This paper describes the research that underpins the development of EATS (the Environmental Assessment Tool for School meals), a life cycle-based decision support tool for local authorities and their contractors responsible for providing catering services to schools. The purpose of this tool is to quantify the carbon footprint (CF) and water footprint (WF) of the meals served in order to identify hotspot meals and ingredients, and suggest simple, yet transformative, reduction measures. A case study is used to test the tool, comparing the impacts of 34 school meal recipes. The tool utilises secondary data to calculate values of CF and WF for a school meal from cradle to plate. This includes three phases: (1) food production, (2) transport of each ingredient to a generic school kitchen in the UK, and (3) meal preparation. Considerations for waste along the supply chain are included. After testing the tool against a set of nutritionally compliant meals, a sensitivity analysis was performed to investigate the influence of the origin and seasonality of the ingredients, transport mode and cooking appliances used on the final results. The results of the case study show the predominance of the production phase in the overall carbon footprint and that there is a strong tendency towards lower impacts for meat-free meals; however, this is not always the case, for instance some of the chicken-based meals present lower impacts than vegetarian meals rich in dairy ingredients. The sensitivity analysis performed on one of the meals shows that the highest value of CF is obtained when the horticultural products are out of season and produced in heated greenhouses, whilst the highest value of WF is obtained when the origin of the ingredients is unknown and the global average values of WF are used in the analysis; this defines a crucial data need if accurate analyses are to be uniformly possible. This article focuses on the potential offered by the public food sector for a transformative reduction in the environmental impact of urban food consumption. The results presented prove that careful menu planning and procurement choices can considerably reduce the overall environmental impact of the service provided without compromising quality or variety. This research thus supports those responsible for making these decisions via a user-friendly tool based on robust scientific evidence.

Recently, much of the literature on sharing in cities has focused on the sharing economy, in which people use online platforms to share underutilized assets in the marketplace. This view of sharing is too narrow for cities, as it neglects the myriad of ways, reasons, and scales in which citizens share in urban environments. Research presented here by the Liveable Cities team in the form of participant workshops in Lancaster and Birmingham, UK, suggests that a broader approach to understanding sharing in cities is essential. The research also highlighted tools and methods that may be used to help to identify sharing in communities. The paper ends with advice to city stakeholders, such as policymakers, urban planners, and urban designers, who are considering how to enhance sustainability in cities through sharing.

Highlights•Current and future transformative UUS options for cities are discussed.•Implications for achieving more liveable cities are highlighted.•Recommendations for an integrated mapping framework are made. AbstractAs populations grow in dense urban city centres, so too does the demand for space and natural resources. An option to combat this problem, all too often, has been to build denser and taller buildings in addition to transporting an ever-increasing abundance of resources (e.g. raw materials, water, energy and food) into the city whilst moving waste back out. This has major implications for liveable cities (LC), which in future policy terms might be considered to include aspects of (i) wellbeing, (ii) resource security (i.e. ‘one planet’ living) and (iii) carbon reduction (now enshrined in international law). An option that has been overlooked, and one which could add significantly to this LC agenda, is wider adoption of urban underground space (UUS).This paper looks at how UUS has been, or could be, used within cities now, and in the future, and investigates the implications for achieving more liveable cities, which includes cognisance of the potential for radical transformation rather than adaption. It is concluded that wider adoption of UUS brings with it many benefits; however to avoid many of the dis-benefits an improved system of management, planning provision (which includes integrated mapping frameworks that consider more readily the future) and policy application is required.
