It should not come as any great surprise that choosing the right paper can save wood, water and energy and cut pollution and solid waste. Conservatree offers a one-stop shop for information on environmental papers for both small-scale paper and experienced, large-scale purchasers. Since almost every business makes purchases of copy paper having a listing of specific brands of paper, their environmental information and availability can be very helpful.
Many paper companies we reviewed had excellent information on their "eco-brands." Several had calculators to help you determine the impact of choosing one brand over another. Or, choosing a lighter weight paper for a project.
One research project regarding changing just the margins on paper revealed a number of amazing statistics.
According to a study done by the Penn State Green Destiny Council, reducing margins to .75" on all sides results in a total reduction of paper by 4.75%. This means that using these Efficient Margins on a ton of paper saves 19 reams of paper, which saves 1.14 trees.
This calculation is based on the following stats from Conservatree:
-1 ton of uncoated virgin (non-recycled) 20# printing and office paper uses 24 trees.
-1 ream of paper (500 sheets) uses 6% of a tree.
-1 tree makes 16.67 reams of copy paper or 8,333.3 sheets
-The trees that are being used to make the paper are a mix of 40 foot-tall hardwoods and softwoods, 6-8" in diameter.
So, you ask, what's the big deal? 1.14 trees don't seem like much of a tree-savings for a whole ton of paper. Check these numbers out - they add up fast:
In 2003, the U.S. consumed approx. 5.4 million tons of office paper. If everyone used Efficient Margins, every year we would save 6,156,000 trees.
Here's how you get that figure:
(5.4 million tons) x (Efficient Margins saving factor of .0475) x (24 trees/ton) = 6,156,000 trees
And by reducing the amount of extra paper we'd have to create, we'd save a lot in energy costs and waste products, too...
-Total energy: 9,840,368 million British thermal units (Btus), which is enough to provide power to 108,136 homes
-Greenhouse gas emissions: 1,459,535,366 pounds, which is the equivalent of CO2 emissions from 132,528 cars
-Solid waste: 584,396,539 lbs, which is the equivalent of 20,871 fully loaded garbage trucks
-Wastewater: 4.8 billion gallons, which is enough to fill 7,408 Olympic-sized swimming pools
Suddenly, one little margin change feels like it has a lot more impact!
