Global construction and AEC activity is expected to grow 3.0% in 2025, but the carbon story around buildings is far less steady. Lifecycle emissions are often dominated by operations and maintenance, while energy demand and delivery systems keep shifting across countries. This post brings those building, materials, labor, and software signals into one set of statistics so you can see where architecture decisions lock in both performance and risk.
