A study by Volvo found that electric cars can emit 70% more carbon than ordinary combustion-powered cars. To reach the number, the Swedish automaker compared the electric C40 and the traditional XC40 models in a charging scenario with conventional forms of energy and another with clean sources.
Volvo intends to market only electric cars until 2030 and decided to understand the path it should take to achieve the measure in the next 9 years. For the methodology used in the research, the assembler took into account the entire life cycle of a car, from raw material mining, transport, amount of carbon emitted, disposal of waste produced and the life cycle of a vehicle after 200 thousand kilometers traveled.

According to the survey, when a C40 is recharged with clean energy sources, the lifecycle carbon footprint is approximately 27 tonnes of CO², while an XC40 moves 59 tonnes of CO².
In scenarios where the C40 is recharged with the average global energy matrix (about 60% fossil fuels) the carbon footprint increases to up to 50 tons and practically wipes out all the environmental benefits of an electric car.
Electric cars offsetting carbon
In Germany, for example, around 27% of electricity is produced from wind, while in the United Kingdom, 42% of production is obtained by burning natural gas. Thinking about these differences in the European reality, Volvo set up a “universal” scenario for the study, with half of the energy generated in a renewable way – wind, solar, geothermal – and the other in a conventional way – hydroelectric, coal and nuclear.
Electric cars “zero” emissions from the 109,000 km driven. After surpassing this mark, they offset the emissions of the entire production process and the electric one is no longer 70% more polluting and 15% more sustainable than conventional models.
The automaker also pointed out that if a vehicle is fueled only with clean energy, the car’s sustainability reaches 30%. In this scenario, the tram already offsets the emission of toxic gases with only 48 thousand km traveled.
“We need governments and energy companies around the world to increase their investments in clean energy capacity and related charging infrastructure so that all-electric cars can deliver on their promise of cleaner mobility,” Chief Executive Håkan Samuelsson said in a statement. from Volvo.
He said the company maintains its goal of becoming an all-electric car manufacturer, but this transition needs to be made with the support of other agents to generate considerable impacts on the environment.
