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.

Designing from scratch: Maximizing aircraft fuel efficiency
Why aren’t we seeing more radically fuel-efficient aircraft, the way we're seeing more efficient cars and trucks? You can get a lot of different answers to that question, depending on who you ask. The result is a series of interviews, which we'll be publishing here over the next few weeks.

Vehicle and fuel standards can dramatically reduce air pollution in Brazil, São Paulo’s air quality data demonstrate
Implementing P-8 (Euro VI-equivalent) standards for trucks and buses might be the most cost-effective way to improve air quality, not just in São Paulo but nationwide. The benefits associated with P-8 standards outweigh their costs by a ratio of 11 to 1.

Subsidy fraud leads to reforms for China’s EV market
Policy adjustments, created largely in response to the high-profile subsidy fraud scandal, mark major reforms for China’s EV market. As an old Chinese saying goes, “A loss may turn out to be a gain.” After being struck by this scandal, China’s EV market may find the right path toward a prosperous future.
