Mitigation

An intervention to reduce anthropogenic (i.e. human-induced) sources of greenhouse gas emissions, or increase the capacity of carbon sinks through e.g. reforestation. Mitigation means dealing with the direct roots or causes of climate change by reducing GHG emissions compared to dealing with the unavoidable impacts of climate change (see Adaptation). Examples of mitigation measures include switching to low-carbon energy sources, such as renewables and nuclear energy, and expanding forests and other "carbon sinks" to remove larger amounts of carbon dioxide from the Earth's atmosphere. Energy efficiency can also play a role, e.g. through improving the insulation of buildings, or reducing energy use of older equipment, as well as changing management practices and consumer behavior. Replacing fossil fuel driven vehicles with electric ones is another.
