UI GreenMetric World University Rankings

Universitas Indonesia has been asking universities to take part in a ranking based on "university sustainability."  According to UI:

"The world faces unprecedented civilizational challenges such as population trends, global warming, and overexploitation of natural resources, oil-dependent energy, water and food shortages and sustainability. We realize that higher education has a crucial role to play in addressing these challenges. UI Green Metric raises awareness as it helps assess and compare efforts at education for sustainable development, sustainability research, campus greening, and social outreach."

The ranking has six criteria: Setting and Infrastructure, Energy and Climate Change, Waste, Water, Transportation and Education.

The ranking is based entirely on data submitted by universities and that in itself drastically limits its validity. Also, should the promotion of sustainability, however worthy a cause, be a major concern of universities. Is there nobody else taking an interest in such things?
