While car owners and dealers in some countries--including the United States--were given the opportunity to be a part of a class action lawsuit against Volkswagen, many customers shared that they felt stuck with vehicles they would never have purchased, had they known how detrimental to the environment these automobiles really are. The company faced hefty litigation costs in addition to losses due to a hit in VW's share prices. Shareholders might receive compensation for the drop in share prices if related lawsuits come out in favor of the plaintiffs.
With their nefarious actions, Volkswagen did not only betray its own customers, but the company also violated fuel economy standards set by environmental agencies in various countries: In the United States, selling cars equipped with defeat devices is a violation of the Clean Air Act’s guidelines for emission standards. The U.S. National Highway Traffic and Safety Administration’s (NHTSA) carbon dioxide emissions compliance targets are at 223 grams per mile for model year (MY) 2025 vehicles. To meet these standards by 2025, VW would have to increase average mileage per gallon to about 54.5 mpg, and the most effective means of boosting mileage per gallon is the reduction of weight and horsepower. Typical weight reductions are primarily accomplished by swapping metals for some of the least environmentally friendly materials on earth: plastics and composite materials.
Another aspect covered by the U.S. Clean Air Act is the production of nitric oxide and nitrogen dioxide, collectively referred to as NOx. These greenhouse gases are believed to be particularly hazardous and are major contributors to heavy smog. The EPA issued a notice of violation to Volkswagen in 2015 because the agency believes that real-time NOx emissions of certain Audi and Volkswagen vehicles are up to 40 times higher than they should be, and, though diesel vehicles tend to score better in terms of carbon dioxide emissions, it is these NOx emissions from diesels that remain a cause of concern among environmental activists.
