Islington Council in London has introduced a fine for motorists who leave their diesel engines running while stationary.

Stationary vehicles that are found to be running on diesel fuel will be charged a £20 on the spot fine as a part of a new measure aimed at curbing pollution in London. The fine will target diesel engines because they are considered to produce pollution that is more harmful to humans.

Counsellor Claudia Webbe, Islington Council’s executive member for environment, said: “We are committed to improving air quality in Islington which is why we are clamping down on idling buses, lorries and diesel cars, as part of our air quality strategy."

The measure is thought to be the first of its kind in the UK, with the possibility of other councils following in its footsteps.

The introduction of the new diesel charge follows Mayor Boris Johnson’s proposed plans to charge drivers of diesel vehicles an additional £10 to enter London’s congestion zone.

Islington council advises drivers to switch off idling vehicles at traffic lights, school drop off zones, and while loading and unloading their vehicles.
