City footprints and SDGs provide untapped potential for assessing city sustainability

Abstract

Cities are recognised as central to determining the sustainability of human development. However, assessment concepts that are able to ascertain whether or not a city is sustainable are only just emerging. Here we review literature since the Sustainable Development Goals (SDGs) were agreed in 2015 and identify three strands of scientific inquiry and practice in assessing city sustainability. We find that further integration is needed. SDG monitoring and assessment of cities should take advantage of both consumption-based (footprint) accounting and benchmarking against planetary boundaries and social thresholds in order to achieve greater relevance for designing sustainable cities and urban lifestyles.

Abstract

Whether or not a city achieves absolute sustainability is difficult to assess with existing frameworks. Here the authors, in a review, show that a further integration of consumption-based accounting and benchmarking is necessary to aid the monitoring and assessment of Sustainable Development Goals in cities.
