Chalmers study: ban on sales of fossil-fuel cars greatly reduces lifecycle GHG mainly due to tailpipe emissions; risk of carbon leakage in manufacturing
2 emissions, according to a new lifecycle study by researchers at Chalmers University of Technology, Sweden.
However, the full effect of a ban is delayed due to fleet inertia. Further, risks of carbon leakage over the full vehicle lifecycle may need to be addressed by extending current regulations of vehicle-specific tailpipe emissions to also cover carbon footprints for new cars, the researchers said.

The researchers considered emissions from the entire lifecycle from the manufacture of electric cars and batteries, to electricity used for operation. The total effect of a phasing out of fossil-fueled cars will not be felt until the middle of the century and how the batteries are manufactured will affect the extent of the benefit.

If a ban were introduced on the sale of new petrol and diesel cars, and they were replaced by electric cars, the result would be a great reduction in carbon dioxide emissions. That is the finding of new research from Chalmers University of Technology, Sweden, looking at emissions from the entire life cycle – from manufacture of electric cars and batteries, to electricity used for operation. However, the total effect of a phasing out of fossil-fuelled cars will not be felt until the middle of the century – and how the batteries are manufactured will affect the extent of the benefit.
