Primary aluminum production is one of the world’s most GHG-intensive industries, and also one where GHG accounting methods have become the most fully developed. GHG reporting for the primary aluminum sector has largely consolidated under the International Aluminium Institute’s (IAI) guidance, although Environment Canada (EC) guidance remains active and Chinese aluminum smelters will soon additionally be required to report their emissions under the China National Development and Reform Commission’s (China NDRC) guidelines, meant to support the development of the Chinese emissions trading system. The IAI method largely follows best GHG accounting practices, but aspects of it can be improved, and differences compared to other methods highlight open areas of contention.
