U Birmingham study finds DPFs have limited impact on ultrafine particle emissions

Green Car Congress

A study by researchers at the University of Birmingham in the UK has found that while Diesel Oxidation Catalysts (DOCs) and Diesel Particle Filters (DPFs) has been very effective in controlling the tailpipe emissions of solid particles, there has been little change in the liquid mode ( 104 cm −3 /24-hour mean) defined by WHO.

Study: tightening vehicle emissions standards resulted in higher rates of automaker non-compliance; unintended effects of threshold-based regulations

Green Car Congress

A new study focused on the auto industry finds that tightening emissions standards not only fails to curtail on-road emissions, but actually increases the likelihood of non-compliance by automakers. Economically, automakers have little financial incentive to abide by the tight emissions standards. —Hu et al.

Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

A new study led by researchers from Northwestern University projects that if electric vehicles replaced 25% of combustion engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. The open-access paper is published in AGU’s journal GeoHealth.
