Mitigation. In the context of climate change, mitigation is a human intervention to reduce the sources, or enhance the sinks (depositories) of greenhouse gases. Eg., using fossil fuels more efficiently for industrial processes, electricity generation, home heating, etc; switching from the use of fossil fuels to solar energy, wind power, green hydrogen; improving the insulation of buildings; using more efficient mobility vehicles; and expanding forests and other carbon sinks to remove greater amounts of GHGs from the atmosphere.
