This study aims to investigate to what extent the construction and demolition waste generated by households is managed by the principles of circularity and to identify the main influencing factors in the behavior of households regarding the circularity-based management of construction waste in Latvia. The current research presents principles of circularity of household-generated waste based on a systematic literature review, and the data obtained from a survey were analyzed using both descriptive and inferential statistics. This study clarifies the circular economy rationale for construction and demolition waste (CDW) management in Latvia and proposes further development to promote the achievement of sustainable development goals and increased energy efficiency. The results reveal that the observance of circular economy principles in construction and demolition waste management among Latvian households does not correspond to good circular economy practices due to attitudes toward environmental issues, expenses, and logistics; thus, compliance with these principles and legislation as well as closer cooperation between municipalities and households can promote significant economic benefits.

Nowadays, European countries, while implementing the goals of sustainable development, are trying to be energy secure by reducing energy consumption and switching to renewable energy sources; the issue of green bonds is essential in the financing of these projects. This study aims to investigate the current situation and trends in green finance, identifies its problems and challenges, as well as determines the importance of green bonds in sustainability in general and renewable energy supply in particular. The authors conducted a bibliometric analysis of green finance and renewable energy, followed by an extensive literature review identifying the benefits and challenges of green bond investments, continued with an empirical study that included hypothesis testing and the creation and analysis of the EU countries clusters, which have not been sufficiently studied to date. A study examining trends in green finance, identifying its benefits and challenges, found that green bond investments have a positive impact on carbon reduction and renewable energy supply in the EU OECD countries, and cluster analysis of the European OECD countries indicated a positive relationship between economic performance and overall ESG risk.

In order to create a sustainable future for the urban environment in s=Smart cities, it is necessary to develop a concept of urban transport, partially reduce the use of traditional transport, primarily cars, as well as the environmental pressure on society, which is essential to move to a sustainable urban future. In the latest discussions on the future of the urban transport system, the quality of the environment, and the possibility of its improvement are discussed, this issue became especially relevant with the onset of the pandemic, when the lockdowns were introduced. The problem of sustainable transport in urban areas has been recognized in academic studies, searching for appropriate models and solutions. The article presents the latest literature review and illustrates the newest trends with several examples. VOS Viewer software has been used to classify the different keywords, according to their co-citation, following clustering techniques. By analyzing the research conducted by other researchers, it has been possible to structure the ecosystem and trends in the Urban Transportation Concept, also mentioning likely future trends. Based on the literature analysis of the Sustainable Urban Transport, the authors of the study found that a large group of researchers deal with technical solutions and innovative business models, while the essential behavioral aspects are examined in less detail. Extensive literature analysis allowed the authors to select several solutions to achieve the transformation towards sustainable transportation in urban areas: new vehicle technologies and their environmental factors' analysis, geographic information systems, the analytic hierarchy process method, the time series analysis of road traffic accidents using multiplicative models, electrification and use of Friedman Analysis of Variance by Ranks, as well as innovations in sharing mobility.

The COVID-19 pandemic has been one of the most unprecedented crises of recent decades with a global effect on society and the economy. It has triggered changes in the behavior and consumption patterns of both final consumer and industrial consumers. The consumption patterns of industrial consumers are also influenced by changes in consumer values, environmental regulations, and technological developments. One of the technological highlights of the last decade is biocomposite materials being increasingly used by the packaging industry. The pandemic has highlighted the problems and challenges of the development of biocomposites to adapt to new market conditions. This study aims to investigate the industrial consumption of biocomposite materials and the influence of the COVID-19 pandemic on the main stages of the value chain of sustainable industrial consumption of biocomposites. The research results reveal there is a growing interest in the use of biocomposites. Suppliers and processors of raw materials are being encouraged to optimize and adapt cleaner production processes in the sustainable transition pathway. The study highlights the positive impact of COVID-19 on the feedstock production, raw material processing, and packaging manufacturing stages of the value chain as well as the neutral impact on the product manufacturing stage and negative impact on the retail stage. The companies willing to move toward the sustainable industrial chain have to incorporate economic, environmental, social, stakeholder, volunteer, resilience, and long-term directions within their strategies.
