Climate Impact & Solution35%88

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.

First Solar's panels are projected to displace approximately 78 million metric tons of CO2e per year over their 30+ year product life, and the company's CdTe technology has a lower manufacturing carbon footprint and up to 5x greater energy return on energy invested versus conventional crystalline silicon — though cadmium is a regulated hazardous material requiring careful lifecycle management.

Decarbonization & Targets20%78

Credible, science-based targets (SBTi), a real net-zero plan with progress to date, and CDP disclosure — not just a dated press release.

In 2023, First Solar became the first major solar manufacturer to have science-based and net-zero targets validated by SBTi, committing to a 34% absolute reduction in Scope 1 and 2 emissions by 2028 (vs. 2020 baseline) and net-zero by 2050, plus RE100 membership targeting 100% renewable electricity for manufacturing by 2028 — but Scope 3 target coverage and progress data remain limited.

ESG & Operations15%72

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

First Solar holds an MSCI ESG rating of AA, an ISS ESG 'Prime' rating, a CDP Water Security score of A-, and claims the solar industry's only manufacturing footprint to have completed social audits by a credible third party, with 88% waste diversion and 95% material recovery from recycled panels in 2024 — though labor standards at overseas facilities (Malaysia, Vietnam, India) require ongoing scrutiny and the cadmium hazard in manufacturing is a persistent worker-safety concern.

Transparency & Verification15%75

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

First Solar publishes annual sustainability reports aligned with GRI, TCFD, and SASB standards, submits to CDP's Climate Change questionnaire, and has SBTi-validated targets — and the 2025 Corporate Responsibility Report references third-party social audits and verified recycling recovery rates — but Scope 3 emissions disclosure and independent financial assurance of GHG data are not fully comprehensive.

Integrity15%74

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

No major governance scandals, fossil-fuel lobbying, or conflict-zone involvement have been identified; the primary integrity concern is the persistent cadmium-related hazardous-material risk in manufacturing and end-of-life disposal, which is publicly acknowledged and managed but remains a reputational and regulatory exposure, particularly as the global installed base of CdTe panels ages toward end-of-life.

Why it's on ClimateTicker

First Solar is one of the few Western solar manufacturers at meaningful scale, and its core product — thin-film cadmium telluride (CdTe) panels — directly displaces fossil-fuel electricity generation with a notably lower manufacturing carbon footprint than crystalline silicon. The company has real SBTi-validated targets, active CDP disclosure, and a proprietary recycling program, making its climate credentials substantially more credible than most peers. The principal residual risks are the hazardous-materials profile of cadmium in manufacturing and end-of-life scenarios, scope-3 disclosure gaps, and the fact that part of its manufacturing footprint still relies on grid electricity in carbon-intensive jurisdictions.

mitigationFirst Solar designs, manufactures, and sells thin-film CdTe photovoltaic modules primarily to utility-scale solar project developers and independent power producers, and also develops, finances, and sells large solar projects through its systems business segment.

Controversy & Greenwashing Watch

mediumCadmium hazardous material — manufacturing & end-of-life risk

CdTe modules contain cadmium, a substance regulated as hazardous by the EPA; while studies show lifecycle Cd emissions from CdTe PV are orders of magnitude below coal power, landfill leaching and fire-release scenarios remain scientifically debated end-of-life risks as the global installed base grows.pmc.ncbi.nlm.nih.gov

lowScope 3 emissions — limited disclosure

First Solar's SBTi-validated targets cover Scope 1 and 2 only, and its Scope 3 supply chain and product-use emissions disclosures are incomplete relative to best practice, a gap flagged in its own SEC filings as a regulatory compliance risk.sec.gov

lowOverseas manufacturing labor risk

With factories in Vietnam, Malaysia, and India, First Solar faces ongoing supply chain labor scrutiny; the company claims third-party social audits but admits in SEC filings that supplier violations of its Code of Conduct remain a residual ESG risk.sec.gov
