The setting of concrete is the third single largest emittor of CO2.
Repurposing an otherwise sound structure is thus an extremely effective emission saving measure. Second best seems to use cross laminated timber, with which all but the tallest buildings could be constructed. They'd be carbon sinks instead of emitors.
- credit_guy 4y agoHere's what wikipedia has to say about the environmental impact of concrete [1]: Between 4-8% of total global CO2 emissions come from concrete. By the way, this is during the production of concrete. When concrete sets, it actually absorbs CO2, it does not emit. The amount of CO2 that it absorbs does not appear to be significant however.
