AO MOSENERGO summarized the air protection efforts taken during seven months of 2004. As a result of environmental measures and lower use of hard fuel and fuel oil, the Company has considerably reduced air pollution.

During seven months of 2004, AO MOSENERGO has cut the use of fuel against last year’s numbers by 5.4%. In addition, the technical impact on the environment was lowered due to a series of environmental measures at AO MOSENERGO: the installation of new equipment and advanced technologies. AO MOSENERGO is carrying out a long-term environmental program of the Moscow Government which lasts until 2010. In particular, the company has been installing low-toxic burners, liquid fuel treatment systems and other equipment that complies with higher environmental standards.

As a result, during seven months of 2004, the total emission by all AO MOSENERGO’s electric power stations fell almost 14.5%, and by more than 25% at CHPs.

Environmental protection is AO MOSENERGO’s top priority. The share of natural gas in AO MOSENERGO’s fuel balance remains high which helps reduce polluting emissions. During last ten years AO MOSENERGO has never exceeded existing environmental requirements.
