The United Nations Conference on Environment and Development (Earth Summit) held in Rio de Janeiro in June 1992 was an undisputed milestone in environment protection and management. The ambitious target to achieve by 2010, a significant re - duction in the current rate of biodiversity loss at the global, regional and national level, was not met. In October 2010, the Parties to the Convention on Biological Diversity adopted a revised and updated Strategic Plan for Biodiversity for 2011–20. The forthcoming UN Conference on Sustai - nable Development is going to aim particularly at the Green Economy in the context of sustainable development and poverty eradication. and Jan Plesník.
