The Ellen MacArthur Foundation develops and promotes the idea of a circular economy. It works with, and inspires, business, academia, policymakers, and institutions to mobilise systems solutions at scale, globally.

Its vision is a new economic system that delivers better outcomes for people and the environment. Business models, products, and materials are designed to increase use and reuse, replicating the balance of the natural world, where nothing becomes waste and everything has value.

A circular economy, increasingly built on renewable energy and materials, is distributed, diverse, and inclusive. The Foundation’s work focuses on six interlinking areas:

1. Learning
2. Business
3. Institutions, Governments and Cities
4. Insight and Analysis
5. Systemic Initiatives
6. Communications.

Turuta is a project of mutual exchange and enrichment. Starting in 2010 as an experimental project of a new microeconomy, it gave birth to the "turuta market", based on a social currency called turuta (a traditional military march played during Carnival parades). This is used to pay for local goods and services, promoting local production and interchange. Each partner in the turuta market has an online account.

It is a living project being developed by the members of the association ECOL3VNG (local ecological economic ecosystem at Vilanova i la Geltrú, Barcelona). The collective history of this ecosystem is being written through minute-taking (agreements of Board, commissions and assemblies, i.e. the "legislation") and account-taking of the exchanges between partners.

ReThink is a platform aiming at promoting sustainable and circular economy in Ukraine, through education and advocacy campaigns, multi-stakeholder dialogue and innovation facilitation.

A prominent activity for the platform in 2019 focused on single-use plastic bags, with a call to the Ukrainian government to tackle the issue, and partnering with law firms for the drafting of a law proposal to restrict the use of plastic shopping bags and plastic packaging in Ukrainian retail stores.

Circular Norway is Norway's first and only politically independent, independent member organisation that works nationally to transform a linear to a circular economy. On behalf of its members, the association works politically to strengthen framework conditions and increase the pace of change.

Circular Norway helps its members to make better use of their resources and strengthens their competitiveness in the national and international market. Through practical help, expertise and knowledge networks, it makes the transition to a circular economy both easier and more profitable.

The network published the first comprehensive report on Norway and Circular Economy in April 2019, and has also begun producing visual guides to explain the principles of circular economy for a Norwegian audience. Circular Norway was instrumental in bringing the concept to the forefront of political discussion by hosting a session on circular economy at the August 2019 'arendulska political festival'.

Catalunya Circular was launched on the 9^th of May 2018 in Barcelona and it already has around 20 member organizations. Its aim is to become a central point of reference for circular economy (CE) in Catalonia.

Besides providing useful knowledge and information on CE, Catalunya Circular offers an opportunity to raise awareness about the work done by Catalan businesses and society by publishing details of their CE initiatives. These initiatives are geolocated on an interactive map and can be selected using a search engine that allows users to look for projects by keyword and/or type of economy.
