Twelve

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 technology genuinely substitutes fossil feedstocks with captured CO2 and renewable electricity in aviation — one of the hardest-to-abate sectors — and AirPlant One is now commercially operational; however, current CO2 feedstock is primarily biogenic industrial waste (ethanol plants, pulp mills) rather than DAC, introducing lifecycle carbon-accounting uncertainty that constrains the full 90% emissions reduction claim.

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 commitment or validated science-based targets were found; no CDP disclosure is publicly listed; the company's stated mission to 'eliminate global emissions' and build a 'fossil-free future' constitutes aspirational positioning rather than a credible, time-bound, third-party-verified net-zero plan with measurable milestones.

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

Twelve's operational footprint at AirPlant One uses hydropower-sourced renewable electricity, which is structurally sound; the company is a private VC-backed startup with no published sustainability report, no material labour controversies, and governance led by PhD-founder scientists — but the absence of any ESG reporting framework, board diversity disclosure, or supply chain audits limits scoring.

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

Twelve's lifecycle emissions figure of 'up to 90% lower' is self-reported with no publicly available independent LCA audit or third-party verification; SAF credits are tracked through IATA registries which provide some chain-of-custody traceability, but no GHG inventory, scope breakdown, or sustainability report is publicly disclosed for the company's own operations.

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

No material controversies, litigation, pollution incidents, fossil-fuel lobbying, or governance scandals were identified in public records; the company has US Air Force, Microsoft Climate Innovation Fund, and TPG Rise Climate as partners and backers, which implies baseline due-diligence scrutiny, and no greenwashing complaints have been filed against Twelve specifically.
