For decades, concerns about automobile pollution have focused on what comes out of the tailpipe. Now, researchers and regulators say, we need to pay more attention to toxic emissions from tires as vehicles roll down the road.
Tires emit huge volumes of particles and chemicals as they roll along the highway, and researchers are only beginning to understand the threat. One byproduct of tire use, 6PPD-q, is in regulators' crosshairs after it was found to be killing fish.
Automobile dealers want the Biden administration to quit trying to force them to vroom vroom down electric avenue.
Last year, fewer than 8 percent of new cars sold in the United States were EVs. The goal of the tailpipe emissions rule is to get that to nearly 60 percent — not including hybrids — in just eight years.
As the United States aims to accelerate its shift to electric vehicles (EVs), social media users cite a report on tire emissions to claim such cars pollute significantly more than their gas-powered peers. But the posts misrepresent the analysis by omitting the effect of carbon dioxide (CO2) emitted from tailpipes -- and while the environmental impact of EVs depends on how they are manufactured and charged, industry experts say they are more sustainable overall .
