Climate Impact & Solution35%82
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.
Tidal stream turbines produce zero-emission, predictable electricity; Nova has operated the world's first offshore tidal array since 2016 and regulators have independently assessed its turbines as having no negative impact on the marine environment, directly avoiding fossil generation at small but proven scale.
Decarbonization & Targets20%22
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 milestones were found in any public source; sustainability language on Nova's website is aspirational and unquantified, scoring this category very low.
ESG & Operations15%48
Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.
Nova engages local supply chains (approx. 60% Scottish content in SEASTAR turbines), grew from 35 to ~70 employees, and partners with environmental consultants (Nature Positive) on SEASTAR, but no independently verified ESG report, labour policy disclosure, or board governance documentation is publicly available.
Transparency & Verification15%32
Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.
Nova publishes operational milestones and project announcements but has no publicly available audited sustainability report, GHG emissions inventory, or independent third-party verified ESG data; the claim of '40% cost reduction' is company-stated, not externally audited.
Integrity15%78
Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.
No material controversies, litigation, pollution incidents, fossil-fuel lobbying, conflict-zone involvement, or governance scandals were identified in public sources; the company receives endorsements from the Scottish National Investment Bank and Scottish Government and has EU Horizon Europe project funding.
Why it's on ClimateTicker
Nova Innovation is a genuine pioneer in tidal stream energy — a zero-emission, highly predictable renewable source — with a decade of real operational data from the world's first offshore tidal array in Shetland. The core business model directly displaces fossil generation and the technology has cleared independent environmental regulators. However, the company remains pre-scale, its own operational footprint disclosures are thin, and there is no SBTi, CDP, or audited sustainability reporting found in public sources, so claims of sustainability leadership outrun the verifiable evidence.

Controversy & Greenwashing Watch
Despite strong green marketing language, Nova publishes no independently verified GHG inventory, sustainability report, SBTi commitment, or CDP response, creating a gap between claims and verifiable evidence.novainnovation.com
Three of Nova's six Shetland turbines were removed in 2023 at the conclusion of the EnFAIT project, reducing the operational array from a headline 0.6 MW back to just 0.3 MW, undermining the 'world's largest tidal array' marketing claim.en.wikipedia.org
