Everybody stands to gain when countries adopt common international legal instruments and standards and harmonize their technical regulations. Consumers can be confident that they are buying products that live up to guaranteed quality standards. Citizens can more easily trade and travel across borders. Companies can more efficiently innovate, invest and streamline their production and sales when they no longer have to adapt to a multitude of national rules and regulations. International trade is facilitated when sellers and buyers use common classifications, documents and trade procedures.

International legally binding conventions can help to protect common goods such as water resources or to avoid air pollution. National legislative and regulatory work is simplified and accelerated when reference can be made to internationally agreed documents. Indeed, when countries develop and share common norms, standards and conventions, it facilitates their cooperation and connectivity, and this can pave the way for progress and peaceful coexistence.

Member countries of the United Nations Economic Commission for Europe (UNECE) realized this from the outset. Their common efforts, now for nearly seventy years, have resulted in a wealth of conventions, harmonized technical regulations, norms and standards. Virtually all of the Commission’s subsidiary bodies have contributed in one way or another to their elaboration. I thank all Government officials and experts who have participated in the work on developing and updating these instruments for their dedication and commitment through the years.

Studies have shown that many of UNECE’s agreements on technical and/or procedural harmonization are being effectively implemented.  The attached list of conventions, norms and standards, which have been negotiated under the auspices of the UNECE, has been compiled in order to facilitate wider access to this valuable body of information.
