On Earth Day 2025, observed annually on April 22, we are once again reminded of the urgent environmental and sustainability challenges that face our planet—challenges that continue to evolve alongside global economic, political, and cultural shifts. The building and construction industry remains one of the most critical sectors in the effort to manage and reduce global carbon emissions. This year, these issues are being addressed through increasingly diverse lenses, calling for more holistic and integrated approaches. It's vital that we view sustainability not as a one-size-fits-all solution, but as a multi-scalar effort—one that spans from large-scale urban development and strategic planning, to the advancement of sustainable materials, and even to temporary, thought-provoking interventions like exhibitions and installations. In doing so, we reaffirm our commitment to reducing our collective carbon footprint, while shaping a built environment that promotes human well-being and planetary health.

Recent news headlines from the African continent show a variety of urgent issues affecting urban centers: severe flooding threatens Kenya's capital, Nairobi; the light rail system in Addis Ababa, Ethiopia, is faltering after a successful start. Meanwhile, in Egypt's capital, Cairo, new infrastructure and housing expenditures proved too steep and necessitated a government bailout. African cities face a plethora of problems but they also hold the potential to improve countless lives. As South America shares stark similarities in its history with that of Africa, it could provide both a point of reference and a positive example for tackling these concerns at an urban level.

In the rapidly evolving landscape of the 21st century, cities have emerged as models of innovation in terms of sustainable development goals. Cities creatively address pressing urban challenges, including density, transportation, housing, and resilience. They hold the potential to pioneer a comprehensive climate agenda, serving as laboratories for sustainable initiatives, cross-sectoral innovations and community-oriented strategies. Cities act as catalysts for revolutions, implementing impactful solutions that can be applied worldwide.
Copenhagen was founded in the 12th century and has undergone numerous transformations to establish itself as an urban benchmark of the 21st century. Its dynamic urban environment stands as an exemplar of architecture's importance and crucial role in shaping a sustainable future for cities. Confronting global challenges like mobility, urban development, and eco-friendly construction, the city is an inspiring model. This is why in 2023, the Danish city was named the World Architecture Capital by UNESCO-IUA, positioning Copenhagen as a platform for discussions on climate, sustainable solutions, and livability.
In this context, Danish architects such as Anders Lendager have been asked about their perception and interaction with their favorite places in the city, providing valuable insight into what makes Copenhagen unique. Lendager, the CEO and founder of Lendager Group, has been the designer behind eco-village projects, the Danish Pavilion in Milan, and a skyscraper built from recycled materials. Collectively, these projects showcase the capacity to translate the core principles of sustainable cities into tangible components, prioritizing human well-being and fostering circular economy models.
