Frequent Flyers for Sustainable Cities? Rethinking the Urban Mega-Conference

Markus Appenzeller

The World Urban Forum is holding its 13th session in Baku this week. Every time I travel to one of these mega conferences, I find myself questioning their purpose. To stop these thoughts from haunting me like that little angel and that little devil on your shoulders, I have decided to put them on paper and let them argue with each other:

The Case for More Conferences, Not Fewer

The Human Infrastructure of Urbanism

Every few years, the urban world gathers somewhere under banners carrying familiar words: resilience, inclusion, sustainability, innovation. This year it is Baku. Next time it will be somewhere else. And every time, somebody asks the obvious question: why are we still doing this?

It is a fair question. Thousands of people flying across continents to discuss climate change and sustainable cities is not free from contradiction. Yet dismissing gatherings like the World Urban Forum as empty spectacles misses something fundamental about how cities actually evolve.

Urbanism is not only about plans, regulations, data, or infrastructure. It is ultimately about relationships. Cities are shaped through negotiations between governments, investors, activists, engineers, planners, communities, academics, and politicians. The urban world runs on trust networks as much as on technical expertise. Those networks are still built most effectively in person.

There is a difference between exchanging information and building understanding. Online meetings are efficient, but they rarely create the depth of connection needed for long-term collaboration. A Zoom call can transfer knowledge. It cannot easily generate trust, nuance, or shared ambition. Conferences still matter because human beings remain physical and social creatures.

Beyond the Official Program

The real value of major conferences is often invisible in the official agenda. It happens in corridors, over dinners, during city walks, or in conversations after panels. Entire collaborations begin in accidental encounters.

A mayor from Africa meets a transport planner from Europe. A housing activist from Latin America confronts a technocrat from the Gulf. A young urban designer finds a mentor. An NGO discovers a financing partner. None of this appears in the final conference report, yet these interactions often become the real legacy of the event.

Cities themselves also become part of the learning process. Visiting Baku is not the same as reading about Baku. Urbanism is spatial and sensory. One learns by walking streets, observing public life, experiencing infrastructure, seeing inequality, density, mobility, climate adaptation, and architecture directly. Physical presence still produces insights that digital platforms cannot replicate.

A Global Urban Conversation

The world’s urban problems are increasingly interconnected. Housing shortages, migration, flooding, energy transitions, extreme heat, infrastructure finance, and demographic change do not respect borders. Conferences provide rare opportunities for comparative learning across political and cultural systems.

The urban sector also suffers from fragmentation. Planners speak to planners, financiers to financiers, politicians to politicians. Large gatherings create temporary spaces where these worlds overlap. In a period when cities are expected to solve ever larger global crises, such spaces may actually become more necessary rather than less.

Critics often underestimate the symbolic importance of these forums as well. Conferences signal that cities matter politically. They create visibility for local governments in a world still dominated by national politics. They remind participants that urbanization is not merely a technical issue but one of the defining political questions of the century.

The Cost of Isolation

The alternative to imperfect conferences is not automatically a better system. It may simply be fragmentation, isolation, and weaker international cooperation.

There is a growing temptation to believe that digital connectivity has made physical gatherings obsolete. But the opposite may be true. The more digital communication dominates professional life, the more valuable genuine face-to-face encounters become. In a world saturated with screens, physical presence acquires new meaning.

Conferences are imperfect, expensive, and often repetitive. Yet cities themselves are imperfect, expensive, and repetitive. Urban progress rarely happens through sudden breakthroughs. More often it emerges through slow accumulation of relationships, exchanges, and shared experiences over decades.

Perhaps the real question is not whether we still need conferences. It is whether we are willing to invest in the human infrastructure that makes cooperation between cities possible at all.

The Conference as Urban Theater

A Ritual from Another Century

There was a time when large international conferences were indispensable. Information moved slowly. International networks were limited. Air travel symbolized openness and global exchange. Gathering thousands of people in one place created access to ideas otherwise impossible to obtain.

That world no longer exists.

Today, urban conferences often feel like institutional habits surviving long after the original reasons for them disappeared. Tens of thousands of delegates fly around the world carrying laptops and smartphones that already connect them instantly to nearly everyone they will meet. The conference becomes less a necessity than a ritual.

The contradiction is particularly sharp in the urban sector. Sustainability conferences generate enormous carbon emissions. Climate forums require intercontinental flights, luxury hotels, exhibition halls, logistics operations, catering systems, and temporary infrastructures of staggering scale. Entire industries now exist around conference tourism while participants discuss decarbonization inside heavily air-conditioned venues.

It increasingly resembles a performance of sustainability rather than sustainability itself.

The Repetition Machine

Anyone who attends enough urban conferences notices the same patterns. The same language circulates endlessly: resilience, innovation, smart cities, inclusion, livability, nature-based solutions. The same panels reappear with slightly different titles. The same presenters move from city to city repeating familiar narratives.

Conferences create the illusion of movement even when very little changes on the ground.

The problem is not only repetition. It is abstraction. Urban conferences often drift away from the difficult realities of implementation. Speakers discuss visionary frameworks while housing shortages deepen, infrastructure decays, and political systems struggle to deliver even basic urban services.

The conference itself gradually becomes the product. Visibility replaces impact. Networking replaces accountability.

The Economics of Presence

Much conference participation is driven by institutional pressure rather than genuine necessity. Organizations attend because absence feels risky. Cities fear invisibility. Consultants seek clients. Universities seek exposure. Politicians seek photographs. Entire professional ecosystems now depend on being seen at global events.

This creates an urban elite that travels continuously between conferences while remaining increasingly detached from everyday urban reality. Ironically, many people shaping discussions about inclusive cities participate in highly exclusive gatherings inaccessible to most citizens.

The inequality built into the system is striking. Smaller municipalities, grassroots organizations, and younger practitioners are often excluded by travel costs, visa barriers, registration fees, and time commitments. Despite the rhetoric of global inclusion, many conferences remain dominated by a relatively mobile international class.

A Failure of Format

The deeper problem may be structural. Conferences compress complex urban issues into short presentations and symbolic declarations. They encourage polished storytelling rather than difficult implementation discussions. They privilege charisma over depth and consensus over conflict.

Urban transformation requires long-term engagement, not temporary spectacles. Cities do not change because thousands of people gather for four days in a convention center. They change through patient local work, political struggle, institutional reform, and continuous experimentation.

The format itself increasingly feels out of sync with the nature of contemporary urban challenges. Climate adaptation, housing transitions, mobility reform, and energy transformation demand sustained collaboration embedded in places – not occasional bursts of international conversation disconnected from implementation.

Perhaps future historians will see the mega-conference as a distinctly late-20th-century phenomenon: a product of globalization’s optimistic phase that survived into a more climate-conscious and digitally connected era largely out of institutional inertia.

Beyond the Mega-Conference

The future probably lies somewhere between these two positions. Human beings still need physical encounters. Cities still benefit from international exchange. But the format of the traditional mega-conference increasingly feels oversized, carbon-intensive, expensive, and performative.

The challenge is therefore not whether urban gatherings should disappear, but how they should evolve.

Future formats could become smaller, more regional, and more embedded in real urban conditions. Instead of thousands of delegates flying briefly into one location, urban networks could organize longer residencies, collaborative field laboratories, rotating city workshops, or peer-to-peer exchange programs tied directly to implementation projects.

One can imagine mobile conferences traveling by train across regions, temporary urban camps hosted inside neighborhoods rather than convention centers, or multi-city learning journeys where practitioners spend weeks working together on actual problems. Smaller interdisciplinary groups could move through cities slowly, engaging directly with communities and municipal teams rather than consuming endless panel discussions.

Gatherings could also become radically more accountable. Every conference might require measurable post-event commitments, strict carbon budgets, local impact assessments, and mandatory engagement with host-city realities beyond curated tours.

The essential question is not whether people should gather physically. They should. Urbanism is too human, too spatial, and too political to become entirely virtual. But the inherited conference model increasingly belongs to another era. The next generation of urban exchange will need to be less theatrical, less centralized, more experimental, and much closer to the messy realities of cities themselves.
