Abstract: For quickly and remotely obtaining the GHG emissions, without providing the sites of raw material production with means for collecting parameters. The system comprises a processing unit to execute instructions related to the determination of the emissions; the database for storing the relevant parameters related to the processes for the production of raw material; a data transmission means connected to the database and the processing unit, to retrieve said parameters from the database and transmitting said parameters to the processing unit, and a GHG emissions modeling module connected to the processing unit and adapted to generate a GHG emissions level. The method comprises considering a partial calculation for the emissions related to any process and adding them up to obtain an overall value for said GHG emissions.
