ENVIROMENTAL KUZNETS CURVE - A TIE BETWEEN ENVIROMENTAL QUALITY AND ECONOMIC PROSPERITY.

The goal of the article is an introduction of Environmental Kuznets Curve as a concept, discu-ssion of its existence arising from empirical research for different pollutants and its theoretical explanation. The article includes own EKC research result concerning particulate matter in the air. Economic growth, measured as GDP per capita in a given country, is connected with increasing pollution, but after some turning point pollution starts declining. This relationship has an inverted U-shape and is called Environmental Kuznets Curve (EKC). EKC was first identified in a research by Grossman and Krueger from 1991 [8], other studies came after soon. In the air pollution EKC was identified for SO₂, NO_x a dark matter (smoke), in water pollution for biological oxygen demand, chemical oxygen demand, nitrates and some heavy metals (such as arsenic, cadmium or lead). EKC evidence for particulate matter (PM) is mixed, EKC wasn t found for CO or CO₂ However, some authors consider evidence for EKC statistically weak. Standard explanation of EKC comes from [17]: &ldqou;As the development and industrailization progress, environmental damage increases due to greater use of natural resources, more emissions of pollutants, the operation of less effici-ent and relatively dirty technologies, the high priority given to increase in material output, and di-sregard for - or ignorance of - the environmental consequences of growth. However, as economic growth continues and life expectancies increase, claner water, improved air quality, and a generally cleaner habitat become more valuable…" EKC research has important policy implications: from some point environmental quality impro-ves with ecomic growth. Hence efforts to reduce economic growth to protect environment have in fact the opposite effect… [ABSTRACT FROM AUTHOR]
