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.

U.S. efficiency and greenhouse gas emission regulations for model year 2018-2027 heavy-duty vehicles, engines, and trailers
Summarizes the final rulemaking on new Phase 2 standards to reduce HDV fuel consumption and GHG emissions. Together with Phase 1, the increased efficiency of HD trucks and buses will cut fuel use by over one-third by 2050.
Policy update
Stage 3 China fuel consumption standard for commercial heavy-duty vehicles
The goal of this new stage of standard is to reduce fuel consumption by about 15% in 2020 from the 2015 levels, in order to further reduce the gap between China and other more developed markets globally.

Is Indonesia finally going in the right direction on palm oil?
If the government is really concerned about reducing GHG emissions by increasing use of biofuels, there is still time to make sure it includes sustainability clauses, for the environment and the smallholders, and doesn’t just cater to palm oil investors.
