A Berlin-based structural engineer, Stuart is Director and Global Circular Economy Skills Leader for international design and engineering firm Arup. He joined the Board of the Holcim Foundation in 2018 and has spent years forging pathways through the carbon equation, grappling with the gaps and unknowns.

In this podcast, he draws on his expertise in low-carbon buildings and the circular economy to guide us through key considerations and strategies. There’s no one-size-fits-all solution, but there’s much we can do to inch closer to low-carbon targets.

The discussion begins with materials and the emergence of another central theme: context. The decarbonisation of building materials is critical, says Stuart, particularly cement and concrete. However, it is just as important to make the best material choices for a project’s location and context.
