They report that stopping deforestation and allowing young secondary forests to grow back could establish a «forest sink» — an area that absorbs carbon dioxide rather than releasing it into the atmosphere — which by 2100 could grow by over 100 billion metric tons of carbon, about ten times the current annual rate of global fossil fuel emissions.

The Global Footprint Network (GFN) has developed the concepts of biocapacity — the amount of land available to provide for human needs, and ecological footprint — the land needed to satisfy the consumption of different nations in a sustainable manner, including the biological capacity to absorb and mitigate the carbon dioxide emissions that lead to global warming.
