The IAI, WBCSD and WRI have released updated tools and guidance documents for calculating greenhouse gas emissions from primary aluminum production.

The International Aluminium Institute (IAI), the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI), working together under the Greenhouse Gas Protocol (GHG), have released updated tools and guidance documents for calculating greenhouse gas emissions from primary aluminum production.

The tools feature additional worksheets that provide increased flexibility for producers collecting activity data according to several different national reporting requirements. They also have been expanded to cover the entire range of primary aluminum production processes that produce greenhouse gases.

IAI and its member companies, with the support of EPA, began developing the Aluminium Sector GHG Protocol in early 2002. It is based on protocols previously developed by WRI and the WBCSD, and was peer reviewed and endorsed as conforming to their model.

The GHG Protocol is geared towards a range of users, from environment, health and safety managers to project developers, and from small offices to large companies. A primer on calculating emissions is available at www.safeclimate.net. See www.world-aluminium.org/environment/climate/ghg_protocol.pdf and www.ghgprotocol.org.
