European citizens will find out about sources of pollution in their neighbourhoods soon according to an international agreement,?UN?said?in Geneva Friday.

As the first-ever legally binding pact on pollutants, Kiev Protocol requires countries to publicly report every year the amounts of certain types of pollutants, such as greenhouse gases or heavy metals, chemical plants, power stations, oil and gas refineries, mines and waste plants.

"It will enable ordinary citizens, simply using the Internet, to find out about the major sources of polluting emissions in their immediate neighbourhoods," said Ján Kubi?, executive secretary of the UN Economic Commission for Europe (UNECE).

"The Protocol establishes a new international benchmark in securing public access to information on threats posed to our environment by toxic emissions," he added.

The 2003 Kiev Protocol on Pollutant Release and Transfer Registers (PRTR) entered into force last October, and currently, 23 countries and the European Union are parties to it.

The Protocol is part of the so-called UNECE Aarhus Convention, or the Convention on Access to Information, Public Participation in Decision-making and Access to Justice in Environmental Matters, which entered into force in October 2001.
