Fantastic breakdown of how built infrastructure participates in carbon cycles rather then just opposing them. The concrete carbonation finding completely flips the standard green vs gray framing. I ran numbers on building lifespans once and realized most climate models dunno how to account for the decades-long timescales of urban material flows. The soil respiration complexity is equally underrated. Helps explain why simple tree-planting initaives sometimes don't deliver expected results.

Thanks so much for your comment, this is a great point about the timeline of urban materials, it really takes a different way of thinking.
