One of the primary aims of PaperCut
is to reduce printing levels by changing a user's
printing behavior. Implementing monitoring, quotas
and charging are a good way of drawing a user's
attention to their habits. The topic of the environment,
global warming, and waste management is currently
an area of debate and interest to many. Highlighting
the environmental aspects of their activities
is another good way of modifying a user's behavior.

The Environmental Impact section is available
to end-users via their web summary page . Administrators
also can view the impact of a user and a printer
via the details pages in the admin interface.
- Trees: The percentage of
a tree (or trees) used to make the paper.
- Carbon: The amount of CO2
(green house gas equivalent) that was released
in the process of manufacturing and delivering
the paper.
- Energy: Represents the impact
in terms of the equivalent impact of running
a 60W bulb for a period of time.

Trees
|
This value corresponds to percentage of a tree
that has gone into making the paper. The value assumes
the user is printing on standard A4 or Letter sheets
and 80,500 sheets make up a tree [a]
This value is set by the config key: environment.sheets-per-tree
|
Carbon
|
This value corresponds to greenhouse gases released
in the production of the paper (CO2 equivalent).
The value assumes that the user is printing on standard
A4 or Letter sheets and one sheet equals 8.6g CO2
[b].
The default value takes in account CO2 produced
as a byproduct of the paper production only. It
does not take into account the power consumed
by the printer or power associated with the ink
/ toner use and production. Finding referenced
figures on these values is difficult, and one
could argue that the printer power consumption
is not a function of the user's usage as the printer
would be there consuming power even if they choose
not to use the device.
This value is set by the config key: environment.co2-grams-per-sheet
|
Energy
|
This value represents the manufacturing energy
used to produce the paper. The energy value is represented
by relating it to the equivalent energy consumed
by a standard light bulb. This provides users with
a real world understanding of the value. This value
assumes the user is printing a standard A4 or Letter
sheet and that the manufacturing cost per sheet
is 17Wh [c]. This is an appropriate amount for virgin
office paper. 12Wh is more appropriate for 100%
recycled paper [d].
This value is set by the config key: environment.watt-hours-per-sheet

| "Well done
on producing the best print charging solution I
have used! PaperCut is fast, reliable and easy to
manage. The advanced charging options provide excellent
flexibility and the web administration interface
is the icing on the cake." |
