  1. T9.7 Multi-criteria evaluation of emission control strategies in semi-hypothetical case city archetypes Lian Scholes, Mike Revitt and Eva Eriksson

  2. What is multi-criteria analysis (MCA)? Decision-support tool Can incorporate non-financial information Performance matrix: possible solutions scored against range of criteria Can apply weightings to reflect stakeholder preferences

  3. Example matrix: DayWater MCC Weightings DayWater website: http://daywater.in2p3.fr/EN/

  6. ScorePP MCA matrix for Cd • Decision-making context: semi-hypothetical case city of EI • Options: ECS1 - 6 • Criteria: • Technical feasibility: available (1), under development (2), does not exist (3) • Technical efficiency: >95% (1), 80-95% (2), <80% (3) • Costs: <100M€ (1), 100M – 1000M€ (2), >1000M€ (3) • Environmental impact: results of the SFA • Allocation of scores – pollutant and context specific • Development of weights – this afternoon’s task!

  7. Matrix for Cd: assumptions made (1) • EI – emerging economy building technological and institutional capacity, elevated background levels of Cd • ECS1 - Baseline • WWTP services 90% of the population • IWW is 468M m3; 3% is BAT treated • 0.005% (2.5 ha) covered by stormwater ponds • All systems paid off so only O&M costs • ESC2 - Legislation • 100% connection to WWTP • BAT applied to 12% IWW

  8. Matrix for Cd: assumptions made (2) • ECS 3 – ECS2 + Voluntary initiatives - successful campaign to reduce use of Cd in artists’ paints • ECS 4 – ECS2 + BAT applied to 100% IWW • ECS5 – ECS2 + surface area covered by range of stormwater BMP types increased to 0.05% (25 ha) • ECS6 – ECS2 + Advanced WWT applied to 50% of WW

  9. Matrix for Cd in EI: ‘raw data’

  10. Matrix for Cd in EI Scores: range from 1 (best performance) to 3 (worst performance) Order of preference: Advanced WWT and Stormwater BMPs BAT and Voluntary Initiatives

  11. Matrix for Cd in EI Order of preference: Stormwater BMPs Advanced WWT Voluntary Initiatives BAT

  12. Matrix for Cd in EI Order of preference: Advanced WWT BAT Stormwater BMPs Voluntary Initiatives

  13. MCA – pros and cons PROS Structured, traceable and auditable analysis Copes with large amounts of data/information in differing forms and reporting units Can incorporate a variety of stakeholder interests An understandable communication tool CONS Dynamic problems simplified Is it too subjective? Static picture: lacks time dimension How are outcomes to be interpreted? Best or preferred option need not necessarily be that which provides the most e.g. cost-benefits
