1. Aluminium 1.56% growth in aluminium production in the last 10 years 2.40% of production in OECD, 2004 3.High trade - 75% of production traded 4.Highly concentrated - Top ten companies account for 54% of production 5.International Aluminium Institute - 99% of global capacity

2. Aluminium emissions 1.0.9% (estimated) of total anthropogenic GHG emissions 2.Two production routes – primary & secondary 3.Emissions sources (smelting stage, 80% of primary Aluminum emissions) –electricity:0 – 11.9 tonnes of CO 2 per tonne of aluminium –process PFC:1.8 –process CO 2 :2.2 –Other:0.3 4.Recent progress –recycling (secondary production) increasing –electricity use: 6% reduction 1990-2003 –PFCs emissions: 73% reduction 1990-2003

3. Primary and secondary aluminium, production and emissions intensity

4. Primary aluminium electricity use and emissions by region, 2003

5. 1.Adoption of Point Feeder Prebake Cells, current Best Available Technology (9 – 13% reduction) 2.Future –wetted drained cathodes (10-25% reduction) –inert anodes (additional 15% reduction) –carbothermic and kaolinite processes (2 – 6% reduction) Scope for Progress in Aluminium
