Climate change mitigation is action to decrease the intensity of radiative forcing in order to reduce the potential effects of global warming. Mitigation is distinguished from adaptation to global warming, which involves acting to tolerate the effects of global warming. Most often, climate change mitigation scenarios involve reductions in the concentrations of greenhouse gases, either by reducing their sources or by increasing their sinks.

- Climate change mitigation is action to decrease the intensity of radiative forcing in order to reduce the potential effects of global warming. Mitigation is distinguished from adaptation to global warming, which involves acting to tolerate the effects of global warming. Most often, climate change mitigation scenarios involve reductions in the concentrations of greenhouse gases, either by reducing their sources or by increasing their sinks. The UN defines mitigation in the context of climate change, as a human intervention to reduce the sources or enhance the sinks of greenhouse gases. Examples include using fossil fuels more efficiently for industrial processes or electricity generation, switching to renewable energy, improving the insulation of buildings, and expanding forests and other "sinks" to remove greater amounts of carbon dioxide from the atmosphere. Scientific consensus on global warming, together with the precautionary principle and the fear of abrupt climate change is leading to increased effort to develop new technologies and sciences and carefully manage others in an attempt to mitigate global warming. Most means of mitigation appear effective only for preventing further warming, not at reversing existing warming. The Stern Review identifies several ways of mitigating climate change. These include reducing demand for emissions-intensive goods and services, increasing efficiency gains, increasing use and development of low-carbon technologies, and reducing fossil fuel emissions. The energy policy of the European Union has set a target of limiting the global temperature rise to 2 °C compared to preindustrial levels, of which 0.8 °C has already taken place and another 0.5–0.7 °C is already committed. The 2 °C rise is typically associated in climate models with a carbon dioxide equivalent concentration of 400–500 ppm by volume; the current (April 2011) level of carbon dioxide alone is 393 ppm by volume, and rising at 1-3 ppm annually. Hence, to avoid a very likely breach of the 2 °C target, CO2 levels would have to be stabilised very soon; this is generally regarded as unlikely, based on current programs in place to date. The importance of change is illustrated by the fact that world economic energy efficiency is presently improving at only half the rate of world economic growth.
- La mitigación del cambio climático es la acción que consiste en disminuir la intensidad del forzante radiativo con el fin de reducir los efectos potenciales del calentamiento global. La mitigación se distingue de la adaptación, que implica actuar para minimizar los efectos del calentamiento global. Muy a menudo, la mitigación supone la reducción de las concentraciones de gases de efecto invernadero, ya sea mediante la reducción de sus fuentes o aumentando su almacenamiento.
- Ilmastonmuutoksen hillitseminen on ilmaston lämpenemisen ehkäisemistä siitä aiheutuvien seurausten vähentämiseksi. Haitallisia seurauksia voidaan vähentää myös ilmastonmuutokseen sopeutumisella, jolla tarkoitetaan varautumista odotettavissa oleviin muutoksiin. Ilmastonmuutosta pyritään hillitsemään yleensä kasvihuonekaasupäästöjä vähentämällä. Ilmastonmuutoksen hillitseminen olisi periaatteessa mahdollista myös muun muassa vaikuttamalla maapallon albedoon tai poistamalla kasvihuonekaasuja ilmakehästä. Näitä keinoja ei suosita niiden epävarmuuden ja/tai kalleuden vuoksi. Kasvihuonekaasupäästöjä voidaan vähentää erilaisin keinoin, jotka kohdistuvat energiantuotantoon ja -kulutukseen energiatehokkuuden tai energiansäästön keinoin, sekä vaikuttamalla liikenteeseen, rakentamiseen, teollisuuteen, maa- ja metsätalouteen sekä jätehuoltoon.
