Dear EarthTalk:

I want to convince my high school to go green. What would it cost for a
school to switch to all recycled paper products and all energy efficient
lighting?—Danel Berman, via e-mail

Greening your school is a great idea. It will not only benefit the
environment but the student body as well. According to the “Greening
America’s Schools” report, sponsored in part by the non-profit U.S. Green
Building Council (USGBC), green buildings provide a better study and
learning environment for students. Improved lighting, air quality and
acoustics are estimated to improve learning abilities and test scores by
as much as five percent. And what better way to teach young people about
the importance of environmental stewardship than starting right in the
schools where they spend the majority of every weekday?

Since every school is different, there is no universal formula for
calculating how much money going green will cost. Switching over to
recycled paper, for instance, will not necessarily be cheap. A recent
spot-check at a national office supply chain showed that the price for a
ream (500 sheets) of 30 percent recycled copy paper was 20 percent higher
than a ream with no recycled content. If you chose 100 percent recycled
content, you would pay 35 percent more per ream. But prices can vary
widely depending upon where you buy paper, and bulk purchasers like
schools may be able to negotiate much better prices.

The best way to offset the added costs of switching to recycled paper is
to cut paper usage at the same time. Start a program to educate students
about how they can reduce paper waste by printing on both sides of a sheet
and by not printing as many drafts, for example. You can also encourage
your school to switch to e-newsletters instead of paper ones and find
other ways to reduce administrative paper use.

Switching to recycled paper is definitely a big win for the environment.
The Natural Resources Defense Council (NRDC) reports that 40 cases of 30
percent recycled copy paper (400 reams) will save more than seven trees,
2,100 gallons of water, 1,230 kilowatt-hours of electricity and 18 pounds
of air pollution.

You can calculate this impact for your school. Ask your school purchaser
how much printer/copier paper is purchased, and calculate its weight in
pounds or tons. Then go to the Environmental Defense Fund’s online Paper
Calculator. Enter the weight and type of paper you use and you can
determine the amount of wood, energy, water, solid waste and greenhouse
gas emissions you’ll save by switching to recycled.

As for lighting, many schools already use a lot of fluorescent lighting.
If your school still uses incandescent bulbs, consider that for every
60-watt incandescent bulb switched to a 13-watt compact fluorescent, the
school could save 75 percent in energy use—an average of $45 over the life
of each bulb.

Ambitious schools can also put in occupancy sensors that turn lights off
when rooms are vacant, or install task lighting to further reduce energy
usage. Such add-ons might seem like luxuries for already strapped schools,
but it just may be worthwhile anyway given the energy that can be saved
and the lessons learned.
