Cambridge has a problem with its air quality. At the beginning of this year, the EU Directive on Air Quality became legally binding in the UK. In parts of the city centre, particularly around Drummer Street bus station, the atmospheric pollution at times breaches the average annual legal level designated by the EU.
We have cautiously supported the recent Transport Commission’s report, which highlighted the need for Congestion Charging in Cambridge in tandem with major quality improvements to sustainable transport such as travel by bus and bike. Currently Cambridgeshire County Council is consulting the public on its Local Transport Plan* that will be effective from 2011 and covers the city and the rest of the county.
Recent discussions with local people have highlighted the particular but not exclusive inner city problem of poor air quality within some public areas. We consider this an important issue, which needs to be tackled. We are very keen to hear your views on the air quality problems facing the city and how you think that the issues could best be managed.
We are also keen that air quality is identified within the Local Transport Plan as a priority.
The average annual level of Nitrogen Dioxide, one of the main markers of atmospheric pollutants in cities, permitted by the EU is 40 micrograms/metre3 of air. In the quieter residential streets, it is about 29-33 mcg/m3 – below the threshold as set by the EU. However at the main ring road intersections, it is about 42-45mcg/m3, and around the bus station and stops at Drummer/Emmanuel Street, the level averages around 55mg/m3 and may exceed 100mg/m3 at times of peak traffic and stable weather conditions. Although rarely breaching the maximum EU ceiling of 200mg/m3, air pollution is worsening. In the last three years 20% more buses are operating within the city but the Nitrogen Dioxide emissions of buses have only been reduced by 12.5%.
Atmospheric pollution from vehicles, including Nitrogen Dioxide, has been linked to increases in asthma and respiratory problems, and even to premature deaths in the UK. Because of its acidity, it also accelerates the corrosion of the stonework on historic buildings.
In Cambridge one of the primary sources of this pollution is the exhaust fumes from buses. Around Drummer Street, buses account for approximately half the pollution load. Halving these emissions by introducing cleaner vehicles would bring the pollution levels below the EU standard.
Buses are a key part of our efforts to reduce congestion. CambridgePPF is not anti-bus – in fact we need more buses to get people out of their cars, but we also need buses that are cleaner and less polluting. Anyone visiting the city centre will recognise the problem of some buses spewing out clouds of diesel exhaust in the faces of pedestrians and cyclists, and what a relief it would be to have clean buses.
Cleaner buses obviously come at a cost, and this in turn could impact on services or fares. There is an inevitable trade-off between reduced emissions and maintaining services. We need to work with the operators to explore how best to introduce the higher pollution standards without impacting on fares. However, because of the legal requirement, it is not a matter of whether we should clean up our air but of how best to do it.
As Cambridge continues to expand, the number of buses will increase. The issue therefore is how to reduce emissions without threatening services and fares.
In essence, this presents a choice – should priority be given to cleaning Cambridge’s air and alleviating the potential public health problems or to maintaining services and fares at all costs?
This is the debate CambridgePPF wants to stimulate. We will be seeking to raise the issue with the City Council, that has responsibility for the city’s air quality, the County Council, that is responsible for the buses, the bus operators and the public.
Your views on this issue will help us to campaign for better quality air within the City.
