Deriving embodied carbon factors from scratch

摘要

While the above examples are for products on a project in Rwanda, the principles can be applied to many other materials or products, such as nail-laminated timber or precast concrete, that do not have EPDs. It is also worth noting that the decision to use CSEBs as the primary walling material was based on a coefficient of 0.061 kgCO_2e/ kg~1 at concept stage, which is good enough to make major, impactful decisions early on in the project. It is difficult to investigate why the CSEBs made for RICA have 30% less embodied carbon than the generic product in the ICE V2.0 database, because the background information is not provided, but this was one of the reasons we wanted to perform the assessment in the first place.
