One of the primary aims of PaperCut
NG 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." |
