Forests of the world
Forest cover nearly 40 million km² worldwide, in other words 30% of the earth's land area.

Forest are declining at a rate of 50,000km² annually. This decrease is due to the clearing of tropical rainforest, which is only partly made up by forest expansion elsewhere.

The world's forest are unevenly distributed. The ten most-forested countries contain 2/3 of all forest: Russia, Canada, USA, China, Australia, Republic of Congo, Indonesia, Peru and India

Plant two or three trees per year and become CO₂ neutral.

The average Person is responsible for around 12 tonnes of CO₂ per year. A mature tree, ready for harvesting stores around five tonnes of CO₂. By planting 2 or3 trees a year, the average person can thus lead a CO₂-neutral life if all these trees are allowed to grow to maturity.
In forestry, however, around 20 to 100 times as many trees are planted than actually reach maturity. Most trees are thinned out during the growing process and used for paper, composite products, and CO₂- neutral energy.

1 m³ wood removes two tonnes CO₂ from the atmosphere

When wood is used instead of materials such as steel and concrete the climate benefits in two ways:
1. Around 1 tonne of CO₂ is stored in each cubic meter of wood.
2. A further 1 tonne of CO₂ is saved on average compared with the production processes for a comparable steel or concrete product.

This means that two tonnes of CO₂ are saved when one cubic meter of wood replaces one cubic meter of concrete or steel for use in, for instance, construction.

Finally there is a third benefit to the environment: Once wood products are no longer fit for purpose, they can be burned, thereby utilising there stored solar energy. This replaces the use of coal, oil, and natural gas while resulting in no waste materials.
One tonne of CO₂ is the equivalent of 430 litres of petrol.
