CRA–Carlo Ratti Associati and Höweler + Yoon have unveiled images of AquaPraça, a floating gathering space for global climate dialogue set to anchor COP30 in Belém, Brazil. Currently under construction in northeastern Italy by steel construction company Cimolai, the project will be unveiled at the 19th International Architecture Exhibition of La Biennale di Venezia on 4 September 2025. It will then embark on a transatlantic journey to Brazil, where it will form part of the Italian Pavilion at COP30, held from 10 to 21 November 2025. Following the event, it is intended to become a permanent floating landmark in the Amazon as part of Belém's cultural infrastructure.
In recent weeks, cities around the world have introduced new policies, recovery efforts, and infrastructure projects that reflect growing pressure to adapt to climate realities. From Southern Europe to South America and the United States, these urban updates address both immediate challenges and long-term shifts in how the built environment is governed, designed, and inhabited. Some initiatives focus on regulation, tightening building codes in fire-prone areas or reforming aging safety systems, while others spotlight large-scale investments tied to global events such as COP30 and the Venice Architecture Biennale. This edition of Architecture Now gathers a selection of city-led actions and collaborative efforts that point toward a more resilient, responsive future for architecture and urban life.
2025 promises to be a landmark in architecture, heralding a vibrant renaissance of creativity and exploration. As societies confront challenges such as climate change, rapid urbanization, and technological evolution, architecture is both a mirror to these dynamics and a compass pointing toward a sustainable and inclusive future. This year's architectural calendar offers abundant opportunities to celebrate the discipline's transformative power — from boundary-pushing festivals to thought-provoking exhibitions that explore pressing cultural and environmental narratives.
From well-established biennials to inaugural gatherings, including the World Architecture Festival 2025, Desert X Al Ula, and the COP Climate Conference, the 2025 calendar highlights themes such as sustainability, heritage, and community. These events underscore architecture's unique ability to shape a better future, addressing global challenges while honoring cultural diversity and design ingenuity.
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.
As the architectural landscape continues to evolve in response to pressing global challenges, events such as biennales, design weeks, and fairs play an instrumental role in shaping the profession's future. These gatherings facilitate the exchange of innovative ideas, the exploration of sustainable practices, and the fostering of collaboration among architects, designers, and urban planners. They serve not only as platforms for showcasing cutting-edge designs but also as forums for critical dialogue about the built environment's impact on society and the planet.
Happening worldwide from September to December 2024, a variety of significant events hope to engage the architectural community. The World Urban Forum in Cairo focuses on local sustainable actions, while Dubai Design Week showcases innovative design in the Middle East. The World Architecture Festival in Singapore features live project presentations, and the Architecture & Design Film Festival in New York offers compelling narratives critical to contemporary discourse.
In November of 2022, the coastal city of Sharm El Sheikh, Egypt, hosted the 27th convention of the United Nations Conference of the Parties, known as COP27. Since signing the Paris Agreement in 2015, the nearly annual conference has gained momentum as a global leader in sharing knowledge and developing frameworks to mitigate climate change worldwide. While the more recent COP28, held in Dubai in 2023, focused on conversations of energy production, this previous conference focused on urban contexts, as they deal with the urgent need for incorporating loss, damage, and climate reparations into climate action plans. As two years have now passed since COP27, it is important to revisit these discussions and hold governing bodies accountable for the promises made and the benchmarks set for climate change mitigation. One of the most ambitious plans from COP27 highlights an urgent debate in our urban environments: how will we define loss, damage, and climate reparations in the twenty-first century?
