The pageant, which was established in the Philippines, is one of the three largest beauty pageants in the world, along with Miss World and Miss Universe.
Based on a core principle of educating young people about environmental and humanitarian causes, the pageant includes traditional beauty contest aspects, such as swimsuit and ball gown competitions.
Contestants however are also judged on their involvement in and ability to communicate the importance of the global environment, working closely with the United Nations Environment Program.
Those who participate in the pageant are involved with humanitarian and environmental causes. The pageant winner is expected to be involved in international projects, which are also promoted during the pageant's broadcast. The delegates also take part in tree planting ceremonies, environmental and cultural immersion programs, sponsor visits and tours.
This year, the pageant will be held at the Marx Halle on December 5th. Austria's contestant is Sophie Totzauer. The show is expected to be particularly popular with the Filipino community in Vienna, as the incumbent Miss Earth 2014 is Jamie Herrell from the Philippines.
