The ranking  agency UI Green Metric  World  University Rankings,  established in 2010 by the University of Indonesia, ranks universities around the world in  six categories:

      - convenient  university  in   frastructure;

      - the use of energy-efficient  and water-conserving technologies on  the university campus;

      - recycling  programs for waste discarded  by the university

      - water conservation;

      - convenient transport routes on  the university campus, reducing emissions of carbon dioxide and harmful  particles;

      - environmental education inuniversity educational programs.

      The purpose of this ranking is  to evaluate the current status and policies related to green campus and  sustainability  at universities around the world and reflects the efforts made  by an institution to implement green and sustainable policies and programs.

      Overall, the ranking uses the  concept of environmental sustainability,  which includes three elements such as  environmental, economic and social.

      The environmental aspect  refers to the use of natural resources, environmental management and pollution  prevention, while the economic  aspect refers to  cost savings  and profit  making.  The social aspect includes  education, community and social inclusion.

      The university's  work is  assessed using  six indicators: environment  and  infrastructure, energy and  climate changes, waste, water, transport, education  and  research.  For participation in the ranking,  universities  must provide not only quantitative  data about their university,   but also confirm   this information by approved regulatory documents, scans of  orders, news from the  media, photographs, etc.
