EulerESG: Automating ESG Disclosure Analysis with LLMs

TL;DR

EulerESG is an LLM-based system that automates ESG disclosure analysis by extracting standardized metrics from heterogeneous reports, enabling efficient benchmarking and exploration with high accuracy.

Contribution

We introduce EulerESG, a novel LLM-powered framework that explicitly models ESG standards for accurate, automated extraction and analysis of ESG disclosures from complex reports.

Findings

Achieves up to 0.95 accuracy in populating metric tables

Demonstrates practical end-to-end runtime performance

Effectively compares recent LLM models in ESG analysis

Abstract

Environmental, Social, and Governance (ESG) reports have become central to how companies communicate climate risk, social impact, and governance practices, yet they are still published primarily as long, heterogeneous PDF documents. This makes it difficult to systematically answer seemingly simple questions. Existing tools either rely on brittle rule-based extraction or treat ESG reports as generic text, without explicitly modelling the underlying reporting standards. We present \textbf{EulerESG}, an LLM-powered system for automating ESG disclosure analysis with explicit awareness of ESG frameworks. EulerESG combines (i) dual-channel retrieval and LLM-driven disclosure analysis over ESG reports, and (ii) an interactive dashboard and chatbot for exploration, benchmarking, and explanation. Using four globally recognised companies and twelve SASB sub-industries, we show that EulerESG can automatically populate standard-aligned metric tables with high fidelity (up to 0.95 average accuracy) while remaining practical in end-to-end runtime, and we compare several recent LLM models in this setting. The full implementation, together with a demonstration video, is publicly available at https://github.com/UNSW-database/EulerESG.
