Join in the conversation as we talk through the criticality of whole life carbon assessment in understanding the consequences of our design and construct for buildings and infrastructure. The role of optimization and the circular economy in extending the lifecycle of assets to maximize the use of embodied carbon. The fundamental requirement to design for survival of inevitable climate change, and the absolute need to embrace technology if we are to shape a better world and  thrive in the future.
