Riassunto: | Human activities have been generating high greenhouse gas emissions (GHG) from two principal sources: fossil fuel used to produce energy and vegetation removal during land use changes and forestry practices. The main GHG are carbon dioxide (CO2), carbon monoxide (CO), clorofluorocarbons (CFC´s), nitrogen oxide (NOx) and methane (CH4). CO2 is the most important GHG, since it has the highest emission rates. The vegetation has the capacity to sequester carbon and incorporate it in their structure and keep it for long periods of time, through photosynthesis, therefore forests are important carbon sink. In the present work the carbon sequestration process and its relation with climate change is described.
