Identification of biodiversity impacts

Practical guidance for preparing this disclosure. Use this card to identify the information to prepare, verify claims and organise supporting evidence. For exact requirements, always refer to the official Global Reporting Initiative source.

GRI 101: Biodiversity 2024 is effective for reports or other materials published on or after 1 January 2026 and replaces GRI 304: Biodiversity 2016.

Disclosure focus

Disclosure 101-4 requires an organization to explain how it determined which of its sites and which products and services in its supply chain have the most significant actual and potential impacts on biodiversity. The disclosure focuses on the determination process. Detailed information on the resulting sites, products and services and their biodiversity impacts is reported under Disclosures 101-5 to 101-8.

Sites include locations owned, leased or managed by the organization and other locations where it conducts activities. They also include sites where future operations have been announced but have not yet started, inactive sites, and relevant subsurface infrastructure such as underground tunnels, cables and pipelines.

The supply-chain assessment covers products and services from suppliers throughout the upstream supply chain, including suppliers beyond the first tier. The organization can additionally report information for entities downstream in its value chain where such information is available.

The organization should describe the methods and assumptions used, the threshold applied, any limitations or exclusions, and the sources and evidence used. It should also explain whether and how stakeholders were engaged to identify biodiversity impacts.

The organization should distinguish between primary, secondary and modeled data. When secondary or modeled data are used, it should identify the datasets, explain their limitations and state whether and how it plans to improve data accuracy.

To assess the significance of impacts, the organization should consider the severity of actual impacts and the severity and likelihood of potential impacts. Severity is assessed through scale, scope and irremediable character. Relevant supporting factors can include direct drivers of biodiversity loss, proximity to ecologically sensitive areas, threatened species, ecosystem condition and changes in ecosystem services.

Where it is not feasible to conduct a detailed assessment across all sites and all supply-chain products and services, the organization can first conduct a documented scoping exercise to identify where impacts are most likely to be present and significant. It should explain the scope, criteria, assumptions, limitations and exclusions of that exercise.

Reasons for omission are permitted in accordance with GRI 1 where the organization cannot comply with the disclosure or a specific requirement.

This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official Global Reporting Initiative source.

How to prepare it

1Cover owned, leased, managed and other activity sites, announced future operations, inactive sites and relevant subsurface infrastructure, plus products and services from suppliers throughout the upstream supply chain.
2Collect and reconcile the records for: Site determination process; Supply-chain determination process; Methods and assumptions; Threshold; Limitations and exclusions; Sources, evidence and data type; Stakeholder engagement; Impact-significance assessment; Initial scoping exercise.
3Use a documented scoping exercise only as an initial step where full detailed assessment is not feasible; do not convert it into a permanent first-tier or control boundary.
4Draft the response using the defined terms shown in the disclosure focus; do not substitute broader internal labels.
5Review the final wording against every requirement and the supporting governance or data records before sign-off.
Request the data

Request the disclosure evidence

Translate the disclosure into an internal business question — then adapt it to your organisation's own language.

Provide the complete site and upstream product/service universes, screening and detailed impact assessments, significance criteria and threshold, methods, assumptions, data and source register, stakeholder input, limitations and approved resulting lists.

Use the organisation's own role and document names, but preserve the defined GRI terms and the scope described above.

Better request

Provide the complete site and upstream product/service universes, screening and detailed impact assessments, significance criteria and threshold, methods, assumptions, data and source register, stakeholder input, limitations and approved resulting lists.

Draft your disclosure

Notes that turn data into a disclosure

LRA training templates — adapt them to your organisation, and check the official source before sign-off.

Method note

Assess actual impacts by severity and potential impacts by severity and likelihood. Use direct drivers, sensitive-area proximity, threatened species, ecosystem condition and ecosystem services as supporting factors rather than substitutes for significance.

Context note

GRI 101-4 reports the determination process. Report the resulting site, product, service and impact details under GRI 101-5 to GRI 101-8.

Evidence pack to prepare

Common reporting gaps

Presenting the resulting list as the core requirement instead of the determination process.Limiting sites to owned or active operational locations.Limiting supply-chain assessment to direct suppliers.Mixing biodiversity impacts with dependencies or financial risks.Using exposure screening alone as the final impact-significance assessment.Failing to distinguish primary, secondary and modeled data.
