Foco de la divulgación
Disclosure 303-1 requires an organization to describe how it interacts with water, including how and where water is withdrawn, consumed and discharged. It also describes the water-related impacts it has caused or contributed to, or that are directly linked to its operations, products or services through business relationships.
The organization explains the approach used to identify these impacts, including the scope and timeframe of assessments and the tools or methodologies applied. The assessment should consider actual and potential future impacts on water availability, quality and accessibility across relevant operations and value-chain relationships.
The organization describes how identified impacts are addressed, how it works with stakeholders to steward water as a shared resource and how it engages suppliers or customers with significant water-related impacts. The description should distinguish impacts caused, contributed to and directly linked through business relationships.
Where water-related goals and targets form part of the management approach, the organization explains how they were set and how they relate to public policy and the local context of each area with water stress. Meaningful targets can be informed by sustainable catchment thresholds, social context, public-sector targets and stakeholder advocacy.
GRI additionally recommends providing an overview of water use across the value chain and listing the specific catchments where the organization causes significant water-related impacts. Quantitative withdrawal, discharge and consumption figures are reported separately under Disclosures 303-3, 303-4 and 303-5.
