What the international environmental law is lacking in the year of its 175th anniversary?

The article deals with the analysis of the branch signs of the international environmental law. It is concluded that for the 175 years of its existence, international environmental law has not managed to adopt a wide universal codifying international legal act, systematizing principles of this special set of international legal norms. It is proved that today the most complete on the list of special principles of international environmental law is the 2010 Draft Covenant on Environment and Development, which describes the content of nine such principles. It is proved that today one more special principle of international environmental law is coming to life - the principle of the conservation and sustainable use of biodiversity. On this fact is an indication in the art. 2 and art. 25 of the Draft Covenant. It is proposed that Russian diplomacy has focused its efforts on further improving the Draft Covenant, on clarifying the concept and terminological apparatus of this document, which is subsequently to be adopted either as a UN General Assembly resolution, or at a specially convened international conference ad hoc.
