World Benchmarking Alliance+NAT.B12.EE Plastic Waste Reporting+methodology

WBA analysed all publicly available group-level disclosure in English on the applicable group website, which was predominantly annual reports and sustainability reports. Draft assessments were then sent to each company inviting them to provide feedback. This feedback could include additional publicly available group disclosure published. These were then reviewed and finalised. Final assessments were then shared with each company before being published online.

For this metric the focus is on the most relevant part of its value chain for each company.
