ESRS Standards Explained: The Twelve Building Blocks of CSRD

The European Sustainability Reporting Standards (ESRS) operationalize . There are two cross-cutting standards and ten topical standards, developed by EFRAG and adopted by the European Commission.

This guide walks through each ESRS at a working level: what it requires, the key datapoints, and where it interacts with other standards.

Cross-cutting: ESRS 1 and 2

ESRS 1 (General Requirements): the how — reporting principles, boundaries, materiality methodology, connectivity to financial statements, disclosure conventions.

ESRS 2 (General Disclosures): the what — governance, strategy, impacts-risks-opportunities, policies, actions, targets, and metrics that apply across all topical standards.

Environmental: E1–E5

E1 Climate change: emissions /2/3, transition plan, energy consumption. Effectively mandatory for every reporter.

E2 Pollution: air, water, soil pollutants; substances of concern.

E3 Water and marine resources: consumption, discharge, water-stressed areas.

E4 and ecosystems: impacts, dependencies, sensitive areas.

E5 Resource use and : inflows, outflows, waste.

FAQ

Frequently asked questions

Which standards are always applicable?

ESRS 1 and ESRS 2. Topical standards apply where material.

Is ESRS the same as GRI?

No. ESRS is EU-mandated and heavier on financial-materiality integration. Reporters can cross-map GRI to ESRS but not substitute.

How many datapoints total?

~1,100 across all standards. Typical reporters disclose against 300–500 based on materiality.

ESRS-native reporting with datapoint-level coverage

Vuneli maps every disclosure to its ESRS datapoint ID, tracks completeness, and exports XBRL — so your CSRD file assembles itself.
