The Commission Euro VI proposal
• The proposal for a Regulation, rather than a Directive, is in line with the principles of CARS 21 to ensures full harmonisation across Member States.
• The ‘split level’ approach provides an effective means of dealing with the complexity of the technical requirements and test procedures.
• The proposal provides a thoughtful package of emissions limits with specific requirements for off-cycle emissions, OBD, production conformity, durability, roadworthiness and in-service conformity to be included through the comitology.
• The limit values proposed are achievable.

Euro VI comitology issues
• Work on the comitology needs to start as soon as possible to ensure that all details are in place for the start of Euro VI.
• Although Euro IV and Euro V are available in split-level format, the changes in procedures and requirements, together with referencing of UN-ECE procedures, will require substantial effort.
• Critical issues include (but are not limited to) – the definition of reference fuels (including use of biofuels),
– correlation values for the World Harmonised Test Cycles,
– particle number requirements.

Euro VI comitology – particle numbers
• The inclusion of particle number limits, as foreseen in the Commission proposal, is needed to ensure the use of effective particulate control technology.
• Methodology and limitsshould be defined as soon as possible to ensure implementationat the same time as other requirements.
• Appropriate technologiesallow around 3 orders of magnitude reductionin particle numbers. 1.00E+10

Introduction of world harmonised test cycle
• The proposal to include the World Harmonised Test Cycles is welcomed and can enhance European engine manufacturers’ lead in diesel technology worldwide.
• Correlation factors need to be established based on realistic technologies for Euro VI.

Summary on Euro VI proposals• Control of NOx and PM emissions will produce benefits
for European air quality. • The Euro VI proposals are achievable.• The comitology needs to be developed as soon as possible to
allow system developments to proceed. • Particle number procedures and limits need to be developed as
soon as possible to ensure concurrent implementation with other emissions requirements.
• WHTC correlation factors need to be established based on appropriate technologies.
• Early implementation of the technologies for Euro VI can assist in improving urban air quality to meet legislative targets for ambient air quality.
