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>

Food and Beverage

Utilise bio-based, reusable, non-toxic and non-critical materials

Regenerative materials

Engage with the local community where facilities or offices are located

Community collaboration

Develop regenerative infrastructure

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.

Governments

Biodiversity is fundamental to maintain the variety of crops and livestock needed to support and preserve ecosystem services that sustain our food system and wellbeing. As cities densify and expand in size, they typically encroach on surrounding biodiverse areas, leading to the progressive degradation of ecosystem services. In turn, this pushes away urban food systems that are dependent on material inputs often sourced outside the urban region. 

Edible green infrastructures are solutions that reimagine cities as productive sources of food, can boost local biodiversity as well as foster social cohesion. These infrastructures can take a variety of forms and are inspired by nature, for example, planting edible trees and plants throughout a city which are free to pick for residents.

Local governments can promote investments in edible green infrastructures (strategically planned multi-scale networks of different kinds of urban green and blue spaces) to create new biodiverse and productive spaces within the urban region, as well as rehabilitating polluted lands to improve soil health and productivity. Urban and spatial planning can also be used to permit these infrastructures, as well as enable residents to create their own. What is more, such solutions can be integrated within urban planning projects, for example, rain gardens and rain barrels, to reduce urban stormwater runoff and risk of floodings while redirecting and reusing urban rain and stormwater to supply urban farmers.

A framework of policy instruments that enable and stimulate the transition to the circular economy

The principles of a circular economy concern designing out waste, regenerating ecosystems and keeping items in use. Decoupling the economy from material flows—improving the rate of resource productivity faster than the economic growth rate—is also a consistent guide. By evolving with the growing number of applications of circular economy principles, and consolidating these strategies across thematic areas, Circle Economy’s Key Elements Framework (KE) renders the elements of the circular economy salient and serves as a basis to derive contextual strategies and interventions. 


The Framework consists of:
- Core Elements: Activities directly handling product or material flows; and uniquely,
- Enabling Elements: those that remove obstacles for core actors.

Circle Economy's framework of strategies and activities that define the circular economy

The Circular City Actions Framework provides urban changemakers with five complementary strategies they can use to start working towards a more circular system. 

The framework is action-based to provide users with concrete strategic directions and showcase the desired outcomes of each strategy. 
The framework consists of five complementary **strategies**, under which **sub-strategies** provide further detail. Finally, each sub-strategy consists of a diversity of tangible **solutions** which are framed in relation to key thematic areas. 

Note: solutions are currently focused on:
- 🍏 **Food systems**
- 🏢  **Built environment**
- 👕📱  **Consumer goods**
- ⚡ **Energy Systems**
- 🚌 **Mobility Systems**
- 💧 **Water Systems**

More thematic areas are coming soon...

This framework was developed in collaboration with ICLEI, Metabolic and Ellen MacArthur Foundation with support from the MAVA Foundation. Read more about it [here]( https://circulars.iclei.org/action-framework/).
