I’m developing the reduction target for scope 3 emissions for our company, and especially in setting a target related to embodied carbon intensity (which is a key item in our plan). However, we have encountered some challenges and I’m trying to work our way through the following questions:
- How to choose the format of the embodied carbon intensity baseline - should it be on a project basis or portfolio basis? Our company has developing projects in different areas, so there are pros and cons either way.
- If we choose a project-based embodied carbon intensity target, how should we decide on the baseline and comparison stages (e.g., design in tendering stage, schematic design stage, detail design stage, or even construction stage)? For now, we are thinking of comparing the building information in tendering stage with detail design stage, but we are not sure if there is a recent standard or practice addressing this issue, or if CLF has guidance on this matter.
- If we choose a portfolio-based target, I understand CLF and RICS have study on embodied carbon benchmarks for different project types. However, the benchmarks are normally shown in a range instead of a specific number. Is it possible to set a specific number for the whole portfolio baseline? Does anyone know if there is are recent studies or discussions on this topic?
Thank you all and I’d be grateful if anyone would have some recommendations or thoughts.
