The Convention on Environmental Impact Assessment in a Transboundary Context (informally called the Espoo Convention) is a United Nations Economic Commission for Europe (UNECE) convention signed in Espoo, Finland, in 1991 that entered into force in 1997.
As of August 2011, Hrvatske autoceste and Autocesta Rijeka - Zagreb operators of the A1 motorway signposted the A1 south of Karlovac as the E71 all the way south to the Dugopolje interchange connecting to the Podi interchange of the D1, contrary to the United Nations Economic Commission for Europe (UNECE) specification of the route.
Among these are the United Nations Economic Commission for Europe (UNECE) and its Centre for Trade Facilitation and Electronic Business (UN/CEFACT), World Customs Organisation (WCO), SITPRO Limited of the United Kingdom and the Association of Southeast Asian Nations (ASEAN).
See for example the UNECE Espoo Convention, Aarhus Convention, Convention on Long-Range Transboundary Air Pollution and Convention on the Transboundary Effects of Industrial Accidents.
It should be noted, however, that the impending Comprehensive Economic and Trade Agreement between Canada and the European Union (likely to be ratified in 2015) will see Canada apply all of the provisions of UNECE standards as 'allowable alternatives' to the CMVSS standards; Canada currently applies 14 of the 17 ECE main standards as allowable alternatives - the exceptions at this point relate to motorcycle controls and displays, motorcycle mirrors, and electronic stability control for passenger cars.
