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.

More popcorn = More super-credits
The new edition of the EU Vehicle Market Statistics pocketbook is filled with detailed statistics for 2001–2013. For the first time we also include some data on heavy-duty vehicles, and of course some international comparisons as well.

A reality check on biomass ambitions
Generating energy from some types of biomass can deliver high GHG emission reductions, but could there be enough of these resources to go around if the entire world looked to deliver 20% of its energy needs from biomass?

Considering Co-benefits: Counting the role of non-CO2 climate pollutants in the near and long term
To put the climate co-benefits of vehicle emissions standards in perspective: In the near-term, currently enacted emissions add 50% to the CO2-e reductions from on-road vehicles in 2030, a climate impact that could be doubled by extending stringent emission standards throughout the rest of the world.
