In accordance with the provisions of the 1991 United Nations Economic Commission for Europe Convention on Environmental Impact Assessment in a Transboundary Context (“the Espoo Convention”), transboundary States are required to engage in transboundary consultation, including with members of the public, in respect of projects likely to have significant effects on the environment of neighbouring States as part of the environmental impact assessment of a proposed development. For this purpose, the transboundary State in whose territory the project is intended to be carried out is required to send to the affected State, no later than when informing its own public, a description of the project and any available information on its possible transboundary impact.
