  2. Air quality impactsanalyzed for the CAFE baseline scenario Health: • Loss in life expectancy attributable to PM2.5 • Premature deaths attributable to ozone Vegetation: • Ozone damage to forests (AOT40) • Excess acid deposition to forests • Excess acid deposition to semi-natural ecosystems • Excess acid deposition to lakes • Excess nitrogen deposition All impacts shown for “no further climate measures” scenario, average results of 1997, 1999, 2000 & 2003 meteorological conditions

  26. Conclusions • With decreasing pollution, also impacts are expected to decline in the future. • However, problems will not be entirely resolved: • PM remains serious (~5 months life expectancy loss in 2020) • Ozone: • Remains a significant cause for premature deaths (Several 1000 cases in 2020) • Vegetation damage: Wide-spread violations of AOT40 critical level will prevail • Acidification: Will not disappear, mainly due to NH3 • Eutrophication remains unresolved
