The article discusses the basic principles of the implementation of the transition from a linear economy to a circular economy model. The article summarizes the existing problems that require solutions to create new jobs, increase economic growth, and create a balance between the economy, environment and population. The authors present examples of building a circular economy model in foreign countries. The importance of the tasks of implementing and promoting the circular economy was revealed, thanks to the involvement of all participants in the society in this process and the motivation for companies and investors. Effective tools for moving society towards a resource-efficient closed-cycle economy, increasing energy efficiency, energy conservation and reducing the energy intensity of the gross domestic product, due to the entry into a competitive level of renewable energy sources are investigated. The introduction of digital technologies and artificial intelligence in automated accounting of resource consumption, as well as the improvement of accounting rules will create opportunities for the end user to manage resource consumption taking into account the principles of a circular economy. The authors' study emphasizes that circular economy products and services should minimize resource use and promote reuse, recovery and recycling of materials in the future, leveraging existing product policy instruments, further support for the repair sector, improved design for reuse, and high-quality packaging recycling. The authors in the article propose to legislate the subsidizing of enterprises participating in the circular chain and subsidizing innovative developments in the field of the circular economy in the Russian Federation.

The circular city is emerging as new concept and form of practice in sustainable urban development. This is a response to the complex and pressing challenges of urbanization, as highlighted in the New Urban Agenda (NUA). The concept of a “circular city” or “circular city-region” derives from the circular economy model applied in the spatial territorial dimension. It can be associated with the concept of a “self-sustainable” regenerative city, as stated in paragraph n.71 of the NUA. This paper aims to develop an extensive form of “screening” of circular economy actions in emerging circular cities, focusing on eight European historic port cities self-defined as “circular”. The analysis is carried out as a review of circular economy actions in the selected cities, and specifically aims to identify the key areas of implementation in which the investments in the circular economy are more oriented, as well as to analyze the spatial implications of the reuse of buildings and sites, proposing a set of criteria and indicators for ex-ante and ex-post evaluations and monitoring of circular cities. Results show that the built environment (including cultural heritage), energy and mobility, waste management, water management, industrial production (including plastics, textiles, and industry 4.0 and circular design), agri-food, and citizens and communities can be adopted as strategic areas of implementation of the circular city model in historic cities, highlighting a lack of indicators in some sectors and identifying a possible framework for “closed” urban metabolism evaluation from a life-cycle perspective, focusing on evaluation criteria and indicators in the (historic) built environment.
