In concise the concept of global governance provides non-state actors space in the following ways despite the complexities of its own multi-layered and multi-site system.
Beginning with the relation between international relation and global governance, international relation basically defines the politics among nation which includes their individual status, involvement and benefits as well as losses. In a nutshell, it can be derived that there is no room for non-state actors under the domain of international relation. But creating a completely different set of parameters, Global governance provides some very important positions and roles to all sorts of non-state actors namely nongovernmental organizations (NGOs), transnational corporations (TNCs), and scientists. So, we can say that Greenpeace, PETA etc. are functioning actors within the scope of global governance. There are also some other elements similar to non-state actors like civil society and business and science. And as the whole world has now become a single entity under the process of globalization, so governance and global legal order is no longer a political matter involving nations but also those who have got no country affiliation but are basically related to the world and humanity as a whole. Thus, despite being a group of nations, the European Union relied on scientific arguments while taking decisions related to restrictions on trade and commerce of genetically modified organisms. Similarly, the United Nations Food and Agriculture Organization (FAO) is in frequent interaction with experts of agriculture and food. The scientific bodies like the Intergovernmental Panel on Climate Change (IPCC) have been more than instrumental in shaping the legal framework for international as well as national policies. These well described forces of the world have helped in defining better policies of the nation on various critical issues like environment, hygiene, healthcare, pollution etc. Apart from them, there are other non-state actors that forms an intangible part of global governance like the European Commission with interstate jurisdiction. The Dispute Settlement Body of the World Trade Organization (WTO) taking up issues related to trade and commerce between the nations or groups of nations. The global governance in practical sense have been quite inclusive in accommodating non-state actor in the world politics.
As, discussed above, the term international relations basically undertakes measures that enables international interaction under section at a different level to that of social interaction. Extracting similar concepts, global governance derives a multilevel system which includes interlinked structure of processes with local, national, regional, and global variants. The non-state actors are being assimilated into various layers of global governance as equivocally authorized entity which in particular are supposed to guide nations at various situations and also form the link between the layers of global governance. Transnational forums as a non-state actor are legislated into the layers while giving importance to ideas and practices as per national, regional, or local settings and thereby finding solutions to global problems without adding any negligence to local communities and their capabilities.
