Halliburton Company

Does the core business genuinely avoid or reduce emissions, or build climate resilience? Share of revenue that is actually 'green'. Fossil-dependent models score low.

Halliburton's core business is maximising hydrocarbon extraction for E&P customers; peripheral offerings in geothermal and CCUS are nascent and represent a tiny fraction of revenue, while its own filings explicitly forecast growing oil and gas demand as a business driver.

Credible, science-based targets (SBTi), a real net-zero plan with progress to date, and CDP disclosure — not just a dated press release.

Halliburton submitted an SBTi commitment letter in 2020 promising validated targets by 2022, but as of mid-2026 no SBTi-validated targets appear on the SBTi dashboard; its internal 40% Scope 1+2 intensity-reduction-by-2035 target is unvalidated, covers only operational emissions, and does not address Scope 3 from the hydrocarbons its services produce.

Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.

Halliburton publishes annual sustainability reports and has a CPA-Zicklin Trendsetter rating (93/100) for political-spending disclosure, but absolute Scope 1+2 emissions were ~4.67 Mt CO2e in 2024 and rose 15% year-over-year in 2022-2023 due to activity growth, undermining emissions-intensity progress; labour and safety data are reported but subject to self-reporting bias.

Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.

Halliburton discloses Scope 1, 2, and limited Scope 3 data in its annual sustainability report and SEC filings, and claims third-party assurance, but there is no CDP public response found, SBTi validation was promised but not completed, and Scope 3 from customer end-use of produced hydrocarbons is excluded — the single largest emissions category.

Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.

Halliburton carries significant controversy: $1.1 billion Deepwater Horizon settlement, a 2015 court finding of illegal whistleblower retaliation, EPA transparency refusals over fracking chemicals, an ongoing asbestos trust with over $1.98 billion paid to date, groundwater contamination settlements in Oklahoma, and documented lobbying against oil and gas permit phase-out legislation.
