The Energy Star Statement of Energy Performance, which includes the associated on-site emissions, can be generated very easily from the Portfolio Manager website.
Produce documentation of participation in a third-party voluntary reporting program. Your current choices are WRI/WBCSD, Energy Star, or EPA Climate Leaders.
Many waste haulers will provide a breakout of recycled materials by material type upon request, but it is a good idea to check with your hauler to see if they provide this level of detail before implementing your program so that you can create your own process for tracking recyclables if necessary.
If possible, track individual waste stream components that are diverted from the landfill and isolate these values for the purposes of documentation. Ask your waste hauler about providing itemized hauler reports so that you can consistently track the separate waste streams from your building’s ongoing consumables waste, such as paper, cardboard, and glass.
