Stellantis made a comparison to measure CO2 emissions in four different situations, in two different regions, with Europe and Brazil being analyzed.
She used a vehicle fueled with ethanol, compared in real time with the same driving situation in three alternatives: with gasoline type C (E27); 100% electric (BEV), supplied by the Brazilian energy matrix, and 100% electric (BEV) supplied by the European energy matrix.
The test was carried out using methodology and connectivity technology developed by Bosch, considering not only the CO₂ emission associated with the propulsion, but the emissions corresponding to the entire generation cycle in each region and the consumption of the energy used, known as the ‘cycle’ from the well to the wheel’ or ‘from the field to the wheel’, in the case of biofuels.
The test vehicle traveled 240.49 km, obtaining the following CO₂ emissions results during the journey:
- Fuel (E27): 60,64 kg CO2eq
- 100% electric (BEV) with European energy: 30.41 kg CO2eq
- Etanol (E100): 25,79 kg CO2eq
- 100% electric (BEV) with Brazilian energy: 21.45 kg CO2eq
Antonio Filosa, president of Stellantis for South America, analyzed: “The results prove the comparative advantages of the Brazilian energy matrix, mainly the importance of biofuels for a more sustainable mobility”.
According to the Stellantis analysis, “when considering the total balance of emissions from the entire energy cycle, the vehicle powered by ethanol has advantages even in comparison with a battery electric vehicle fueled by energy generated in Europe, considering the characteristics of the matrix European Energy”.
The company continues: “when compared to gasoline, ethanol stands out even more. The final balance shows that, when comparing the two fuels, the use of ethanol avoided the emission of 34.85 kg of CO2eq on the route, equivalent to 144 grams of CO2eq per kilometer driven. Ethanol reduces the carbon footprint by more than 60%.
However, in the same comparison, the electric car with Brazilian energy, obtained in 85% of hydroelectric plants, has the lowest carbon footprint, even surpassing ethanol.
So, what can be seen is that, for manufacturers, the cheapest way to reduce emissions is ethanol, but electric, running here, becomes the most efficient, however, it is still an expensive solution for production in the country. and investment in infrastructure, which does not happen with ethanol, thus giving the fuel an advantage.
