New briefing - From Asking Why to Thinking How: Emerging Challenges for Urban Climate Action
Vanesa Castán Broto and her colleague Linda Westman have recently published a briefing as part of The British Academy's COP26 Briefings Series aimed at raising awareness of the importance of our disciplines in understanding the complex human and social dimensions to environmental challenges and their solutions.
The briefing "From Asking Why to Thinking How: Emerging Challenges for Urban Climate Action" examines how cities can address climate change acting faster than other levels of government to open up opportunities to support innovation that can be propagated elsewhere.
The latest special reports from the Intergovernmental Panel on Climate Change suggest that more forceful action will be required to keep the world in a sustainable development pathway, keeping global average temperature changes under 1.5 degrees Celsius. Urban climate action is needed to step-up climate change ambitions. Empirical evidence shows that diverse actors, including local governments, private enterprises and communities, are already responding to climate change in cities and settlements. At the same time, the rapid pace of urbanisation in many regions of the world cast urban climate action as a race against time, as action is directed towards creating new urban infrastructure that avoids carbon lock-in and reduces the structural vulnerabilities to climate change. While the call for urgency is well taken, two challenges related to urban climate action are emerging. On the one hand, the current means to evaluate effectiveness of urban climate action in terms of emission reductions or reduction of risks do not capture the sometimes-imperceptible impacts of action taking place in cities and settlements. On the other hand, there is a risk that urban climate action may lead to unintended negative consequences, when the harms of climate action exceed its potential benefits.
