A new LED display screen has been installed on the St Pancras library building (Camden Town Hall extension building) on Euston Road.

Messages displayed will show real time data (refreshed hourly) of current levels NO2 (nitrogen dioxide) and PM10 levels, two of the key pollutants in the borough of Camden. The sign is funded by DEFRA and is based on the government’s air quality index.

Euston Road is one of the most polluted roads in London.

NO2 data will be taken from the Euston Road monitoring site, whereas PM10 data will be taken from the monitoring site on Marylebone Road, which is about 1km away from the display sign, until an analyser is installed at Euston Road later this year.
