Aluminium 1.56% growth in aluminium production in the last 10 years 2.40% of production in OECD, 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

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 –PFCs emissions: 73% reduction

Primary and secondary aluminium, production and emissions intensity

Primary aluminium electricity use and emissions by region, 2003

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
