Zero Petroleum

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.

The technology — capturing atmospheric CO₂ and using green hydrogen to synthesise drop-in fuels — is theoretically carbon-neutral and addresses genuinely hard-to-abate sectors, but at current production volumes (engineering-scale Plant Zero.1, pre-commercial) actual emissions avoided are negligible, and no independent LCA has been published to verify the full lifecycle carbon balance including plant construction and electrolysis energy sourcing.

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

No SBTi-validated targets, no CDP disclosure, no published net-zero roadmap with milestones or progress reporting were found; the company's only public climate commitment is the vague self-description of its fuel as 'carbon-neutral', which is unverified by any independent body.

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

As a small startup (~founder-led, pre-revenue at scale), Zero has no published ESG or sustainability report, no disclosed labour practices or supply-chain standards, and no formal governance disclosures beyond UK Companies House filings; Innovate UK and RAF partnerships suggest basic institutional governance compliance, but there is no evidence of structured ESG management.

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

Zero's website makes bold 'carbon-neutral' and '100% drop-in' claims backed only by self-description; Intertek has a partnership for certification testing but no certified LCA or verified emissions data has been publicly released, and the company publishes no annual report, sustainability report, or quantified emissions data.

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

No material controversies, litigation, pollution incidents, fossil-fuel lobbying affiliations, conflict-zone involvement, or governance scandals were found; the company's public partnerships (RAF, Innovate UK, Intertek, UK SAF Clearing House) are credible institutional actors, and co-founder Nilay Shah holds an OBE for services to UK decarbonisation.
