Presentation Transcript

  1. Cost-effective measures to achieve further improvements of air quality in Europe (focus on key measures in the EECCA and Balkan countries) Based on presentation by M. Amann and F. Wagner at the 40th Meeting of the Task Force for Integrated Assessment Modelling Oslo, May 18-20, 2011 Presented by Janusz Cofala and Stefan Astrom

  2. Issue • The issue: • Identify a limited set of key measures that lead to cost-effective further improvements of air quality in Europe (to offer guidance to the negotiations on technical annexes) • Trade cost-effectiveness against simplicity • Starting point: • The scenarios of cost-effective emission reductions presented in the CIAM 1/2011 report (at TFIAM 39 and WGSR 48)

  3. Baseline projections of emissions in 2020 and the scope for reductions relative to 2000

  4. Ambition levels for further improvements of air quality in Europe (gap closure concept) Percentage gap closure for the impact indicators for the scenarios discussed Scope for gap closure – the difference between the effect in the Baseline 2020 and the MTFR 2020 scenarios

  5. Approach We applied a hybrid approach to identify a (subjective) set of key measures: Identify the set of cost-effective measures of the mid scenario Rank measures by their emission reduction potential in the EMEP region Choose a sub-set of measures that achieves a large fraction of emission reductions, e.g., measures that achieve overall reductions of the Low* scenario Remaining reductions that are not achieved by these measures could be subject to national emission ceilings

  6. Priorities for cost-effective emission reductions in the CIAM1/2011 report

  7. Cost-effective PM2.5 reductions in the mid scenario Low*

  8. Cost-effective NH3 reductions in the mid scenario Low*

  9. Cost-effective SO2 reductions in the mid scenario Low*

  10. Cost-effective NOx reductions in the mid scenario Low*

  11. Cost-effective VOC reductions in the mid scenario Low*

  12. The smallest set of measures to achieve the emission reductions of the Low* scenario in the EMEP region All these measures are in addition to the current legislation in each country

  13. Effectiveness of the selected measures(emissions, costs and effects relative to Low* scenario)

  14. Key measures for non-EU countries – SO2

  15. Key measures for non-EU countries – NOx

  16. Key measures for non-EU countries – PM2.5

  17. Key measures for non-EU countries – NH3

  18. Conclusions • A set of 15 measures has been identified that achieves Europe-wide the emission reduction of the Low* scenario. It involves largest reductions for PM2.5 and NH3 emissions (relative to baseline) • Priority pollutants/measures: • Non-EU: PM2.5 (industry) and SO2 (power plants) • EU-27: NH3 • and, to a lesser extent, in both groups on NOx and VOC. • This a subset of the cost-effectiveness measures to achieve the mid scenario, but not necessarily the most cost-effective set to attain the impacts of the Low* scenario. • In particular, if applied uniformly in all countries, such a sub-set would ask for measures in countries where they might not be cost-effective. • However, the identified measures might guide negotiations on sectors to be included in technical annexes of the protocol
