Climate Impact & Solution35%72

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.

Core technology directly removes historical atmospheric CO₂ and is designed to run on 100% renewable electricity, giving it a strong theoretical climate impact — but actual removal volumes across all three deployed systems total only ~750 tCO₂/yr at best, and no independent lifecycle analysis or verified removal certificates have been publicly disclosed, leaving the real net-removal figure unconfirmed.

Decarbonization & Targets20%28

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, and no published net-zero roadmap with interim milestones were found; the company's public commitments are limited to aspirational product-roadmap language ('megatonne capacity by end of decade') without independently verified science-based emissions reduction targets for its own operational footprint.

ESG & Operations15%52

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

The company is a ~44-person London-based startup with climate-aligned investors (Breakthrough Energy Ventures, World Fund, 2150) and stated intention to use only renewable energy in operations; no labour controversies or governance scandals were found, but no formal ESG reporting, gender pay gap disclosure, or supplier code of conduct is publicly available.

Transparency & Verification15%35

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

Public disclosures are primarily marketing materials, investor announcements, and blog posts; no audited sustainability report, no CDP response, no independently verified lifecycle analysis of energy consumption or net CO₂ removal per tonne, and no third-party-validated removal certificates have been publicly identified — the claimed 62.5% energy savings versus incumbents appears only in investor materials without citing peer-reviewed or independently verified data.

Integrity15%88

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

No controversies, litigation, pollution incidents, fossil-fuel lobbying, or governance scandals were identified; the company explicitly acknowledges the risk of DAC being misused to enable continued fossil emissions and states it is 'being extremely careful about the end use of its technology'.

Why it's on ClimateTicker

Mission Zero Technologies is a genuine carbon removal company building electrochemical direct air capture systems that physically extract CO₂ from the atmosphere — the core business is unambiguously mitigation. However, as an early-stage startup with three small pilot installations (each targeting ~250 tCO₂/yr), actual verified removal volumes are negligible today, and the credibility of the 'megatonne by end of decade' roadmap rests entirely on unverified technology-scale claims. The impact thesis is sound in principle but investors should treat all forward-looking volume and cost figures as unaudited startup projections.

mitigationSells and deploys modular electrochemical DAC hardware to carbon removal project developers (e.g. Deep Sky) and CO₂ utilisation partners (sustainable aviation fuel, carbon-negative building materials, mineralisation), with potential recurring service/maintenance revenue; the company does not itself sell carbon credits.

Controversy & Greenwashing Watch

lowScale gap between marketing and deployed reality

The company markets a 'megatonne by end of decade' ambition while all current operational systems combined target only ~750 tCO₂/yr — a gap of roughly three orders of magnitude with no published credible bridging plan.climatetechdigital.com

lowUnverified efficiency claims

The headline claim of '62.5% energy savings vs competitors' appears only in investor-facing materials without citation to peer-reviewed data or independent third-party benchmarking, creating a minor but material transparency gap.worldfund.vc
