Supply Chain Management

Alcoa use their Global Supplier Sustainability Program to assess and help improve sustainability of AWAC's key suppliers that present the biggest sustainability risk to the business. These include companies that contribute the most to AWAC's carbon footprint, possess preferred status, are sole sources of supply, are located in emerging or high-risk countries, or provide regulated commodities.

 The program consists of four components:

  • Communicate expectations: Clearly define our sustainability expectations and communicate them through discussions and Alcoa's Supplier Standards.
  • Assess supplier: formally assess the performance of key suppliers to evaluate the maturity of their sustainability programs and determine where improvements are needed. 
  • Develop and educate: For suppliers that fall into the emerging and lagging categories, provide education and tools to develop and improve their programs. Also require action plans and demonstrated improvements in the development of their sustainability programs.
  • Monitor: reassess suppliers in the emerging and lagging categories annually.  Those that do not demonstrate annual improvements face the risk of losing AWAC's business.
