Latest Carbon Performance data for steel and aluminium companies now available

The latest Carbon Performance data for the world’s largest steel and aluminium companies are now available. This update covers 40 steel and 28 aluminium companies¹. Together, these companies represent a combined market capitalisation of over $741 billion as of July 2025².

Steel and aluminium are among the most carbon-intensive industries globally. According to the International Energy Agency (IEA), the steel and aluminium industries released 2.8 Gt and 0.3 Gt of CO2, respectively, in 2023 – together representing 8.1% of global CO2 emissions from energy combustion and industrial processes. The TPI Global Climate Transition Centre (TPI Centre) methodology assesses historical and projected greenhouse gas (GHG) emissions, comparing them against sector-specific benchmarks to evaluate their alignment with the goals of the Paris Agreement.

The Transition Pathway Initiative (TPI) is supported by over 150 asset owners and asset managers globally. Its research and data are produced by the TPI Centre at the London School of Economics and Political Science (LSE), the academic partner of the initiative.

¹ These assessments cover TPI companies outside the Climate Action 100+ (CA100+ ) universe, allowing earlier publication of results. This ensures investors have up-to-date data well ahead of the typical Q3 publication of CA100+ company assessments.

² Market capitalisation coverage is calculated for the companies for which this sector represents their primary activity. The calculation can change due to fluctuating corporate valuations, the size of the company universe assessed, or due to company sectoral reclassifications.
