• Objective: The objective of this technological article is to present a practical tool for calculating CO2 emissions based on fuel consumption applied in a small road freight transport company.

    Theoretical Framework: There are 4 methods available in the literature for calculating CO2 emissions produced during cargo transport, which stand out for their applicability: (1) GHG Procol; (2) MNT; (3) DEFRA; and (4) GLEC. The authors (Leonardi & Baumgartner, 2004; Lewis et al., 2016) have methodologies for calculating emissions from freight transport, which currently present significant variability in the approaches and databases recommended. The main methodologies in this area are based on two main foundations: (1) fuel-based methodologies; (2) activity-based methodologies.

    Method: The calculation methodology used is based on fuel consumption (bottom-up), which considered the characteristics of the target fleet, the number of vehicles and their technological phase, the actual intensity of fleet use in operation, and real fuel consumption.

    Results and Discussion: From this initial information, it was possible to obtain the volume of CO2 emissions specific to the fleet, considering vehicles using regular diesel and biodiesel (S10). The results indicated a fleet CO2 emission of 1,643 tons per year with the use of biodiesel (S10), representing a 10.5% reduction compared to the total CO2 emission from regular diesel.

    Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results can be applied or influence practices in the field of [insert field of study]. These implications could encompass [list impacted areas or sectors].

    Originality/Value: This technological article contributes to the presentation of a review of CO2 emission calculation models available in the literature and the selection of a methodology for easy application for small and medium-sized road freight transport companies.
