Uncertainties Four types of uncertainties highlighted by the RAINS review team: Lack of scientific understanding Assumptions, simplifications etc. in the handling of data and the design of the RAINS compartment models Statistical variance in input data, etc. Socio-economic and technological development
(1) Lack in scientific understanding PM Health impacts Coal, oilWoodDiesel, gasolineOther Total PM2.5 emissions Black carbon CAFE baseline emission projections for PM EU-15 [kt]
(2) Model design Spatial resolution is critical Urban increment of PM2.5 (year 2000) Provisional City-Delta results (µg/m 3 ) Urban low-level PM2.5 emissions
(3) Statistical variance in data Inter-annual meteorological variability of PM Grid average concentrations, annual mean [µg/m 3 ] from known anthropog. sources excluding sec. org. aerosols. Calculations with emissions for the year 2000
(4) Uncertainties in socio-economic development Range of the 3 CAFE baseline emission projections [kt] EU New Member States
The wider context Long-term trends Hemispheric background
Long-term trends of EU-25 emissions “with climate measures”, relative to year 2000 [= 100%]

Conclusions Emissions will further decline But: Air quality remains threat to human health Sustainable conditions for vegetation will not be reached Relevance of sources will change Ship emissions will surpass those from land-based EU sources Energy projections will influence future emissions and emission control costs
