Climate change

Key elements

• 1.5°C GHG emission pathways for all certifying Entities, using ASI GHG Pathways Method and Calculation Tool. The GHG Pathways Decision Tree assists with the choice of base year and evidence requirements. Both tools are available on the Document Centre under ‘Tools’.
• GHG emissions reduction plans for all certifying Entities
• Direct and indirect emissions included:
  • Primary production: cradle-to-gate pathways (scopes 1,2 & upstream 3)
  • Downstream procurement pathways (scope 3 category 1).
  • Casthouse and semi-fabrication process pathways (scopes 1 & 2)
• Additional smelter emissions intensity thresholds are designed to exclude new coal-fired production from certification but to allow existing coal-intensive producers to certify by reducing their emissions along aggressive emissions reduction pathways
• A cradle to gate or ‘mine to metal’ approach to smelter thresholds includes emissions from bauxite mining, alumina refining, transport and carbon footprints of other inputs to the process (scope 1, scope 2, scope 3 categories 1,3 and 4)
• Public disclosures of GHG data as a critical component of transparency, with independent verification before publication
• The wide scope of the ASI Performance Standard aims to ensure that emissions reduction does not come at the expense of other critical environmental, social and governance (ESG) risks
• The ASI Chain of Custody Standard provides a mechanism for cradle to gate emissions data to be connected to metal flow through optional carbon footprint disclosure, no matter where in the value chain the Entity operates
