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.

Italy’s car market needs to make a U-turn
Between minuscule electric vehicle (EV) sales, growing diesel shares, and Italian carmakers’ struggle to curb carbon dioxide (CO2) and nitrogen oxide (NOx) emissions, there is no doubt that Italy is heading in the wrong direction, but it’s not too late for a U-turn.

Will the future RDE regulation be enough to restore trust in diesel technology?
The success of the RDE regulation will depend on the will of manufacturers to prove that they have learned a lesson from Dieselgate by beginning to focus on reducing real-world emissions, not just on passing a particular test.
