Urban Light Pollution: How Cities Can Balance Safety, Nature and the Night Sky

Artificial light at night supports urban safety and mobility, yet excessive and poorly designed lighting affects ecosystems, sleep, energy use and the visibility of the night sky. This article examines the pace of light pollution, its consequences in Europe, and three possible approaches to designing safer and more sustainable urban lighting.

​Cycling Infrastructure in the Western Balkans: Why Streets Must Work for People, Not Cars

Cycling is increasingly recognised as one of the most effective investments in sustainable urban mobility, yet cities across the Western Balkans continue to struggle with car dependency and limited cycling infrastructure. In this interview, one of Serbia's leading cycling advocates discusses the progress being made, the political and cultural barriers that remain, and why cycling infrastructure in the Western Balkans is essential for healthier, more liveable and more resilient cities.

Urban Tree Planting: A Community Solution for Healthier Cities

urban-tree-planting-a-community-solution-for-healthier-cities
As cities become hotter and more densely populated, trees are no longer just an aesthetic feature but an essential part of urban infrastructure. This article explains why urban tree planting matters for public health, climate adaptation and community engagement, while introducing Serbia's "Plant Your Shade" initiative.

The tree in the machine: Why urban heat resilience planning still can’t see the tree

urban heat resilience
Urban heat resilience strategies increasingly rely on digital tools, heat mapping, and building performance models, yet trees remain largely excluded from the systems used to guide investment and regulatory decisions. This article examines why urban forests continue to be treated as contextual elements rather than critical cooling infrastructure, despite extensive evidence of their thermal, social, and public health benefits. It argues that integrating tree canopy data into urban heat resilience planning is essential for equitable and effective climate adaptation.

Why Smart City Projects Fail: Lessons from an 80-Million-Yuan Digital Infrastructure Project

Underused smart city operations center with inactive monitoring screens and empty workstations, illustrating the challenges of digital infrastructure projects and smart city governance.
A county-level smart city project in China saw six of its seven sub-projects become idle despite significant public investment. This case study explores how planning gaps, fragmented data systems and governance challenges can undermine even the most ambitious digital infrastructure projects.

Is the Earth Getting Hotter? New WMO Forecast Charts a Path to Unprecedented Global Warmth

Is the Earth Getting Hotter?
This comprehensive analytical review breaks down the newly released WMO Global Annual to Decadal Climate Update for 2026–2035. Presenting data from 13 leading global prediction centers, it details a critical 91% probability of temporarily breaching the 1.5°C warming threshold within the next five years. Ultimately, the analysis translates these accelerating macroeconomic climate risks into actionable strategic adaptations required by modern urban planners and renewable energy engineers.

Beyond Green Claims (Part I): The Operational Reality of Sustainable Sport Events

Operational preparations behind sustainable sports events, including logistics infrastructure and event operations supporting major international competitions.
Major sporting events increasingly promote ambitious sustainability goals, yet their greatest environmental impacts often remain hidden within complex operational systems. Drawing on examples from Formula E, Formula 1, the Olympic Games, and other international events, Pierluigi Zacheo explores why transport, logistics, procurement, governance, and planning decisions ultimately determine whether sustainability commitments translate into real-world results.
