Carbon Assessment
USGBC will provide the project team with a 25-year projection of the project’s emissions from operations, refrigerants, and embodied carbon. The assessment will use the data from the following:
-
EAp1: Operational Carbon Projection and Decarbonization Plan
-
EAp5: Fundamental Refrigerant Management
-
MRp2: Quantify and Assess Embodied Carbon
-
LTc4: Transportation Demand Management (optional)
REQUIREMENTS EXPLAINED
This prerequisite requires the project team to conduct a 25-year carbon assessment of all emissions within the project boundary but does not require any additional data to be entered beyond what is already required by the three related prerequisites and the optional credit, if pursued.
Until recently, most projects only considered GHG emissions from operational energy use, if emissions were considered at all. However, as it has become increasingly clear that emissions from construction (“embodied carbon”) and refrigerants can also be quite considerable, LEED v5 has introduced prerequisites which assess carbon emissions from all three sources as well
