A Strategic Approach to Climate Change
3
Alcan’s proactive and progressive approach to the reduction of GHG
emissions has been driven by a “win-win” philosophy – driven by a
sustainability approach.
Alcan’s strategy includes:
Continued reduction in process-related GHG emissions
Development of new technologies
Promoting the use of aluminium as a contributor to reduce GHG
emissions through product lifecycle
Engagement in the development of a global policy framework

Alcan recognized early the need to tackle
GHG emissions
Already in 2000 Alcan launched its first
TARGET program, a company-wide
greenhouse gas management program
4
TARGET includes reduction objectives
Smelter emissions - Worldwide comparison 1990 to 2006:
© 2007 ALCAN INC
Total smelter emissions (direct + indirect) reduced by 25%
Production increased by 35%
Intensity decreased by 45%
2006-2010 objective to further reduce direct GHG intensity by
10%
Continuous improvements in energy efficiency
in Alcan’s smelters to reduce GHG from
electricity production

Aluminium and Climate Change Opportunities
Recyclability
8
Opportunity: high recycling rates (90%) decrease substantially
product footprint, better than competitive materials
Light weight
Opportunity: replacing heavier materials in transport
applications
Electrical properties
Opportunity: Increase size of cable to improve energy
efficiency
Barrier function
Opportunity: More packaging of food to decrease food spoilage
Brightness, reflectivity
Opportunity: new product for renewable energy generation
