The research conducted by the German VDI Institute of Automotive Engineers reveals surprising ratings for plug-in vehicles in their ability to reduce air pollution, which is similar to that of electric cars and much better than gasoline and diesel vehicles. The advantage of hybrid vehicles is that they begin reducing air pollution almost immediately upon hitting the road, unlike electric cars which carry a “penalty” due to the emissions produced during the battery production process. The study focused on the greenhouse gas emissions of various types of vehicles over their average lifespan of 200,000 km, based on data from a compact family car with the same propulsion system.
Dr. Joachim Demski, the institute’s president, highlights the importance of considering factors such as production site, energy mix, and propulsion system when assessing emissions over a vehicle’s lifecycle. He notes that electric and hybrid vehicles start with an ecological burden due to the resource-intensive production process, particularly in battery production which primarily occurs in Asia. Despite this, electric cars are able to balance their emissions after around 90,000 kilometers of driving, emitting 24.2 tons of CO2 compared to 24.8 tons emitted by hybrid cars after 200,000 kilometers. Diesel cars emit 33 tons and gasoline cars emit 37 tons over the same distance.
Plug-in vehicles, which use gasoline and a less polluting battery, offer a more environmentally friendly option compared to traditional gasoline or diesel vehicles. While hybrid cars do emit pollution from their exhaust due to gasoline usage, they have a smaller battery than electric cars, resulting in lower emissions during production. Regular hybrid cars, even without charging from an outlet, can achieve similar emission data as plug-in cars. The researchers stress the importance of considering various variables that can influence emissions, such as power sources for electric cars and the charging habits of hybrid owners.
Dr. Demski highlights the need for more sustainable practices in battery production, including manufacturing batteries in Germany using green energy, improving battery recycling processes, and expanding renewable energy sources for electricity production. The research underscores the importance of evaluating the complete lifecycle of vehicles, considering greenhouse gas emissions from production, use, and disposal. By addressing these key factors and transitioning towards cleaner energy sources, the automotive industry can work towards reducing air pollution and promoting more sustainable transportation options.
