Circle Economy and ICLEI have partnered up to initiate the go to knowledge hub of case studies about the circular economy in cities. The Cities Collection is a repository of case studies that demonstrate the role of cities in the circular transition, and includes policies, business cases and research articles. Cases in the Collection flow into an ecosystem of digital products which support users in transitioning cities to circularity, for example [Ganbatte](https://ganbatte.world/cities/) and <a href="https://circulars.iclei.org/" target="_blank">ICLEI Circulars</a>, both part of the <a href="https://circulars.iclei.org/circle-lab-for-cities/" target = _blank">Circle Lab for Cities Programme.</a>

This collection features a selection of case studies, mainly based on the [2024 Circularity Gap Report](https://www.circularity-gap.world/2024). 

In this year’s Report, we shift from exploring the what to the how: exploring the different ways that we need to ‘change the rules of the game’ and create a set of conditions that discourage the overshoot of planetary boundaries and ‘undershoot’ of human development. This process has resulted in us spotlighting 12 of the original 16 solutions, highlighting the country profile that they are most relevant to, as well as placing people at the centre of this story for the first time. Based on extensive interviews and desk research, this Report aims to show governments and industry leaders that if they want to turn theory into action and scale an economy that delivers on needs within the safe limits of the planet, they need to dismantle harmful entrenched processes and align enabling elements. 

[Circle Economy](https://www.circle-economy.com/) is a global impact organisation with an international team of passionate experts based in Amsterdam. We empower industries, cities, and nations with practical and scalable solutions to put the circular economy into action. Our vision is an economic system that ensures the planet and all people can thrive. To avoid climate breakdown, our goal is to double global circularity by 2032. 

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. 

To learn more about these interventions to accelerate the circular transition, read the [latest Circularity Gap Report 2024](https://www.circularity-gap.world/2024), as well as previous editions of the global [Circularity Gap Reports](https://www.circularity-gap.world/global).

Grow countries globally account for 55% of all raw material extraction and 52% of the material footprint, while housing around 37% of the global population.

These are larger Southeast Asian countries and countries in Latin America and Northern Africa, as well as those with an economy in transition in Eastern Europe, the Caucasus, and Central Asia.

Examples include :
- China
- Indonesia
- Brazil
- Mexico
- Vietnam
- Myanmar
- Egypt, ...

Large contribution to the overshoot of planetary boundaries—largely due to the consumptions of local materials in higher-
income (Shift) countries: these countries contribute 50% of climate change, 62% of nitrogen, 60% of phosphorus, 53% of freshwater use and 42% of land use change.

Rethink

High-level changes to policy and practice (such as taxation systems, investment and procurement guidelines and criteria) that disincentivize activities that perpetuate linear economic systems, as well as vision-setting (goals, roadmaps) to catalyze
action on circularity across the city

Eliminate linear incentives and set goals and incentives for circularity

The food system nourishes populations and employs 50% of the global workforce, but:
- it currently drives a quarter of the overshoot on the climate change planetary boundary due to its greenhouse gas (GHG) production, 
- animal farming alone uses over one-quarter of all land, equivalent to the size of the Americas,
- nearly a quarter of freshwater resources are lost due to rampant food waste, and
- it is the single largest driver of biodiversity loss.

A circular food system must address the whole value chain, from production to consumption to waste management. The four key solutions for the food system are:
- Put healthier, satiating foods first: Prioritise satiating and healthy foods with a lower environmental impact—ideally shifting calories from meat, fish, and dairy towards cereals, fruits, vegetables, and nuts.
- Go local, seasonal, and organic: Prioritise the production and consumption of local, seasonal, and organic produce (sometimes in combination with GMO to reduce pests and disease loss on crops), which can lead to a significantly reduced need for chemical inputs, fuels, and processing services that contribute to environmental impacts.
- Mainstream regenerative agriculture: Scale up agricultural practices that regenerate ecosystems, recirculate nutrients and sequester carbon by design. 
- End avoidable food waste: Minimise food loss and valorise waste following the food waste hierarchy along the supply chain and at the consumer level through better management of transport and storage, more refrigeration and smart planning, and technology at the consumer and food service levels.



🍏 Food Systems

Manufactured goods, such as vehicles, textiles, appliances and equipment and their associated production processes are big employers but:
- production processes often rely on fossil fuels and currently drive one-third of the overshoot on the climate change planetary boundary due to its GHG production, 
- material- and energy-intensive industrial activities are linked to deforestation and drive 15% on both the land use and freshwater planetary boundaries, 
- manufacturing goods results in substantial amounts of hazardous industrial waste and leaks chemicals into the environment.

Here, circular solutions must tackle the full value chain, but material demand must also shrink: this will necessitate a societal shift to favouring sufficiency over excess and reducing consumption to sustainable levels. Our four key solutions for manufactured goods are:
- Mainstream industrial symbiosis and efficiency : Achieve process improvements, scrap diversion and reduction in yield losses through greater industrial symbiosis and efficiency. Foster tighter collaboration within and between industries to deliver powerful material and emissions savings.
- Extend the lifetime of machinery, equipment, and goods: Maximise the lifetime of goods that serve our daily needs to bring a number of environmental benefits. 
- Buy what's needed: Reduce the number of purchases of common electronic goods, appliances, and other equipment to sufficiency levels. 
- Eschew fast fashion in favour of sustainable textiles: Drastically reduce new clothing purchases. All used clothing should go on to be repaired, reused or, if needed, recycled appropriately. Prioritise natural and local textile manufacturing, as well as higher-quality and more durable garments.

**Ensure sustainable consumption and production patterns**

The world is seriously off track in its effort to halve per-capita food waste and losses by 2030.The COVID-19 pandemic has had significant impacts on consumption and production patterns, with disruptions to global supply chains and changes in consumer behaviour. 

Responsible consumption and production must be an integral part of the recovery from the pandemic. 
But the global economy also needs to speed up the decoupling of economic growth from resource use by maximizing the socio-economic benefits of resources while minimizing their negative impacts. 

Reporting on corporate sustainability has tripled since the beginning of the SDG period, but the private sector will need to significantly improve reporting on activities that contribute to the SDGs. 

This primarily entails environmentally sound management of "toxic chemicals" A substantial use of chemicals is essential to meet the social and economic goals of the world community, and these can be used with a high degree of safety when best practices are followed.  Gross chemical contamination, with grave damage to human health, genetic structures reproductive outcomes, and the environment, has been continuing within some of the world's most important industrial areas, and restoration will require major investment as well as the development of new techniques.
Effective control of the generation, storage, treatment, recycling and reuse, transport, recovery and disposal of hazardous wastes is another similar challenge. 
In addition,  solid wastes include all domestic refuse and non-hazardous wastes such as commercial and institutional wastes, street sweepings construction debris, and, in some countries, human wastes. As hazardous waste is frequently intermixed with other waste, this poses particular management challenges.
Finally, this target ensures that radioactive waste is safely managed, transported, stored and disposed of, with a view to protecting human health and the environment. 

To deliver SDG12, it is crucial to implement policies that support the shift to sustainable practices and decouple economic growth from resource use.

Ensure sustainable consumption and production patterns

**Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss**

The world is facing a triple planetary crisis of climate change, pollution and biodiversity loss. The trend in forest loss, land degradation and the extinction of species is becoming worse, posing a severe threat to the health of the planet and people. Goal 15 will not be met without a dramatic shift in our relationship with our natural environment.

Forests have a significant role in reducing the risk of natural disasters, including floods, droughts, landslides and other extreme events. At the global level, forests mitigate climate change through carbon sequestration, contribute to the balance of oxygen, carbon dioxide and humidity in the air and protect watersheds, which supply 75% of freshwater worldwide. Mountains are also among the ecosystems to be conserved, restored, and sustainably used.

Similarly, deserts are being addressed as 'fragile ecosystems'. Desertification affects as much as one-sixth of the world's population, 70 percent of all drylands, and one-quarter of the total land area of the world. It could result, among others, in widespread poverty as well as in the degradation of billion hectares of rangeland and cropland.

Based on extensive interviews and desk research, this Report aims to show governments and industry leaders that if they want to turn theory into action and scale an economy that delivers on needs within the safe limits of the planet, they need to dismantle harmful entrenched processes and align enabling elements - policy, finance, and people 

- Create a level of policy playing field: Set the ‘rules of the game’ through policies and legal frameworks that incentivise sustainable and circular practices while penalising harmful ones, thereby shaping the nature and scale of economic activities across industries and nations. 



Policy

Slow strategies aim to keep materials in use for as long as possible, for example through design for durability and repairability. A more circular economy is also a slower one: materials, components, and products—and even buildings and infrastructure—that we lock in stocks are made to last. This will lower material demand in the long run, in essence also serving to narrow resource flows.

Slow

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).
