While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software.

Company details
Written by the company
CarbonLens is the carbon data network built for the modern supply chain. We solve one of the most pressing operational challenges in corporate sustainability: the broken, repetitive, and inefficient exchange of emissions data between buyers and their suppliers. Today, sustainability managers at large enterprises spend months chasing suppliers for carbon data — sending questionnaires that get ignored, receiving responses in inconsistent formats, and struggling to produce audit-ready reports before regulatory deadlines. At the same time, suppliers are drowning in the same questionnaires from ten different buyers, answering identical questions in different formats every quarter. It is the same problem on both sides of the supply chain, and it has been unsolved for too long. CarbonLens fixes this with a single network. Suppliers enter their sustainability data once, build a verified Carbon Passport, and share it instantly with any buyer who asks. Buyers get structured, audit-ready Scope 3 data from their entire supply chain — automatically, without chasing a single email. Our platform covers the full compliance stack: Scope 1, 2, and 3 emissions tracking, Double Materiality Assessment, 11 reporting frameworks including CSRD, SECR, GRI, ISSB, CDP, and PACT, XBRL iXBRL export, AI Questionnaire Autopilot, and a cryptographically signed audit trail on every calculation. Security is built into our architecture from first principles — not added on. HMAC-SHA256 signatures on every data point, multi-tenant isolation enforced at the database level, EU data residency across all infrastructure, and a Vault SDK that ensures customer credentials never touch our servers. CarbonLens is used by sustainability managers, procurement directors, ESG teams, and supply chain leaders who need verified carbon data — not estimates — to meet their CSRD, SECR, and CDP obligations with confidence. Built in the UK. Deployed across Europe. Trusted by teams who cannot afford to get their numbers wrong.
