Particulate Matter, the Thematic Strategy & the National Emissions Ceilings Directive UNECE WG PMBerlin May 2005 Duncan Johnstone Clean Air & Transport Unit DG Environment
Important Caveats • The proposed content of the Thematic Strategy on air pollution is currently subject to the internal decision making procedures of the Commission. • There is no guarantee that the there will be a strategy or that interim environmental objectives will be established as foreseen.
CAFE & the Thematic Strategy • The CAFE Programme has undertaken the technical work for the Thematic Strategy on Air Pollution. • Technical Work has looked at environmental/health objectives related to human exposure to PM. • The Thematic Strategy “will” establish Community objectives for the protection of human health from PM. • A Twin approach will be taken to make progress towards these objectives • Ambient air quality management objectives (local/national) • Revision of the National Emissions Ceilings Directive (national/transboundary)
Air Quality Management • Revision of ambient air quality legislation • New “Cap” concentration for PM2.5(roughly equivalent to PM10 LVs) • Exposure reduction for PM2.5 based upon • Average of measured concentrations in urban background locations • Reduction in the average concentration between 2010 and 2020 that varies according to baseline concentration in 2010 (3-year rolling mean) as 1.5% per µg/m3
Revision of the NECD • PM2.5 also comprises components that are transboundary in nature • Components comprise 1° and 2° aerosol • 2° aerosol tackled by revised ceilings for SOx, NOx, NH3. • 1° aerosol tackled by new ceiling for emissions of primary particulate matter • National emissions ceilings linked back to the interim environmental objectives in the Thematic Strategy but using refined calculations.
