What are Emission Standards and What is the Purpose of Emissions Testing?

Emission standards are the legal requirements governing air pollutants that are released into the atmosphere. The United States Environmental Protection Agency (EPA) regulates emissions from a wide range of vehicles, engines and equipment. Beginning in the mid-1970s, the EPA established emission standards for specific pollutants, including carbon monoxide, hydrocarbons, nitrogen oxide and particulate matter.

In addition to emission standards set by the EPA, the California Air Resources Board (CARB) may also adopt and enforce its own standards regarding vehicle emissions. Vehicles sold in European Union member states are required to meet certain acceptable limits for exhaust emissions of new vehicles sold.

Emissions tests check and monitor the levels of hazardous materials and pollutants that may escape from a vehicle. Emissions tests can potentially help lower the amount of pollutants released into the air and help the air quality of the environment.

Effects of Vehicle Emissions

According to the EPA, air pollution emitted from vehicle emissions contribute to smog (a mixture of pollutants made up mostly of ground-level ozone) and poor air quality, which can potentially have a negative impact on the health and welfare of U.S. citizens.

Pollutants that contribute to poor air quality include:

  • Particulate matter, or a complex mixture of extremely small particles and liquid droplets that get into the air that can potentially affect the heart and lungs
  • Volatile organic compounds
  • Nitrogen oxides (NOx), a group of highly reactive gases that enter the air from the burning of fuel

Breathing in air with high concentrations of nitrogen oxides, particularly nitrogen dioxide (NO2), can potentially irritate airways in the human respiratory system. Short-term exposure can aggravate respiratory diseases (such as asthma) and lead to respiratory symptoms, emergency room visits, and hospitalizations. Long-term exposure can contribute to the development of asthma and possible lead to an increased risk in respiratory infections.

Nitrogen dioxide and other nitrogen oxides can potentially lead to harmful effects on the environment as well, including acid rain, haze and nutrient pollution.

Heavy-Duty Emissions Standards


In order to reduce serious health and environmental effects caused by vehicle emissions, the EPA has enacted a variety of standards for light-duty passenger vehicles, motorcycles, and heavy-duty commercial trucks and buses. Most of the regulations related to commercial trucks and buses deal with diesel engine vehicles, including certain heavy-duty pickup trucks.

Has There Been a General Motors Emissions Class Action Lawsuit?

According to multiple reports, General Motors faces a proposed class action lawsuit for allegedly programming approximately 705,000 heavy-duty pickup trucks with Duramax engines to cheat emissions tests and meet emissions requirements. Plaintiffs in the lawsuit claim that certain pickup trucks produce and emit levels of nitrogen oxide anywhere from two to five times higher than allowed.

Vehicles potentially affected include:

  • 2011–2016 Chevrolet Silverado 2500HD with Duramax Diesel Engines
  • 2011–2016 GMC Sierra 2500HD with Duramax Diesel Engines

Vehicle manufacturers are required to demonstrate that their vehicles meet federal emissions standards and to disclose any software or programming that could potentially modify the air pollution a vehicle emits.

According to a report by The New York Times, the lawsuit argues that GM “deceived customers by marketing the vehicles as ‘clean’ diesel trucks and seeks to force the company to buy the vehicles back and compensate owners for economic losses.”

Has There Been a General Motors Recall?

Although a recall has not been initiated for allegedly affected Chevrolet Silverados and GMC Sierras, a proposed class action lawsuit claims that the automakers deceived customers and that those customers suffered damages as a result. Failure to warn consumers can be a basis of product liability, regardless of whether the product has been recalled.

Have There Been General Motors Emissions Settlements?

Some cases settle early in the claims process, but it is not expected that there will be early General Motors emissions settlements. However, other emissions lawsuits have ended in agreements totaling billions of dollars. According to the LA Times, Volkswagen settled with over 88,000 car owners for $1.2 billion, ending most of the litigation VW faced after it was found to have rigged vehicles equipped with 3-liter diesel engines.

Although the cases against Volkswagen reached a settlement, the outcome of any case is never guaranteed and past results are not necessarily predictive of future outcomes.
