The Coronavirus, Immissions
and the Combustion Engine

The coronavirus pandemic is providing unique experimental data not only for researchers but also for politicians with responsibility for the environment and transport. The lockdown measures resulted in a sudden and dramatic fall in the volume of personal and freight transport and a halving of the traffic peaks. We could have been justified in thinking that levels of air pollution in the form of carbon dioxide, nitrogen oxides and particulate matter should also have fallen. But there is no clear evidence that this is the case for nitrogen oxides and particulates.
