Evaluating the Global Plastic Action Partnership

We are evaluating the Global Plastic Action Partnership's progress toward reducing or improving the management of plastic waste and improving social, environmental and economic outcomes.

29/09/2025

Plastic waste is one of the greatest environmental crises facing our world today, with pollution generated set to double by 2040.

The Global Plastic Action Partnership (GPAP) is committed to scaling up plastic action globally to bring about effective, impactful responses to the global plastic pollution crisis.

Our evaluation will provide an independent and objective assessment of the GPAP and will provide important evidence to inform the design and implementation of current and future GPAP projects.

About the Global Plastic Action Partnership

Founded by the World Economic Forum in 2018, GPAP brings together governments, businesses, international organisations, and civil society for a coordinated, targeted, and evidence-based approach to accelerating national and international plastic strategies.

By carrying out this work, GPAP is helping to build a circular plastics economy that generates long-term social, environmental and economic benefits for all.

GPAP is supported by the UK’s Department for Environment, Food & Rural Affairs (Defra) through the Blue Planet Fund, alongside Global Affairs Canada, Coca-Cola and Nestle.

Our role

Jointly delivered with the Global Plastics Policy Centre at the University of Portsmouth, the evaluation will examine GPAP’s design, implementation, outcomes and overall impact. We will assess GPAP’s progress towards its goals of

  1. reducing or improving management of plastic waste, and
  2. improving social, environmental and economic outcomes.

We will pay particular attention to the relevance, efficiency, effectiveness, equity and sustainability of GPAP:

  • Relevance: we will address how well GPAP aligns with the needs and priorities of target communities and stakeholders
  • Efficiency: we will examine GPAP’s cost-effectiveness and resource utilisation
  • Effectiveness: we will measure the extent to which the project has achieved its stated goals and objectives
  • Equity: we will consider the fairness and inclusivity of GPAP’s benefits across different demographic groups.
  • Sustainability: we will evaluate the long-term viability and impact of the interventions.

We will also consider the role of GPAP in the context of the ongoing negotiations for a global treaty to combat plastic pollution.

Methods and approaches

Our evaluation design is structured in three modules:

  1. Assessment of reduction or improved management of plastic waste, including geographic case studies to provide for an estimation of the current situation today compared to prior projections, modelling of likely impact by 2030 and an assessment of effectiveness.
  2. Enhanced social, environmental and economic outcomes, including a quantification of current impact, modelling of likely impact by 2030 and country case studies to provide beneficiary feedback and identify factors influencing effectiveness.
  3. Project performance, process and VfM, addressed through: value for money (VfM); equity and gender equality, disability, and social inclusion (GEDSI); process; relevance, and; sustainability.

Outcomes and impact

Findings from our evaluation will be used to inform strategic decisions and enhance project implementation. It will also enable a greater understanding of the programme’s value for money and overall impact, as well as generating opportunities for collaboration, research and innovation between GPAP Partners.

Additionally, the findings will be an important contribution to our evaluation of the UK Government’s Blue Planet Fund, offering significant scope for synergies in terms of methods and lesson-learning across the Fund.
