Cement is used in most city infrastructure, for industrial builds, etc. The demand for it in the U.S. probably dwarfs the UK several times over despite lumber use for houses, and poured concrete no longer popularly used for foundations. If you want to abate it, you'd need to look far beyond that particular use-case in the UK. I don't see low-hanging fruit here. Cement is reliable and inexpensive. There is R&D in the works for eco-cement, but this appears to be in early stages. It's possible to reduce emissions in its production in the first place. Notwithstanding the calcium carbonate, energy inputs (which are very high) could eventually not rely on fossil fuels. If the goal is to pursue an aggressive timeline for curbing CO2 emissions then probably CC & electrical will appear first.
