programs / Heavy-duty vehicles

Translate

The steady growth in freight transport by truck presents a challenge to efforts at reducing hazardous air pollution and greenhouse gas emissions. Though most countries have fuel economy standards for passenger vehicles, as of 2011 only Japan and the United States have set efficiency and GHG emission standards for heavy-duty vehicles.

Most heavy-duty vehicles are powered by diesel engines that, without pollution controls, can emit high levels of other pollutants that contribute to global warming  and local air pollution.  For example, uncontrolled diesel vehicles produce high levels of particulate matter, a fraction of which has a warming effect, and nitrogen oxides, which are an ingredient of ozone (also known as smog), an important greenhouse gas. These pollutants are associated with bronchitis, asthma, and other lung diseases, and are responsible for millions of premature deaths worldwide. In 2013, the World Health Organization classified diesel exhaust as carcinogenic to humans, based on evidence of an increase in lung cancer after long-term exposure.

Cities driving diesel out of the European car market
European governments have strong incentives to discourage diesel technology and national governments could face fines for failing to meet ambient air quality standards for NOx. As a result, several cities are moving fast to phase out diesel cars, which account for 80% of all NOx emissions from vehicles in Europe.

Shell game? Debating real-world fuel consumption trends for heavy-duty vehicles in Europe
The EU is about to propose new standards to limit CO2 emissions from heavy-duty vehicles. Some manufacturers are still trying to persuade policy makers that regs aren't necessary because truck fuel-efficiency really is improving significantly on its own. Don't be fooled; on average, it isn't.
