Measuring our impact
Anchored on our Impact Metrics Framework, we measure our progress to provide a full and accurate representation of our impact
Building transparency through independent assurance
The Alliance exists to develop and demonstrate projects that help end plastic waste in the environment and advance towards plastics circularity. To effect change requires nurturing individual projects and programmes while creating enabling conditions for future replication –this requires ongoing trusted engagement and data-driven dialogue across various stakeholder groups to catalyse greater movement towards our mission.
Our Impact Metrics Framework provides a consistent approach through which we can quantify, track, and report our progress. The framework outlines a suite of top-level metrics across five core and two associated impact areas most relevant to the work that we do.
Ensuring that we have robust processes to measure and independently verify our work is integral to providing an accurate view of our progress and to inform such dialogue. We continue our multi-year journey to strengthen our reporting by working closely with our funding recipients to ensure alignment with our reporting and evidencing requirements, and in seeking independent Limited Assurance.

Evolving the way we measure our impact
In 2024, we continued to seek independent Limited Assurance for those metrics prioritised as ‘assurance-ready’ as well as an assessment of reasonableness in approach for those that we will continue to develop. Against the backdrop of the varied projects and solutions that we are testing and implementing, and challenging environments and systems, we are committed to the path of continuous improvement so we can present a full set of independently assured results in future reporting years.
