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>

Includes measures that protect and enhance ecosystems and biodiversity both within and beyond city boundaries, as well as actions to restore degraded ecosystems.


Protect and restore local ecosystems

Prioritize solutions that use the power of functioning ecosystems as infrastructure to provide natural services to benefit society and the environment; consider nature-based replacements for grey infrastructure.

Promote solutions inspired and supported by nature

The built environment, including housing, commercial buildings, and the necessary infrastructure for mobility, is essential for our livelihoods, but:
- the extraction of minerals used to produce construction materials is responsible for a quarter of global land use change,
- approximately 40% of global GHG emissions can be attributed to buildings’ construction, use and demolition, and
- construction and demolition processes drive nearly one-third of all material consumption. 

Making the built environment more circular must prioritise a heavy reduction in material use—while also closing the loop on materials and bringing secondary and renewable material choices to the fore. Our four key solutions for the built environment are:
- Make the most of what already exists: Make the most of existing materials by reusing, repurposing, upgrading and renovating following circular approaches. Where new builds are needed, use secondary materials and be as efficient as possible with urban planning solutions that follow circular design principles so that buildings can be reused, repurposed, and easily disassembled in the future.
- Be as energy efficient as possible: From the design phase, utilise circular strategies to create material- and energy efficient buildings. Couple these designs with a rollout of clean energy solutions, and prioritise energy-efficient appliances and retrofitting. 
- Utilise secondary materials: Maximise the high-value reuse of buildings and components where possible. Ideally, enable the utilisation of construction and demolition outputs and ensure that as much of it as possible is recycled to avoid the need for virgin materials, such as sand and gravel.
- Prioritise circular materials and approaches: Transition to using renewable wood, timber or cross-laminated timber instead of steel and concrete, or move to other locally available materials. Utilise mainstream modular construction and prioritise lightweight frames and structures to reduce cement and steel use, as well as green roofs where possible.

Water system refers to the water supply network for storing and supplying water for use by the community.

One of the greatest challenges of a city is to provide its inhabitants with safe, clean water from a limited fresh water supply. Improving the city’s water infrastructure efficiency, such as minimising leakages, reduces the strain put on the limited supply, which in turn, helps to ensure inhabitants gain access to clean and affordable water.

The water infrastructure of a city typically consists of components such as surface water diversions, wells, pumps, transmission pipes and canals, treatment and storage facilities, and distribution network elements (Burian et al.). Options for improving the efficiency of the system include investing in water loss reduction systems, creating and following a regular maintenance program, and better matching water supply and demand (Global Water Partnership).

Cities can improve the efficiency of their water system infrastructure by conducting a water audit, in which all water flows are traced and losses in the system are identified to map where the most efficiency improvements can be gained. Alongside this, asset management can be used to create a short-term and long-term strategy of investing in new equipment, refurbishing existing equipment and developing maintenance programmes to ensure infrastructure is as efficient as possible, and leaks are minimised. Such management programmes create financial transparency amongst all stakeholders and provide useful long-term planning for larger infrastructure changes (US EPA)

💧 Water Systems

Cities worldwide are facing significant water-related challenges, including urban water runoffs, flooding, reduced water quality and severe water scarcity—exacerbated by rapid urbanisation and more frequent extreme weather events. On top of this, urban water runoff continues to be a major cause of water pollution in urban areas, carrying trash, bacteria, and other pollutants through gutters and stormwater systems into local waterways, typically without treatment.

City governments can pursue a “sponge city” approach by redesigning the urban fabric and integrating blue and green infrastructure (BGI) (e.g. rain gardens, permeable pavements, storage ponds, etc.) along traditional grey infrastructure (e.g. pipe networks, storage tanks, flood walls). This can help to absorb, store, filter and purify these water flows, in turn replenishing aquifers, reducing the need for expanding grey water management and minimising flood risk, while also reducing the heat island effect. 

Cities can do so by, for example, integrating requirements for BGI into municipal urban planning rules for newly built up areas of city districts, industrial parks and development zones, and integrating sponge city building requirements into municipal urban planning rules. Then, local governments could also strengthen collaboration between all relevant stakeholders—from real estate developers to engineers, to water-utility organisations—to identify locally relevant opportunities for sponge cities.

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...

Based on the work of [Bocken et al. (2016)](https://www.researchgate.net/publication/309699661_Product_design_and_business_model_strategies_for_a_circular_economy), the Four Flows Framework serves as a simple framework for managing resource flows in a circular economy by using less (Narrow), using for longer (Slow), using again (Cycle), and using clean, regenerative materials and energy (Regenerate).

These different principles of circular economy can be applied to our socioeconomic metabolism: we can design stocks like buildings, infrastructure, machinery, and vehicles to be rich resource mines for the future, and design manufactured goods and consumables to be cycled and made regenerative. Furthermore, the focus must also centre on getting more value out of fewer materials. Achieving the aims of a circular economy—minimising material use, regenerating the Earth, and preventing material losses—can be done through these four key strategies mentioned above.

The City of Belgrade developed a Climate Change Adaptation Action Plan and Vulnerability Assessment within the regional project “Climate Change Adaptation in the Western Balkans” implemented by the German International Cooperation Agency (GIZ).The vulnerability assessment analyses extreme weather events in the past and assesses the current vulnerability to extreme weather events in Belgrade. Future risks and opportunities are based on climate data for the city of Belgrade in the present time period and on climate projections as well as on the results of the vulnerability assessment for the city of Belgrade.The action plan includes a list of measures and activities that will be undertaken to adapt to climate change, including responsibilities, time frame, i.e. description of short–term measures and activities (until 2017); medium–term measures and activities (until 2020); long–term measures and activities (until 2025) and prioritization of measures. Climate measures of the Action Plan include green infrastructure, green open spaces, green alleys, green roofs, flood protection, water retentions, water saving and reuse, water drainage, extension of water supply services, rain water storage, urban planning to avoid flood risk, Belgrade Climate Atlas, urban setting, urban texture, heat adapted design, flood adapted design, awareness raising and behavior change. The purpose of monitoring the implementation of the Climate Change Adaptation Action Plan is to understand whether the project or activities deliver the planned benefits and to adjust the measures and activities to potentially changing conditions and new knowledge.

The main objective of the local waste management plan is to minimise waste impact on the environment and to increase the efficiency of resources use, for instance, by establishing a waste management system that includes control of waste generation and use and incentives for investment. The long-term objective of the local waste management plan is to establish a system of non- hazardous waste management that provides the lowest risks and dangers to the environment and conditions for preventing waste generation and ensuring re-use and waste recycling, as well as raising awareness of waste management. The Plan seeks to (1) expand and strengthen administrative capacities in the field of waste management; (2) improve the waste collection system and enlarge the total scope of municipal waste collection to 100% by 2019; (3) establish the system of selective collection, re-use and recycling of waste; (4) build a Waste Management Centre, while also closing and remediating existing dumpsites; and (5) build an animal waste treatment facility. The Plan seeks to (1) build a municipal waste treatment facility, which includes a feasibility study on mechanical-biological treatment and the construction of a cogeneration facility that uses fuel from waste; (2) build a green waste composting facility, which includes a feasibility study and technical documentation; (3) build a construction waste recycling facility, and (4) build a facility for fuel gas production from biomass. The plan includes raising awareness about proper waste handling, separate collection of hazardous waste and home composting in single-family households.
