Formula
Total pollutants removed = sum of pollutant mass removed from each included environmental medium during the reporting period.Apply the source-defined TNFD Recommendations method only within the disclosed location, ecosystem and value-chain boundary. Annex 2 metric A2.2 identifies a reportable outcome quantity, expressed as total pollutant mass removed from environmental media. It is retained as an optional additional TNFD metric and structured by medium and pollutant to preserve material environmental differences.

Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Source-edition basis: Recommendations of the Taskforce on Nature-related Financial Disclosures, September 2023.
- Identify the environmental media from which pollutants were removed.
- Describe the pollutant classification and mass-measurement or estimation method.
- State the organizational, operational and geographic boundary for pollution-control activities.
- Disclose use of direct measurement versus proxy or estimated methods.
Record-specific limitations
- A total mass can obscure differences in pollutant toxicity, persistence, concentration and environmental significance.
- Reported removal depends on the pollutant identification, measurement and estimation methods applied.
- The source excerpt does not specify whether removed pollutants must be reported by individual pollutant or pollutant class.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
