The mitigation potential is being estimated for each intervention:
1. Eco-driving courses: Between 2 and 3.5MtCO2e/year.
2. Technological improvement: Between 0.3 and 1MtCO2e/year
3. Modernization of the fleet: average of 2 MtCO2e/year.
Total mitigation cannot be calculated through the accumulated sum of the three interventions.
Due to the fact that the sector is highly dynamic, the calculation of the baseline CO2 emissions were calculated via a bottom-up approach since it gives a higher certainty.
The input data used for this methodology are:
- Vehicle fleet
- Intensity of use
- Eficiencia Bruta
- Fuel information
These parameters, defined in the next section, are being used to calculate the following variables:
- Mileage per vehicle type
- Net emissions
- Total emissions
- Fuel consumption
The following section describes the calculation of these variables in broad terms:
1. The vehicle fleet (number of vehicles), is being multiplied by the intensity of use (km/year) to obtain mileage per vehicle type (km/year). Vehicles are then being classified into four different types: C2, C3, T2 and T3. This variable allows calculating fuel consumption and total emissions.
2. By multiplying gross efficiency (km/lt) with a loss factor “on road”, one calculates net efficiency (km/lt). Dividing mileage by net efficiency, we obtain total fuel consumption per year (lts/year). 3. Finally, dividing the emission factor (kgCO2/lt) by the net efficiency, one obtains net emissions of the vehicles (kgCO2/km). The product resulting of the multiplication of the latter by mileage equals total emissions per year (MtCO2/year).
