Climate Impact & Solution35%70

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 core process — converting waste CO2 and green hydrogen into drop-in SAF via a single exothermic step — is a genuine mitigation technology that could cut lifecycle aviation emissions significantly compared to fossil jet fuel, but remains at pilot scale with no publicly available, independently verified lifecycle GHG accounting (e.g., CORSIA or ASTM certification) and depends critically on truly green hydrogen supply that is not guaranteed.

Decarbonization & Targets20%18

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 validation, no CDP disclosure, and no publicly stated science-based net-zero targets have been found for OXCCU itself; the company is pre-commercial and has published no formal climate commitments, transition plan, or interim milestones beyond general language about advancing SAF commercialisation.

ESG & Operations15%38

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

As a small, early-stage spinout (~sub-50 employees) OXCCU has a minimal operational footprint, but it has published no ESG report, no supply-chain due diligence statement, no living wage or diversity disclosures, and its investor base includes Aramco Ventures and Eni Next — fossil fuel arms with documented poor climate alignment — which raises governance optics concerns even if they do not control the company.

Transparency & Verification15%30

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

OXCCU discloses milestone press releases and grant announcements but has published no lifecycle analysis (LCA), no independently audited emissions data, no annual report or sustainability report, and no ASTM/CORSIA fuel certification for its OXFUEL product; the ATI-funded non-CO2 effects study is a positive step but results are not yet public.

Integrity15%62

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

No direct controversies, litigation, pollution incidents, or governance scandals have been found for OXCCU; the primary integrity flag is reputational exposure from fossil-major investors Aramco Ventures and Eni Next whose climate credentials are widely contested, which does not implicate OXCCU directly but warrants investor scrutiny of board influence and future commercialisation partners.

Why it's on ClimateTicker

OXCCU is a pre-revenue deep-tech spinout from the University of Oxford developing a genuinely novel single-step CO2-to-SAF process that, if it scales with green hydrogen as feedstock, could meaningfully decarbonize aviation. The underlying science is credible and early demonstration hardware is real, but the company remains at pilot stage with no commercial production, no independently verified lifecycle emissions data, and a cap table that includes fossil-fuel majors (Aramco Ventures, Eni Next) whose core interests conflict with rapid decarbonization. Investors should weight the technology promise heavily against execution risk and the absence of formal ESG disclosures.

mitigationOXCCU plans to license or deploy its patented iron-catalyst Fischer-Tropsch reactor technology to produce synthetic SAF sold to airlines and fuel distributors; current revenue is grant- and equity-funded R&D with no commercial offtake contracts publicly confirmed.

Controversy & Greenwashing Watch

lowNo verified lifecycle emissions data published

OXCCU markets OXFUEL as low-carbon SAF but has not yet published independent LCA, CORSIA, or ASTM certification data to substantiate specific emissions reduction claims at pilot or commercial scale.oxccu.com

lowFossil-major investors in cap table

Aramco Ventures (arm of the world's largest corporate GHG emitter) and Eni Next are listed investors in OXCCU's Series A and Series B rounds, creating a potential conflict-of-interest optics issue even though OXCCU's technology is genuinely decarbonising.oxccu.com
