Standardization in tourism refers to the establishment of norms, guidelines and regulations that regulate the quality of service and business in the tourism sector. This practice has a key role in ensuring a high level of service quality, protecting the interests of consumers and promoting the sustainable development of tourism. One of the main goals of standardization in tourism is to achieve consistent quality of services in different tourist destinations and sectors. This is achieved by establishing norms for various aspects of tourism, such as accommodation, food, transport services, tourist attractions and other relevant areas. They define the minimum requirements that must be met in order to ensure a high level of service quality, guest safety and satisfaction. They also provide guidance on transparency, fair trade, consumer rights and environmental protection. Taking into account the specific needs and expectations of guests, the norms facilitate making informed decisions about the selection of tourist products and services. The introduction of norms in tourism also promotes sustainable development, often including guidelines for environmentally friendly practices, energy efficiency, protection of natural resources and preservation of cultural heritage. Sustainable tourism is becoming increasingly important to ensure that tourism contributes to local development without negative impacts on the environment and community.
