UNUnited Nations Economic Commission for Europe

Legal Instruments, Norms and Standards - Environment

Since 1979, fourteen international legally binding instruments, five conventions and nine protocols, have been developed in the UNECE on air pollution, environmental impact assessment, industrial accidents, transboundary waters and public participation. These treaties, which are important elements of a common European legal framework, are concrete and effective instruments to eliminate the former dividing line between east and west and to integrate countries with economies in transition into a pan-European legal and economic space.
