A framework for reporting non-financial sustainability performance.
Last reviewed 10 August 2026
Environmental, Social, and Governance — ESG — is the framework the capital markets built to report the non-financial performance the investor and the regulator now ask for alongside the financials, and it sits above the operational EHS data the way the financial statement sits above the ledger. The reporting standards are consolidating: the GRI is the multi-stakeholder standard, the SASB is the investor-materiality standard, the TCFD is the climate-financial-risk standard, the ISSB merged the SASB and the TCFD into the IFRS Sustainability Disclosure Standards, and the EU CSRD is the mandatory regime that turns the disclosure into law for the in-scope company. The EHS programme is the source of the data underneath — the emissions, the water, the waste, the injuries, the diversity — and the ESG report is the disclosure on top.
ESG is distinct from the environmental management system under ISO 14001, though the two overlap and most mature programmes run both. ISO 14001 is the operational system that runs the site and produces the data; ESG is the disclosure framework that aggregates the data across the company and reports it to the market, and the gap between them is the gap the auditor and the investor both read. The honest ESG report is the one where the disclosed number traces back to the operational record — the Scope 1 to the meter, the TRIR to the 300 log, the water to the withdrawal record — and the report that cannot trace is the one that becomes the greenwashing claim the regulator and the plaintiff pursue. The CSRD assurance requirement is what forces the trace. See ISO 14001.
