“The goal of the Structural Engineers 2050 (SE 2050) Challenge is to inspire structural engineers to contribute towards the global vision of Zero Carbon buildings by 2050, and to provide measurements of progress towards that vision. Much like the AIA 2030 Challenge does for operational energy in buildings, this SE 2050 initiative will challenge structural engineers to meet embodied carbon benchmarks and increasingly higher reduction targets in a “race towards the most efficient building” as we approach the year 2050.”
