role of international organisation

Common access resources like private goods are rivalrous but like public goods are non excludable. Thus common access resources are consumed without any payment, giving rise to a significant decrease in environmental stability. The depletion of common access resources leads to negative externalities, like the smog in Beijing and Delhi. This is why common access resources is a form of market failure.

Sustainability has become a recurring problem in the world today, it's meaning refers to preserving common access resources over time. The economy strives to improve their output while environmental goals consist of preserving the environment, to prevent the depletion of resources.

'The role of international organisation' is a solution to common access resources, as no one 'owns' these common access resources no country can be solely blamed for the depletion of these resources. An example of a common access resource is the ozone layer, at this point in time, china is the world's most polluting country. But, all governments can't expect china to solely make an effort in preserving the environment, as all countries have contributed to the depredation of the ozone layer.

Therefore, an initiative to protecting the environment has to be made. The Montreal protocol, Kyoto Protocol, EU ETS, and more recently the Paris summit, are examples of methods to preserve the environment. The montreal protocol has been the most successful one while the Paris summit of 2015 is the most recent one. It focuses on capping the world temperature and making sure it doesn't increase by more than 2 degrees. 196 countries have signed a new agreement for tackling climate change with long term approaches. 

Therefore, the role of international organisations is to foster cooperation between all governments, of the world, to consolidate a foolproof plan to save the world, and preserve common access resources.
