Climate Impact & Solution35%18
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.
Cadent's core business is delivering fossil natural gas; methane emissions represent 90–95% of its business carbon footprint, and its hydrogen and biomethane initiatives remain pre-commercial or small-scale, meaning the network today is a net emitter with only marginal near-term abatement.
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.
Cadent has Carbon Trust Route to Net Zero 'Taking Action' certification and self-assessed science-based Scope 1/2 targets developed with the Carbon Trust, but as of 2024 these remain unvalidated by SBTi because no approved oil-and-gas methodology yet exists, leaving the targets credible in intent but unverified in standard; no validated Scope 3 target exists.
ESG & Operations15%52
Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.
Cadent scores well on operational ESG metrics — GRESB Sector Leader (100/100), BREEAM-rated HQ, EV fleet conversion underway, strong labour/DEI programmes, and biodiversity commitments — but these are offset by the structural emissions of the gas network itself and repeated Ofgem penalties for operational shortfalls.
Transparency & Verification15%48
Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.
Cadent publishes annual sustainability and environmental reports with quantified metrics and has third-party Carbon Trust certification, but SBTi validation is pending, CDP disclosure status is not publicly confirmed, and Scope 3 emissions reporting remains incomplete; transparency is above sector average but falls short of best-in-class.
Integrity15%42
Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.
Cadent has accumulated material regulatory penalties including the UK's largest-ever gas network fine (£44m, 2019), a £1.5m Ofgem penalty for late emergency attendance (2025), repayment of £800,000+ in public hydrogen-trial funding following a failed and publicly-contested hydrogen village project, and accusations of 'manipulation, misinformation and deceit' in community engagement.

Why it's on ClimateTicker
Cadent Gas is the UK's largest gas distribution network and derives its entire revenue from transporting fossil gas — a fundamentally high-emission core business. It pursues operational decarbonisation through methane leakage reduction, fleet electrification, and hydrogen infrastructure investment, but the company's very existence perpetuates natural-gas dependency; genuine climate benefit is marginal and contingent on an unproven large-scale hydrogen transition. Investors should treat green credentials as partial and provisional rather than transformative.
