  3. What are the impacts of air pollution according to different scenarios of the Gothenburg protocol? TF measurement & modelling (MSCW, MSCE) ICP modelling and mapping Eutrophication ICP forests Acidification ICP waters ICP integrated monitoring TF IAM Ozone ICP vegetation ICP materials Multi-pollutant TF health JEG dyn mod

  4. Projections/scenarios available • NAT 2000: Historic data (partly Eurostat) • NAT 2020: Assumed national emissions (reported from the countries) • PRI 2020 and 2030: Projections (mainly) by PRIMES – an emissions energy consumption model • MFR 2020 – Maximum feasible reduction plan – how much is possible to reduce with present day technology • Data as available in October 2010. Update is on-going. Data provided by TF IAM / CIAM and MSCW

  5. Eutrophication ICP IM: Decrease of impacts is expected at various sites • The number of sites impacted decreases by about 20% in 2020 compared with baseline (70% with MFR) • The magnitude of the impact is reduced by about 40% with baseline in 2020 (80% with MFR) Number of sites protected /not protected with respect to critical loads for eutrophication for terrestrial ecosystems Average exceedance of the critical loads for eutrophication for terrestrial ecosystems

  6. Eutrophication ICP M&M: modelling at european scale confirms sites previsions CCE Status report • % areas at risk of eutrophication Accumulated Average Exceedance of critical loads for eutrophication

  7. ICP Waters: dynamic modelling shows recovery… and its limits Good match of modelled and monitoring data Conclusion (with NAT2020): ANC goes over ANC limit and levels off Bad years, acidification may occur NAT, PRI are equivalent as far as water acidification is concerned Acidification Highly sensitive sites will not recover even under MFR.

  8. Ozone ICP Vegetation:Ozone is of concern for food security POD6 (mmol.m-²) = phytotoxic ozone dose NAT2000 NAT2020 The magnitude of the impact will be reduced The areas (intensely) impacted are reduced But the impact will still occur in a large part of Europe Ozone impact on wheat production

  9. Multi-pollutant ICP Materials: Effects on materials will decrease but will not disappear by 2020 NAT2000 NAT2020 MFR2020 More intense effects are expected in urban areas than shown on maps.

  11. Overall conclusions • Similar observations from all groups and for all effects: • Area impacted decreases • Magnitude of impact decreases Acidification Eutrophication Ozone Multi-pollutant underestimated

  12. Conclusions (EB.AIR/WG.1/2011/3) Eutrophication • Monitored and modelled indicators indicate only limited improvements in eutrophication status. Reduction in N emissions remain insufficient to decrease areas and magnitude of risk for eutrophication. • Ozone impacts on ecosystems, food security and human health will remain very important. • Effects of air pollution on materials and health probably underestimated in urban areas with present models. • Decrease in emissions of S and N, and thereby decrease in deposition, have led to reduced surface waters acidification and a start of biological recovery in many acid sensitive sites. Improvement will continue. Ozone Multi-pollutant Acidification
