Nippon Steel Corp, based in Japan, runs heavy industry such as steel, cement, chemicals or aluminium. Climate TRACE attributes 10 high-emitting assets to it. Its largest tracked activities are steel making and electricity generation.

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.

Who profits

Hand-curated shareholder, revenue and investor context from primary public sources. This data is shown alongside the Climate Damage Score, but it is not used to compute it.

About this data. Institutional investors like BlackRock, Vanguard and State Street typically hold shares on behalf of clients; appearing in shareholder records does not mean they control or direct the company. State entities and individuals with majority stakes are different and labelled accordingly.

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.
Hard-to-Abate Process Emissions
Cement, steel and similar processes emit CO₂ from the chemical reaction itself, not only from burning fuel, which makes them hard to fully decarbonise.
Improving Trajectory
Attributed emissions are falling (~2%/yr): an improving trajectory, though absolute output remains large.
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 #15 mainly because its attributed assets emitted about 64.4 Mt CO₂e in 2024 (≈ 14M cars/yr).

The Climate Damage Score is driven by that absolute size on a log scale, with a -0.2-point flat adjustment.

What's known · what isn't

What’s known

  • Attributed emissions: 64.4 Mt CO₂e in 2024 (≈ 14M cars/yr).
  • Primary sector: Manufacturing; primary country: Japan.
  • Evidence: 10 assets; ~97% 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.
  • No PR claims, lobbying records, litigation history or policy-compliance data are included.
