Global climate change mitigation is an excellent example of global public good. The two key characteristics of public good namely non excludability and non-rivalry in consumption can be applicable to climate change mitigation. If one country gets benefit from reductions in climate change,

it will not reduce other countries benefit from this reduction. Moreover the mitigation efforts cannot be restricted to a particular nation. If one country puts mitigation efforts then other countries cannot be excluded from enjoying the benefits of these efforts though they do not have any contribution to mitigation efforts. The gains from mitigation efforts provide the benefits to all the countries even to those who have not invested into the abatement policies.

Like other public good, mitigation of GHG is vulnerable to free rider problem.Hence economic of climate change identifies the mitigation of Greenhouse gas as a public good. But the adaptation to climate change is referred to as a private good. This is because it only benefits the country that invests onadaptation. Free rider problem is much more limited in case of adaptation.From the perspective of an individual country, mitigation of green- house emission can be considered as a prisoner’s dilemma game.
