Progressive urban density affects city centers especially and results in growing congestion, lack of parking spaces, and increasing environmental costs of transportation, causing increased air pollutant emissions and noise. These phenomena reduce the attractiveness of the city and result in a degradation of the quality of life for its residents. In light of these phenomena, there is a clear need for intelligent management of urban space using new technologies that would be complementary to existing intelligent transportation systems. Expanding information resources obtained from mobile cameras will have a positive impact on increasing the efficiency of transportation management and use of limited space in city centers. It will also have an impact on reducing external transport costs and increasing the quality of logistics services provided in the city. The main aim of the paper is to develop a concept of a transport management system in cities using mobile vision systems mounted on unmanned aerial vehicles. The model will concern the cases of lane occupation by freight vehicles and the analysis of parking spaces in the city in order to improve their management. The results of the developed model will contribute to the automation of the parking space management process and increase the efficiency of the use of city parking space resources.

Information technology advancements integrated with the e-commerce supply chain allow participants in the business process to effectively work with large volumes of data and control transactions. To improve the profitability and competitiveness of e-commerce companies, a blockchain solution was incorporated into the global B2B (Business-to-Business) supply chain. This technology simplified the transaction process by providing all participants in the sustainable B2B buying process with the same data about the trade. Overall, the use of blockchain improved the efficiency of logistics and digital documentation which reached 74% and 75%, respectively. The main advantage of using blockchain is that it creates a decentralized database that is secure. In addition, it increases the speed of payment and the reliability and transparency of data transfer. Further research may focus on the use of blockchain in green logistics to improve environmental sustainability in the e-commerce supply chain.

The global climate change agenda proceeds at an incremental pace while the Earth is approaching critical tipping points in its development trajectory. Climate action at this pinnacle juncture needs to be greatly accelerated and rooted in the fundamentals of the problem—human beings’ disconnection from nature. This paper underscores the valuable role nature and nature-based solutions can play in addressing climate change at the city scale and its implications for broader sustainability. Urban ecosystems (nature in cities) are seen as an integral part of a proposed local climate action rubric wherein policy measures and integrated planning guide lowcarbon/impact development to create more resilient and sustainable urban environments. The use of green infrastructure is highlighted as a cost-effective means to contribute to mitigation and adaptation needs as well as to promote human wellbeing. The paper takes an exploratory view of the influence of ecosystem services, particularly cultural services, and its economics in relation to the individual and society to understand how biophilia can be nurtured to promote environmental stewardship and climate action.

Nowadays, apart from travel time and cost, more and more attention is paid to ensuring that ecological footprint of the means of transport used for a journey is as small as possible. Therefore, it is reasonable to look for methods and solutions that will allow planning communication connections according to the principles of sustainable development. The aim of the article was to present mathematical model of the proecological distribution of traffic flow into a network, together with a determination of how the amount of emissions of harmful compounds for rail transport will be calculated (based on amount of energy necessary for movement, calculated on circumference of the wheels). The model has been verified on real data. The traffic flow was distributed over a selected communication route: Warszawa—Gdansk, where the criterion was minimization of total carbon dioxide emissions. An evolutionary method implemented in Microsoft Excel was used to solve the optimization problem. For the analysis of only the fastest connections, the railway one was the optimal from the point of view of the adopted criteria. After the train capacity was exceeded, air and car connections were loaded. Based on the research, a function that represents the amount of carbon dioxide emissions in the analyzed traffic route depending on the size of the traffic flow was developed.

The article discusses the issues of individual low-cost and sustainable tourism and its main goal is to confirm that individual low-cost travel is in fact a form of tourism within which the principles of sustainable tourism are implemented. It is a theoretical article based on desk research involving literature analysis. The study has confirmed that individual low-cost tourism and various other types related to it show relevant relationships with the ideas of sustainable development. These affinities are visible concerning economic, sociocultural, and environmentally balanced growth. However, the research results presented in the article are theoretical and need further empirical verification. Therefore, the authors treat this study as a work provoking discussion on the issue of the relationship between individual low-cost and sustainable tourism.

In the framework of this study, significant features of the formation of the strategic potential of the enterprise in a circular economy are identified. The characteristics and elements of the strategic potential of the enterprise, which can ensure its integrity and continuity of operations, are highlighted. The authors conducted and analyzed a theoretical review of the concept of the “circular economy” and its impact on business and resource conservation and environmental protection. The conditions for the transition to a circular economy at the macro level are formed. The key stages of ensuring the strategic potential of the enterprise, taking into account the internal and external environmental factors, are highlighted. The authors forecast the volume and dynamics of waste until 2027 using the Cobb–Douglas function. The mechanism of the formation of the strategic potential of the enterprise in the conditions of a circular economy is offered. This mechanism provides for the potential compliance with the strategic goals of the enterprise, as well as the rationality and balance of structural elements. Assessing the compliance of strategic potential with the developed strategy allows decisions to be made on the implementation of measures to meet the objectives of the enterprise, or to search for opportunities and reserves to improve its level. A set of measures aimed at the effective implementation of the proposed mechanism and the results of resource-efficient production is developed.

The complex and networked nature of sustainable procurement is evoked through confronting two conceptual models, the triple bottom line-inspired parallel-type “interlocking circles model” with the more systems-oriented series-type “concentric circles model”. This endeavor is integrated with a developed application of contingency theory rooted in network thinking. Two subcase narratives from Ghana, one in the upstream portion of the supply chain associated with exploration and platform-based production, and the other an oil refinery in the downstream part are provided. Interaction, interdependency, and integration, all associated with value, conceptually ground the analyses. A developed empirically grounded conceptual model depicts sustainability as systemically intertwined with value and networked in an immediate business, network, and wider noncontextual natural and social environment. Sustainable procurement is networked, a value creating managerial process rather than, as the triple bottom line posits, a norm “out there” directing managerial action. Sustainability is inherently complex. Rather than guiding action through deterministic ethical norms, it emerges as emergent practices primarily through purposeful interaction within the supply network that instead may be interpreted and developed in a long-term sense through using the two discussed conceptual models on sustainable production.
