National Air Quality Strategy: Securing a Healthy Environment

This document outlines DEFRA's efforts to monitor and improve air quality in the UK, focusing on key pollutants like NO2 and PM10. It discusses implementing the Ambient Air quality Directive, Euro standards for vehicles, and additional actions needed to reduce pollution levels. DEFRA aims to work with local authorities to implement Low Emissions Strategies and Zones for better air quality.

  1. LES – A National Perspective Martin Williams Atmospheric Quality and Industrial Pollution DEFRA 12 May 2009

  2. Main sources road transport National Air QualityNatural Environment PSA 28 ‘Secure a healthy natural environment for today and the future’. • Air free from harmful levels of air pollution • Meet air quality objectives for key air pollutants in the AQS as illustrated by trends in measurements of two of the more important pollutants which affect public health: particles and nitrogen dioxide.

  3. Annual average concentration(µg m-3) for NO2 and PM10

  4. Implementing the Ambient Air quality Directive • Directive 2008/50/EC adopted June 2008 Must implement by June 2010. • Preparing draft regulations and expect to consult later this year. • Will set new control framework for PM2.5 • Includes facility for compliance flexibility on limit value deadline for PM10, NO2 and Benzene (we are applying for PM10 and NO2 only) • Applied for PM10 time extension 24 April 2009 • Compliance deadline for NO2 is 2010 extension available until 2015 • Must demonstrate a robust case to European Commission • Most major member states are expected to apply over the next year/18mths

  5. Euro Standards for Light Duty Vehicles

  6. Euro Standards for HGVs

  7. Exceedences (km of road length) 23km of exceedences in 2015

  8. Urban major urban roads, annual mean roadside NO2 concentration, 2007 (g m-3)

  9. LAs with current AQMAs LAs with AQMAs by Pollutant

  10. Buses HGVs Local Traffic Background

  11. Further Actions • Need to refresh approach to delivery of AQS • Accelerate impact of national measures • Budget 2009 announce commitment to encourage uptake of Euro VI HGVs and Buses and will look at ways of encouraging Euro 6 cars • Revisit feasibility of measures and use in focused way eg • Retrofitting – (eg HGVs/bus fleets in target areas), • Low Emission Zones

  12. Working with Local authorities towards Low Emissions Strategies • Coordinated effort at National and local level is needed • Need to focus resources on those areas with greatest levels of pollution • Defra reviewing the effectiveness of LAQM – how can we improve delivery?

  13. Defra Ministers convening a ‘Summit’ with key LAs – summer 2009 • Will involve transport/planning and environment players • Will stress the importance of LES and LEZs • Will also need to consider a range of measures
