This collection features a selection of case studies, based on the global *Circularity Gap Reports*, that can mitigate climate breakdown by reducing virgin material consumption, waste and greenhouse gas emissions. The latest **[Circularity Gap Report 2023](https://www.circularity-gap.world/2023#download)** reveals that the global economy is now only 7.2% circular and outlines how circular solutions across four sectors can bring global planetary boundaries back within safe limits. 

In the six years of the *Circularity Gap Report*, the global economy has extracted and used unprecedented amounts of materials. The first edition of the *Report *in 2018 found that global circularity was 9.1% and it has decreased every year since—leaving a Circularity Gap of over 90%. If this trend continues, we will have to find more and better solutions to combat the negative effects of climate change. This is why we have identified case studies from across the globe—based on the needs of society and planetary health—that serve as real-world examples of the circular economy in action.

Circle Economy is a not-for-profit organisation working to accelerate the circular transition. Through the *Circularity Gap Reporting Initiative*, our mission is to deliver an annual global Circularity Metric that measures the state of the world economy and identifies key levers to transition to global circularity. With nature as our guide, we work alongside cross-sector stakeholders from academia, businesses, NGOs and governments to provide a powerful combination of practical and scalable interventions that transform circular opportunities into realities. 


To learn more about these interventions to accelerate the circular transition, read the latest [Circularity Gap Report 2023](https://www.circularity-gap.world/2023#download), as well as previous editions of the global [Circularity Gap Reports](https://www.circularity-gap.world/global).

The second biggest category in terms of resource use is the need for nutrition. Agricultural products such as crops and livestock require 21.8 billion tonnes yearly. Food products have short lifecycles in our economy, being consumed quickly after production.



Nutrition

Communication and connectivity is becoming an ever-more important aspect of today’s society, provided by a mix of equipment and technology ranging from personal mobile devices, to data centres. Increased connectivity is also an enabler of the circular economy, where digitisation can make physical products obsolete, or enable far better use of existing assets, including consumables, building stock or infrastructure.

🔊 Efficient design of ICTS

Regenerate strategies phase out hazardous or toxic materials and processes and substitute them with regenerative biomass resources. A circular economy aims to mimic natural cycles—by shifting to more regenerative farming practices, for example—while also maximising the share of circular biomass that enters the economy. Regeneration can happen both at the systems level (by designing regenerative processes) as well as at the product level (by switching synthetic to organic fertilisers, for example).

Regenerate

Cycle strategies aim to cycle and reuse materials at their highest value: they maximise the volume of secondary materials re-entering the economy, ultimately minimising the need for virgin material inputs and therefore also narrowing flows. Of course, virgin materials will always be needed to a degree: all materials degrade and can’t be cycled infinitely, use energy, and require blending with virgin materials to maintain strength and functionality.

<p>Tunisia has implemented a national strategy for the green economy, to identify possibilities for the development of economic activity in a sustainable way. The areas of focus are organic farming, eco-tourism, sustainable transport and infrastructure, sustainable eco-buildings, green industries, communication and information technologies, energy efficiency and energy use, renewable water conservation and water reuse, and finally, integrated waste treatment management. With these strategies, Tunisia hopes to stimulate economic growth and create jobs for citizens. Four principles are prioritised: the development of strong and inclusive growth, reduction of the current sensitivity of natural resources, adoption of integrated, decentralised and participatory governance, and promotion of citizens’ quality of life.&nbsp;</p>
