The 29th United Nations Climate Change Conference (COP29) took place in Baku, Azerbaijan, from November 10 to November 24, 2024, amid a backdrop of escalating climate challenges. For cities, the epicenters of population growth, economic activity, and climate vulnerability, the outcomes of COP29 are particularly significant. As urban areas contribute over 70% of global carbon emissions and housing more than half of the world’s population, their consideration is pivotal in shaping global responses to the current crisis. In fact, cities are on the frontlines of the crisis, facing record-breaking heatwaves, catastrophic floods, and increasing economic losses from extreme weather events. In 2024 alone, urban areas worldwide experienced devastating climate impacts: flooding displaced millions in Africa, droughts crippled urban economies in South America, and storms caused widespread destruction in North America and Europe. The outcomes of COP29 directly affect urban planning, architecture, and sustainability efforts. From commitments to climate finance and carbon markets to renewable energy and resilience-building, the summit’s decisions provide a roadmap for transforming cities into hubs of climate innovation and adaptation. Below are the key takeaways from COP29 for the built environment and urban spaces.

Advancing Urban Climate Resilience Through Finance
For the first time in 15 years, COP29 established a long-term climate finance goal, setting the stage for transformative urban investments. Nations agreed to mobilize $1.3 trillion annually by 2035, including a short-term target of $300 billion annually to support vulnerable nations. These funds are intended to help cities and regions build resilience against climate risks such as flooding, extreme heat, and rising sea levels, while also advancing sustainable urban development. However, there remains a lack of clarity on how much of this funding will directly reach urban initiatives, as the agreement does not specify allocations for sectors or regions. Additionally, rapidly urbanizing regions, particularly in developing countries, require far greater resources to upgrade infrastructure and protect residents from escalating climate impacts. Overall, COP29‘s finance deal is a crucial starting point, and it requires strengthening to truly meet the needs of urban areas.
Carbon Markets as a Tool for Urban Innovation
A major breakthrough at COP29 was the adoption of a comprehensive framework for international carbon credit trading under Article 6 of the Paris Agreement. This mechanism enables nations and entities, including cities, to offset emissions and attract funding for climate projects. For urban areas, carbon credits represent a new financial pathway to support sustainability efforts. These markets can help fund initiatives such as energy-efficient building retrofits, low-carbon public transport systems, and urban green infrastructure. While this framework is a positive step, detailed guidelines for registries and reporting are still under development, determining whether carbon markets will generate the scale of funding needed. Nevertheless, proponents believe these markets could draw billions of dollars into urban sustainability projects, providing cities with the resources they need to innovate and adapt.

Responding to Escalating Climate Impacts
The urgency of climate adaptation for cities was underscored by the devastating events of 2024, which is on track to become the hottest year on record. Across the globe, urban areas faced extreme weather disasters. Flooding in Africa displaced millions, while landslides in Asia and droughts in South America disrupted urban economies and infrastructure. In Europe and North America, rain-triggered floods caused significant casualties and economic losses.
These crises highlighted the need for nature-based solutions to enhance urban resilience. Green roofs, urban forests, and permeable pavements can help cities manage water, reduce heat, and improve overall livability. Such approaches not only mitigate climate risks but also contribute to biodiversity and public health. COP29’s emphasis on climate adaptation provides a foundation for cities to prioritize these solutions, though more concrete commitments to urban resilience are needed.
Scaling Renewable Energy in Urban Areas
COP29’s pledge to triple global renewable energy capacity by 2030 offers cities a powerful opportunity to decarbonize their energy systems. Urban areas, as major consumers of energy, are at the heart of this transition. Investments in solar, wind, and nuclear energy can enable cities to reduce their reliance on fossil fuels while providing cleaner and more sustainable power for residents.
The retrofitting of older buildings with renewable energy systems is a particularly urgent priority for cities, as inefficient structures account for a significant portion of urban emissions. Despite these advancements, COP29 failed to expand on prior commitments to phase out fossil fuels. Fossil fuel interests continued to influence discussions, slowing progress on global energy transitions. Nevertheless, cities remain leaders in driving renewable energy adoption, and the outcomes of COP29 offer a framework to accelerate this transition.

Innovations in Sustainable Urban Design
Emerging technologies and materials showcased at COP29 promise to transform the built environment. From low-carbon construction methods to green roofs and vertical gardens, these innovations offer cities new tools to enhance sustainability and resilience. Advances in digital monitoring systems also enable cities to track energy use and emissions more effectively, providing data-driven pathways to reduce their environmental footprint. Architects and urban planners have a unique opportunity to integrate these solutions into their designs, creating cities that are not only more sustainable but also healthier and more livable. As urban areas continue to grow, COP29 outcomes underscore the importance of leveraging innovation to address the challenges of the future.
COP30 in Belém, Brazil
COP29 laid important groundwork for urban climate action, but significant challenges remain. The $300 billion finance target, while a critical step, falls short of what is needed to fully address the climate crisis in cities. Carbon markets and renewable energy commitments offer valuable tools, but their success depends on swift implementation and equitable distribution of resources. As cities prepare for COP30 in Belém, Brazil, the focus must shift to accelerating local initiatives, scaling innovative solutions, and ensuring that urban areas remain at the forefront of global climate action. With their unique ability to lead by example, cities have the potential to drive the systemic changes necessary for a sustainable future.
