Climate Impact & Solution35%12
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.
SLB's core business — oilfield services across drilling, production, and reservoir characterization — directly enables fossil fuel extraction at scale; its 'Transition Technologies' portfolio generated over $1B revenue in 2023 but that figure is dwarfed by $33B in total revenue, and LobbyMap finds the company 'appears opposed to an energy transition from oil and gas' and emphasizes a long-term need to maintain fossil fuels contrary to IPCC guidance.
Decarbonization & Targets20%32
Credible, science-based targets (SBTi), a real net-zero plan with progress to date, and CDP disclosure — not just a dated press release.
SLB has a self-declared 2050 net-zero ambition covering all three scopes (claimed as a first in energy services in 2021) and reports a 40% Scope 1 & 2 reduction vs. 2019 baseline, but as of November 2025 no SBTi-validated targets appear on public registries, and no independently verified net-zero target has been confirmed by third parties.
ESG & Operations15%45
Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.
SLB holds an MSCI AA ESG rating and CDP A- for Climate (2025), reports 30% women in executive leadership, and ties 10% of executive short-term incentive pay to quantitative emissions and gender goals, but faces ongoing harassment lawsuits, labor disputes, and class-action litigation that temper its social performance.
Transparency & Verification15%48
Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.
SLB aligns its sustainability reporting with TCFD, SASB, GRI, and UN SDGs and discloses Scope 1, 2, and 3 metrics, but the absence of SBTi-validated targets, limited third-party verification of customer 'avoided emissions' claims (~950,000 tCO2e in 2024), and only a partial industry-association disclosure undercut the credibility of its disclosures.
Integrity15%28
Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.
SLB pled guilty and paid $232.7 million for violating U.S. sanctions by facilitating trade with Iran and Sudan; as of 2025 it remains active in Russia despite U.S. sanctions (Ukraine added it to its war-sponsors list), is a member of obstructive climate lobbying groups including the American Petroleum Institute, and faces multiple ongoing labor and harassment class-action suits.

Why it's on ClimateTicker
SLB is the world's largest oilfield services company, deriving the overwhelming majority of its revenue from enabling fossil fuel extraction — its core business is structurally incompatible with rapid decarbonization. While the company has made measurable operational emissions cuts and is investing in carbon capture and 'New Energy,' these efforts remain small relative to the scale of upstream oil and gas it continues to expand. Investors should treat SLB as a fossil-fuel enabler pivoting at the margins, not a genuine climate solution.
