Hi Fei,

On a similar topic, my understanding is that Stage A1-A3 in EN15978 covers the embodied GHG emissions of a product/materials. Can you confirm if my understanding is correct? We can extract the eTool results of Module A1-A3 to quantify the embodied GHG emissions.

Our client is interested in understanding the embodied GHG emissions of concrete and how might we make improvement on the usage of concrete.
