Bulgaria signed the Aarhus Convention at its inauguration in 1998 during the Fourth Summit “Environment and Earth.” The Convention was ratified by the Parliament on 2nd October 2003 and took effect on 16th March 2004. By the enactment, Bulgaria stood for Partnership for Principle 10, which is planned and coordinated by the global coalition of public organizations—the Access Initiative of the World Resource Institute . In order to provide the efficiency of the public groups, which observe the application of the Rio Declaration principles in different countries, The Access Initiative has developed a common methodology for the estimation of the existing situation. On the basis of that evaluation, suggestions for the improvement of the access to information situation, the conditions of public participation, and the access to justice on environmental issues have been made.
