We all know of the need to print important documents, assignments, research and other things. However, have you ever stopped to think how many times you printed something unnecessary that after a few days you did not use anymore?

-       Paper and paper products accounts for more than 1/3 of all Canada’s waste.

-       Canada uses 6 million tons of paper and paperboard annually. Only 1/4 of Canada’s waste paper and paperboard is recycled.

-       Approx. 324 L. of water is used to produce 2.25 pounds of paper.


-       As many as 24 trees are required to make one ton of paper.

-       Global paper use has grown more than six-fold since 1950. One fifth of all wood harvested in the world ends up in paper. Pulp and paper is the 5th largest industrial consumer of energy in the world, using as much power to produce a ton of product as the iron and steel industry. In some countries paper accounts for nearly 40 percent of all municipal solid waste.

-       Average worldwide annual paper consumption is 48 KG per person.


After read these information, what about think before you print in the next time? Besides the number, I bet you had not thought of how much energy is spending in papermaking. Manufacturing paper requires energy. That paper starts as a tree. The tree gets harvested, transported some distance to a plant to get sliced up into chips. Those wood chips are then transported to a pulp mill, which can be thousands of miles away. At the pulp mill, the wood chips are ground into pulp, which gets bleached and washed and sent to the paper mill to be made into paper. Eventually, the paper is cut into the right size sheets for your laser printer, packaged, and then shipped — again, maybe thousands of miles — to your local office store.

The Challenge and CO2 emission
As each ream (500 sheets) of copy paper used is responsible for 30.5 pounds of released CO2 reducing your use of paper by just one quarter during 1 month will save 7.6 pounds pf CO2.
Remember, recycling is good but reducing the amount of paper you use to begin with is even better. You’ll save money and reduce carbon.

What changes we can do:
Reduce
·         Only print what's necessary.
·         Make the point size smaller in your documents to reduce the number of printouts.
·         Send people PDFs instead of printouts.
·         Don't overprint: find out how many people need to receive what you are sending out.
·         If you are printing a document to review, edit, or make comments, make them on-screen instead. You can do this with the “Track changes” and “Insert comments” features in Microsoft Word. Speaking of Word, another way to get more words on a page (and therefore use less paper when you finally print) is to decrease your font size and change Word’s “generous” default margins so that there isn’t as much white space surrounding your text.
·         If you really have to print, do it on both sides of the paper.
·         Some printers have a booklet setting which prints two-up pages on both sides of the paper, effectively giving you four on one sheet of paper- a 75% reduction.
Reuse
·         Use the other side of printed sheets when documents are drafts, so you can make notes, for example. Once you`ve used both sides of the paper, then you can recycled it.
·         Cut scraps of paper and use them as notes.
·         Donate your old books, trade and consumer magazines to your local library.
Recycle

·      Recycling saves 3 to 5 times the energy generated by waste-to-energy plants, even without counting the wasted energy in the burned materials.
Making a ton of paper from recycled paper saves up to 17 trees and uses 50 percent less water than does creating paper from virgin pulp
·         Recycling 1 ton of mixed paper saves the energy equivalent of 185 gallons of gasoline
·         Recycling 54 KG of newspaper will save one tree.


Global consumption of wood fiber for papermaking can be cut by more than 50 percent, reports a new study by the Worldwatch Institute. This reduction can be achieved through a combination of trimming paper consumption in industrial countries, improving papermaking efficiency, and expanding the use of recycled and nonwood materials, according to Janet Abramovitz and Ashley Mattoon, co-authors of Paper Cuts: Recovering the Paper Landscape
