Interesting how US emissions started falling around/post GFC when residential construction collapsed and have yet to recover. Us new house starts around ~60% of mid 2000s high, while piling on 40m to population. I wonder how much that contributed. I think 2/3 of US building stock is SFHs while construction accounts for than 1/3 of emissions and I think there's 6-7 million units of housing shortage from last decade of underbuilding.
