6. © 2 0 06 APMGDiapositive 6 ALCAN COMMITTED TO SUSTAINABILITY Alcan’s aspiration is to be an “industry shaper” Being ahead of the curve and establish new standards

7. © 2 0 06 APMGDiapositive 7  No company can be sustainable over the long term if it is not economically viable  No company can be economically viable in the 21 st century if it fails to accept its social and environmental responsibilities Leadership from the top Dick Evans: managing the business in a way that supports “Alcan’s governing objective of maximizing value…in a sustainable way”, with Alcan’s commitment to sustainability…the glue that runs throughout our integrated management system. What does “Sustainability” Mean at Alcan?

8. © 2 0 06 APMGDiapositive 8 Committed to Sustainability Alcan’s sustainability framework directly supports the governing objective and instils the highest standards for social responsibility, and environment, health and safety Alcan’s 8 key topics related to sustainability: Energy Climate Change Natural Resource Management Life Cycle Product Stewardship Community Development Well-Being Environmental Releases Industry Shifts

AP50 is the next generation smelter technology – to be piloted in Saguenay, Quebec.  Alcan has set an ambitious target of developing a 20% more energy efficient and environmentally friendly cell through the accelerated introduction of new innovative technologies.

24. © 2 0 06 APMGDiapositive 24 Importance of primary and recycled Aluminium production in EU

25. © 2 0 06 APMGDiapositive 25 Global Policy Leadership We have made much progress and Alcan and with the other International Aluminium Institute members (70 percent of global production) We believe, however, that more must be done to encourage aluminium industry progress, everywhere We are encouraging the industry to adopt even more ambitious voluntary targets and to consider development of a global sector agreement

26. © 2 0 06 APMGDiapositive 26 Policy context European aluminium producers support global market-based mechanisms to: accelerate real GHG reductions, with existing technology; stimulate the development of new emission abatement solutions; and, give business the flexibility to adapt its GHG reduction plans in time and in geographical implementation The world, however, is far from an effective global system and remains divided on how best to tackle climate change Industry welcomes sound approaches to reduce CO2e emissions and, generally, views the AP6 and Kyoto plans as complementary

27. © 2 0 06 APMGDiapositive 27 Competitiveness challenges Even though excluded from the EU ETS, our industry is severely impacted by the CO2 cost in the price of electricity We can not pass through any of these costs This threatens further dislocation, for no environmental gain Two independent reports have assessed the impact of EU ETS on production costs for aluminium -Carbon Trust – European ETS: Implication for Industry Competetiveness (2004) – Conclusion: €25/t CO2 will increase marginal production cost by 13,1% -International Energy Agency – Industrial Competetiveness under the EU ETS (2005) – Conclusion: €30/t CO2 will increase the cost by 11,2% Rather than regional constraints a global sector approach/agreement would be a better means to make progress; especially, to bring in those regions of the world which do not yet participate

28. © 2 0 06 APMGDiapositive 28 Aluminium Sector Suitability Homogeneous sector Facilitates the development of sector-wide baselines Significant variations in emissions from the same technology type could be closed with best practices Standard technology : two major electrolytic technologies, with a couple of major sub-grouping in each Söderberg technology (older, smaller and less efficient) Prebake technology Most new investments generally use best available technology Accelerated adoption of BAT would reduce emissions, significantly, while meeting ever increasing demand

29. © 2 0 06 APMGDiapositive 29 A Sector ‘Agreement? Target primary production (80% of emissions) Baseline Setting: Global BAT for new facilities Global top X% for older technology types Procedures to ensure credits for results supplementary to BAU Definition of the sector and its boundaries Indirect emissions could be included on a basis of BAT by fuel source and/or calculated on regional baselines Rate-based or indexed crediting : entities or projects emitting below a certain level (e.g. XtCO2/unit of primary metal) would generate credits Credits would flow through a bridge from the Clean Development Mechanism

30. © 2 0 06 APMGDiapositive 30 Questions What is sufficient participation (companies and countries)? Availability and reliability of emissions data (Russia/China?) Volume of credits, prices and buyers? How to recognize full life cycle benefits and promote recycling to help satisfy the growing demand for aluminium? Role of international associations Negotiation of baselines and other terms of agreement Role of independent international authorities (CDM model or a new multilateral agreement) Monitoring/Supervision of the system Enforcement issues Country-based approach Legal authority to ensure compliance

31. © 2 0 06 APMGDiapositive 31 EU Aluminium Sector Competitiveness While a global sector crediting agreement could promote environmental progress in non-annex (developing) countries, it will do nothing to promote the competitiveness of the EU aluminium industry CDM/JI trap – Even the existing CDM/JI mechanism militates against developing countries doing voluntarily what western industry already has done, as they expect to receive credits for adopting best practices. This would be exaggerated by a global sectoral crediting agreement; especially, if it was to include indirects EU industry will require mitigation of the CO2 cost pass through and to remain outside the EU ETS, post 2012, if it is to remain competitive

32. © 2 0 06 APMGDiapositive 32 Conclusions Alcan is well advanced in addressing GHG emissions on a voluntary basis Alcan’s technology can contribute further to GHG reduction Alcan’s R&D will reduce emissions and electro-intensity, further Alcan is encouraging the global industry, through the IAI approach, further to accelerate widespread adoption of best practices and best available technology Alcan is leading an industry consideration of how a sectoral crediting agreement could provide industry in developing countries further incentives to make environmental progress
