Given urbanism’s significant collective impact on planetary climate
change, many cities are working to reduce and eventually neutralise their carbon
emissions. Currently this is broadly limited to emissions for which city authorities
are responsible for. This is a positive endeavour but limited in terms of impact, as
most urban carbon emissions are produced beyond their direct responsibilities.
Whilst local authorities possess a significant degree of influence to reduce, remove
and ultimately manage city-wide carbon emissions, the essential task of expanding
their scope of accountability is one beset by varying complexities. Not only are there
numerous silos (not just in terms of disciplines but also data silos) to contend with,
but questions concerning public buy-in and environmental justice are equally
prescient. The task of city-wide urban carbon management is an inherently
transdisciplinary one, where the engineering challenge of carbon management in the
physical built environment is entwined with the socio-political complexities of the
urban realm. To this end, a review of the urban carbon management literature is
presented to identify the transdisciplinary challenges which have the potential to
limit city-wide carbon management - through which a definition for urban carbon
management is proposed. This is informing the development of a more systemic,
transdisciplinary approach towards engineering better urban carbon neutrality
approaches going forward, which is being piloted with cities as part of the European
Commission funded UP2030 project.
