According to the OECD, wear and tear on brakes and tires could soon represent the primary source of road traffic pollution, ahead of exhaust gases.
The wear of brakes, tires and road surfaces could soon represent the first source of atmospheric emissions of particles linked to road traffic, in front of the exhaust fumes, alerted the Organization for Economic Cooperation and Development (OECD) in a report published Monday, December 7, 2020.
Fewer exhaust emissions with the proliferation of electric vehicles
As the quantity of particles released via exhaust gases is expected to decrease with the proliferation of electric vehicles, “the majority of particulate emissions attributable to road traffic could come from sources other than exhaust from 2035”, explains the OECD.
According to Walid Oueslati, an economist at the OECD and coordinator of the report, this pollution will play “a central role in the future”. “At the national level, public policies must take this pollution into account. And we also need international cooperation on this subject,” he said.
The OECD report first stresses the need to establish standardized methods for measuring non-tailpipe emissions.
He also suggests that electric vehicles should not be exempt from tolls intended to reduce automobile pollution. Rather, regulations targeting road traffic should take into account the tailpipe and “non-tailpipe” emissions of all vehicles, and take into account factors such as vehicle weight and tire composition, the report’s authors stress.
Finally, policymakers should also prioritize measures that shorten motorized travel, limit vehicle access to urban areas and encourage public transport, walking and cycling, the report concludes.
