Mixergy

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 core product demonstrably cuts household hot water energy use and enables renewable energy absorption, backed by third-party validation from the Energy Savings Trust (up to 21% gas reduction), Energy Systems Catapult (12% real-world energy reduction in Cornwall trial), and a verified 172-tonne CO₂ reduction across 1,000+ Birmingham City Council units over two years — genuine mitigation with quantified field data, though absolute fleet-wide CO₂ avoided is not 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 transition plan with milestones or Scope 1–3 inventory were found; the company references UK net-zero alignment in marketing copy but has no independently verified corporate climate commitment of its own.

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

Mixergy discloses basic workforce diversity figures (approx. 25% female, 10% BIPOC as of 2023) and is backed by mission-aligned investors including Nesta and Barclays Climate Ventures, but publishes no formal ESG or sustainability report, no supply-chain due diligence disclosures, and no audited operational emissions data, which is typical for a ~40-person UK cleantech SME but limits scoring.

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

Third-party validation from the Energy Savings Trust, Energy Systems Catapult, National Physical Laboratory, and BRE (SAP Appendix Q listing) substantiates specific product-level claims, but the company has no public sustainability report, no GHG inventory, and key marketing figures (e.g., '95% CO₂ reduction', 'up to 60% bill savings') are presented without clearly stated methodology or boundary conditions.

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

No material controversies, regulatory actions, litigation, fossil fuel lobbying, or governance scandals were identified in public records; the company operates entirely in the clean-energy enablement space with reputable academic and institutional investors.
