2 Context Air quality and emissions subject to international and national observation and action WHO, OECD, UNEP, UNECE, CLRTAP and the Göteborg protocol, EU and national/regional legislation On EU level AQ and global emissions are regulated by: - The EU 2005 thematic strategy on air pollution (2005) - Emission caps: National Emission Ceilings Directive (DIR 2001/81/EC) - Local air quality limits: Air Quality Directive (DIR 2008/50/EC) Major global emission reductions were achieved from 1990 on Yet major incompliance still exists

3 Significant AQ exceedence persists (2010) Which causes serious health risks PM10 Loss in statistical life expectancy attributable to exposure to PM2.5 from anthropogenic sources (in months for year 2000) Annual average NO2 Annual average Source: EEA reports

4 .. Which causes serious health risks Loss in statistical life expectancy attributable to exposure to PM2.5 from anthropogenic sources (in months for year 2000) Health costs of air pollution: 23 Billion/year EU wide Premature deaths due to air pollution about /year i.e. 10 times the amount of deaths due to traffic accidents.

5 As a result: - High percentage of EU population exposed to air polluant concentrations above EU limit values, mainly on PM (33%), NO2 (5%), O3 (14%). - Exceedence values higher in relation with WHO air quality standards ( > 80% ) - Commission identifies incompliance with AQ legislation in many Members States. - Legal procedures ongoing against 17 Member States mainly on PM10, one on NO2. - More cases can be expected 5

6 Sources of air pollution and trends 6

7 Transport contributes considerably to air pollution Antwerp, NO2,

8 Evolution of NOx light duty emission limits in line with Regulation EC 715/2007 the Euro 5/6 regulation and preceding NOx Emission Limit (mg/km) Max. diesel Euro 3 ( ) Euro 4 ( ) Euro 5 ( ) Euro 6 ( ) Max. petrol

9 Evolution of PM10 emission limits (Light duty Diesel) in line with Regulation EC 715/2007 the Euro 5/6 regulation and preceding mg/km Euro 1 ( ) Euro 2 ( ) Euro 3 ( ) Euro 4 ( ) Euro 5 ( ) Euro 6 ( )

10 Emission of exhaust particulates, Heavy duty vehicles in EU (Euro VI contribution not included) Tonnes /year Källa: University of Thessaloniki/TREMOVE 2008 Following reduced emission limits and other Euro X measures, the PM 10 transport problem gets under control. We see PM concentrations decrease by 2020, The problem lays with NOx emissions

11 Why Do We Then Have a Problem? Current diesel cars are the main cause of NO 2 exceedence and are the main obstacle for reaching the standards set forward by the Air Quality Legislation Member States claim they cannot comply just because of the Euro5/6 legislation

12 The three main reasons for the divergence: 1. The depollution subsystem of the diesel engine as provided. 2. The current legal test cycle used for vehicle type approval, 3. Cycle beating

13 The three main reasons for the divergence 1) The diesel engine: high air intake, temperature NOx producer 3 way catalyst would not do the job Engine depollution like EGR (exhaust gas recuperation) works the best in low power conditions EGR is turned off when power is needed (acceleration, slopes, high speed) Sophisticated pollution debatement systems exist but were not provided under Euro 1, 2, 3,4, 5.

14 The three main reasons for the divergence 2) The test cycle used for type approval: Euro 5/6 legislations makes reference to normal conditions of use (i.e. no specific test cycle) for meeting regulatory criteria on the pollutant emission limits. An implementing decision has introduced a test cycle called NEDC in 2008 Commission shall monitor situation of RDE and amend test procedures, if necessary. If the test cycle does not deliver the regulatory objectives set by Euro 5/6 codecision regulation, it should be changed. Test cycle is short, very smooth, not representative of nowadays cars nor driving.

15 The three main reasons for the divergence 3) Legislation leaves possibility for "Cycle beating" during the type approval test A very repetitive and idealised cycle, set up for repeatability reasons invites for cycle beating. Cars computers can recognise test mode The current emission control is not representative for measuring real emissions in particular NOx. NOx emission in real world can be up to 15 times the regulatory emission levels over a 20 minutes real world test drive.

16 Amending the Euro 6 legislation Reminder: The Commission shall monitor situation of RDE and amend test procedures, if necessary. If the test cycle does not deliver the regulatory objectives set by Euro 5/6 co-decision regulation, it should be changed. An RDE expert group composed of MS Member States, industry, experts & Commission started in Tasks: Developing a real world emission measuring method Designing a vehicle test postcedure Presenting a proposal for a legal act amending Reg 715/2007 and subsequent. This work is in the final stage.

17 The retained Method for Real Driving Emission testing for i.a. type approval: Portable emission measurement sytems PEMS testing: put all measuring equipment on the car and run. Complexity of the operation: Boundary conditions, ambiant conditions and the driver s temperament Cold start issues Regeneration issues Fuel quality issues Origin of signals Plug in and hybridisation

20 Timing of the RDE (Real Driving Emissions) project (1) Euro 6 emission limit values have come into force on 1/9/2014. Legal proposal expected in December 2014, kick off Gradually phased in 2015 until : type approval based upon real world emission measurements.

21 Timing of the RDE (Real Driving Emissions) project (2) Further developments in 2015 for RDE measurement of non gaseous substances (PM, PN,..) Preparation (in 2015) of the regulatory phase to be in force from 2017 on. Setting up the full legal framework for follow-up and surveillance We are not against diesel, nor diesel cars: Technology to reach Euro 6 emission limits exists and is affordable

22 What is at stake if the Euro 6 process goes wrong? In December 2013 the Commision presented its Clean Air Package, containing a revision of two emission related directives (NECD & MCP). Short-term aim (2020) of the revision is to establish full compliance with 2005/2008 Air Quality legistation by at last. Long-term strategy (2030) whis is now launched aims at having no exceedence of the WHO AQ standards by 2030, reducing health effect by over 50%. If Euro 6 fails, neither target will be reached -> deadlock situation for the EU and the MS.

23 Conclusion: We face AQ problems and infringements. Member States say they cannot comply unless the RDE issue is resolved. The current emission issue is an obstacle for reaching better air quality and reaching the targets of the Air Quality Package. All technology needed to reach the Euro 6 Standards is available at reasonable cost. No choice but simply go forward and implement solid Euro 6 RDE provisions. Thank you for your attention
