1. DRAFT PLANS TO
IMPROVE AIR QUALITY
– THE IAQM’S VIEW
23 October 2015, Roger Barrowcliffe

2. • European Commission infraction proceedings, 20 February 2014
• Supreme Court Ruling, April 2015
• Government spending review, 25 November 2015
• Deadline for reporting to Commission, 31 December 2015
• Euro 6c (RDE ) comes into force, 2017????
CONTEXT

3. • Are the proposed measures sufficient to
meet the requirement to achieve
compliance as quickly as possible?
• If not, what additional measures might
reasonably be taken by government at all
levels to meet this requirement?
REQUIREMENTS

4. WHAT’S THE PROBLEM? – HISTORICAL EMISSION TRENDS

5. WHAT’S THE PROBLEM?
DEFRA’S VIEW OF NO2 CONCENTRATION TRENDS

6. NOX AND NO2 CONCENTRATIONS AT HILLINGDON, NEAR THE M4
NOx
NO2

7. EXTRACTING THE DIESEL CONTRIBUTION AT THE HILLINGDON SITE
(MALBY et al, ATMOS ENV, 2013)

8. WHAT’S THE PROBLEM?
– THE CONTRIBUTION OF THE DIESEL ENGINE

9. BY THE WAY, THIS IS NOT A SURPRISE….
QUARG report 1993
Diesel vehicle emissions and urban air quality
‘In the view of the Review Group, the impact
of diesel vehicles on urban air quality is a
serious one. Any increase in the proportion
of diesel vehicles on our streets is to be
viewed with considerable concern unless
problems of particulate matter and nitrogen
oxides are addressed .’

10. WHAT’S THE PROBLEM?
- A LOOK AT SHEFFIELD AND ITS ROADS

11. WHAT’S THE PROBLEM?
- SHEFFIELD SOURCE APPORTIONMENT

12. WHAT’S THE PROBLEM?
DEFRA’S VIEW OF THE FUTURE IN SHEFFIELD

13. WHAT’S THE PROBLEM?
- DEFRA’S VIEW OF THE FUTURE IN SHEFFIELD

14. • ‘promote smarter travel choices’
• ‘improve engine performance of commercial diesel vehicles’
• ‘mitigate the impact of the M1 motorway’
• ‘ECO Stars’
• ‘infrastructure for low emission vehicles’
• ‘hydrogen vehicle re-fuelling infrastructure and vehicle trial’
• ‘PM2.5 communication and action strategy’
• ‘improvements to Rotherham bus services’
• ‘promoting green infrastructure’
• ‘clean energy generation from transport assets. Photovoltaic
installation, wind turbines, timers in bus shelters’
SOME SELECTED MEASURES FROM DEFRA’S ACTION PLAN FOR
SHEFFIELD

15. • Little at a national level, except for existing
commitments by OLEV
• Much expected of local authorities
• Only new initiative is Clean Air Zones –but
implementation is left to local authorities
• Repetition of existing policies and plans in sectors such
as industry, aviation, railways an shipping.
• In summary, little that is new or focused on the main
problem, ie emission of NOx from diesel engines in urban
areas
PROPOSED MEASURES

16. • Any fiscal measures related to fuel tax and the neutrality
between gasoline and diesel
• Removal of diesel cars from the fleet through a scrappage
scheme
• An outright ban on the use of diesel cars in areas of non-
compliance
• Any programme of independent or Govt testing of ‘real world’
emissions of Euro 6 vehicles to inform consumers
WHAT’S NOT PROPOSED

17. • Do the plans meet the requirements?
• NO
