Emissions Reduction
Alcoa is regarded as a leader in the aluminium industry on addressing climate change.
In Australia, Alcoa is reducing greenhouse gas emissions through energy efficiency, productivity improvements and new technology. In 2003, we achieved our target of reducing global direct greenhouse gas emissions by 25% from a base year of 1990. Since 2003, we have further reduced global direct greenhouse gas emissions to 33% below 1990 levels.
Alcoa has made significant efficiency gains in both direct and total emissions per tonne of product (GHG intensity). Direct greenhouse gas emissions are those released directly, while indirect emissions are those that result from power stations that supply energy to be used in production or manufacturing, such as a smelter. Both direct and indirect emissions are added to calculate total greenhouse gas emissions.
Alcoa has reduced direct greenhouse emissions per tonne of production:
- aluminium smelters – by 61% from 1990 levels
- alumina refineries – by 11% from 1990 levels
- aluminium rolling operations – by 16% from 1990 levels
We have reduced total greenhouse gas intensity per tonne of production:
- aluminium smelters – by 16% from 1990 levels
- alumina refineries – by 12% from 1990 levels
- aluminium rolling operations – by 21% from 1990 levels
