Electric vehicles offer the promise of major reductions in local CO2, NOX and particulate emissions. In addition, electric vehicles are silent, easy to service and have high 'well-to-wheel' energy efficiency. However, the introduction of electric vehicles into society also poses several important challenges. Current electric vehicle technologies have limitations with respect to ease of use, driving range, and time-to-charge, and are relatively expensive. Moreover, the use of electric vehicles requires an adequate charging and electric grid infrastructure, as well as dedicated solutions for vehicle charging and storage that are optimally integrated into the built environment.

In general, the literature on sustainability has focused mainly on the environmental issues, whereas, more recently, a Circular Economy has been proposed as one of the latest concepts for addressing both the environmental and socio-economic issues. A Circular Economy aims at transforming waste into resources and on bridging production and consumption activities; however, there is still limited research focusing on these aspects. This paper addresses the link between procurement and supply practices, and proposes changing from a traditional public procurement process, based on product-selling business models, to a more serviceoriented system. The paper proposes a framework to include technical and non-technical specifications of product/service combinations that improve resource usage efficiency through recovery. The framework also considers socio-cultural specifications and physical and social proximity between the stakeholders in the procurement process. The framework is based on collaboration, which is a vital link between the public procurement process and the development of more sustainable business models, where the experience gained in the collaboration process serves as the bases for suppliers and procurers in improving their contribution to CE, whilst at the same time securing economic benefits for both parties. Although, in this process, the specification setting may take longer, the relationships between procurer and supplier tend to be longer lasting and stronger. This research shows that collaboration between procurers and suppliers throughout the procurement process can lead to reductions in raw material utilisation and waste generation, whilst promoting the development of new, more sustainable, business models.

Drawing on interviews with food waste specialists, this study construes the boundaries between food surplus and food waste, avoidable and unavoidable food waste, and between waste prevention and waste management. This study suggests that the first step towards a more sustainable resolution of the food waste issue is to adopt a sustainable production and consumption approach and tackle food surplus and waste throughout the global food supply chain. The authors examine the factors that give rise to food waste throughout the food supply chain, and propose a framework to identify and prioritize the most appropriate options for prevention and management of food waste. The proposed framework interprets and applies the waste hierarchy in the context of food waste. It considers the three dimensions of sustainability (environmental, economic, and social), offering a more holistic approach in addressing food waste. Additionally, it considers the materiality and temporality of food. The food waste hierarchy posits that prevention, through minimization of food surplus and avoidable food waste, is the most attractive option. The second most attractive option involves the distribution of food surplus to groups affected by food poverty, followed by the option of converting food waste to animal feed. Although the proposed food waste hierarchy requires a fundamental re-think of the current practices and systems in place, it has the potential to deliver substantial environmental, social and economic benefits.

The magnitude and complexity of the global food waste problem has brought it to the forefront of the environmental agenda; however, there has been little research on the patterns and drivers of food waste generation, especially outside the household. This is partially due to weaknesses in the methodological approaches used to understand such a complex problem. This paper proposes a novel conceptual framework to identify and explain the patterns and drivers of food waste generation in the hospitality sector, with the aim of identifying food waste prevention measures. This conceptual framework integrates data collection and analysis methods from ethnography and grounded theory, complemented with concepts and tools from industrial ecology for the analysis of quantitative data. A case study of food waste generation at a hotel restaurant in Malaysia is used as an example to illustrate how this conceptual framework can be applied. The conceptual framework links the biophysical and economic flows of food provisioning and waste generation, with the social and cultural practices associated with food preparation and consumption. The case study demonstrates that food waste is intrinsically linked to the way we provision and consume food, the material and socio-cultural context of food consumption and food waste generation. Food provisioning, food consumption and food waste generation should be studied together in order to fully understand how, where and most importantly why food waste is generated. This understanding will then enable to draw detailed, case specific food waste prevention plans addressing the material and socio-economic aspects of food waste generation.

This special volume stream is comprised of 33 papers that illustrate some of the efforts being taken by higher education institutions to contribute to sustainability. The majority of the papers were presented at the European Roundtable on Sustainable Consumption and Production - Environmental Management for Sustainable Universities conference in Istanbul, Turkey in 2013. The papers address topics such as implementation of sustainable development, stakeholder engagement and participation, campus operations, sustainability reporting and assessment, organisational change management, and curriculum development. the papers in this special volume stream provide significant steps for the higher education for sustainable development discipline by exploring new and rethink theories, approaches, concepts, methods, and frameworks, as well as providing case studies and guidelines for practitioners. As the collection of papers shows, there have been many efforts in the implementation of sustainable development in higher education institutions; however, there are still many challenges to integrate sustainable development into their systems, and many opportunities for research in the topic.

Nonetheless, corporations are also perceived as possessing the resources, technology, global reach, marketing skills, and, sometimes, the motivation to work towards more sustainable societies, as well as changing customers’ behaviours to make them more consistent with sustainability principles. Corporate leaders and employees have been recognising the relations and inter-dependences of the economic, environmental and social dimensions, for satisfying the needs of today’s societies without compromising the needs of tomorrow’s societies, i.e. sustainability. Seaports are an important player in the corporate world, due to their role in global production and distributions systems, by trading over six and a half billion metric tons annually.

Many port cities, or seaports, provide a historic hub of urban development with cities having grown up around them. They often have a very specific heritage with a strong sense of place and community, and they provide jobs and economic prosperity to those communities. However, technological change such as increasing ship size, and also the growth of competition from mega-ports, are factors that have contributed to the decline of both historical and more modern port areas. This presentation considers some of the pressures on ports that mean they need to change. It identifies that there has been a move away from waterfront redevelopments where new apartments and offices have replaced commercial port areas, to redevelopments that seek a more sustainable way of redeveloping – both for the port and its local community and area.

This paper presents the process undertaken to prepare the first draft of the University of Leeds sustainability report. The objective of the exercise was to provide a base and complement other sustainability initiatives taken at the University of Leeds. The process of developing the report was done in three stages: (1) collecting data; (2) populating the indicators; and (3) assessing the performance values from the information collected using the Graphical Assessment of Sustainability in Universities (GASU) tool. Although there were limited time and resources for the process, the results in indicator coverage and performance were higher than other the analysis of other HEIs that have published Global Reporting Initiative based reports. When preparing a sustainability report it is important to have a holistic perspective, addressing the different inter-relations between indicators, categories, and dimensions, as well as stakeholders throughout the university system.
