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.

Technology pathways for diesel engines used in non-road vehicles and equipment
Current non-road regulatory programs lag behind comparable programs for on-road diesel engines, and are not stringent enough to compel the use of the best available technologies for the control of PM and NOx emissions.
White paper
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.

Black carbon: Bringing the heat to the Arctic
On her 32-day voyage through the Northwest Passage, the Crystal Serenity probably emitted a bit more than 1 metric ton of black carbon, a climate forcer about 3200 times more powerful than CO2—and in the Arctic, pretty much the worst place possible.

A world of thoughts on Phase 2
Regulatory action to address CO2 emissions and fuel use from heavy-duty vehicles is accelerating around the world. With that in mind, we've been keeping an eye on how the Phase 2 announcement has been covered in markets outside the U.S.

Heavy fuel oil is considered the most significant threat to the Arctic. So why isn’t it banned yet?
When we know that heavy fuel oil is the biggest threat to the Arctic marine environment, dangerous to human and environmental health, and already banned in the Antarctic, shouldn’t we seriously consider prohibiting its use in the Arctic?
