The last gasoline-powered car will have to be sold by about 2035 to put the world on track to limit global warming to the most stringent goal set by world leaders last year, a study said on Thursday.
The report, by a Climate Action Tracker (CAT) backed by three European research groups, said a drastic shift was needed towards clean electric cars and fuel efficiency since transport emits about 14 percent of world greenhouse gas emissions.
Last December, world leaders at a Paris summit set a goal of limiting a rise in temperatures to “well below” 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial times while “pursuing efforts” for a much tougher 1.5 C (2.7F) ceiling.
“We calculate that the last gasoline/diesel car will have to be sold by roughly 2035,” the CAT report said, to make the car fleet consistent with staying below 1.5C. It assumes the last fossil-fuel vehicles would be on the roads until 2050.
The CAT is one of the main groups that monitors government actions to restrict global warming and includes researchers who are authors on U.N. climate reports.
