Shifting UK Car Exhausts to the Right Could Dramatically Cut Roadside Air Pollution

Shifting UK car exhausts to the right could dramatically cut roadside air pollution

Harmful air pollutants on U.K. pavements generated by diesel cars could be slashed by a third if car exhausts were positioned on the right, according to a new study published in ACS ES&T Air.

Offside exhausts would reduce contribution to roadside pollutants by a third

New research from the University of York has managed to quantify the benefits to roadside air quality in the UK if all diesel cars had their exhausts positioned on the offside (right) of the vehicle. While it might seem intuitive that this would be the case, it has hitherto been a very difficult thing to measure.  The availability of high-speed (fast-response) pollution sensors, which take measurements several times per second, has allowed the r…
