Thermal car: here’s why it is better not to get rid of it

Unless you’ve lived in a cave for the last few years, obsession with energy transition you will probably not have escaped your notice. Electric, hybrid or hydrogen cars: all solutions would be good to reduce CO emissions at all costs2 of the transport sector, which should be remembered, only accounts for about a third of global CO emissions2. But according to the public authorities, it would be essential to quickly ban thermal cars and replace them with new electric cars, when they are in perfect working order… What if we were simply on the wrong track?

Japanese researchers at the Imperial University of Kyushu have looked into the question, and are sounding the alarm bells. false good idea : indeed, according to them, keeping your old gasoline car longer would be beneficial for the environment, much more than a forced transition to a new electric car. These scientists therefore validate, with supporting figures, a common sense idea: a vehicle’s carbon footprint is not limited to its exhaust emissions alone, and scrapping cars that are still in good condition. operation is not a good idea.

Energy transition: a counter-productive measure

According to this study, which looked at cars put into circulation in Japan between 1990 and 2016, if current cars stayed 10% longer in service before being scrapped, their CO footprint2 would be reduced by 30.7 million tonnes

, because even if they continue to produce emissions while driving, they will always remain less polluting than the mass production of new cars.

“This means that we can reduce our CO emissions2 just by keeping and driving our cars longer ”, concludes Shigemi Kagawa, Professor at Kyushu University, who specifies that “If the car is relatively new and has good fuel efficiency, the effect is even greater. The next time you think about buying a new car, try to think about whether your current car might not be able to run for a while. “

Japanese researchers are also pointing the finger at government incentives to scrapping working gasoline cars: in addition to being a drain on the state budget, measures like the conversion bonus would be everything. simply counterproductive, by causing an increase of over 42 million tonnes of the carbon footprint of the automotive sector. Thus, destroying an existing vehicle to manufacture a new one would run counter to any ecological approach, however laudable it may be.
