Findings have been reported in CIAM Reports to the Working Group on Strategies and Review
Activity projections presented to WGSR42
Decision of WGSR41: Energy projections should include climate policies.
National projections with climate policies are currently unavailable.
Activity projections presented in CIAM Report 2/2008 to WGSR42:EU-27:• PRIMES energy projection that meets the targets of the
EU Climate and Energy Package (as in NEC Report#6)• National agricultural projections submitted to CIAM
Other Parties:• Latest available projections available at CIAM• Most date back to 1996• No responses received to requests from WGSR

Environmental impacts
Impact indicators:• Loss in statistical life expectancy attributable to PM2.5• Ecosystems with nitrogen deposition in excess of critical
loads (using ecosystem-specific deposition calculation)• Forest and catchment areas with acid deposition in excess
of critical loads • Cases of premature deaths attributable to ozone
Assumed boundary conditions:• Emission from ships: without recent MARPOL proposal• Hemispheric ozone: +2.4 ppb in 2020• Five-years meteorological conditions

Uncertainties and sensitivities
• Baseline projections are sensitive towards– Underlying activity pathways:
Assumptions about employed activity pathways have received only limited review by Parties
– Assumed implementation of national legislation: Conservative assumptions have been used for EECCA countries.
• Assumptions on boundary conditions– Implementation of additional measures for ships could result in
significant lower environmental impacts
• If baseline projections should serve as starting point for negotiations, above assumptions must be shared by Parties.

Two emission scenarios for non-EU countries that have not ratified the Gothenburg Protocol
• Baseline projection: – No add-on emission controls except for TSP from stationary
sources
• “With measures” scenario:– FGD for new and retrofit of 50% of old plants in 2020– Low sulphur fuels (1% heavy fuel oil, 0.1% light fuel oil, 0.05%
diesel
– Industrial processes: -50% SO2 , -40% NOx, and current EU PM emission standards for new Member States
– Primary NOx measures for boilers
– Euro 4/IV for diesel and gasoline vehicles– Improved electrostatic precipitators for large boilers

Potentials of major control measures compared to 2020 baseline projection
• FGD for new plants: -40% SO2
• 0.05% S diesel: -10% SO2
• Euro-4 for passenger cars: -13% NOx, -2% PM2.5• Euro-IV for heavy duty vehicles: -8% NOx, -4% PM2.5
• EU PM emission limit values for new Member States for stationary sources: -16% PM2.5
• In 2020, implementation of these measures would reduce health impacts from PM by 40 percent.
• In addition, major health improvements would result from a phase-out of solid fuels in households

Assumptions on boundary conditions for which advice from EMEP SB would be appreciated
• Background ozone 2000-2020: +2.4 ppb?
• 5 yr meteorological conditions (1996-1997-1998-2000-2003) for source-receptor relationships?
• Other suggestions?
