AIZEN ESG Transparency Index Measures the traceability of sustainability claims using a fully published, reproducible methodology. Assesses whether public claims can be independently traced to documented evidence, without scoring performance itself.

Starting September 2026, the rules change. The EU’s new framework will require every environmental claim to be backed by documented evidence, before it’s communicated - not after. Here’s what’s coming, what it means for your organization, and how to prepare now.

The ESG data market is projected to exceed $5 billion by 2027. But not all ESG data serves the same purpose.

ESMA's 2025 review of Year 1 CSRD reporting found that 40% of major European companies failed to properly demonstrate their materiality assessment process. Supply chain evidence was identified as the weakest compliance area.

We're thrilled to announce that Robert Myhre, one of Norway's foremost experts on public procurement law, has joined AIZEN as an Advisory Board Member.

€50M in regulatory fines. One CEO resignation. Zero fraud. New AIZEN Newsroom case study: What the DWS investigation reveals about the gap between ESG promises and verification infrastructure.

Episode 1: What auditors actually look for in your ESG data. Data linage, Conrol gaps, Materiality, Third-party claims, Public data consistency. These are the exact checks companies need to prepare for, and the foundation we’re building at AIZEN.

AIZEN collaborated with a Big4 firm to evaluate whether ESG evidence traceability could be automated at assurance-grade quality using only publicly available data. The pilot analyzed 211 ESG claims across ESRS E1–S1 topics. Results showed only 3.8% of claims were verifiable using public data, while 91.5% required internal sources and 4.3% needed clarification. This exposes a major traceability gap facing companies under CSRD.
