New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

in collaboration with scientists at the University of York’s Stockholm Environment Institute (SEI); University of Colorado; and the International Institute for Applied Systems Analysis, assessed 30 studies of vehicle emissions under real-world driving conditions in 11 major vehicle markets representing 80% of new diesel vehicle sales in 2015.

Study estimates ~4M children worldwide develop asthma each year because of NO2 air pollution

Green Car Congress

The study, based on data from 2010 to 2015, estimates that 64% of these new cases of asthma occur in urban areas. NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health.

In the EU exposure to fine particles and ozone claims 180,000 lives a year, including 35,000 in Germany. According to epidemiological studies, fine particulate matter leads to cerebrovascular, heart and pulmonary diseases and lung cancer, while ozone tends to cause pulmonary conditions such as chronic cough and shortness of breath.

The mid-range estimate assumes that approximately 2% of annual vessel traffic through those canals is diverted through the Bering Strait in 2025, largely through the Northern Sea Route nearest to Russia. MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances.
