5. On the Product Data Sheet, record the usage ofenvironmental impact factors associated with theremoval per year of the operation of this system.
The usage of environmental impact factors shallbe calculated using the following formula:

Wy = ∑zWy,zFz

Wy: the usage of environmental impact factors
per yearWy,z: the usage of environmental impact factors
associated with the installation ofequipment type "z":theduration (years) of use for equipmentFztype "z"Use the actual number of years of use or thenumber of legal durable years for "Fz." Apply
the same values used for the servers to the racks.
6. The scenario regarding the disposal and recyclingof this system is as follows [Appendix 2]:• Upon disposal, all equipment comprising thissystem is disposed of as industrial waste.
• Each piece of equipment is transported from theInternet data center to the intermediary disposal
company, where it is shredded and sorted.
99% of the gas used for air-conditioning is
destroyed for disposal and 1% leaks into the air.
80% of the metals are reused as materials andthe remaining 20% is sent to the landfill.
100% of all other items than metals or gas used
for air-conditioning are disposed of in thelandfill.
• The means of transportation from the Internet
data center to the intermediary disposal
company is 10-ton truck with single(unconsolidated) cargo, and the transportation
distance is 100 km.
7. Only the metals reused based on theaforementioned disposal and recycling scenario
shall be factored into the deduction related to thedisposal and recycling of this system.
8. The reuse of products and parts composing eachpiece of equipment in association with thedisposal and recycling process is not considered.

9. On the Product Data Sheet, record the amount of
items disposed or recycled per year of theoperation of this system. The disposed/recycled
amount shall be calculated using the following
formula:Wd ,q = ∑z

Wq , zFz

Wd,q: the amount of item type "q" disposed or
recycled per year
Wq,z: the amount of item type "q" disposed orrecycled, which is related to equipment type"z":

raw material manufacturing. Apply corresponding
common unit functions for processing whencalculating the impact of the manufacturing of parts.
When these parts or equipment are assembled,calculate the impact using the common unit function
specified for assembly.
Not specified; each company shall add categories asnecessary.
Not unified; each company shall decide as it sees fit.
1. The location of data collection is the Internet datacenter.
