Disclosure focus

This disclosure asks an organisation to explain how it manages the impacts linked to the water it releases back into the environment. In practice, the focus is on the controls, processes and oversight used to reduce harm from discharges, rather than on describing water use in general. The organisation should make clear what it does to identify, prevent, limit and respond to any adverse effects associated with its wastewater or other water releases.

The practical emphasis is on the parts of the business where discharges can create material impacts, and whether management is applied consistently across operations or only at selected sites. A useful explanation would show how the organisation decides which locations, activities or discharge points need attention, and how it monitors performance and follows up where risks are higher.

* This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official GRI source.

  • State whether the characteristics of the receiving water body were taken into account.

LRA working checklist - paraphrased; see official source

How to prepare
  1. Start by listing every site or operation that sends treated water out of the business, then decide which of those locations the disclosure will cover. Keep the scope note clear so reviewers can see what is in and what is left out.
  2. For each covered location, define the quality benchmark you used for the discharge. Record whether it came from a local rule, an internal company rule, a sector benchmark, or another basis, and keep the wording specific to each site where it differs.
  3. If a site has no local discharge rule, explain the method used to set the benchmark there. Also note any company-made water quality guidance and any industry benchmark you relied on, using enough detail for someone else to follow the logic.
  4. Check whether the receiving water environment was part of the decision. If it was, capture what aspect of that waterbody profile you looked at and how it influenced the benchmark or the final description.
  5. Gather the supporting records before drafting the disclosure: policy papers, technical notes, site-level approvals, legal or compliance references, and any assessment papers showing how the benchmark was chosen. Make sure the evidence matches the wording you plan to report.
  6. Prepare the final text by setting out the benchmark description and the method used to determine it, then add any exclusions, site-specific differences, or changes from prior reporting. Before filing, compare the draft with the official source to confirm you have covered every required point and have not added anything extra.

Request the wastewater discharge standards evidence

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

What standards, methods, and site-level considerations are being used to manage wastewater discharge quality at our facilities?

Use your organisation’s own terms first, then map them to the reporting wording. For example, ask for wastewater, trade effluent, process water, or site discharge records if those are the terms used internally. Keep the request in operational language and check the source material before sign-off.

Weak request

Please provide the GRI 303-2 evidence for effluent discharge standards and the methodology for determining standards, including internal guidelines, sector-specific standards, and receiving waterbody considerations.

Why it fails: It uses framework language that many operational teams will not use day to day, so it is harder to action. It also bundles several ideas into a compliance-style ask without telling the owner what records to pull, which sites or systems to check, or what format to return.
Better request

Please send the wastewater or trade effluent discharge standards pack for [period] and [sites]. Include the current limits or site rules, how they were set, what we do at sites with no local discharge limit, any internal water quality guidance, any sector guidance used, and whether the receiving waterbody or outfall was considered. Please add the source file, version, and approver.

Hi [name/team] — could you send the wastewater/trade effluent discharge standards pack for [period] for [sites]? Please include the limits or site rules used, how they were set, any internal guidance, any external/sector benchmarks used, and whether the receiving waterbody/outfall was considered. Also share the source file and approver. Please adapt to your own terms and check the source material before sign-off. Thanks.
Industry examples
Food and beverage manufacturing

Context. Sites discharge process water and cleaning water to sewer under local permits and site operating rules.

Adapted request. Please share the trade effluent and process water discharge pack for [period] across [sites]. Include the current site limits, how they were set, any internal hygiene or water quality rules, any industry guidance used, and whether the sewer or receiving water conditions were considered.

Example response. For Plant A and Plant B, the pack includes the permit extracts, the site discharge procedure, a technical note explaining how limits were set from permit conditions and internal engineering checks, and a memo confirming that sewer capacity and local receiving conditions were reviewed. Plant C has no local discharge limit, so the site used the corporate water quality guide and a benchmark from the sector association.

Mining / extractives

Context. Sites manage mine water and treated discharge to a nearby watercourse, with some remote locations lacking local discharge thresholds.

Adapted request. Please provide the mine water discharge standards pack for [period] for [sites]. Include the discharge limits or site operating rules, how they were determined, the approach used at remote sites with no local limit, any internal water quality guidance, any sector benchmark, and whether the river or catchment conditions were considered.

Example response. The response includes site discharge plans, lab-based limit summaries, a technical memo for remote sites showing how the benchmark was set using internal guidance and regional practice, and a note confirming that river flow and catchment sensitivity were reviewed before finalising the site rules.

The full request pack — response form, data table, evidence metadata and sign-off — is in the Download Centre.

Draft your disclosure

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

Method note

Explain which discharge-quality benchmarks were used, how each one was chosen, and how you dealt with sites that had no local discharge rules, including any company-made guidance, outside sector benchmarks and any assessment of the receiving water.

Context note

Set out what the figures mean by showing the standards used to manage effluent quality and how they differ by site, so readers can see whether the approach was locally driven or based on broader internal or sector practice.

Fluctuation statement

If the standards changed from one site or period to another, note whether that was because local rules differed, a different benchmark was selected, or the receiving water conditions led to a different approach.

Examples
Illustrative examples

Synthetic, written by LRA — not from a company report, not text from any standard.

Food processing · synthetic · written by LRA

Synthetic illustration only. We set our discharge controls by starting with the legal limits that apply to each site, then tightening them where our own water team judged the local river or estuary to be more sensitive. For sites with no local rulebook, we used the same internal water-quality guide across the group, with extra checks where the receiving water was already under pressure.
- Our minimum release conditions covered pH, temperature, suspended solids, nutrients and selected process chemicals; the exact thresholds varied by site and were approved through our environmental management process.
- In 6 of 8 sites, the local permit was the main basis for the limit set; in the other 2 sites, we applied our internal guide because no local discharge limit existed.
- We also looked at the waterbody taking the effluent: 5 sites discharged to rivers with low seasonal flow, 2 to estuarine waters and 1 to a municipal treatment system, and that profile influenced how strict we made the site controls.
- Sector guidance for food and drink manufacturing was reviewed alongside the permit conditions, but we did not adopt any sector benchmark without checking it against site-specific conditions.

This example shows how a reporter can explain the basis for effluent controls, including internal rules, sector guidance and the condition of the receiving water, without using standard language.
Chemicals · synthetic · written by LRA

Synthetic illustration only. Our discharge criteria were built from the permit conditions that apply at each plant, then aligned with a group-wide water standard that we wrote for operations in places without a local discharge framework. Where we had no local limit to follow, we used that internal standard and checked it against the nature of the water receiving the outflow.
- The internal standard set minimum values for acidity, oil and grease, metals, and oxygen-demanding substances; it was created by our environmental specialists using past monitoring results, treatment capability and risk review.
- We considered chemical-industry guidance on wastewater quality, but only as a reference point; it did not replace site controls or the group standard.
- Of our 10 plants, 7 relied mainly on local permit conditions and 3 used the group standard because no local discharge requirement was in place.
- The receiving waters were part of the decision: 4 plants discharged to small inland streams, 3 to larger rivers and 3 to a coastal outfall, and we applied tighter internal checks where dilution was lower or ecological sensitivity was higher.

This example shows a different way to describe the same disclosure, with emphasis on how internal criteria were developed and how the receiving water influenced the final limits.

From a number to a disclosure

What separates a figure from a disclosure.

Basic

I set our discharge limits at a level that reflects local rules and our own water-quality guidance.

Better

I set our discharge limits using local permit conditions where they exist, our internal water-quality criteria where they do not, and sector guidance, and I also checked the receiving water’s condition.

Best

For this year, I applied site-by-site discharge limits based on local permit terms or, where none existed, our internal water-quality criteria and sector guidance, and I took account of the receiving water’s condition; compared with last year, one site tightened its limit after a routine review showed the river was more sensitive than we had first assumed.

Evidence in Marfrig Global Foods S.A.’s report

What the report shows

Marfrig Global Foods S.A.'s Integrated Report 2024 includes a covered datapoint on effluent management, stating that standards are met and that there is an online monitoring system for effluent (p.83). However, other narrative items related to this disclosure are not found or unclear, with no quotable evidence provided elsewhere in the report. This suggests limited detailed information on the broader aspects of the disclosure beyond the effluent monitoring system.

Check your understanding
A manufacturing site sends treated wastewater to a river where the local permit only covers a few pollutants. The team has also set extra internal limits for temperature and suspended solids because the river is already under pressure.What should the preparer decide to include when explaining how the discharge limits were set?
Model answer. They should describe the minimum quality limits used for the outflow, explain the basis for setting those limits, and make clear whether they came from local rules, internal guidance, sector practice, or a mix of these. If the river’s condition influenced the choice, that should also be stated.
Why this matters. The explanation should show both the limit itself and the reasoning behind how it was chosen.
A site in a country with no local wastewater discharge rules uses a group-wide standard that was written by the company’s environmental team. The standard was based on a review of similar operations and a benchmark from the sector.How should the preparer explain the basis for the site’s discharge standard?
Model answer. They should say that, because no local discharge rule applied, the site used an internally set benchmark. The explanation should describe how that benchmark was developed and note any sector practice that informed it.
Why this matters. Where local rules are absent, the report should still explain the source and logic of the site’s own benchmark.
A food-processing plant discharges into a small lake used for recreation and wildlife. The environmental team checked the lake’s sensitivity, seasonal flow, and existing nutrient levels before finalising the discharge limits.What judgement should the preparer make about the receiving waterbody information?
Model answer. They should include a clear statement on whether the lake’s characteristics were taken into account when setting the discharge limits. If they were, the report should briefly describe the features considered and how they affected the standard.
Why this matters. The report should show whether the receiving water’s condition shaped the discharge approach.
A group has three facilities: one follows a municipal permit, one uses a company-made water quality guideline, and one in a specialist industry also aligns with a sector benchmark. The draft report lists the limits but not where each one came from.What should the preparer do before sign-off?
Model answer. They should add a plain-language explanation for each facility or site type showing the basis for the discharge limits, including any internal guideline, sector benchmark, or local requirement used. The narrative should also explain how the limits were determined and whether the receiving water was considered where relevant.
Why this matters. A complete disclosure links each discharge limit to its source and the reasoning behind it.

Questions this page answers
What do I need to gather for GRI 303-2 Water and Effluents before I start drafting the disclosure?

Use the page’s prep list as your starting point: effluent quality floor, how limits were set, any sites with no local rule, company water rules, industry standards reviewed, and the receiving water context. The page also has a step-by-step preparation section to help you turn that into a draft. ↑ section

How do I use the step-by-step 'how to prepare' section for GRI 303-2 Water and Effluents?

Work through the steps to move from source data and methodology into a disclosure draft. The page is designed as practitioner guidance, so it helps you organise the information rather than just list the topic. ↑ section

What data owner should I ask for the GRI 303-2 Water and Effluents inputs?

The page does not assign a specific role, but it is written for sustainability/ESG managers, HR or data owners, and assurance reviewers to use together. In practice, you would route the prep items and evidence pack to whoever holds the water and effluent data and the supporting methodology. ↑ section

How do I decide the scope and methodology for GRI 303-2 Water and Effluents using this page?

Use the page’s methodology prompts: how limits were set, any company water rules, industry standards reviewed, and the receiving water context. Those items help you explain the basis for the disclosure in a way that is ready for review. ↑ section

What should go into the evidence pack for GRI 303-2 Water and Effluents?

The page includes a five-item evidence pack for assurance readiness. Use it to assemble the documents and records that support the claims, the methodology, and the reported figures before you finalise the disclosure. ↑ section

What are the six assurance claims I need to verify for GRI 303-2 Water and Effluents?

The page says there are six assurance claims to verify, each with a claim, risk, and evidence prompt. Use those checks to test whether the draft is supported and whether the evidence pack is complete. ↑ section

What are the common reporting gaps or mistakes for GRI 303-2 Water and Effluents?

The page lists common reporting gaps and mistakes so you can spot weak points before sign-off. It is useful for checking whether the draft has enough context, evidence, and consistent methodology. ↑ section

Can I use the synthetic example on the GRI 303-2 Water and Effluents page as a template for my own disclosure?

Yes, as a drafting aid only. The page includes synthetic illustrative example disclosures and a quantitative table, so you can see how the information might be presented, but you should replace it with your own data and context. ↑ section

What should the draft output for GRI 303-2 Water and Effluents look like?

The page gives draft-output ideas including visualisation options, narrative starters, and a GRI content-index line. That helps you turn the underlying data into a disclosure-ready draft rather than a raw data dump. ↑ section

How do I use the workbook and printable PDF from the GRI 303-2 Water and Effluents download centre?

The download centre includes a Prep & Assurance workbook in .xlsx format and a printable Library Card in .pdf format. Use the workbook to organise the prep and assurance checks, and the PDF as a reference copy for review or sharing. ↑ section

Is the data I prepare for GRI 303-2 Water and Effluents reusable for ESRS E3 (Water and Marine Resources)?

The page says ESRS E3 is the closest correspondence, so the data may be reusable across both. It does not say the requirements are identical, so you still need to check the other framework separately. ↑ section
