TITLE:

COMPARATIVE ANALYSIS BETWEEN CO2 EMISSION ESTIMATION METHODS FOR TRUCKS IN THE TRANSPORT OF GRAIN

KEY WORDS:

CO2 emissions, Fuel consumption, Soybean and corn transportation

SUMMARY:

Freight transport is predominantly carried out by road in Brazil and, as one of the largest producers of soybeans and corn in the world, the movement of these grains is of great importance in the country's logistics network. The state of Mato Grosso is the largest producer of these agricultural products and part of its production is destined for export, which requires a movement of average distances greater than 1,000 kilometers. Thus, there is a need to quantify the amount of CO2 emitted in the transport of this cargo from its point of origin to the port to be exported. Therefore, after defining the municipality of Sorriso-MT as the largest producer of corn and soy in the country and the port of Santos-SP as the largest exporter of these grains, a road route was traced and the amount of grain moved was estimated, between these two points. The Brazilian truck fleet was characterized and, adopting the bit-train vehicle, the amount of trips needed to transport the entire estimated load was calculated. The fuel consumption and CO2 emissions of these trucks were then estimated based on the IPCC Bottom-up methodology, which were adopted as a reference. It is then proposed to build consumption equations based on data from heavy vehicles provided by a fleet monitoring company so that it would be possible to calculate, together with speed cycles also obtained from these data, the fuel consumption of vehicles in operation on the desired route. The results obtained from the proposed procedure showed a good degree of agreement with that obtained by the Bottom-up methodology. The VECTO tool was also used to carry out simulations from the data obtained to find a third estimate of gas emissions, however, the results obtained were not consistent with the adopted reference and it was concluded that the program is not adequate to be used in the Brazilian reality without due prior adjustments. Finally, it was concluded that the studied logistics chain emits between 63.52 and 74.09 thousand tons of CO2, which corresponds to up to 47.60 kg of CO2 per transported ton.
