About this report

Boundary

Welcome to Alumina Limited’s 2015 Sustainability Update.  This report is designed to provide the reader with a description of the economic, social and environmental performance of Alumina Limited and its investment in AWAC (Alcoa World Alumina and Chemicals), our global joint venture with Alcoa.  

This update supports Alumina Limited’s commitment to report on non-financial performance as outlined in our sustainability policy and our commitment to high-levels of transparent disclosure. It is specifically designed for the investment community including institutional and retail shareholders who are interested in the long-term sustainability of Alumina Limited, though it may also be of interest to representatives from government and local communities where AWAC operates. 

While the report covers Alumina Limited’s results, its emphasis remains on AWAC operations where the greatest sustainability impact lies. Therefore the aim of the report is to give easy access to consolidated information about AWAC’s sustainability performance and lead to greater understanding about the quality and value of these assets.

Guide to entity references

Three main entities are mentioned throughout this sustainability report - Alumina Limited, AWAC and Alcoa Inc. To aid the reader’s understanding, we have described each entity’s role below as well as the rationale for when these entities are referred to in the report.

Alumina Limited is the non-operating partner in the AWAC joint venture of which it owns 40 per cent. As this is an Alumina Limited’s sustainability report to stakeholders, the organisation is sometimes referred to in the first person (we, ours). Other references to Alumina Limited are made with respect to:

  • joint venture partner undertakings
  • the governance procedures and frameworks that guide the strategic direction of Alumina Limited, including policies, values and codes
  • activities that it takes to pursue long-term value for shareholders.

AWAC (Alcoa World Alumina and Chemicals) is an the joint venture enterprise owned jointly by Alumina Limited (40 per cent) and Alcoa Inc. (60 per cent). This enterprise includes global bauxite, alumina and aluminium assets. AWAC references are used to describe:

  • the physical assets, interests and operations that form the basis of the joint venture (e.g. AWAC’s Huntly bauxite mine)
  • the outcomes and performance levels from the operation of these assets (e.g. AWAC’s production levels, AWAC’s revenue, emissions, resource usage, market position)
  • the governance procedures and frameworks that determine the strategic directions, investments and acquisitions of the enterprise (e.g. the AWAC Strategic Council).

Legally the joint venture is conceived as an unincorporated joint venture based on a Formation Agreement between Alumina Limited and Alcoa Inc. However, Alumina Limited does hold direct ownership in some operating entities of the AWAC enterprise.

AWAC produces and sells alumina, bauxite and aluminium into the global market. AWAC's principal business is the production of alumina, the main raw material used in the manufacture of aluminium. AWAC's products are sold around the world to Alcoa and third parties.

Alcoa Inc. (Alcoa) owns 60 per cent of the AWAC joint venture and is the operating manager of the enterprise. Based on this role, references to Alcoa are used in relation to joint venture partner undertakings as well as actual on-site management of AWAC facilities, including:

  • the management team and employees who carry out day-to-day activities
  • policies, procedures and processes that are applied to everyday activities at AWAC operations.

 

Measurement techniques

Alumina Limited as a non-operating joint venture partner relies on the data measurement techniques and bases of calculations employed by AWAC's manager/operator, Alcoa. Alcoa uses a variety of internal standards and data collection systems, as well as a rigorous internal and external audit process. Alcoa conform to external data reporting standards, such as the Carbon Disclosure Project, and comply with government statutes like the US Sarbanes-Oxley Act.

External assurance

Alcoa as manager/operator of the AWAC enterprise, are responsible for the data management, data collection and calculation of sustainability metrics such as CO2 emissions. Alcoa engaged First Environment Inc. to provide limited assurance on their consolidated Scope 1 and Scope 2 greenhouse gas (CO2, CH4, N2O, FPC’s and SF6) emissions data (that includes AWAC operations) un the ISO 14064, Part 3: Specification with guidance for the validation and verification of greenhouse gas assertions.  Refer to copies of the relevant Verification Statements 

In 2015, Alumina Limited submitted an Investor CDP (Climate Change) report and also a CDP Water Information report. It is Alcoa's intent to provide future water data assurance.
