The Next Urban Evolution: Why Materials Matter

What if one of the most consequential climate decisions in the built environment is also one of the least visible?

As countries compete for growth, resilience and global relevance in an era of climate transition, one question is rising to the forefront: how do we build environments designed not only for speed and scale, but for longevity?

The next generation of cities will be shaped not only by energy systems and digital technology, but by the materials that enable lasting infrastructure, circular and modular buildings and resilient mobility systems. The material choices made today will influence maintenance cost, resource dependency and carbon management for decades to come.

This dialogue brings together leaders from industry, innovation and policy to explore why durability, circularity and low-emission materials are becoming strategic enablers in the transformation of modern societies, and what it takes to build cities prepared for the next century.

Be part of the conversation shaping what comes next and request your invitation!.
