GHG measurement and inventory for aluminum production

Abstract

The primary aluminum industry has achieved good progress over the past decade in reducing GHG emissions associated with metal production. The reductions have been tracked through well documented protocols for the measurement of GHGs associated with production processes as well as established inventory accounting methodologies, vetted by stakeholders from within and outside the industry. These protocols and inventory methodologies are currently in the process of being updated to reflect new findings and changes in the industry over the past decade, to further enhance the accuracy and robustness of GHG accounting for the aluminum industry. This paper discusses the revisions being considered and the factors driving the changes.
