Ecological Footprints and Lifestyle Archetypes: Exploring Dimensions of Consumption and the Transformation Needed to Achieve Urban Sustainability

Abstract

Abstract:The global urban transition increasingly positions cities as important influencers in determining sustainability outcomes. Urban sustainability literature tends to focus on the built environment as a solution space for reducing energy and materials demand; however, equally important is the consumption characteristics of the people who occupy the city. While size of dwelling and motor vehicle ownership are partially influenced by urban form, they are also influenced by cultural and socio-economic characteristics. Dietary choices and purchases of consumable goods are almost entirely driven by the latter. Using international field data that document urban ways of living, I develop lifestyle archetypes coupled with ecological footprint analysis to develop consumption benchmarks in the domains of: food, buildings, consumables, transportation, and water that correspond to various levels of demand on nature's services. I also explore the dimensions of transformation that would be needed in each of these domains for the per capita consumption patterns of urban dwellers to achieve ecological sustainability. The dimensions of transformation needed commensurate with ecological carrying capacity include: a 73% reduction in household energy use, a 96% reduction in motor vehicle ownership, a 78% reduction in per capita vehicle kilometres travelled, and a 79% reduction in air kilometres travelled.

Transition heuristic frameworks in research on agro-food sustainability transitions

“…The Social Practices Approach (SPA) bridges individual lifestyles and socio-technical systems Moore 2015). The theory of social practices investigates the social relations between producers and consumers, embedded in infrastructures Reckwitz 2002;Shove and Walker 2010;Southerton et al 2004;Spaargaren and van Vliet 2000;Warde 2005).…”

Environmental Carrying Capacity Assessment—the Policy Instrument and Tool for Sustainable Spatial Management

“…In this research, the assessment of CF uses the lifestyle archetypes of the city's residents and its suburban zone. As Moore (2015) mentioned, the consumption characteristics of the residents of a given area are a necessary basis to define whether the consumption needs are adequate with an ecological carrying capacity (Moore, 2015).…”

The acceleration of transitions to urban sustainability: a case study of Brighton and Hove

“…Much of the existing literature on urban sustainable development focuses on analysing specific aspects of achieving sustainability, such as (1) changing consumption patterns or lifestyles (e.g. see Moore (2015) who focuses on developing lifestyle archetypes coupled with ecological footprint analysis to develop urban consumption benchmarks), (2) urban planning practices (e.g. Malekpour, Brown and de Haan (2015) who look at how an incremental approach to infrastructure planning prevents progress), (3) introducing and implementing urban sustainability policies (e.g.…”
