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.
The 29th Conference of the Parties to the UN Framework Convention on Climate Change (COP29) takes place between the 11th and 22nd of November in Baku, Azerbaijan. The event proposes a global gathering of business leaders, governments, and civil society with the aim of taking effective measures to limit global warming to 1.5°C above pre-industrial levels. As the construction industry is responsible for approximately 37% of global emissions, the conference is of particular interest to architects, urban planners, and researchers in this field.
“Landscape architects have started conversations about embodied carbon. There is a realization that we can no longer ignore the grey parts,” said Stephanie Carlisle, Senior Researcher, Carbon Leadership Forum and the University of Washington, during the first in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee.
The grey parts are concrete, steel, and other manufactured products in projects. And the conversations happening are laying the foundation for a shift away from using these materials. The landscape architect climate leaders driving these conversations are offering practical ways to decarbonize projects and specify low-carbon materials.
In an effort to find effective strategies to mitigate the adverse effects of climate change, the Biden-Harris administration has released a draft of a new legislative initiative that strives to impose a National Definition for Zero Emissions Buildings. Overseen by the U.S. Department of Energy (DOE), the draft proposes a standardized and verifiable base for defining the common minimum conditions for such buildings, as well as pathways for transparent verifications by public and private entities. DOE has now launched a ‘request for information' asking for feedback from industry, academia, research laboratories, and other stakeholders before finalizing the document.
For the opening of CAB 5, the 5th edition of the Chicago Architecture Biennial,Skidmore, Owings & Merrill (SOM) presented an eco-friendly alternative to traditional concrete. Named the “Bio-Block Spiral,” the installation is at The Mews in Fulton Market in Chicago. The creation was developed with Prometheus Material, a materials company that provides sustainable building materials for a carbon-negative future.
Designed by Atkins, a new zero-carbon secondary school in West Sussex has received planning permission from the West Sussex County Council. The school will be created at Homes England’s new Brookleigh development near Burgess Hill and will offer educational facilities to 900 local children. The building is designed to generate its own renewable energy on-site, eliminating the need for any fossil fuels. It also aims to achieve Passivhaus certification, the highest standard od energy efficiency a building can reach.
The Saudi Arabian government has released visuals of a 170-kilometer-long skyscraper as part of the NEOM project. Announced by crown prince Mohammed bin Salman, The Line is a reimagined urban development linking the coast of the Red Sea to the mountains and upper valleys of northwest Saudi Arabia. The compact structure, 200 meters wide, represents a social and economic experiment. The city aims to be zero-carbon, through the elimination of carbon-intensive infrastructures like cars and roads, and will operate on 100% renewable energy, including the operations of its industries.
Nowadays, the role of architects exceeds the limits of construction, reaching fields that are often unthinkable, but which nonetheless demonstrate a close relationship with the profession. If we go back in time, the fact is that many buildings, houses, monuments and even cities have been built intuitively without urban planning or renowned architects. Undoubtedly, today's architects are facing a great challenge that goes beyond demonstrating our skills and knowledge and extends to other areas that involve us, but we still don't know it. So we ask ourselves, what will be the profile of the architect of the future?
Kiribati has a population of around 110,000 people and its economy is centered on fishing and agriculture. Comprised of 33 islands in the Central Pacific, its highest point is only 81 meters above sea level, which makes it potentially the first country that could disappear completely due to global warming and the consequent rise in sea levels. The climate crisis has been a hotly debated topic in recent years and terms such as carbon footprint, greenhouse effect, atmospheric aerosols, and many others, are already staples in our vocabulary. Another widely spoken term is “net zero”, or net zero emission, used as a goal for buildings in different industries and countries. Basically, it means that the energy balance is zero.
According to a 2021 Food Waste Index Report by the United Nations, 17% of global food production goes to waste, becoming the third biggest source of greenhouse gas emissions. 11% of this waste is generated by households, not only contributing to the climate crisis, but also provoking large economic costs, biodiversity loss, and the rise of pollution levels at unprecedented rates. Therefore, considering the key role that architecture and design plays in providing more eco-friendly housing options, it is essential to adopt and enhance a more self-sustaining, zero-waste approach.

Australian research lab Finding Infinity has collaborated with architects, councils and investors to create a strategy that would turn Melbourne into a self-sufficient city by 2030. Building on exemplary case studies and scientific research, the initiative proposes a 10 step plan for the city’s transition from a consumer of resources to a zero-carbon urban environment.
A new six-story net-zero carbon office development in Vauxhall, London, UK has been granted planning commission by the city council to move further. Designed by FCBStudios, the timber workspace named Paradise, will transform an abandoned site on old Paradise street, and replace the existing disused roastery.
The concept of “decarbonization” has been in vogue recently in political speeches and global environmental events, but it has not yet gained enough attention in the field of architecture to profoundly change the way we design and construct the world of tomorrow. Buildings are currently responsible for 33% of global energy consumption and 39% of greenhouse gas emissions, indicating that architects must play a significant role if we are to stop or reverse climate change. With carbon acting as a universally agreed upon metric with which the greenhouse gas emissions of a building can be tracked [1], one of the most important ways through which this goal can be achieved is therefore the decarbonization of buildings.

Scheduled for completion in 2023, the new gateway structure will bring together Indigenous and Western cultures in both form and function.
'I just blew off the architecture profession, really. I mean, I have blown it off in my mind as a profession because it’s not addressing the issues that we face. So I coined a new word called ‘biotechure,’ and I use that. I would say I’m a ‘biotect.'
Coupdeville Architects has proposed designs for an environmentally responsible, carbon zero building in London. The earth sheltered structure is set into an existing slope on the site where it is arranged into three zones: an adult's area and a children's area both connected through larger living spaces. Following a requirement that the design provide areas "that allow the buildings occupants to be immersed on all sides by the site," all spaces are connected directly to the gardens. Not only has this allowed for optimal levels of sunlight into the rooms, but has allowed for excellent views from within and of the building.
