In 1972, the first United Nations Conference on Human Environment (UNCED) was held in Stockholm, Sweden. At the conference, government officials from industrialized and developing nations met alongside civil society organizations to create the United Nations Environment Programme (UNEP). “This conference put environmental issues on the international agenda for the first time, and marked a turning point in the development of international environmental politics. It has also been recognized as the beginning of modern political and public awareness of global environmental issues” (Baylis & Smith, 2005, pp. 454-455). Twenty years later, the United Nations Conference on Environment and Development (UNCED), also known as the Rio Earth Summit, was held in Rio de Janeiro. One hundred and seventy two government officials participated, of which 108 were heads of state (United Nations, 1992, United Nations Conference on Environment and Development, para. 1). This conference was one of the largest gatherings of heads of state, civil society organizations, and individuals in human history to date. Stakeholders met with the purpose of charting a course for a more sustainable future. From the conference emerged agreements, most notably Agenda 21, which created a framework for developing global, national, and regional plans for sustainability. The Rio Earth Summit has since stood as an example of what is possible when governments and citizens work together. The outcomes of this conference still affect human lives today, mainly through the United Nations Framework Convention on Climate Change meetings, which led to the Kyoto Protocol, the only legally binding agreement to cut down carbon dioxide (CO₂) emissions. The United Nations Conference on Sustainable Development, also known as Earth Summit 2012 or Rio+20, is regarded as one of the most crucial events in United Nations history and has been referred to by the Secretary General of the United Nations (2011), Ban Ki-moon, as “the most important global meeting on sustainable development in our time" (The Future We Want, p 2).
