Which of the following LEED credit data should be used for a comprehensive 25-year carbon-emissions...

Data from EAp5: Fundamental Refrigerant Management is relevant because refrigerant leakage can be a significant source of direct greenhouse-gas emissions during a building’s operating life. A comprehensive 25-year carbon projection must consider more than electricity and fuel consumption; it must also account for refrigerant type, charge, global warming potential, anticipated leakage, equipment replacement, and end-of-life recovery. WEp1 concerns water consumption and metering rather than direct operational carbon emissions. MRc4 addresses product selection and procurement and is more closely associated with material disclosure and embodied impacts than with the building’s long-term operational emissions forecast. LEED v5 specifically expands decarbonization to cover operational, embodied, refrigerant, and transportation emissions, making refrigerant-management data necessary for a comprehensive projection.
