Future scenarios provide challenging, plausible and relevant stories about how the future could unfold. Urban Futures (UF) research has identified a substantial set (>450) of seemingly disparate scenarios published over the period 1997-2011 and within this research, a sub-set of >160 scenarios has been identified (and categorized) based on their narratives according to the structure first proposed by the Global Scenario Group (GSG) in 1997; three world types (Business as Usual, Barbarization, and Great Transitions) and six scenarios, two for each world type (Policy Reform-PR, Market Forces-MF, Breakdown-B, Fortress World-FW, Eco-Communalism-EC and New Sustainability Paradigm-NSP). It is suggested that four of these scenario archetypes (MF, PR, NSP and FW) are sufficiently distinct to facilitate active stakeholder engagement in futures thinking. Moreover they are accompanied by a well-established, internally consistent set of narratives that provide a deeper understanding of the key fundamental drivers (e.g., STEEP-Social, Technological, Economic, Environmental and Political) that could bring about realistic world changes through a push or a pull effect. This is testament to the original concept of the GSG scenarios and their development and refinement over a 16 year period.

Purpose -Designers and planners in the UK are being asked by government to address sustainability. This paper seeks to explore how such issues can be addressed with the urban design process. From the literature, it is unclear when specific sustainability issues should be addressed, who actually makes decisions and what influences them, or how different stakeholders are engaged. Design/methodology/approach -A case study is presented, focusing on the early stages of an urban design and redevelopment process taking place in a deprived region of the UK. Interviews with key decision-makers and observations were conducted and subsequently analysed using content analysis. Findings -The findings show that the process adopted by clients and consultants was relatively similar to that identified by the literature. The importance of creating a sustainable community, and of addressing deprivation and poor services was recognised from the outset. Sustainability was referred to in the briefing to select a team of consultants to develop a vision and regeneration framework. However, specific problems related to sustainability, such as crime and poor health, were not communicated through the briefing documents, for fear of deterring private investment. Indeed, the need to attract private investment was a key aspect of early stage of the urban design process. Originality/value -This paper highlights potential difficulties of addressing sustainability at the early stage of the design process, when private sector backing is such a crucial component of the regeneration.

The urban design process must be transformed and improved if various stakeholders wish to create sustainable urban environments. Although the UK Government and other influential bodies have written many reports recently about the intimate relationship between urban design and sustainability, much more needs to be done to demonstrate how, when and where sustainability is embedded in the urban design process. There is also a need to understand who the decision makers are within this process and what influences their decisions. A clear picture of how the urban design decision-making process works from start to finish, and how sustainability is embedded within this process, can help to achieve the goals and objectives of urban sustainability in the 24-hour city. This paper begins by defining urban design and describing the urban design process, highlighting the major stages and the general tasks involved at each stage. Sustainability and urban sustainable development are briefly discussed next. The final section indicates, through case study research comprising the VivaCity2020 project, where sustainability may be embedded within the urban design process.
