Air quality: A follow up report - Environmental Audit Committee Contents


Written evidence submitted by Air Quality Management Resource Centre, University of the West of England, Bristol

This letter constitutes a response to the Environmental Audit Committee's latest call for evidence on air quality. The points made in our submission to the last call for evidence in December 2009 still stand and this submission should be seen as additional to those. The key points made in our response can be summarised as follows:

—  There is an important relationship that needs to be maintained between action to improve air quality at a national level and at a local level. For a number of reasons this relationship has not been sufficient so far to achieve the UK air quality objectives and limit values, however we feel that that there is a real danger that the government's current intentions with respect to the agendas of "localism" and "deregulation" pose a significant threat to the likelihood of achieving the air quality targets.

—  There is currently a great focus on the failure of EU vehicle emission standards to have achieved good air quality for all. Whilst important, this discussion distracts from the underlying cause of poor air quality which lies with the unrelenting growth in traffic levels. Whilst it is important that vehicles are as clean as possible, there has been too great a reliance on technological solutions rather than on addressing the wider transport problem itself. Local action on air quality is never likely to be successful within the context of national policies that allow, or even encourage, continual growth in traffic.

—  Air quality has not been effectively integrated within policies concerning transport, spatial planning or health at either local or national levels and this has led to it failing to be given due regard in these areas.

ABOUT THE AIR QUALITY MANAGEMENT RESOURCE CENTRE AT UWE, BRISTOL

1.  The AQMRC is based at the University of the West of England, Bristol and was formed in 1998. Between 1999 and November 2010, it held (in partnership with Air Quality Consultants Ltd.) a contract with Defra (and formerly with DETR) for undertaking management tasks in relation to the Local Air Quality Management process. These tasks included:

—  the appraisal of local authority Review and Assessment reports;

—  the management of archives of reports and Air Quality Management Area orders;

—  the maintenance of databases to record and track these documents and other elements and indicators of progress within the LAQM system;

—  the operation of a telephone, email and internet-based helpdesk service to help local authorities with their work; and

—  support in the writing and updating of official guidance for Defra and the Devolved Administrations.

2.  In addition to the LAQM contract with Defra and the Devolved Administrations, AQMRC has also carried out a wide-range of other LAQM work for UK local authorities. This has included carrying out and providing assistance for review and assessment work and air quality action planning, support and facilitation for consultation and engagement exercises with the public and other key stakeholders, and training provision to enhance capability and capacity, specifically for LAQM but also in related areas of air pollution, climate change, and land-use and transport planning. AQMRC has a significant research background based on air quality management funded by prestigious research organisations including ESRC, NERC and EPSRC. This has generated an extensive peer reviewed publications list, and has allowed the development of a renowned track record in supervising and examining PhD students in the field of LAQM. AQMRC was also instrumental in the design and development of the Institute of Air Quality Management in order to promote and support the increasing number of professionals working in this field.

3.  AQMRC are internationally recognised for their leadership in the field and have been involved in a number of major international projects. The group has also had significant involvement in the promotion of the UK LAQM Framework as good practice in a range of contexts, including the EU Framework V INTEGAIRE (Integration of Environmental Governance and Air Quality in Europe) project, the provision of support for the development of air quality capacity in Bangkok Metropolitan Administration, and in the development of the South African National Framework on Air Quality (which used the UK system as a basic model).

4.  The AQMRC is a part of the Institute for Sustainability, Health and Environment (ISHE). This is an Institute comprising a wide-range of research groups covering key areas of research into: sustainable communities and the built environment; public health and well-being; and environmental sustainability.

Causes of particulate and NO2 air pollution in the UK and how these can be reduced most effectively

5.  The cause of air pollution problems in the UK are predominantly emissions of pollutants from road traffic within environments where there is poor dispersion of pollution and exposure of members of the public.

6.  Efforts to reduce pollution from vehicle tailpipes is not working, and is becoming increasingly ineffectual with each new Euro Standard.

7.  It is generally estimated that 50% or more of PM10 related to vehicles is associated with resuspended road dusts. Particularly as PM from exhausts, and tyre and brake wear is reduced this will become a much more significant source. Therefore measures to actually reduce road speeds and flows will become more effective.

8.   Problems with nitrogen dioxide are often associated with very low flows of traffic (sometimes <5000 vehicles per day) in narrow streets in small urban locations.

9.  Significant efforts need to be made to control and reduce levels of motorised traffic in built-up areas; this can only be done through aligned efforts at national and local levels.

Impacts on health and the environment from particulate and NO2 pollution, and how these should be measured

10.  There is not necessarily a problem with how impacts of air pollution are measured, so much as how the measurements are reported. Despite increasing evidence regarding he impacts of air pollution on health (which have shown previous estimates of the impacts to be significant underestimates) there has been little attempt to effectively engage the public over this issue.

11.  Defra last asked a question on air quality in their Quality of Life survey in 2001[33]. The response indicated that air quality was the most important of the government's environmental indicators for sustainability with 95% of respondents rating it as either Very or Fairly Important. There is little evidence that the government has taken up this opportunity for engaging the public.

12.  Within public engagement work done by AQMRC it is common to find air quality rated higher than climate change as a priority amongst local people, yet this is rarely reflected in messages from national government. This is something that potentially endangers the ability to take effective action on both issues.

13.  One problem that is apparent in the recording and reporting of pollution is the discrepancies between modelled pollution concentrations as calculated by Defra for the purposes of EU reporting, and the extent of problems evidenced through the LAQM process. Particularly with regard to PM10 the national modelling appears to significantly underestimate the scale of the problem in the UK with 59 local authorities in England alone having declared Air Quality Management Areas for PM10.

The effectiveness of the Government's strategy for improving particulate and NO2 air quality, and how that might be improved

14.   The Local Air Quality Management process as set out and developed by the 1995 Environment Act, 1997 Air Quality Strategy, and successive guidance and strategy revisions has been unsuccessful at delivering the necessary reductions in air pollution to meet domestic objectives and EU limit values because it was never designed to meet the eventual challenge.

15.   In the mid-1990s, following very successful reductions in pollution emissions from industry, through significant regulation, and from transport through the introduction of catalytic convertors, it was widely anticipated that future measures at a national level would be sufficient to ensure that air quality met necessary standards in all but a handful of locations.

16.   The Local Air Quality Management process can be divided into 2 parts: Review and Assessment and Action Planning. The Review and Assessment process was very successful in terms of identifying air quality problems in over 60% of Local Authority areas. A far greater problem than had ever been envisaged when the process was established.

17.   The current framework for action planning, where LAs are given the responsibility for devising an action plan and implementing it in relative independence from national government, and with no clear penalties for not achieving objectives, was never devised for a situation where air quality problems were so widespread, and is now out of date.

18.  With such extensive problems occurring, it is obvious that the problem, to some extent, exists at a national level and there is therefore a need to pay much closer attention to the interaction between national policies and local problems. One example of this is from the findings of the Sustainable Travel Town Demonstrations[34] that showed that whilst local efforts to reduce traffic might achieve a 9% reduction in trips by local residents, when overall traffic flows were examined, this was reduced to a reduction of only 2% in traffic flows due to the impact of non-local traffic.

19.  The LAQM Framework was developed at a time when there was a strong intention to try and tackle growth in road traffic (c.f. The 1997 Road Traffic Reduction Act, 1998 New Deal for Transport White Paper[35], and 2000 Ten Year Transport Plan). If these intentions had been successful there would have been much less difficulty for Local Authorities in developing and implementing effective local Air Quality Action Plans. However, in the context of national policies failing to effectively limit (and arguably encouraging) growth in transport, the ability of LAs to reduce air pollution is significantly constrained.

Potential effects of the Government's localism agenda and proposed reforms of public health provision on local authorities' capacity for tackling poor air quality

20.  As described above, we believe that the failure of UK air quality policy in achieving the UK objectives and EU Limit Values lies largely with national government and not local government. Whilst more power and influence at a local level is a good thing, a number of key issues need to be addressed:

21.  There must be sufficient statutory obligation on local authorities to tackle air quality to ensure that they prioritise it sufficiently to contribute effectively to the meeting of national targets, and to ensure that environmental protection doesn't become an option, leaving the protection of the health of the most disadvantaged to the chances of a postcode lottery. Local political priorities are rarely decided by the disadvantaged who most often suffer the ill-effects of air pollution.

22.  Local action must take place in the context of national policies that support local action and work in the same direction. It is no good cutting local authorities loose and expecting them to tackle the problems caused by a national failure to control road traffic growth.

23.  Local authorities need to be adequately resourced in order to carry out effective work in their areas. The first year of the new administration has seen swingeing cuts in local authority budgets that have resulted in a large number of air quality staff being made redundant. We consider it highly unlikely that this will lead to sufficient capacity in local authorities to undertake efficient action on air quality.

24.  Whilst much is being made of the proposed move of Public Health from the NHS to Local Authorities, particularly in respect of the potential for linking to environmental health issues, there are some significant problems to be overcome. The greatest of these is the issue of the two-tier Local Authority system in England. Over 50% of English LAs are district authorities rather than unitary, and therefore the proposed health service reforms will establish public health responsibilities at a county level, in a different organisation to environmental health which resides at the district level. Although there is some rhetoric regarding the fact that this will not be a problem and will in fact encourage cross-organisation working, current experience of working with local authorities at the district level suggests that pressures on staff and resources are so tight (resulting in the departure of many members of staff) that it is very hard to envisage how district environmental health departments will be able to actively engage with county level public health teams without clearly ring-fenced resources being allocated to them.

25.  AQMRC has been involved in a wide range of research and consultancy work that has involved examining or working across the cross-tier divide between air quality and transport officers, and the experiences generally indicate that inter council communication can form a serious hindrance to the development and implementation of effective policy.
