Fervo Energy

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.

Geothermal EGS is a near-zero-emission, firm-power source that directly replaces fossil baseload; Cape Station's 500 MW pipeline (first 100 MW late 2026) represents verified, grid-connected clean generation — the highest-quality form of climate impact — though no lifecycle emissions data has been independently published.

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 plan with quantified milestones were found; Fervo's climate commitments remain at the level of mission statements and qualitative marketing language, which is common for a growth-stage company but scores poorly on third-party target rigor.

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

Fervo publicly documents a DOE-aligned induced seismicity mitigation protocol and exclusively uses degraded (non-fresh) water across all operations, which are meaningful environmental positives; however, no formal ESG or sustainability report with independently assured operational metrics (Scope 1/2/3 GHG inventory, labor data, safety statistics) has been published, limiting scoring to partial credit.

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

Fervo's SEC S-1 and 10-Q filings (post-May 2026 IPO) provide some financial and project-status disclosure, and the company publishes technical blog posts and white papers; but there is no third-party verified sustainability report, no CDP response, and quantified environmental KPIs (emissions intensity, water volumes, seismic event counts) are not consolidated in an auditable public document.

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

The only material legal event found was a patent dispute with Ormat Technologies filed January 2024 and settled February 2025 with no admission of wrongdoing; no environmental violations, pollution events, fossil-fuel lobbying, conflict-zone involvement, or governance scandals were identified.
