The use of collective resources, knowledge, and efforts in pursuit of a goal or set of goals. In politics or economics, collective action is often related to the attainment of public goods and the influence of external factors on group behavior. In sociology, collective action can be used to explain the occurrence of social movements and the factors that cause social integration or nonconformity and conflict. Collective action is also increasingly being linked to climate change. According to the Stern Review, a report produced by the British Government, global collective action is the key to tackle climate change. As the effects of climate change will impact each country differently, joint programs are necessary to tackle the problem as a whole. International collective action to tackle climate change can be facilitated through multinational frameworks, partnerships, networks, and organizations as well as mutual understanding of domestic policy goals.
