Octopus Energy

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.

Octopus supplies 100% renewable electricity to its retail customers, operates demand-flexibility tariffs (Agile, Go, Intelligent Octopus) that shift load to high-renewables periods, and its Kraken platform now manages ~50 million accounts globally enabling grid flexibility at scale — but it continues to sell gas to millions of UK homes and does not yet have a credible plan to phase out gas retail.

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

Octopus Energy Group has not published SBTi-validated science-based targets as of mid-2025; the company makes strong marketing claims about renewables and net zero but lacks a publicly verifiable, independently validated emissions-reduction roadmap with Scope 1/2/3 baselines and milestones, and does not appear in the CDP public scores database as a disclosing entity.

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

Octopus has received recognition as a top UK employer (Glassdoor, Great Place to Work) and champions customer fairness, but as a private company its ESG disclosures are limited — no standalone sustainability report with independently audited operational emissions data has been published, and its rapid international expansion introduces supply-chain and labour governance complexity.

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

Octopus publishes marketing-grade claims about renewable sourcing and grid flexibility impact but does not produce a comprehensive, third-party verified sustainability or climate report; Kraken's claimed carbon-saving figures are proprietary and lack independent audit, reducing confidence in headline numbers.

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

Octopus has faced UK regulatory scrutiny (Ofgem complaints handling reviews) and some criticism over customer service during rapid growth; there are no major pollution, fossil-lobbying, or governance scandals on record, though its continued gas retailing is a modest integrity tension given its green branding.
