The determination of the ‘optimal’ level of environmental pollution is based on the principle of maximization of the net benefits stemming from the reduction of environmental pollution.

For the determination of the optimal environmental protection, both abatement and damage cost functions have to be fully identified in order to estimate appropriately and realistically the corresponding benefits, aiming to achieve Pareto optimality.

Therefore in order to find the optimal pollution level, we will use these costs curves and we will determine the cost and the damage, of a country, or a provincial city or a municipality.

The intersection point will represent the optimal point. Assuming that the curves interact, an area called ‘benefit area’ can be estimated. We will prove that this interaction is not always acceptable, using three cases for both curves, as well as their combinations. That is: a. linear curves, b. quadratic curves and c. expotential curves.

In this way, the appropriate environmental policies and the corresponding environmental (qualitative or quantitative) tools will be proposed in cases of uncertainty of the environmental problem(s) at hand.
