Drive sector-wide climate change mitigation and adaptation within a below 1.5°C scenario

ASI Certification

ASI’s goal is to reduce the aluminium sector’s emissions in line with climate science.

ASI Performance Standard V3 (2022) mandates all Entities to establish targets and plans to reduce direct and indirect emissions in line with 1.5°C aligned pathways.

It also demands annual disclosure of independently verified emissions data.

The Standard defines quantitative threshold emissions intensity performance for aluminium smelters only.

Key elements

  • 1.5°C pathways for all certifying Entities
  • Direct and indirect emissions included: technology or energy use pathways for those with high scope 1 and scope 2 contributions, and/or material procurement/sales strategies for those with high scope 3.
  • Smelter 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 1.5°C aligned pathways, meaning reductions of the order of up to 50% by 2030, but over 95% by 2050
  • 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

Beyond certification

  • Partnering with CRU Group on data alignment for their Emissions Analysis Tool, to support access to GHG data at the asset level, filter greenhouse gas emissions benchmarking curves by ASI Certification status, and understand Certification along specific supply chains to support chain of custody
  • Partnering with International Aluminium Institute on projects to develop Entity-level 1.5°C pathway methodologies and an asset-based tool for assessing and managing site-level climate-related health and safety risks and
  • Active in Mission Possible Partnership, to encourage the use of common methods and standards and to use ASI’s Standards to drive change along a 1.5°C pathway
  • Active in the Aluminum Climate-Aligned Finance Working Group for the Center for Climate Aligned Finance to develop a robust methodology, net-zero roadmap, data access and scale to support lenders and clients on net-zero targets for aluminium portfolios

“Merit Aluminum Inc. is committed to responsible environmental practices that protect our planet. Global warming is the existential threat to humanity. It is everyone’s responsibility to reduce their carbon footprint in their daily lives, and even more so for those that are business owners, no matter what size the business. We cannot rely on governmental intervention as our only means to deal with this threat. As shepherds of our planet, we must take whatever steps necessary, within each of our means, to create a carbon neutral world. To accomplish that, we all have to work together providing the leadership that others will and must follow. Failure to do so, the consequences are unimaginable.”

— Mike Rapport, President, Merit Aluminum Inc.



“We have an aluminium problem; Unsustainable production, power consumption and carbon emissions are creating irreversible environmental consequences that affect everyone. They can’t be ignored, and we need to work collaboratively to address them.

For us at Romco, subscribing to the Aluminium Stewardship Initiative (ASI) is an exciting step in that direction — joining others in the industry that are taking responsibility for making our world a cleaner, greener, more liveable place.”

— Raymond Onovwigun, Romco Group CEO
