GHG emission factors are automatically pulled into the spreadsheet as determined by the disposal
method. If this cell is left blank, the emission factors will not update and emissions will not be calculated.
Emissions calculations for each GHG (CH
4
,
and N
2
O) are completed in the blue shaded cells. The total
carbon dioxide equivalent (CO
2
-
eq) in metric tons of the GHGs is output in the final column.
City-Owned Landfill Operations
Landfill with a Cap and Landfill Gas (LFG) Recovery System
Department
Enter the department for which data is being entered.
Facility Name
Enter the name of the active landfill at which municipal solid waste
(
MSW) is disposed and/or that has a landfill gas (LFG) recovery system.
NOTE: Some closed landfills operate LFG recovery systems.
Landfill Cover Type
Select the type of landfill cover from the drop-down list. This selection will
determine the oxidation factor.
Control Device
Select the recovery system control device type from the drop-down list.
This selection will determine the system destruction efficiency.
Landfill Gas Generated
Enter the annual amount of LFG generated as determined by the USEPA
Landfill Gas Emissions Model (LandGEM).
NOTE: Data should be
entered in ft
3
/
min.
Landfill Gas Collected
Enter the annual amount of LFG collected by the recovery system.
NOTE: Data should be entered in ft
3
/
min.
Methane Content
Enter the methane content of the LFG collected.
Methane Flow Collected
The total methane gas collected is determined based upon the methane
content of the LFG collected.
Collection Efficiency
The system collection efficiency is calculated using the values for the
total LFG generated and collected.
Percent Equity
Enter the percent ownership of the asset being considered – city-owned
assets should be listed as having 100% equity.
GHG emissions are determined by the landfill cover and control device type. If these cells are left blank,
emissions will not be calculated. Emissions calculations for each GHG (CO

Landfill without a Cap and Landfill Gas (LFG) Recovery System
Department
Enter the department for which data is being entered.
Facility Name
Enter the name of the active landfill at which municipal solid waste (MSW) is
disposed.
Material
Choose the type of wastes disposed using the drop-down list. Complete
individual entries for each material disposed at the landfill.
Quantity to Landfill
Enter the annual quantity of wastes sent to the landfill.
Quantity Incinerated
Enter the annual quantity of wastes sent to the incinerator at the landfill, if
applicable.
Quantity Composted
Enter the annual quantity of wastes composted at the landfill, if applicable.
