Alcoa Corp, based in Australia, runs heavy industry such as steel, cement, chemicals or aluminium. Climate TRACE attributes 5 high-emitting assets to it. Its largest tracked activities are aluminium smelting.

High-temperature heatIndustrial furnaces burn large amounts of fuel for process heat.
Process emissionsSome reactions (e.g. making cement clinker) release CO₂ directly, on top of fuel use.
Traps heatThe combined CO₂ adds to global warming.

How it's allowed

Signals below are derived from emissions data and ownership coverage only, not from any legal or regulatory finding.

Permitted Emissions
These emissions appear to occur under existing permits and regulations. Operating legally is not the same as operating cleanly.
Low Measurement Confidence
Measurement confidence for this entity is low; figures are best-available estimates.
No Verified Enforcement or Lobbying Record
This dataset contains no verified enforcement actions, lobbying records, subsidies, or litigation for this entity. Absence of evidence here is not evidence of compliance or of any violation.

Climate Villains makes no claim that any entity has broken any law. These are data-derived signals, not allegations.

Attributed emissions are roughly stable year on year. Attributed emissions, 2022–2024.

It ranks #162 mainly because its attributed assets emitted about 15.3 Mt CO₂e in 2024 (≈ 3.3M cars/yr).

The Climate Damage Score is driven by that absolute size on a log scale, with no trend adjustment applied.

What's known · what isn't

What’s known

  • Attributed emissions: 15.3 Mt CO₂e in 2024 (≈ 3.3M cars/yr).
  • Primary sector: Manufacturing; primary country: Australia.
  • Evidence: 5 assets; ~75% ownership-attribution coverage.
  • Source: Climate TRACE (CC BY 4.0).

What isn’t

  • Exact ownership percentages: Climate TRACE lists owners but not stakes, so shared assets are split equally.
  • Indirect (supply-chain / financed / product-use) emissions are not included.
  • Some of this sector's emissions could not be attributed to any named owner.
  • No PR claims, lobbying records, litigation history or policy-compliance data are included.
