  3. Organization of the Convention

  4. The Protocols • Increase ambition levels stepwise • Implementation of and compliance with Protocols in force • 1985 and 1994 Sulphur Protocols • 1988 NOx Protocol • 1991 VOC Protocol • 1998 Heavy Metals Protocol • 1998 POP Protocol • 1999 Gothenburg Protocol • multi-pollutant multi-effect • review process expected to be initiated by EB in December

  5. Draft conclusions from effects workshops in 2005 • Dynamic N processes; Brighton, UK • several biogeochemical models for various uses • empirical and mechanistic biodiversity impacts • Ozone; Obergurgl, A • recommends ozone flux method for ecosystems • no thresholds • for (semi-)natural concentration (AOT) at this stage • generic/model species for risk assessment in IAM • Nitrogen cascades; Braunschweig, G • state of knowledge on links and pathways • separation of NO3 and NH4

  6. Working Group on Effects, 2005 • Effects-based emission reduction strategies • New [draft] long-term strategy • New critical and target loads • acidification (CL, TL) • eutrophication (CL) • heavy metals (CL; Pb, Cd, Hg) • Cooperation between CCE and CIAM • Importance of the EECCA region (Eastern Europe, the Caucasus and Central Asia)

  7. Topical issues • Expected 1999 Gothenburg Protocol review • role of particulate matter (PM) • harmonized land use data • Improved emission and abatement data • uncertainties with primary PM • New information on effects • dynamics of acidification (recovery process) • ozone flux approach • biodiversity • Awareness of CAFE/NECD process
