#54 of 1649

CNOOC Ltd, based in Iraq, extracts, refines or transports oil, gas and coal. Climate TRACE attributes 4 high-emitting assets to it. Its largest tracked activities are oil & gas extraction and oil & gas transport.

Produces fossil fuelsOil, gas and coal are extracted, processed and moved at scale.
Methane can leakProduction and transport can release methane — a very potent short-term greenhouse gas.
Burned downstreamWhen the fuels are used elsewhere, they release large amounts of CO₂.

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.

HQ vs assets. Climate TRACE attributes emissions to assets by physical location, not corporate HQ. CNOOC Ltd is registered in China but its major emitting assets are in Iraq.

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.
Ownership Data Gaps
Only 50% of this entity's attributed emissions trace to a clearly identified owner. Incomplete ownership data limits accountability.
Methane Exposure
Oil and gas operations can release methane, a greenhouse gas far more potent than CO₂ over the short term. Leakage is often under-measured.
Improving Trajectory
Attributed emissions are falling (~7%/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 falling by about +6.6% per year. Attributed emissions, 2022–2024.

It ranks #54 mainly because its attributed assets emitted about 33.4 Mt CO₂e in 2024 (≈ 7.3M cars/yr).

The Climate Damage Score is driven by that absolute size on a log scale, with a -0.7-point improving adjustment.

What we know · what we don't

What we know

  • Attributed emissions: 33.4 Mt CO₂e in 2024 (≈ 7.3M cars/yr).
  • Primary sector: Fossil Fuels; primary country: Iraq.
  • Evidence: 4 assets; ~50% ownership-attribution coverage.
  • Source: Climate TRACE (CC BY 4.0).

What we don’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.
