Who profits

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

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.
Fossil-Fuel Power Generation
Attributed emissions include fossil-fuel power generation, which is among the most carbon-intensive ways to produce electricity.
Improving Trajectory
Attributed emissions are falling (~6%/yr) — an improving trajectory, though absolute output remains large.
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 falling by about +5.8% per year. Attributed emissions, 2022–2024.

It ranks #68 mainly because its attributed assets emitted about 29 Mt CO₂e in 2024 (≈ 6.3M cars/yr).

The Climate Damage Score is driven by that absolute size on a log scale, with a -0.6-point improving adjustment.
