In the processes of urban regeneration, in a circular transition perspective, a multiscalar, integrated and systemic approach allows intervention scenarios to be defined, based on a renewed conception of environmental-economic-social sustainability characterised by circular flows of material and non-material resources. Research results translate these demands into a methodological model at the district scale, trialled in two public housing neighbourhoods in Rome, to turn them into “circular districts”. It is demonstrated that, by applying a circular model of ecological transition to urban districts, the 2050 goal of climate neutrality may be attained, while at the same time improving ecosystemic quality, environmental performance and bioclimatic adaptivity in a wide vision of green cities.

The integration of sustainable development concepts with the traditional supply chain improves the environmental performance and green image among its stakeholders. During adoption of sustainability concepts in traditional supply chain management, some hurdles can be anticipated. These hurdles are called barriers, and industries must equip themselves to remove them. The difficulties associated with removal of barriers are identification and analysis for selection significant barriers. In this chapter, the significant barriers for incorporating sustainability in supply chain of high volume manufacturing are consolidated from the literature and categorized into seven groups: people, strategic, environmental, economic, societal, regulatory, and functional. The widely used evaluation methods are interpretive structural modeling and DEMATEL for which the procedure and guidance to infer the results are detailed. The chapter is expected to support the practicing engineers involved in implementation of sustainable concepts in supply chain.

Sustainable development and globalization are becoming important subjects for policy makers to formulate the worldwide strategies and rubrics for ensuring simultaneous adoption of its components and monitoring of its consequences. Sustainable Development Goals (SDGs) published by United Nations are the guidelines to incorporate the assurance of sustainable development and its globalization. This study analyzes the sustainability from the perspective of not just the environment and the ecosystem of globe but also from the health and social aspects of humans. Indexes such as Environmental Performance Index (EPI) and Social progress Imperative (SPI) measure the performance of different countries based on the environment and the ecosystem by following Millennium Development Goals (MDGs) and social goals, separately. However, the parameters used in those indices have significant limitations. In this work, the proposed Environmental and Social Sustainability Index (ESSI) offers a new model whereby new relevant sustainability parameters including social progress indicators are used to measure the performance of countries based on SDGs by using reliable data from international organizations. Finally, countries are categorized according to sustainable development goals that highlight the importance and significance of each sustainability parameter especially for developing and under developed nations.

One of the main threats to ecological safety is the increased emissions of greenhouse gases. Promoting the purchase of electric vehicles and increasing their share among all cars in a given country can be considered as activities reducing the emissions of CO2 into the atmosphere. Based on Environmental Performance Index, in 2021, Poland is in 37th place among the most climate-friendly countries in the world, and 30th among similar countries in Europe. The aim of the article was to model the prices of electric vehicles as one of the elements of promoting climate security in Poland. For the purposes of the study, an analysis of data from electric vehicle sales advertisements on one of the Polish automotive services was carried out. Moreover, on this basis, the most important factors influencing the price of the vehicle were analyzed. For this purpose, forecasting models were built based on neural networks and selected models of decision trees based on the CART algorithm, boosted trees, and random forest. We assessed the developed models and compared their prognostic abilities.

Abstract As a global concern, the sustainability of a product is the responsibility for manufacturing. Product design has become one of the sources and core drivers for manufacturing competition, and the international competitiveness of products would mostly depend on product design capabilities. The product design has essential and profound impacts on the manufacturing, and thus, many researchers focus on product design and make varies of contributions in this area. Product sustainable design is a design process for a product with the consideration of environmental, economic, and social sustainability during the product entire life cycle. The result of product sustainable design is the creation of products with high sustainability of environmental, economic, and social aspects. This paper reviews the state of the art in the product sustainable design methodologies and tools from the perspective of environmental, economic, and social aspects. For the environmental perspective, design for environment methodologies and tools would enable products in a more environmentally friendly manner in the manufacturing. For the economic perspective, this paper introduces the design methodologies for the economic sustainability with cost, assembly, manufacture, and supply chain. For the social perspective, this paper introduces sustainable social design and social responsibility design for social sustainability and social sustainability through social intervention and social innovation. In addition, it encourages future works.

Maritime transport is responsible for 13% of the Greenhouse Gases (GHG) emissions of the transport sector. Port authorities, terminals, shipping companies, and other stakeholders have joined efforts to improve this sector’s environmental performance. In Spain, the Ministry for Ecological Transition and Demographic Challenge has developed a methodology to assess the carbon footprint. This methodology has been adapted to ports and applied to processes under the Port Authority of Valencia’s umbrella achieving scopes 1, 2, and 3. The results highlight that ship traffic, within the port, of containers and cruises (categorized in scope 3) had a major impact on the carbon footprint. Buildings lighting managed by the terminals has a significant effect on scope 2. Diesel consumption shares with gasoline consumption the primary representation in scope 1. The carbon footprint between 2008 and 2016 was maintained, although traffic in the port increased by 24% during this period. The results show a decrease of 17% when emissions are compared using the base year’s emissions factors to avoid external factors. Future projects that include self-consumption or renewable energy policies seem to be the next step in a port that shows good results but still has room for improvement in activities of scope 3.
