The topic of the final thesis is the principle of proportionality and opportunity related to protection against environmental pollution from harmful noise emissions. Today, the issue of the environment represents one of the most represented topics in the wider public. All people have the right to a clean, healthy and sustainable environment. As human rights and the environment are interdependent, a clean, healthy and sustainable environment is necessary for the full enjoyment of a wide range of human rights, such as, among others, the rights to life, health, food, water and sanitation and development. The constitutional arrangement of the environment and its protection is one of the most urgent tasks of human civilization today, as well as ensuring a harmonious environment in the interaction of nature and society. Recognizing noise as a potential risk can be just as challenging as other health risks, as they are often dealt with reactively. Immission is the term for all forms of environmentally harmful emissions from industrial plants, and includes in one word air pollutants, noise, vibrations, ionized and non-ionized radiation of any wavelength, unpleasant or harmful odors, etc. The right to protection against emissions belongs to the property owner and all persons who own real estate on the basis of rights derived from them. The basic authority of the owner who is being disturbed by someone is to demand the cessation of the disturbance, which means that a negative action (actionegatoria) is the basic legal instrument of noise protection.
