The objective of the article is to present legal solutions adopted in the National Air Pollution Control Programme (further referred to as the NAPCP) in Poland. This is preceded by an analysis of this document in the context of other legal instruments for environmental protection, and an evaluation of its effectiveness.

The paper uses the formal and dogmatic method, based on the examination of the texts of legal acts and views expressed by legal academics and commentators as well as judicial decisions. The aim of its use was mainly to make a review of the provisions concerning the examined issue and their interpretation.
