The optimization of municipal solid waste management requires the re-organization of niche sectors too. The sector of the university is not fully explored from the scientific point of view. The creation of networks among universities in order to face this issue allows an exchange of expertise also at an international level as demonstrated in this article, by three case studies: two Italian (University of Trento and University of Insubria) and one Russian (Ural Federal University) universities. This study highlights the pros and cons of each university in terms of waste management. Specifically, setting up communication campaigns, standard procedures, monitoring actions, pricing strategies that incentivize selective collection, and improving the collaboration within the university community are identified as crucial initiatives. The margins of improvement of the three universities analyzed are favored by the composition of the generated waste. The implementation of good practices can give economic advantages to the universities, besides improving their level of sustainability.

The implementation of investment projects has an important role to play in the development of the economy and also to be in concordance with the Circular Economy concepts, as it causes not only the flows of financial and labor resources into the regional economy, but also stimulates the development of scientific and technological progress and the emergence of innovations. A comprehensive assessment is essential approach of any investment project to achieve sustainable development and to close the loop as requested be the Circular Economy through balancing between social and economic development, as well as preservation of environment. The assessment of ecological and economic efficiency of investment projects is one of the most significant stages of project implementation as it allows to uncover the potential negative effects and possible failure of the project. So far, there are no unified approaches to assessing the effectiveness of investment projects, especially its environmental component. That fact leads to a biased assessment of the impact of an investment project on the environment. The problem is caused not only by the lack of a common, internationally accepted methodology, but also by the complexity of accounting for externalities and negative financial impact. The purpose of the study is to examine and systemize existing approaches to the assessment of ecological and economic efficiency and provide recommendations for its enhancement. The article highlights two conceptual approaches to the efficiency assessment of the project and their benefits and drawbacks.

Sustainable development is a key principle of national and international policies, which has been strongly promoted by the European Union since 2015. Communication, education, the awareness of the importance of accelerating the transition from a linear economy to a circular one and of raising environmental awareness play a key role in the achievement of sustainable development goals (SDGs). To achieve the goals on a large scale, it is necessary to start from a local scale. In this sense, universities must experiment best practices and make them available to the society. In the last years, many universities have adopted environmental sustainability plans in order to implement green policies and develop a roadmap towards the achievement of the SDGs, while sharing best practices with university communities and society. This paper presents the case of two Italian universities and a Russian one. Specifically, the paper presents the contents of the current environmental sustainability plans of the Italian universities, discussing the reasons for the choice of the environmental sustainability goals and the expected results following the implementation of the related actions. A comparison between the approaches adopted in the sustainability plans of the two Italian universities will be presented in details. In addition, the paper analyses the potential implementation of a sustainability plan in the Russian university. The paper will discuss also potential criticalities in the achievement of the goals.

The activity of the world community in the field of climate and environmental conservation is increasing every year. The Paris Agreement, signed in 2015 by the majority of governments, and the additional goals set on COP26 in 2021 set the objectives of maximum reduction of greenhouse gas emissions into the atmosphere and the transition to renewable energy sources (RES). Consequently, the energy sector, as the largest sector of the world economy and the largest environmental polluter, is undergoing the greatest change. The development and implementation of an effective policy in the field of RES, which is part of the energy development strategy, is one of the factors of renewable energy market's rapid development and stimulating the transition to clean energy. However, despite the measures taken by the world community to reduce the environmental impact of the energy sector and the development of renewable energy, the volume of greenhouse gas emissions continues to show an upward trend: from 2000 to 2021, the volume of CO2 emissions produced by the power sector increased by 74.7%. This trend might be associated with a low level of elaboration of the current renewable energy policy, with barriers to the development of the renewable energy market or with the specifics of the energy sector. The purpose of this study is to review and analyze renewable energy policies in the European Union, Russia, and the United States in order to identify specific approaches to the development of renewable energy, key tools, and barriers. The current state of the energy sectors of the considered countries was analyzed, their features were identified, and a review as well as a comparative analysis of their renewable energy policies were conducted.

In view of the current agenda in the field of climate and environmental conservation, the requirements for environmental project appraisal are being tightened: the evaluation of environmental indicators of project implementation should be carried out on a par with indicators of its economic performance. Current approaches to the assessment of environmental and economic efficiency do not completely cover the negative environmental impacts of a project’s implementation, and this reduces the effectiveness of the evaluation. Therefore, it is necessary to develop a system of environmental indicators that will address the specifics of the industry. This is made possible on the basis of determining a list of key factors that should be included in the evaluation system. The purpose of this study is to determine the most significant factors for establishing a simple yet thorough assessment framework to evaluate the efficiency of energy investment projects. Research methodology includes an a priori ranking method and analysis of interrelations between factors. Based on the results obtained, the authors have formed a list of key factors that could become the basis of a future system of environmental indicators for the efficiency assessment of energy projects.

According to the annual world statistics, primary energy consumption demonstrated a steady growth over the past decade but in 2018, its average value was doubled. A rapid development of energy sector will not only lead to the growth of CO2 emissions and other negative consequences, but also to more intensive use of natural resources in the immediate future. Growing pressure on resources might give rise to a number of challenges in virtually all branches of human activity. The energy sector's impact on the environment is increasing at a high speed, which necessitates the efficiency assessment of investments in energy projects applying a system of technical, economic and environmental indicators. Nowadays, most of the energy projects comprise eco-friendly technological solutions that significantly decrease the use of natural resources but at the same time they might affect financial costs that dampen the attractiveness of investment projects at all. Despite that fact, the economic and environmental evaluation allows identifying the total exposure of the project in the long term and aids in measuring its multiplier effect on the region economy as lots of energy projects have a considerable innovative potential. The present study provides a system of environmental indicators that improves the efficiency assessment process of investment projects in the energy sector.

The higher education system makes it possible to accelerate the process of transition of the economy and society to a sustainable direction of its development by forming a new ecological worldview among the younger generation and minimizing future ecological and economic damage to the environment of the region in which the university is located. Nowadays, the pace of the implementation of sustainable development principles in the operational and educational activities of Russian universities remains low, which affects the level of environmental and economic security. The purpose of this study is to identify barriers and prospects for the implementation of sustainable development principles in Russian universities, as a factor of increasing the level of environmental and economic security, using the case of Ural Federal University. The authors analyzed the university's development program, its implemented activities in the field of ecology and sustainable development, its eco-oriented activities, and evaluated the university using the UI Green University Metrics methodology in order to determine its potential position in the green universities ranking. SWOT analysis was carried out to combine the results obtained and to identify the barriers to the implementation of the sustainable development principles and the barriers to increasing the level of environmental and economic security. Promising directions for the development of the university for the coming years were also identified within the framework of the new concept. The main barriers are the lack of an official program of sustainable development of the university, appropriate administrative and economic management tools and targeted state support. In order to stimulate the university's transition to a new concept, the development of a specialized information resource and improvement of the solid municipal waste management system are proposed. A list of economic, organizational and administrative tools for managing sustainable development is also formulated. The implementation of these measures could not only form the foundation for the successful implementation of the sustainable development principles at Ural Federal University but would also increase the university's potential position in the UI Green University Metrics rating and would have a positive impact on the level of environmental and economic security.
