Public Health Impact and Economic Costs of Volkswagen’s Lack of Compliance with the United States’ Emission Standards

Public Health Impact and Economic Costs of Volkswagen’s Lack of Compliance with the United States’ Emission Standards | Atmospheric Chemistry | Scoop.it
The U.S. Environmental Protection Agency (EPA) recently issued a notice of violation against Volkswagen (VW) for installing a defective device in certain models of diesel cars to circumvent emission tests for nitrogen oxides (NOx). We quantified the health and economic impacts of extra NOx emissions attributable to non-compliant vehicles in the U.S. using the EPA’s Co-Benefits Risk Assessment model. We estimated that the total extra NOx emitted over one year of operation would result in 5 to 50 premature deaths, 687 to 17,526 work days with restricted activity, and economic costs of $43,479,189 to $423,268,502, based on various assumptions regarding emission scenarios and risks. This study highlights the potential impacts of VW vehicles’ lack of compliance on the health and well-being of the U.S. population.
