PLP: Plastic Leakage Project

The Plastic Leak Project (PLP), a pre-competitive multi-stakeholder initiative co-founded by Quantis and ecodesign center EA in partnership with 35 public, private and scientific organizations, delivers the first science-based methodology to map, measure and forecast plastic leakage along the value chain. These insights provide sustainability managers and corporate decision-makers with a strong foundation to translate their commitments to tackle plastic pollution into effective strategies and actions that meaningfully address plastic leakage.

Following a yearlong collaboration and rigorous testing of the methodology through pilot projects with Arla Foods and textile brand Sympatex Technologies, the full PLP Methodological Guidelines and accompanying Brief are now publicly available.


The PLP Guidelines shift the plastics conversation from sounding the alarm to driving meaningful change with robust metrics.


Bolster business value with a plastic leakage assessment

As pressure from investors, consumers and governments rise, companies have made bold commitments to tackle plastic pollution in their value chains. Until now, businesses have lacked the tools and metrics to identify where plastic leakage is happening and which actions will be most meaningful.

Thanks to the PLP Guidelines, companies can identify areas of greatest impact and develop targeted strategies that enable them to address these business risks, design better products, innovate supply chain solutions, track progress, communicate credibly on their efforts, and strengthen brand reputation. This assessment is the first step in developing a science-based plastics strategy.
