All societies produce waste, though its characteristics and what happens to it depend on cultural, economic and political factors at local, national and global scales. New business models, technological innovations and social enterprise have the potential to reduce waste. Policymakers have a key role to play in supporting these efforts by fostering better communication between stakeholders; through regulation that prioritises reuse and quality recycling; and by encouraging resource efficiency through education, research and manufacturing initiatives.

Waste nationally and globally is increasingly problematic and challenging to policymakers. It is a problem that is increasing in scale and scope. It matters to all of us for a series of reasons:

• There is simply so much waste. In a country with a small land area and a large population, the sheer bulk of waste is in and of itself a problem;
• As humans congregate in cities around the world, the production of waste has become highly concentrated and that creates particular challenges for its collection and disposal:
• Much waste is harmful. The scale of that harm has become global. It harms both humans and the other species with which we share the planet. That harm comes in many forms.

In a circular economy, materials are more durable and easier to repair, reuse and recycle while waste is turned into a resource. In addition, processes from production to waste management become more resource efficient. Innovative business models enable companies to create value by selling services rather than products. Digital technologies will be pivotal in bringing about this systemic change. The European Union has to make the most of digital solutions for the benefit of a circular economy. This requires addressing the barriers to their uptake, enabling the free flow of data across borders, fostering trust in the data economy, and maximising synergies between the digital and circular economy agendas.

Our world economy is only 9.1% circular, leaving a massive ‘"circularity gap". This alarming statistic is the main output of this first Circularity Gap Report, in which we launch a metric for the circular state of the planet. The Circularity Gap Report provides a framework and fact-based to measure and monitor progress in bridging the gap, year on year. Being able to track and target performance via the Global Circularity Metric will help us engage in uniform goal-setting and guide future action in the most impactful way. Closing the circularity gap serves the higher objective of preventing further and accelerated environmental degradation and social inequality. The transition to circularity is, therefore, a means to an end. As a multi stakeholder model, a circular economy has the ability to unite a global community behind an action agenda, engaged and empowered both collectively and individually. Its systemic approach boosts capacity and capability to serve societal needs, by embracing and endorsing the best humankind has to offer: the power of entrepreneurship, innovation and collaboration.
