Air pollution in Edinburgh improving with more people cycling
The reduction is significant along the A8 which, due to traffic congestion, has long been a pollution hot spot.
Edinburgh Council claims the city's air quality is improving and it is, in part, due to more people taking the bike to work.
A progress report for the local authority's Transport and Environment Committee contains data collected in 2015.
Early figures for 2016 suggest the downward trend is continuing.
The reduction is significant along the A8 through Corstorphine which, due to traffic congestion, has long been a pollution hot spot.
The number of people cycling to and from work has increased from about 5% in 2011 to 7% in 2015.
But there is still concern in other parts of the city, including Salamander Street in Leith - where pollution is thought to be linked to industry in the area.
Transport Convener Councillor Lesley Hinds welcomed the improvement and said, "Although these figures are a welcome and very encouraging sign that our efforts to combat air pollution in Edinburgh are paying off, we cannot and must not be complacent.
"Air pollution remains one of the main threats to ‘quality of life’ in Edinburgh and this Council continues to work extremely hard to address pockets of poor air quality in the city.
"Measures to make walking, cycling and public transport as attractive as possible will greatly benefit the Capital's air quality and quality of life".
