York study: Less traffic in first UK lockdown reduced NO2 pollution but caused increase in surface ozone

Green Car Congress

Less traffic on the roads during the first COVID-19 lockdown in the UK led to a reduction in air pollution but may have caused potentially damaging surface ozone levels to rise, according to a new study led by researchers at the University of York. The 25–75% range is shown by the shaded area. These results are a cautionary tale.

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

This study will measure concentrations of non-tailpipe (NTP) particulate matter across Toronto, Canada to determine how much non-tailpipe pollution people might breathe in everyday life and how to better measure these exposures in the future. and PM 10 , including of NTP and TP emissions, at key selected London trial sites.

HEI study finds London Congestion Charging Scheme shows little evidence of improving air quality

Green Car Congress

The London Congestion Charging Scheme (CCS)—which charged for travel into central London and reduced traffic volume ( earlier post )—has shown little evidence that it improved air quality as well, according to Part I of a new study published by the Health Effects Institute (HEI). Resources.

COVID-19 Forced Us All to Experiment. What Have We Learned?

Cars That Think

And it's already clear that the COVID-19 pandemic has sped up the arrival of the future along several dimensions. To find the upside of emergencies, we first looked at the economic effects of a tidy little crisis, a two-day strike that partially disrupted service of the London Underground in 2014.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. At the same time, LCA models need to be improved and further developed to treat future technologies with a minimized level of uncertainty. Simpson et al.
