Most people assume that global warming is caused by burning oil and gas. But in fact between 25 and 30 percent of the greenhouse gases released into the atmosphere each year – 1.6 billion tonnes – is caused by deforestation.

About 200 experts, mostly from developing countries, met in Rome last week to address this issue in a workshop organized by the United Nations Framework Convention on Climate Change (UNFCCC) and hosted by FAO. “We are working to solve two of the key environmental issues – deforestation and global warming – at the same time,” said FAO Senior Forestry Officer Dieter Schoene.

Trees are 50 percent carbon. When they are felled or burned, the C02 they store escapes back into the air. According to FAO figures, some 13 million ha of forests worldwide are lost every year, almost entirely in the tropics. Deforestation remains high in Africa, Latin America and Southeast Asia.
