1. EU Emission limits for road vehicles
Günter Hörmandinger
European Commission, DG Environment, unit C.1 “Clean air and transport”
19 November 2004

2. Light-duty vehicles: current status
Directive 98/69/EC
Current limit values Euro-3
From 1 January 2005: Euro-4
M1 diesel:
CO (g/km)
NOx (g/km)
NOx + HC (g/km)
PM (g/km)
Euro-3
2000
0.64
0.5
0.56
0.05
Euro-4

0.25
0.3
0.025

3. Euro-5: some key issues Particulate matter from diesel:
Mass reduction
Ultrafine PM
PM number counts: presumably not for this proposal on Euro-5
NOx from diesel:
Availability of aftertreatment technology
How much reduction without aftertreatment
A further Euro-6 limit value? (presidency conclusions on sustainable road transport by NL presidency, following Council on 14 Oct 2004)

4. Euro-5 Scenarios for LDV diesel

5. Euro-5 Scenarios for LDV petrol

6. Euro-5: current activities
Questionnaire sent out to stakeholders & responses received earlier in 2004
Currently a validation panel (3 experts) summarises and validates; report by end November
Result will be data on:
The technologies needed to meet scenarios
The on-cost of these technologies beyond Euro-4 compliance
This will be used in modelling in the context of CAFE
A proposal on Euro-5 planned for the first half of 2005

7. Heavy-duty vehicles: current status
Euro-4 from 1 October 2005
Euro-5 from 1 October 2008, already decided
Final provisions for Euro-4 currently being prepared, including OBD and in-use compliance
Key issue: how to make Selective Catalytic Reduction (SCR) work in practice
Urea infrastructure
Anti-tampering and preventing abuse

8. Heavy-duty vehicles: limit values
Directive 1999/96/EC
Current limit values Euro-3
From 1 October 2005: Euro-4
From 1 October 2005: Euro-5
CO (g/kWh)
NMHC (g/kWh)
CH4 g/kWh
NOx (g/kWh)
PM (g/kWh)

ETC test cycle:

9. Euro-6 for HDV: key issues
Further reduction of NOx emissions (in view of US 2007 standards)
Particulate matter (same issues as with LDV)
Real-life emissions

10. Scenarios for heavy-duty vehicles

11. Timetable for Euro-6
Questionnaire was sent out this year, responses have been received
Validation panel will scrutinise from beginning 2005
A proposal to be made later in 2005
