Understanding how transport choices are affected by the environment and health: views expressed in a study on the use of carbon calculators.

OBJECTIVES: To examine the influence that the provision of environmental information might be able to make on personal travel behaviour through analysis of the views of members of the public expressed in a study for the UK Department for Transport on attitudes towards carbon calculator tools. STUDY DESIGN: A three-stage qualitative survey taking an ideographic approach to analysing public attitudes to the use of carbon calculator tools in relation to making transport decisions. METHODS: Interviews and discussion groups with stakeholders, non-users and users providing extensive data that were analysed using the British Market Research Bureau's matrix mapping methodology. RESULTS: Despite considerable awareness of climate change as an issue, personal carbon emissions were not found to have much influence on personal transport choice, which could be seen as being dominated by issues of cost (both in time and money), comfort and convenience. CONCLUSIONS: The spatial and temporal dislocation of the cause and effects of climate change make it difficult to link the impacts of personal travel behaviour with specific activities. If environmental- and health-based information is to be provided as a lever to change travel behaviour, it may be necessary to provide information on issues such as local air pollution and personal health impacts in order to link wider benefits with a travel user's self-interest.

Local air quality management as a risk management process: assessing, managing and remediating the risk of exceeding an air quality objective in Great Britain.

Air quality is managed in Great Britain via an effects-based, risk management process designed to provide a dynamic solution to public health issues associated with elevated concentrations of seven specified air pollutants. This paper is concerned with an examination and evaluation of the process of Local Air Quality Management (LAQM) in Great Britain from the late 1980s to date as a risk management process. The statutory basis of LAQM process is provided by the Environment Act 1995. The Act provides a framework in which national and local actions are required to identify and remediate areas of poor air quality. Within this framework, the implementation of the process at national and local levels is considered, leading to an identification and assessment of risks in the formulation and implementation of air quality management policy and practice. Local Authorities began the process of Review and Assessment in 1999 and the first round of the process concluded in 2001. Following this, some 129 Local Authorities declared one or more Air Quality Management Areas (AQMAs). The Review and Assessment elements of the framework were subjected to an evaluation in 2001 and the essential elements of it were confirmed as fit for purpose. The evaluation led to a confirmation of the process of LAQM but also a simplification based on the experience of Round 1. Now, a two step process is required comprising of an Updating and Screening Assessment and, where a risk of exceeding an Air Quality Objective (AQO) is identified, a Detailed Assessment follows. The Government has identified a time scale for Review and Assessment through to 2010 and also introduced the requirement of a regular Progress Report in order that a Local Authority is able to address routine matters of air quality management. The risks inherent in epidemiological or scientific uncertainty are factored into the LAQM process at an early stage of the process and, by identifying the risks and subjecting them to regular review, the process provides a 'level playing field' across spatial and temporal scales. Whilst the process of LAQM described in this paper has been developed for Great Britain, the generic elements of the process are applicable to other countries challenged by air pollution problems which require both national and local action to resolve them.

Outcomes of the first round of local authority air quality Review and Assessments under the UK's air quality strategy.

In 1997, the UK government instigated the practice of Local Air Quality Management (LAQM) in the UK. This process is based on local authorities undertaking Review and Assessments of air quality within their areas. The first round of Review and Assessments have now been completed and represents the most extensive and coordinated analysis of air pollution ever undertaken in the UK, and probably in Europe. This paper takes a broad look at the outcomes of this process so far and identifies some of the key areas where lessons have/can be learnt both about patterns of air pollution in the UK and about the framework for investigating these that has been implemented under the LAQM regime. The process has led to a much higher number of local authorities finding problems with air pollution than initially expected. It has also challenged many assumptions about the significance of various pollutants and their sources.
