NuScale Power

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.

Nuclear SMR technology is genuinely carbon-free at the point of generation and displaces fossil baseload, giving NuScale a credible mitigation thesis, but the score is capped because no commercial plant has been built, the company's only flagship U.S. project was cancelled in 2023 due to cost escalation, and actual tonnes of CO₂ avoided remain zero to date.

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 quantified milestones have been found; NuScale joined the UN 24/7 Carbon-Free Energy Compact in 2022, and S&P Global Sustainable1 performed a limited Scope 1 and 2 GHG analysis per GHG Protocol, but these are far short of science-based targets with verified progress metrics.

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

As a pre-commercial engineering firm, NuScale's operational footprint is small (offices, labs, no operating reactors), limiting environmental harm, but the company publishes no standalone sustainability or ESG report, labour and social disclosures are minimal, and governance quality is materially undermined by multiple parallel securities-fraud class action lawsuits alleging misleading disclosures to investors.

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

Disclosure is limited to SEC mandatory filings (10-K, 10-Q, 8-K); there is no independently verified sustainability report, no CDP submission found, and the only ESG data point is a narrow S&P Global Sustainable1 Scope 1 and 2 GHG estimate — this is well below the standard expected for a company marketing itself as a climate solution.

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

NuScale faces multiple waves of securities-fraud class action lawsuits — first filed in late 2023 alleging materially misleading statements about customer contracts, then a new wave in 2026 over alleged misrepresentations about its ENTRA1 commercialisation partner, plus an SEC inquiry; the CFPP was cancelled after costs escalated from ~$55/MWh to ~$90/MWh, and an SEC investigation was disclosed in 2024 quarterly filings, all constituting serious and repeated governance concerns.
