Abstract:

As announced in our previous works, this paper is part of a larger research that deals with sustainable development and environment protection in extractive industry. As such, the next papers will deal with issues related to environmental pollution. In this respect, this paper is aiming to identify ways for pollution control through setting efficient environmental targets by analysing efficient levels of flow pollutants and stock pollutants, as we shall be able to appreciate the importance of the degree of mixing of a pollutant stock, while recognising and understanding the role of spatial differentiation for emissions targets. All of these will give us the opportunity of choosing pollution targets on grounds other than economic efficiency. As a result, in the end, to conclude on this part of analysis, a numerical model will be given to demonstrate that a marginal emission today has benefits only today, and so the present value of that marginal emission is identical to its current marginal benefit; in contrast, the damage arising from the marginal emission takes place today and in future periods.
