Cleaner Air for ScotlandScotland’s first air quality strategy
Dr Colin GillespieScottish Environment Protection Agency
Cleaner Air for Scotland
• Strategy Development
• National Modelling Framework
• Aberdeen Project
• Scottish Air Quality Dataset Project
Air quality hits the news…
• More local authorities declaring AQMAs
• Many local authorities have long established action plans with a wide range of measures, but progress in improving air quality is slow
• Measures with the biggest potential impacts tend to be expensive and/or presentationally difficult – Low Emission Zones, congestion charging, large scale modal shift from private vehicles to public transport or active transport
• Aberdeen, Edinburgh and Glasgow have all completed/are undertaken LEZ feasibility studies – but no LEZ yet in Scotland despite widespread adoption in Europe
Background
Cleaner Air For Scotland
Launched at theAnnual STEP Conference4th November, 2015
3 main components to the strategy…
Main components to the draft strategy
Policy alignment
Assessment process
Working framework
CAFS – Modelling & Monitoring Working Group
The Working Group was intended to:• Provide comment on the Strategy and guidance on how to progress the Strategy further towards publication• Help drive delivery of the Strategy actions beyond publication
Scope of the group – Covering the development of the National Modelling Framework, including the regional assessment process and the Modelling approach, whilst considering the wider monitoring requirements to support the Strategy. Develop the national Modelling Guidance, including the identification of data requirements for undertaking the modelling framework.
National Modelling Framework
Regional NMF· Identify cross-regional issues – based on land use focusing on
Strategic Planning AreasLocal NMF· Identify potential problem areas, causes and potential solutions
Regional NMF model
Looked at other approaches…
• Based on the Netherlands approach
• Regional model to assess contributions from planned development (size dependent)
• Model updated on a regular basis • LAs provide planning information • LAs and TS provide traffic data
Learning from National Flood Risk Assessment approach…
• Engagement – success is dependent on partners working together
• Sound Science – standard approach to gathering data, detailed modelling to support development of actions
• Prioritisation – developing a joint decision making process between responsible bodies that prioritises actions for maximum benefits
• Support – Scottish Government support for the proposed process (CAFS)
Local NMF Model Using Aberdeen as our pilot study
Translate Data Information Evidence Decision
process
The main focus is on data and not the AQ model…
Data, data and more data – gathering the appropriate data
Data gathering• National traffic data collection project - two-tiered approach to collecting traffic data • Identify existing and gathering additional traffic data
Collecting different forms of traffic data will help to build the right picture, improving street-based emissions and traffic composition
Developing the national approach
Analyses and Visualise• Developed live and interactive visualisation tools through Spotfire• Initial data can be visualised – build on-line traffic profiles identifying busy roads and junctions in relation to traffic groups• Air model outputs can be scrutinised• Pull together a range of databases
Developing the national approach
Addressing uncertainties• Analysis tools are used to identify uncertainties• CFD models used to identify unique air flow issues• Additional data requirements feed in to the information loop
Beyond a paper report
Transform data/information into evidence• Provide interactive tools rather than paper-based reports• Develop scenario testing tools for developing actions• Promotes collaborative approach to problem solving• Promotes ownership of the actions developed
NMF will support the NLEF – working as afeedback loop
Ensuring the NLEF assessment has a robust evidence base to be used in the appraisal of access controls, such as;
– Low Emission Zones– Clean Air Zones– Additional actions
Public Air Quality Tools
Local Authority Reporting Tool
LA Reporting Tool
What’s required…
Ensuring a national approach is fully adopted…
– Close link between NLEF and the NMF– Develop service that LA can easily utilise without
restrictions– Provide a national service for LAs– Link to existing legislation– Provide access for both frameworks on existing web-based
tools– Provide resource that can be utilised by all – promotes
partnership working
