There is irrefutable evidence that the climate is changing. There also is strong evidence that this is largely a result of human activity, driven by our insatiable consumption of resources, growing populations, unsustainable migration patterns and rapid overdevelopment in cities that are resulting in heavy ecosystem services losses. Humankind's solutions to these problems do not always work, as many rely upon quantities of resources that simply do not exist or that could not support the rate of change that we are facing, behaviour changes that sit uneasily with our current consumption patterns and quality of life aspirations, and government policies that emphasise long-term sustainable gain but potential short-term economic loss for businesses and local people. A radical revisioning of the problem is needed, not only to reverse current trends, but also to contribute positively to the sustainability and wellbeing of the planet, now and in the future. This proposal is that radical new vision, adopting a 'whole of government' focus to the changes needed in the ways that societies live, work, play and consume, balancing social aspirations against the necessary changes, and using CO2 emissions as a proxy measurement for the harm being done to the planet and the resources (particularly energy) that we use. Through the development of a city analysis methodology; engineering design criteria for quality of life and wellbeing; engineering design criteria for low carbon pathways and; radical engineering approaches, strategies and visioning-all generated in a multidisciplinary context-we aim to deliver a range of engineering solutions that are effective in sustaining civilised life, in an affordable and socially acceptable style. Our vision is to transform the engineering of cities to deliver societal and planetary wellbeing within the context of low carbon living and resource security. We seek to prove that an alternative future with drastically reduced CO2 emissions is achievable in a socially acceptable manner, and to develop realistic and radical engineering solutions to achieve it. Certain techno-fixes for a low-carbon society have been known for some time (e.g., installing low energy appliances in homes), but are not always deemed successful, in part because they have not been deemed socially acceptable. Current aspirations for material consumption are driven by social factors and reinforced by social norms, yet recent research shows that meeting these aspirations often does not enhance wellbeing. Thus, the challenge the research community faces is to co-evolve the techno-fixes with people's aspirations, incorporating radical engineering strategies within the financial, policy/regulation and technical contexts, to re-define an alternative future. A roadmap is required to chart the path from here to there, identify potential tipping points and determine how to integrate radical engineering strategies into norms. However, this roadmap can only be considered once that alternative future has been established, and a 'back-casting' exercise carried out, to explore where the major barriers to change lie and where interventions are needed. Our ambition is to create an holistic, integrated, truly multidisciplinary city analysis methodology that uniquely combines engineered solutions and quality-of-life indicators, accounts for social aspirations, is founded on an evidence base of trials of radical interventions in cities, and delivers the radical engineering solutions necessary to achieve our vision. We seek to achieve this ambition by using a variety of innovative and traditional approaches and methods to undertake five research challenges, which are outlined in detail in five technical annexes.

In a circular economy, clean growth is achieved by increasing the value derived from existing and planned economic infrastructure, products and materials which in turn significantly reduces or eliminates negative externalities. Increased value can be achieved by maintaining the integrity of a product or material at a higher level, using products longer, cascading their use in adjacent value chains and designing pure, high quality feedstocks (avoiding contamination and toxicity). A circular economy approach to plastics addresses simultaneously the accumulation, impact and costs in the environment whilst maintaining applications for multiple high value purposes. To translate potential to reality requires new circular plastics systems that a) co-ordinate and integrate key system players and activities across the value chain b) are underpinned by rigorous scientific research evidence; c) promote novel and creative approaches to the circulation and cascading of plastics in society and; d) demonstrate and proof points in support of decision-making and action at varying s Ths proposal will connect excellent institutional research activities within a single highly visible Multidisciplinary Plastics Research Hub - "ExeMPlaR" led by the University of Exeter to provide the first stage in a comprehensive, systematic and coordinated approach to the formation of a novel and creative circular economies, using regional demonstrators in the SW of England to test a number of key building blocks. This will be based on system-oriented innovation and high quality inter-disciplinary and collaborative scientific research within a proven, cohesive circular economy framework to address both the cause(s) of the problems and efforts to solve them rather than just treating the symptoms. This research effort involves the demonstration of the technical feasibility and superior economic, material, health, environmental and social value of a circular economy system re-design against a current linear base case. Expert-led, technical solutions by themselves however are unlikely to be effective and require in addition a theory of change that connects human behaviours, social systems and structures with circular economy principles. ExeMPLaR will bring together business, policy, community, environmental, and media representatives with a shared 'narrative' (in this case , a new Circular Plastics Economy) values and ideas, to jointly identify and work on a complex set of activities and pilot projects, that together form an effective innovation ecosystem (WP1). EXeMPLaR will undertake a novel and creative approach to impact by applying the principles of networks of transformative change into a circular economy project. ExeMPLaR therefore focusses on the current plastic system and address the potential to create higher value from existing plastic flows, create new opportunities for regional design and closed loop manufacturing and community initiatives, reduce negative externalities and create networks for transformational change to co-design and support systems innovations required at regional scale. To achieve this vision many challenges have to be overcome. To start the process of creating effective regional plastics economies, ExeMPLaR will synthesise an authoritative evidence base to inform regional actions, interventions and evaluation. This will build on a wide range of world leading plastics research at Exeter. We will translate these findings into the first stage of an evaluation tool and apply these to three front runner regional interventions, and additional smaller projects co-designed and prioritized by our network, to test opportunities for re-using, replacing or eliminating certain categories of fossil fuel derived plastic. After testing the impacts, outcomes and value creation potential we will address the potential challenges and enablers to replication and scaling these interventions at regional and national scale.

The aim of the Sustainable Eastside Project is to explore how sustainability is addressed in the regeneration decision-making process, and to assess the sustainability performance of completed development schemes in Birmingham Eastside against stated sustainability credentials and aspirations. The incorporation of sustainability into an urban regeneration program, such as Birmingham Eastside, appears best conceptualised as a complex decision-making process carried out by stakeholders who are embedded within the development process. The barriers to and enablers of sustainability (as identified in Phase I of this project) appear at various moments or locations within this complex. The timing and context of decisions are critical (examined in Phase II), and can cause path-dependency which then limits how sustainability features in final development plans. In Phases I & II, the research set in place a framework of cross-disciplinary knowledge and key partnerships; highlighted the importance of coherent integration of the three pillars of sustainability to enable the complexity of achieving urban sustainability to be sufficiently grappled with; gained access to key decision-making forums in Eastside; built strong links with key stakeholders in the area; and firmly integrated into the policy agenda for Eastside. In addition, researchers are working to establish a cross-cutting baseline dataset of developments in Eastside rigorously to measure change over time and the impact of particular decisions on the sustainability of the overall urban regeneration programme. In so doing the foundations for a zonal urban regeneration case study site are being established, augmented by the creation of a study facility, with library and hot desking, now available for researchers from SUE / IEP consortia, to study the application of research to practice. The emerging findings of Phase II have allowed researchers to develop a series of hypotheses about the timing of decisions for sustainability in a range of decision-making forums, and the extent to which path-dependency becomes problematic. In Phase III, a suite of innovative analytical tools will be employed to elucidate further the complexities and interactions of the key elements of the sustainability vision for Eastside. First, a Development Timeline Framework (DTF), a multi-disciplinary tool that makes explicit the path dependency of decisions toward achieving sustainability goals, and the conflicts and synergies between different sustainability objectives, will be used as the basis for further research. Second, a cross-cutting Sustainability Checklist (SC) applied to the DTF will allow each researcher to analyse the impact of timing and context of decisions for each sustainability element (e.g. biodiversity, public participation, space utilisation, local sourcing, and recycling). Third, an Industrial Ecology (IE) analysis will follow particular resources (e.g. water, aggregates) thus highlighting their interdependence, while a Social Impact Assessment (SIA) approach will enable assessment of the socio-cultural aspects of sustainability (not covered by the IE approach). This suite of tools underpins the delivery of the work package aims. This analysis will be undertaken on a case history site basis, using development sites within Eastside that are all currently 'live,' each site representing a different conceptualisation of sustainability. This provides a unique opportunity to evaluate the specific impact of early thinking about sustainability in the planning and design stages, and the impact of this timing and path-dependency on sustainability performance in the final built form.
