As part of the FP6 Program, a project named WEB-ENV 'Development of environ- mental guidelines for the region of Western Balkans' dealt with the state of the environment in the region of the West Balkan countries: Albania, Bosnia and Herzegovina, Croatia, FYR Macedonia, Montenegro, and Serbia. The parameters which were observed were air and water quality, solid waste pollution, soil degradation, and state of biodiversity. The results are presented as an extended mapping exercise identifying major environmental problems in each country. This paper outlines the comparative analysis of the parameters observed in the project and their respective resources. This paper also presents the impact of some polluters on the environmental condition of the countries surrounding Western Balkans. The analysis of data proves that certain areas have insufficient parameters especially in the field of ground water quality and soil degradation. Another problem in the comparative analysis was discrepancy of year of data collection. In order to get a better understanding of the environmental issue in the region it has been determined that it is necessary to provide comprehensive data monitoring via regional projects on the territory of the Western Balkans.
