By 2050, over two-thirds of the world’s population will live in urban areas. Faced with this demographic boom and the intensifying climate crisis, cities are on the front lines. Pollution, sprawl, concrete, inequality… symptoms of an outdated urban model are piling up. Yet another path is emerging: that of the green city, resilient, inclusive, and sustainable.

In Will the Cities of the Future Be Green?, Léwis Verdun explores this emerging urban paradigm with clarity and precision. This article offers an indirect lens on the topic, tackling a crucial question: how can cities drive ecological transition without sacrificing quality of life?

Reinventing the City: An Ecological and Social Imperative

Cities can no longer expand following 20th-century models. Today, they consume 75% of the world’s energy, produce over 70% of greenhouse gas emissions, and concentrate the effects of climate change (heat islands, water stress, social vulnerability).

Yet cities also hold enormous potential for transformation. Thanks to dense networks, local innovation, and economies of scale, they can become living laboratories for applied ecology.

The “green city” isn’t just green rooftops or bike lanes. It implies a systemic overhaul of urban functions—energy, mobility, food systems, housing, and governance.

The Pillars of a Sustainable City

Creating a green city requires several interdependent strategies, as described in Léwis Verdun’s book:

Decarbonized mobility
Reducing car dependence is essential. That means expanding public transport, building safe bike lanes, encouraging walking, and redesigning urban logistics.

Local renewable energy
From positive-energy buildings to solar panels and geothermal grids, cities like Freiburg or Malmö already lead the way.

Urban biodiversity
Green spaces, urban forests, and ecological corridors are vital—not luxuries. They reduce heat, improve air quality, and foster wellbeing.

Circular economy and resource efficiency
Urban areas can adopt local material flows, sustainable construction practices, and waste management that support a circular model.

Civic participation
The future city must include its residents. Participatory planning, citizen budgets, and open consultations are essential for building inclusive, accepted transitions.

Inspiring Examples: Cities Leading the Way

Some pioneers are already showing what’s possible:

Copenhagen is on track for carbon neutrality by 2025 with clean energy and integrated transport.

Freiburg, Germany’s “green capital,” combines sustainable housing, soft mobility, and democratic governance.

Portland has built a model of dense, mixed-use, and environmentally conscious urban planning for more than two decades.

These cases prove that ecological transition in cities is achievable and desirable, if treated as a collective goal.

Making Cities Livable and Sustainable for All

The real question isn’t just “Will cities be green?” but “Will green cities benefit everyone?” Behind eco-friendly discourse often lies green gentrification, where only the privileged access urban innovation.

The goal must be to build cities that are both sustainable and inclusive, where ecology and social justice go hand in hand. It takes long-term planning, democratic oversight, serious investment—and political will.

Future cities can be powerful engines of positive change—or enclaves of climate-driven inequality. The choice is ours.
