Climate Impact & Solution35%52
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 directly enables wildfire containment — a genuine climate-adaptation service as fire seasons grow 78 days longer than in the 1970s — but the product does not cut emissions, and independent research documents significant ecological harm to aquatic species and the presence of toxic heavy metals, limiting the net climate-resilience credit.
Decarbonization & Targets20%18
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 or CDP disclosure was found; the company's ESG reports reference SASB and TCFD frameworks and aspirations to reduce carbon emissions, but no quantified, science-based reduction targets with interim milestones or third-party validation have been publicly disclosed.
ESG & Operations15%38
Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.
The company has a published Code of Ethics, a safety program, and incremental investments in dust-collection technology, but faces material product-linked ESG risks including AFFF/PFAS multi-district litigation with over 6,000 pending cases, documented aquatic toxicity of PHOS-CHEK formulations, and undisclosed proprietary ingredients that obstruct independent safety assessment.
Transparency & Verification15%30
Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.
Three annual sustainability reports have been published using SASB and TCFD frameworks, which is a positive trajectory for a company of this size, but proprietary ingredient secrecy for PHOS-CHEK, no CDP questionnaire response found, no third-party-assured emissions data, and no public Scope 3 accounting substantially undercut disclosure quality.
Integrity15%42
Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.
Perimeter is named in a massive AFFF/PFAS multi-district litigation (inherited via the Solberg acquisition) alleging groundwater and drinking water contamination; a USC peer-reviewed study found toxic heavy metals in PHOS-CHEK at hundreds to thousands of times drinking-water limits; California media (CapRadio, July 2025) reports mounting lawsuits and scrutiny over retardant drops on residential areas; and the company declined to comment on the heavy-metals research, raising accountability concerns.
Why it's on ClimateTicker
Perimeter Solutions sits on a climate platform because wildfire suppression is an adaptation service in a world where climate change is lengthening fire seasons and doubling acreage burned; its PHOS-CHEK products protect lives, property, and forests. However, the company's core value proposition is tied to worsening climate conditions rather than reducing their cause, its flagship product carries unresolved ecological toxicity concerns (heavy metals, aquatic harm), and its own operational decarbonisation disclosures remain early-stage and self-reported, with no SBTi or CDP validation found.

Controversy & Greenwashing Watch
PHOS-CHEK's full ingredient list remains undisclosed as a trade secret, hampering independent environmental and health assessment; California regulators and researchers are calling for greater transparency as drops on residential neighborhoods surge.capradio.org
A peer-reviewed USC study found that PHOS-CHEK LC-95W contains chromium, arsenic, lead, and other toxic metals at concentrations 4–2,880 times above EPA drinking water limits, raising ecological and human health concerns.thenewlede.org
Perimeter Solutions declined to respond to a media request for comment from The New Lede regarding the USC heavy-metals study, raising concerns about corporate accountability and transparency.thenewlede.org
Research documents that PHOS-CHEK is lethal to rainbow trout, Chinook salmon, and other aquatic species upon waterway contact; the U.S. Forest Service has previously been successfully sued over retardant drops near water, and accidental misapplications continue to occur.ehn.org
Perimeter is a defendant in MDL proceedings with over 6,000 cases alleging groundwater and drinking water contamination from PFAS chemicals in AFFF firefighting foam, stemming from its 2019 acquisition of The Solberg Company.sec.gov
