Hi all, Wondering how people have been navigating the data collection for A4 emission, and transportation of materials to site. Our projects collect the data from the perspective of the LEED Regional Materials credit, but I expect that has limitations. I’ve been trying to categorize in my mind who …

The answer to this question should interest anyone in Canada whose project received federal Climate Lens funding. We are expected to track these emissions for our projects and report back. From my inquiries, some contractors track this information - not necessarily on every project, but certainly on…

Found this, hope it helps: [image] An analytical method for evaluating and visualizing embodied carbon emissions... Greenhouse gas emissions associated with buildings constitute a large part of global emissions, where building materials and associated processes make… …

The IStructE has a guide for calculating carbon has a very rough estimate for calculating A4 based on mass, distance travelled and method of transport. It’s a useful high level approximation which can indicate how much the transport of material can affect the embodied carbon value. We have found tha…

Hi all, I’m picking this thread up again to see if folks have any direct resources for kg CO2e/ton of material for different transportation modes (rail, truck, ship). I saw some good methodology resources in the links above, but didn’t yet find the emissions factors per mode of transport. I’ll keep…

Jacob, in my searching I found the attached reference. In generally related to shipping, not construction specific, but it’s a start at least. [image] The Green Freight Handbook The Green Freight Handbook was created by Environmental Defense Fund…...

@jmclaughlin I’m not very familiar with the program but EPA’s SmartWay may have some resources to help. [image] SmartWay | US EPA SmartWay is an EPA program that helps the freight transportation sector improve supply chain efficiency. SmartWay reduces transportation-related emissions, e…

Thanks so much for these resources, really helpful! I had found this as well, especially relevant to this thread is their “GHG Emissions from Transport or Mobile Sources” tool: https://ghgprotocol.org/calculation-tools I’m keen to look at the details behind these various resources to understand t…

I’ve also used the Federal LCA commons database in OpenLCA to get transport information as well. GaBi has some good customization options to allow you to look at different transport types and loading rates.
