Under the agronomic practices of rubber and
sugarcane cultivation, land preparation, transportation of planting materials, transportation and application of
fertilizers were considered. Transportation of field latex to the factory, machinery usage in rubber processing and
drying were the key activities occupied in raw rubber processing, i.e. crepe rubber (CR) and Ribbed Smoked Sheets
(RSS). Similarly, transportation of cane yield to the factory, machinery usage for milling, boiling and drying were
the main steps practiced in processing of refined sugar. Emission of GHGs due to fuel combustion involved in above
activities was taken into account. In addition, process related emissions at refinery stage of fuel were taken into
account. Emission through the electricity usage in factories was counted on the basis of emission values available
for electricity generation. The application of nitrogen fertilizer for both crops was quantified and emissions due to
