Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Timber construction has a lower carbon footprint than concrete?

Yes. A meta-analysis of 18 side-by-side life-cycle comparisons across four continents found that substituting mass timber for conventional materials such as concrete reduced construction-phase emissions by about 69%. Several other studies also report lower carbon footprints for timber or timber-composite systems than concrete, though mostly for specific building types or regions.
