EPR Measurement

Establish clear and reliable calculation methodologies

Effective EPR schemes rely on harmonised, science-based methods for calculating reuse, recycling, and diversion rates.

Define and track key performance indicators (KPIs)

KPIs may include collection, recycling, reuse, repair, remanufacture, and diversion rates. These indicators should be comparable across jurisdictions and based on standardised inputs, such as packaging placed on the market versus collected for recycling, with data broken down into sufficiently granular material and product categories. Without granularity, broad categories (e.g. plastics) can mask poor performance, such as PET bottles carrying the weight for other low-performing plastics.

Enable monitoring, verification, and traceability of material flows

All entities involved in the EPR scheme (producers, PROs, waste management companies) must be registered and required to keep records of inputs and outputs., ensuring full traceability of materials throughout the system.

Ensure transparency in financial flows and institutional roles

Entities managing EPR fees and operations must disclose how funds are used. Financial flows should be traceable, and the roles of involved organisations, such as PROs, should be clearly defined.

Require third-party audits and data validation

To ensure credibility and prevent misreporting, jurisdictions should require independent assurance of reported data. Best practices include ongoing third-party audits, use of certified professionals, and adherence to domestic and international assurance standards. Sanctions should be in place for willful misrepresentation.

Make data open and accessible

Aggregated performance data should be publicly available by default, while maintaining business confidentiality. Published data should be up-to-date and hosted on a central website or open data platform. Transparency enables stakeholders to assess system effectiveness and identify areas for improvement.
