Sustainable event management (also known as event greening) is the process used to produce an event with particular concern for environmental, economic and social issues. Sustainability in event management incorporates socially and environmentally responsible decision making into the planning, organization and implementation of, and participation in, an event. It involves including sustainable development principles and practices in all levels of event organization, and aims to ensure that an event is hosted responsibly. It represents the total package of interventions at an event, and needs to be done in an integrated manner. Event greening should start at the inception of the project, and should involve all the key role players, such as clients, organizers, venues, sub-contractors and suppliers.
