More Camden residents are inquiring about air quality following the installation of London’s first real time air pollution sign, according to Camden council.

In June 2012, the council installed the LED sign on the outside wall of its offices on Euston road.

Funded by Defra, the poster-sized sign displays live air quality messages to drivers, cyclists and pedestrians on what is one of the most polluted roads in the capital.

Messages are triggered by hourly measurements of two key pollutants in Camden; nitrogen dioxide and particulate matter. If the concentrations of these pollutants are low according to the Government’s UK Daily Air Quality Index, the sign will display a range of sustainable transport and health messages. When concentrations of pollutants are moderate or high, the messages will change to warn of elevated air pollution and its impact on pedestrians and cyclists.
