Background information• Stakeholder Day is part of Stakeholder Consultation
• Outcome will be documented (note taker) and considered for modifications of the MRG
- List of key messages
- List of key problems during implementation
- List of key proposals for modification
• Revised Guideline expected to be adopted by the end of the year 2006

Overview
• 31 questionnaires – 14 by industry associations, 17 by installations - and 3 position papers / other written comments received
• Comments on cross-cutting as well as on technical issues

Comments – General
• Accuracy requirements need to be balanced against cost effectiveness
• Flexibility of the MRG depend very much on national interpretation -> Harmonisation is needed
• Introduce lower accuracy requirements for smaller sources (i.e. fuel and material flows)
• Allow more flexibility towards integration in existing monitoring system at plant level

Comments – ISO 17025
• Use of ISO 17025 accredited labs for analyses has no added value but leads to considerably higher cost for accreditation of in-house labs or use of external accredited labs
• Allow ISO 9000:2000 or ISO 14001 as alternatives to ISO 17025

Comments – Measuring equipment
• Typical uncertainty margins can often not be maintained during long-term operations of the clinker burning process
• Differentiation between measuring accuracy at manufacturer and accuracy in operation is necessary

Comments – Emission Factors I• Suggested simplified system for fuel EF:
o Fixed emission factors for standardised fossil fuels, with NCV determined by analyses (solid), fixed value (liquid), given by supplier (gaseous) respectively
o Fixed emission factors for waste fuels where statistical data is available, otherwise determined through analyses at least once a year by an accredited laboratory, with NCV generally determined through analyses at least once a year by an accredited laboratory

Comments – Emission Factors II
• Methods used in the MRG require a large number of measurements – allow simplified approach
• Allow country-specific standard value for process emissions: Emission Factor between 0.520 and 0.550 t CO2 / t cement klinker

• Integration of EU-ETS monitoring into existing monitoring procedures
• Determination of emission factors for fuels
• Determination of emission factor for process emissions
