However, in Russia, most often circular economy means recycling system. The principles of circular economy are aimed at the economic, social, and environmental well-being of people. Experts identify factors that promote and hinder the development of circular economy in Russia. Issues of sustainable development, circular economy and energy transition are actively discussed by representatives of government, business and science at international and all-Russian forums. The principles of circular economy will allow achieving several Sustainable Development Goals. The circular economy is one of the key factors in achieving carbon-free energy goals.
