on •Public Release: 15-May-2017University of YorkA study, published in Nature, has shown that laboratory tests of nitrogen oxide emissions from diesel vehicles significantly underestimate the real-world emissions by as much as 50 percent. Chris Malley, from the SEI, University of York, said: “This study shows that excess diesel nitrogen oxide emissions effect crop yields and a variety of human health issues. “For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions.”The study estimates that excess diesel vehicle NOx emissions in 2015 were also linked to approximately 38,000 premature deaths worldwide – mostly in the European Union, China, and India. Susan Anenberg, co-Founder of Environmental Health Analytics, LLC, said: “The consequences of excess diesel NOx emissions for public health are striking. In Europe, the ozone mortality burden each year would be 10% lower if diesel vehicle nitrogen oxide emissions were in line with certification limits.”At a global level, the study estimates that the impact of all real-world diesel nitrogen oxide emissions will grow to 183,600 early deaths in 2040, unless something is done to reduce it.
