Climate Impact & Solution35%72
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.
HJT solar module manufacturing is a genuine emissions-avoidance business at the product level, with European-made modules carrying a lower embodied-carbon footprint than Chinese imports, but the company's collapse and liquidation of its manufacturing assets means real-world GW-scale impact was never achieved.
Decarbonization & Targets20%38
Credible, science-based targets (SBTi), a real net-zero plan with progress to date, and CDP disclosure — not just a dated press release.
Meyer Burger self-reported a 50% Scope 1+2 reduction target by 2030 (2021 baseline) and a net-zero goal by 2050, and achieved a modest 6.7% Scope 1 reduction 2022–2023, but no SBTi validation of targets was confirmed, CDP disclosure status is unclear, and the company's insolvency has rendered forward-looking targets moot.
ESG & Operations15%42
Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.
Meyer Burger published GRI-aligned sustainability reports and joined the UN Global Compact, but its 2024 annual report was repeatedly delayed and never formally published before insolvency; mass layoffs of over 900 workers across US and German sites in 2025 represent a significant social governance failure, and a workforce sexual harassment flag appears in third-party ESG databases.
Transparency & Verification15%35
Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.
The 2023 Sustainability Report followed GRI standards and disclosed Scope 1 and 2 emissions with some granularity, but Scope 3 coverage was thin, no independent third-party assurance of emissions data was confirmed, the 2024 annual report was never published before collapse, and SBTi validation — flagged by analysts as needed — was never obtained.
Integrity15%45
Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.
Meyer Burger's collapse involved alleged contract breaches (DESRI termination citing breaches), an unpaid US Customs duty of $5.1 million, repeated delays to financial disclosures, a fivefold increase in net losses concealed until late 2024, and leadership instability including an abrupt CEO resignation — collectively constituting serious governance and financial integrity failures.
Why it's on ClimateTicker
Meyer Burger manufactures high-efficiency heterojunction (HJT) solar cells and modules, meaning its core product genuinely displaces fossil-fuel electricity generation — a clear mitigation play. However, the company collapsed into insolvency in 2025 (Chapter 11 in the US, debt moratorium in Switzerland, German subsidiaries insolvent), wiping out its manufacturing base and calling into question whether any near-term climate impact will actually be delivered. Investors should treat this as a cautionary tale of a genuine clean-tech vision that failed on execution and capital structure, not on mission.
