The rise in the influence of sustainability principles has resulted in an almost overwhelming number of ways of defining, measuring and assessing sustainability. For sustainability measurement to be accurate it must have a clearly defined ‘sustainability space’, be designed for the context in which the measurements are to be taken, evidence a clear causal chain and make explicit interdependencies. The degree to which current sustainability methods meet these criteria is varied.
Cities play an important role in a country’s ability to become more sustainable. In order for cities to move towards sustainability, it is important first to understand how they function and how well they perform. This provides a baseline against which to identify and prioritise aspects that would benefit from change and assess the impact of any proposed solutions. Gaps in performance can then be identified, barriers to achieving a sustainable future elucidated and robust solutions designed and assessed. Care must be taken, however, that in moving towards a more sustainable future the liveability of cities is not compromised.
The City Analysis Methodology (CAM) is an innovative urban analysis framework for holistically measuring the performance of UK cities with regard to well-being, resource security and CO2 emissions. It demonstrates the need for, and defines the parameters for, sustainability solutions (decisions being made now in the name of sustainability) that do not compromise wellbeing and provides a model for other countries to leverage the sustainability of their cities.
