This paper will present all the ways nautical tourism has an impact on the environment and it will explore the standards of environmental protection in nautical tourism on the examples of the world countries. Nautical tourism is one of the most important drivers of economic development in the world, but it also brings many changes that occur in the marine environment under the influence of increased demand and increased circulation of yachts and boats. With the development of nautical tourism, there is an increase in the number of vessels, berths and new nautical ports, and the possibility of pollution of the sea and the coast significantly increases. Environmental problems cannot be maintained only within national borders and frameworks because environmental threats have a much larger impact. Therefore, regulations for pollution prevention and environmental protection are established at the international level and everyone must adhere to them. The paper presents legal regulations at the international level and numerous international, regional and national standards that individual areas and countries apply for the purpose of nature conservation and protection.
