China study connects ozone pollution to cardiovascular health

Green Car Congress

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The findings associated ozone exposure with markers of platelet activation and increased blood pressure.

London and Paris launch car scoring initiative based on real-world emissions; ICCT the technical lead

Green Car Congress

This new undertaking will capture detailed information on pollutants from vehicle exhaust using remote-sensing equipment and portable emissions monitoring systems. Paris and London have committed to launch their data online by the end of 2017.

Study finds air quality models significantly underestimate traffic as source of NOx in Europe

Green Car Congress

Exhaust from modern gasoline powered engines, despite higher ignition temperatures than those powered by diesel, can be effectively treated for NO along with NMVOC (and CO) using a three way catalytic (TWC) converter. 85% is modelled to be emitted by the passenger car fleet based on the COPERT model and TRACCS database. —Karl et al.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

We estimate ozone and SOA formation potential. Therefore, the secondary organic aerosol and ozone formation potential of the exhaust does not depend on engine technology. Measurements include gas- and particle-phase emissions, particle number, particle size distributions, and speciated NMOG emissions. —Saliba et al.
