I recently gave a presentation summarizing how biogenic carbon of wood products are accounted for in Whole Building Life Cycle Assessments (WB-LCA). In that presentation, I discussed a dynamic approach to modelling biogenic carbon called “GWPbio”, which can account for factors such as forest rotation period and product carbon storage period. This is one way of quantifying the difference in climate benefit between incinerating wood (storage period = 0 years) and storing it in a building (storage period = building lifespan, which we might assume to be 60 years in WB-LCA).
Here are my slides from that presentation:
WWF and Quantis recently released a great Excel tool for quantifying these GWPbio factors. In my presentation, I showed a few preliminary scenarios that I modelled, including using wood in buildings and for bioenergy.
Hope this helps!
Cheers,
