After the consideration of these critical issues, the concept of common interest was designed.
Common interest refers to a monumental step that was taken by countries to undertake collective responsibility in addressing the global warming due to increasing in industrial emissions to the atmosphere. Notably, there has been a number of international fora have tried to bring together nations to address this challenge. Vasser (2009 states that the 1992 United Nations Framework Convention on Climate Change (UNFCCC) and the 1997 Kyoto Protocol came up with international obligations from each member state that would see the greenhouse gases reduce (Khare 2013). They laid down the framework for cooperation in militating against the adverse environmental pollution. Moreover, they admitted that they had different national issues to pursue, but the greenhouse effect was a unifying issue hence the shared but differentiated responsibility (Rabe 2010).
One of the primary agreements was dubbed "Clean Development Mechanism" (CDM) and establishment of Green Climate Fund (GCF). Both were to lay the ground for the promotion of development free of air pollution. Besides, the nations undertook shared responsibility under the policy of CDM to reduce industrial emissions as the number priority of a healthy environment. Besides, GCF was to be channeled to developing countries to help reduce the effects of industrial emissions.
Despite aggressive government to adopt legally binding policies to mitigate on the climate change, the developed countries continue to emit harmful gases. Notably, United Kingdom and recently China continued to emit undesirable levels of industrial gases to the atmosphere (LeoÌ 2008). Sadly, the notion that the developed countries would spearhead climate rehabilitation is quite misleading. The United States and its proponents on climate continue to mislead other nations in the pretext
