From Green Car Reports:
Illegal emissions tampering on diesel trucks is rampant—and apparently a big business
BENGT HALVORSON
NOVEMBER 29, 2020
About 15% of U.S. diesel trucks that were originally certified with emissions controls have had those systems tampered with.
That’s among the takeaways from a U.S. EPA report released last Friday. It suggests an environmental and public-health impact that within the U.S. could exceed that of the Volkswagen diesel scandal, given the prevalence of such trucks.
The report, from the EPA’s Air Enforcement Division (AED), and made available by the New York Times Wednesday, projects that emissions controls have been removed from more than 550,000 diesel pickups in the last decade, adding more than 570,000 tons of nitrogen oxides (NOx) and 5,000 tons of particulate matter over the lifetime of the vehicles.
It gets worse. The report concludes that “due to their severe excess NOx emissions, these trucks have an air quality impact equivalent to adding more than 9 million additional (compliant, non- tampered) diesel pickup trucks to our roads.”
