I have a project that wishes to use CLT slabs and have been comparing the LCI data to general EPDs for CLT products.
I notice that EPDs generally assume the timber product is chipped and incinerated during module C and the carbon sequestered is released back into the atmosphere (this giving a +ve GWP over modules A-C) whereas the LCI data in eTool (IMPACT and eTool defualt) does not seem to make this assumption (the GWP over modules A-C remains -ve). Could you therefore give me an idea of what module C is accounting for in timber products in the LCI databases, such as just removing the timber and taking it to landfill with no release of sequestered carbon?
