Climate Impact & Solution35%78

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 Deep Green tidal kite directly displaces oil-fired generation on the Faroe Islands grid and, at scale (200 MW planned), could supply 40% of Faroese electricity demand while enabling a 100%-renewable target by 2030 — a genuine, measurable mitigation impact, though currently only ~1.4 MW is installed and commercially producing.

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 commitment, no CDP disclosure, and no publicly available independently verified GHG emissions inventory were found; climate ambition is expressed only through product mission statements and the Faroe Islands 100%-renewable-by-2030 host-nation goal, not through any company-level science-based target.

ESG & Operations15%42

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

Environmental monitoring (hydrophone, bird, and marine mammal studies) is conducted at deployment sites in collaboration with universities and regulators, and a DNV third-party technology review has been completed; however, no standalone ESG or sustainability report, no labor/supply-chain disclosure, and no Scope 1–3 GHG inventory are publicly available in English, limiting ESG score.

Transparency & Verification15%35

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

Financial reporting is published on Nasdaq First North but the annual report is in Swedish only, no English-language sustainability report or third-party-verified emissions data has been found, and operational performance data (energy produced, capacity factors) is released selectively via press releases rather than structured, auditable disclosures.

Integrity15%80

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

No material controversies, pollution incidents, fossil lobbying, litigation, or governance scandals were identified; the Wales office closure and prior supply-chain pivot away from Holyhead Deep represent execution and commercial risk but not integrity failures, and the company has maintained consistent public messaging.

Why it's on ClimateTicker

Minesto develops genuinely zero-emission tidal kite technology that displaces fossil-fuel generation on island grids — notably the Faroe Islands, which historically sourced ~57% of power from oil. The core technology is credible and independently reviewed by DNV, with grid-connected megawatt-scale output now demonstrated. However, the company remains pre-revenue, pre-profitability, and early-commercial, so its climate impact is currently modest in absolute terms and its own operational sustainability disclosures (SBTi, CDP, verified GHG inventory) are absent.

mitigationMinesto sells tidal electricity under power purchase agreements (e.g., with Faroese utility SEV) and pursues project development revenues; it is currently funded primarily through equity raises, EU grants (>€45M), and national agency grants while scaling toward commercial array build-out.

Controversy & Greenwashing Watch

lowWeak rights issue uptake signals investor confidence risk

In October 2025, only ~41% of Minesto's rights issue was subscribed by shareholders, requiring guarantors to cover ~24% of the raise, indicating limited market confidence in near-term commercialization.prnewswire.com

lowWales operations withdrawal and office closure

Minesto deprioritized its Holyhead Deep, Wales project in March 2022 citing supply chain issues, and closed its Welsh manufacturing office in July 2025, raising questions about execution reliability and stranded local investment.en.wikipedia.org
