CAFE Directive
• Commission Proposal in September 2005• European Parliament 1st reading
September 2006• Adoption 21 May 2008• Entry into force: 11 June 2008
EU Air Quality Management CAFÉ Directive
• Health based limit values for concentrations of main pollutants.
• These to be applied universally: to Integrated Pollution Prevention and Control (IPPC), Environmental Impact Assessment (EIA) and for specific requirements of Air Quality Management Framework.
• Requires identification of agglomerations/zones for detailed assessment. Population over 250,000, densely populated or industrial zone
EU Air Quality Management CAFÉ Directive
• Specifies number of ambient air quality monitors required for zone/agglomeration of given size.
• Member states must list all places where pollutants exceed limit values (plus margin of tolerance)
• Improvement ‘action’ plans and programmes required for zones of exceedence – development of these requires air quality modelling.
• Exceedence of short term thresholds (NOx, SO2)
requires immediate action – air quality forecasting
• Public information
EU Air Quality Management CAFÉ Directive - II
Attainment scheme
Limit value
Time
Attainment dateDirective comes into force
Above margine of tolerance: annual report and plans or programmes to improve air quality sent to EC
Between limit value and margin of tolerance: annual report to EC
Below limit value: annual report to EC, Good air quality maintained
Margin of tolerance
New Directive key elements
• Existing legislation merged into a single directive (except for the fourth daughter directive)
• No change to existing air quality objectives
• New air quality objectives for PM2.5 (fine particles)
• Possibility for time extensions for complying with limit values
• The possibility to discount natural sources of pollution
Air quality objectives for PM2.5
5 objectives for PM2.5
• Target and limit value– 25 μg/m3 annual average to apply everywhere .
– Target value in 2010, limit value in 2015
– Indicative limit value of 20 μg/m3 in 2020, to be confirmed at review
• Exposure (based on national average exposure indicator)– Exposure concentration obligation 20 μg/m3 in 2015
– Exposure reduction target to reduce national average measured urban background concentration 0-20% between 2010 and 2020 subject to later review where differentiated MS legal objectives to be proposed
Compliance problems (Article 22)
• Attainment date can be postponed for particular pollutants:– NO2, benzene - maximum postponement up to
2015
– PM10 – until June 2011
• Conditions – air quality plan which obligatory has to at least consider a list of measures (Annex to the Directive)
• LV in force, but at LV+MoT level
Compliance problems (Article 22) – II
• PM10
– Attainment date already passed
– All appropriate measures taken to reach compliance in 2005
– External reasons prevented compliance (transboundary, climatic conditions, dispersion
– Compliance demonstrated by new deadline
• NO2, benzene– Attainment date not yet arrived
– 2010 can not be reached (measures taken)
– Compliance demonstrated by new deadline
Addressing man-made pollution
• Existing provision to deduct natural events generalized to natural contributions– Natural sources: volcanic eruptions, seismic
activities, geothermal activities, wild-land fires, highwind events, sea sprays or the atmospheric re-suspension or transport of natural particles from dry regions
– Deduction needs to be well justified
– Further source apportionment mostly required to be able to use this provision
• Guidance in development
Addressing man-made pollutionII
• Contribution from re-suspension
• Exceedances of PM10 attributable to winter-sanding or -salting of roads
• Deduction needs to be well justified
• Reasonable measures taken, air quality plans
• Guidance in development
Where limit values apply?
• Specific list of locations where compliance with limit values related to health is not to be assessed:– On the motorway
– Where no access and no permanent habitation
Limit values apply everywhere!
Protection of vegetation and biodiversity
• Critical levels (SO2 and NOX) – Annex XIII
• “Level” – shall mean the concentration of a pollutant in ambient air or the deposition thereof on surface in a given time
• Critical loads important for the assessment under the Habitats directive
