The CO2 Emission Calculation Tool can be used to calculate CO2 emissions from secondary energy sources typically used in commercial buildings, including chilled water, steam and electricity. It outputs CO2 emission values based on energy consumption values or energy cost values. This tool will convert different energy units automatically.
