Millions of events of all shapes and sizes are held in the world every year, from the smallest fairs to the world's largest festivals, concerts in stadiums, conferences, exhibitions and sporting events. Such public gatherings consume resources, pollute the environment and generate large amounts of waste. On the other hand, they cause a lot of smiles and happiness, connect communities, celebrate certain occasions and provide a popular form of entertainment. A typology based on the types of events and the main types under consideration is presented, and this classification is mainly based on their form. It has been argued that events cannot be easily classified based on experiences because there are multiple experiences within any form of event. An overview of all the main types of events, from cultural celebrations to private functions, summarizes their multiple meanings and the way they are designed and programmed. People come to events with specific needs and expectations to experience something different and participate usefully in the program of events with other people through behavior, expression of emotions, and cognitive processes. The more a person is involved or engaged in an event, the more benefits they will derive from the experience and the more they will remember it. Individuals, groups, societies, and businesses all assign meaning to events. Different event participants will have different motives, experiences and meanings, so event organizers must adapt their approach to different stakeholders. All events have something in common, and that is that they can strive to provide general benefits such as entertainment, social interaction, learning, and communication. Whenever there is a huge gathering of people, it is understood that they will have an impact on the surrounding air, land and water, with impact effects on the wider environment. At any major event, resources will be used, there will be vapors, waste and sewage. At the same time, events have a duty to reduce negative impacts on the environment and increase the benefits to the community and the planet. Event organizers play a key role in making events environmentally friendly, from supply chain management to activities and content available to participants. Events contribute to host destinations through economic sustainability by raising the profile of the area through employment, trade and business development, which can increase tourism potential and raise awareness of the future. The events certainly have a great positive economic impact for the host destinations. They can also help create economic and social solidarity, increase self-confidence and pride between the local community and government. Events have direct and indirect links to the environment. Most events have certain common features and environmental impacts. First, they contribute to the depletion of natural resources, air, water and soil pollution. Secondly, they endanger the habitats of plants and animals and destroy them. Sustainable event organizers should consider controlled use of resources, limiting excessive consumption and reducing waste, preserving diversity, and integrating event management into long-term development concepts. Events can be considered social phenomena that involve social interaction between event participants and the host community, which causes social change. The choice of events is influenced by social status and norms and values of society. Events attach us to contact between two groups of people, event participants and the host community, where both groups experience the changes created by the interaction itself. Over the last decade, environmental protection and the many challenges it poses to society have become increasingly debated and in many ways increasingly complex. Environmental protection has moved from social and political consciousness to one of the main concerns of the community, of international importance. Formerly known as “global warming” or the “greenhouse effect” has proven to be such a phenomenon that requires urgent human attention, not only because of the amount of change to the natural environment, but also because of the rapid rate of that change.
