The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al.

Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

A large body of work shows that exposure to road traffic and air pollution may be a trigger of adverse cardiovascular events such as angina, myocardial infarction, and heart failure, with long-term exposure increasing the lifetime risk of death from coronary heart disease.

or fine-particulate matter, is exhaust from vehicles, especially from diesel engines. The California Air Resources Board commissioned the studies to further investigate the connection between fine particulate pollution and public health impacts in California. Particle Pollution (PM 2.5 ) in California Using a. Earlier post.).

New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Mullite is not only easier to produce than platinum, but also better at reducing pollution in diesel engines. Kyeongjae Cho.

While that report projected vessel activity, it did not explore the environmental impacts of increased shipping in terms of air emissions or the potential climate impacts from increases in short-lived climate pollutants such as black carbon.

Study finds that diesel school bus emission retrofits reduce tailpipe emissions, but dont do much for pollution in passenger cabin

Green Car Congress

A UCLA study of the performance of retrofit systems for diesel-powered school buses has found that while the systems significantly lowered tailpipe emissions, there was no unequivocal decrease for in-cabin air pollutants after retrofitting. In-cabin filtration might be a short-to-medium term alternative strategy to protect children’s health.

Air pollution externalities of 12–14 ton HGV on highway (Euronorm III) in euro cents. A new report from the European Environment Agency (EEA) suggests that new road charges for heavy goods vehicles (HGVs or lorries) should reflect the varied health effects of traffic pollution in different European countries.
