Climate change is a complex global issue that has significant implications for governments, industry and society alike. For Alcan, addressing the economic, social and environmental dimensions of climate change is directly related to the Company's global competitiveness and preservation of its long-term licence to operate.

Key Challenges and Opportunities:
•   Continue process-related improvements (including energy efficiency) to reduce greenhouse gas (GHG) emissions from operations.
•   Continue to develop more efficient products, the use and disposal of which contributes to lower GHG emissions.
•   Continue efforts with other companies, governments and third parties to ensure that pragmatic and cost-effective solutions are found to reduce GHG emissions.

As an aluminum producer, Alcan's GHG emissions are predominantly (about 75%) from the smelting activities in the Primary Metal business group. To produce molten aluminum, electricity is used to power an electrolytic reaction whereby oxygen combines with carbon from a carbon anode, resulting in carbon dioxide (CO2) being emitted during the process. If fossil fuels are used to generate the electricity consumed, additional CO2 emissions result. Furthermore, perfluorocarbons (PFCs) are produced intermittently in the smelting process during what is known as the "anode effect", essentially related to the raw material feeding philosophy, which as a result has been completely changed. Until recently, anode effects were considered a necessary part of the raw material feeding process. One kilogram of CF4 (PFC) has about the same greenhouse gas effect as 6,500 kilograms of CO2, illustrating how PFCs are extremely potent greenhouse gases.

In absolute terms, Alcan's direct emissions of carbon dioxide equivalent (CO2e) from fuel consumption and operation processes in 2004 were 23.7 million tonnes. When combined with indirect emissions from purchased electricity and emissions from the transportation of products, Alcan's total CO2e emissions in 2004 were 41.2 million tonnes, reflecting the addition of all Pechiney sites.

Direct & process
Indirect
Transportation

Direct emissions are from fuel consumption and operating processes. Other emissions include estimates related to the production of purchased electricity and transportation of Alcan-owned raw materials and products.

The increase in absolute emissions in 2004 is due to acquisitions. In 2004, this reflects primarily the integration of all Pechiney sites. The direct emissions increased by approximately 60%, whereas the indirect emissions increased by approximately 300%. This is due to the fact that the indirect emissions coming from energy sources of the acquired sites are largely carbon based.

87% of Alcan's GHG emissions are related to operations located in Annex B countries of the Kyoto protocol.

North America and Europe account for about 30% of Alcan’s total GHG emissions. More than 20% of GHG emissions are in Australia, which now include smelting and alumina refining capacities added through the Pechiney acquisition. Asia accounted for 7% in 2004 due to new engagement in a joint-venture smelting operation in China.




Overall, businesses have an important role to play in managing GHG emissions. Alcan is driving its operations to benchmark performance in terms of reducing its own greenhouse gas emissions, developing products that reduce GHG emissions in their use and disposal, as well as engaging in effective dialogue with key stakeholders. Governments, investors, consumers and NGOs are all monitoring industry efforts to reduce CO2e emissions, as well as how these businesses publicly report emissions data. Alcan knows that the future acceptability of its operations and products will be judged, in significant measure, by its ability to reduce the intensity of its GHG emissions. In this regard, its ambition is to become climate neutral by no later than 2020 through the full life cycle assessment of its products.
