The international community decided that the global temperature cannot rise more than 2°C comparing with the level before the period of industrialisation that the climate changes do not reach a dangerous level. Therefore, EU endeavours to induce the member countries to reduce the emissions. In turn, each of the countries in various areas of functioning of their economies and households seeks reduction of harmful emissions having influence on increase of the temperature in the local scale. In this article there is taken an attempt to present the problem based on the example of the Czech-Polish border and especially on the terrain of Cieszyn city. (original abstract)

This article is a continuation of research on the possibilities of the use of fuzzy logic systems and higher-order fuzzy logic to control the air filters to reduce emissions of nitrogen oxides. The control process is non-linear, therefore, it is reasonable to use the fuzzy controllers. Described in this paper an interval-valued fuzzy controller (in sense Mamdani) uses interval-valued fuzzy sets compartments. They describe the use of terms of linguistic levels of nitrogen oxides at the input of the system and the degree of opening of the metering valve in the filter ammonia, based on data obtained from an expert. Using IF-THEN rules interval-valued fuzzy controller calculates the value of the output of the filter set on the basis of the analysis of data-input. The results obtained are very highly consistent with the data provided by the expert and better compared to those obtained with the traditional fuzzy controller, the use of which is presented in the articles.
