Earth Day is on 22 April each year. Their mission is to broaden and diversify the environmental movement worldwide, and to mobilize it as the most effective vehicle for promoting a healthy, sustainable environment. They pursue their mission through a combination of education, public policy, and consumer activism campaigns.

Choose What You Read is a reaction to the thousands of free newspapers given out every day to commutors and thrown away. This is an opportunity to read a book instead, donated by the public.

Are you a 'Competitive Printer', and 'Old School Printer' or a Pedestal Printer?

• A single tree will absorb approx 730kg of CO2 over its lifetime
• One person causes about 10 tonnes of carbon dioxide to be emitted a year. One tree removes about 3/4 of a tonne of CO2 over its lifetime.
• By cooling the air and ground around them, the shade from trees helps cool the earth's temperature.
• A single mature beech tree can produce enough oxygen for 10 people in a year.
• Trees renew our air supply by absorbing carbon dioxide and producing oxygen.
• Shade trees can make buildings up to 20 degrees cooler in the summer.
• Trees lower air temperature by evaporating water in their leaves.
• Tree roots stabilize soil and prevent erosion.
• Trees improve water quality by slowing and filtering rain water, as well as protecting aquifers and watersheds.
• Over one given year; one hectare of mature woodland will absorb the carbon emissions of 100 average family cars.
• It is estimated that the average person in the UK consumes the equivalent of 12 trees a year. This present rate of world consumption is unsustainable and yet trees are vital to our life on earth.
• How many trees:
• 1 ton of 100% virgin (non-recycled) newsprint uses 12 trees
  A "pallet" of copier paper (20-lb. sheet weight, or 20#) contains 40 cartons and weighs 1 ton. Therefore, 1 carton (10 reams) of 100% virgin copier paper uses 0.6 trees
  1 tree makes 16.67 reams of copy paper or 8,333.3 sheets
  1 ream (500 sheets) uses 6% of a tree
  1 ton of coated, higher-end virgin magazine paper (used for magazines like National Geographic and many others) uses a little more than 15 trees (15.36 trees)
  1 ton of coated, lower-end virgin magazine paper (used for newsmagazines and most catalogs) uses nearly 8 trees (7.68 trees)
• To calculate how many trees are saved by using recycled paper  Multiply the number of trees needed to make a ton of the kind of paper you're talking about (groundwood or freesheet) by the percent recycled content in the paper. For example, 1 ton (40 cartons) of 30% postconsumer content copier paper saves 7.2 trees. 1 ton of 50% postconsumer content copier paper saves 12 trees.
• Other tips for environmentally friendly office use:
  - Refill and reuse empty printer cartridges
  - Use rewriteable CDs and DVDs so they can be re-used again
  - Print double-sided.
  - Decrease margin areas to fit more copy on a page
  - Double-check your drafts before you print
  - Communicate with team members about who will bring printouts to meetings
  - Turn off all electrical equipment at night.
• Paper consumption has tripled in the last decade.
• Every year, the United States uses nearly 3.7 million tons of copy paper - more than 700 billion sheets.
