All the actions and means that are able to reduce greenhouse gases (GHG) emissions in the atmosphere and to shrink the extent of global warming. Despite the modest Global Warming Potential (GWP), Carbon Dioxide, for example, is one of the most important GHG due to the level that it has currently been injecting into the atmosphere and the quantity already in it. Humans are able to influence its atmospheric concentration by modifying the use of fossil fuel and by implementing afforestation and reforestation activities. Mitigation strategies may consists in either a reduction in the GHG emissions (as carbon) or in an enhancement of their capture and storage (of carbon). Several ways can be identified for mitigating climate, such as developing new technologies and sciences, reducing demand for emissions-intensive goods and services and enhancing the use of low-carbon technologies, by increasing energy efficiency, switching to cleaner energy sources, and diminishing non-fossil fuel emissions. The mitigation policy of the European Union sets a target on European emissions to maintain the mean world temperature rise within the 2°C with respect to preindustrial levels. This target is normally associated with a concentration of carbon dioxide of 400-500 ppm by volume.
