A national workshop between the Accounting Department/Cihan University and the International Trade Department/College of Law and Administration/Halabja University held entitled “Environmental pollution, its determinants and methods to treat it”. As part of their efforts to enhance the economic well-being of their citizens, the countries of the world faced deterioration in the quality of the environment as a result of the resulting pollution, especially in the early stages of its development. The relationship between economic growth and environmental degradation has been extensively studied, since 1991. This workshop will focus on determining the causes of pollution, with a focus on the emission of carbon dioxide, as it constitutes the largest part of greenhouse gases.
