The International Tree Foundation has been protecting and planting trees for over 80 years.

The United Nations Environment Programme (UNEP) has launched a major worldwide tree planting campaign with the objective of planting at least one billion trees worldwide each year.

The Tree Council is the UK's lead charity for trees, promoting their importance in a changing environment.

They plant, protect and promote trees in partnership with local communities.

• 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.
• In the UK only 12% of our land is wooded, compared with an average of 32% in each European country. It's essential we retain wooded areas to help reduce pollution, generate oxygen, maintain wildlife habitats and improve quality of life.

• 1 ton of uncoated virgin (non-recycled) printing and office paper uses 24 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).

  1 ton of coated, lower-end virgin magazine paper (used for news magazines and most catalogs) uses nearly 8 trees (7.68). (Source)

• To calculate how many trees are saved by using recycled paper (1) 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.
