Urban climate action: Reflecting on social transformation ahead of COP30
As Belém is hosting the world’s climate leaders, I4C reflects on the transformative power of data, collaboration, and local knowledge.
In the lead-up to Belém, Brazil, the European Committee of the Regions called on the COP30 Presidency to give greater recognition to the pivotal role of local and regional governments in advancing just and sustainable climate action.
As global ambitions translate into local responsibilities, the question becomes how to equip cities with the knowledge and tools to turn commitments into concrete action.
Impetus4Change (I4C) will be following the discussions closely, reinforcing the message that accessible, high-quality climate information at the local level is essential to achieve transformative change in cities.
What’s at stake for cities at COP30?
Looking at the programme, it seems the COP30 organisers have done their homework: themes of urban resilience, locally led adaptation, nature-based solutions, and decentralised climate action are set to define the conference agenda, fully in line with the UNFCCC Action Agenda’s Pillar 4, ‘Building resilience for cities, infrastructure, and water’.
Cities are at the forefront of the global conversation on climate resilience — but one essential factor often gets overlooked: the potential of climate-related data. Local governments face floods, heatwaves, and aging infrastructure, yet limited resources, fragmented datasets, and bureaucratic barriers make it difficult to turn science into action. Amid the abundance of scientific information, cities often struggle to translate research into practical insights that guide adaptation policies. Ensuring that cities discuss how to harness data for climate resilience should therefore be a key part of the agenda.
COP30’s Cities & Regions Hub, co-convened by UN-Habitat and Brazil’s Ministry of Cities, will serve as a platform to connect international commitments with on-the-ground urban action. The hub will spotlight how cities can implement nature-based and low-carbon solutions, harnessing multilevel collaboration and innovations…
“Data is a cornerstone of effective resilience planning and action – but only when it is accessible and usable at all levels of decision-making”, says Luca Arbau, Senior Expert for Resilience and Climate Adaptation at ICLEI Europe.“Projects like I4C play a crucial role in enhancing the quality, accessibility, and use of climate information at regional and local scales.”
Initiatives such as Brazil’s AdaptaCidades, aiming to equip municipal and state officials to design local adaptation and resilience strategies, illustrate this shift toward “climate federalism”, a strategy which emphasises the need for integration of subnational governments, such as cities and regions, into global climate action. By linking national policy with local expertise, AdaptaCidades embodies the kind of multi-level governance and data-informed decision-making that COP30 aims to champion.
Where does I4C fit in with COP30 priorities?
It is encouraging that international climate summits like COP are increasingly acknowledging the escalating climate risks cities face — but awareness alone isn’t enough.
I4C is bridging the gap between the nuances of city administrations and real-time climate information (including climate data, but also other demographic, health, and historical model inputs).
There are at least 4 ways I4C is helping to turn COP30’s pledges into real-world progress:
- Strengthening locally led adaptation: By co-producing knowledge with local stakeholders, I4C ensures that adaptation strategies are grounded in local realities and community needs.
- Enabling urban resilience: I4C develops tools that help cities assess vulnerabilities and plan for climate impacts on housing, health, infrastructure, and mobility.
- Supporting nature-based solutions: Through data and analysis, I4C helps identify where nature-based approaches, like urban forests or wetland restoration, can deliver both ecological and social benefits.
- Bridging science and policy: By making climate information more transparent and usable, I4C helps connect the research community with city officials, aligning research with the Action Agenda’s goal of building resilience across scales.
I4C researchers have recently been selected to join global experts shaping climate-resilient cities in the IPCC’s Special Report on Climate Change and Cities.
From research to real-world impact
As COP30 unfolds, we are reminded that the challenge is no longer about setting targets but about turning commitments into implementation. For this, cities need evidence, partnerships, and local capacity.
By working at the interface of science, policy, and society, I4C exemplifies how research can accelerate action, supporting cities in adapting to a changing climate while ensuring that no community is left behind.
Stay tuned for updates on COP30 and see how I4C’s work is driving urban transformation.
