Seaway7

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.

Seaway7's entire commercial purpose is the physical installation of offshore wind infrastructure — it has installed over 800 WTG foundations and 2,500 km of inter-array cables enabling gigawatts of clean energy — but it is an enabling contractor, not a generator, and its own heavy vessel fleet burns substantial marine fuel (Subsea 7 group Scope 1 emissions hit ~748,000 tCO2e in 2024, up materially year-on-year), meaning the company's direct operational footprint partially offsets the climate value it enables.

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

Neither Seaway7 nor its parent Subsea 7 has SBTi-validated targets; Subsea 7 holds internal (unvalidated) pledges of 50% Scope 1+2 reduction by 2035 and net-zero Scope 1+2 by 2050, with CDP participation confirmed, but no third-party-validated near-term science-based targets exist and Scope 3 coverage is very thin (reported almost entirely as business travel), which is a significant gap for a heavy-marine-fleet operator.

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

Subsea 7's 2024 Annual Report (covering Seaway7) includes CSRD-compliant disclosures with a double-materiality assessment requiring over 15,000 work-hours, ESG performance assessed by multiple external ratings agencies, and active supply-chain anti-corruption compliance; however, Seaway7 publishes no standalone ESG report and its Scope 1 emissions (marine fuel) rose significantly in recent years as the heavy-transport fleet expanded, weakening the operational sustainability narrative.

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

Disclosure occurs primarily at Subsea 7 group level (CSRD-compliant from FY2024, CDP participant), with quantified Scope 1/2/3 GHG data published and externally assessed; Seaway7 itself has no standalone sustainability report, no SBTi validation, and no independently verified project-level carbon intensity metrics, limiting the depth of verifiable data specific to the wind-installation subsidiary.

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

No material controversies, regulatory enforcement actions, pollution incidents, labour violations, or greenwashing complaints against Seaway7 were found in public records; the company operates exclusively in offshore wind with reputable clients (Ørsted, ScottishPower Renewables, Equinor, SSE), though its parent Subsea 7 continues to serve the oil-and-gas sector, which some ESG frameworks flag as a governance concern for the group.
