Beyond a One-Time Scandal: Europe’s Ongoing Diesel Pollution Problem (4 page pdf, Charles W. Schmidt, Environ Health Perspect, Jan. 2, 2016)
Today we review a recent assessment of the role of diesel vehicles in causing PM2.5 and NO2 and greater mortality as a result while also being the technology of choice, particularly in Europe with over 50% of vehicles with it, to reduce C02 emissions and mitigate climate change. The comparison with the US and Canada is striking where less than 3% of vehicles are diesel and CO2 emissions have soared from gasoline powered vehicles and less attention to emission reduction than in the EU. Clearly an optimum choice or balance needs to be made that looks at both the immediate health impacts of diesel and the equally important need to reduce carbon emissions.
