The People & Planet Green League is the only comprehensive and independent ranking of United Kingdom universities by environmental and ethical performance and practice.
It initially scored UK universities on four key institutional factors needed to drive forward significant and sustained improvement in environmental performance, as highlighted by the Going Green report.
The aim of this process is to respond to new environmental concerns, push transition further and incorporate feedback and criticism from previous years to improve the accuracy and transparency of the Green League.
The ranking also did not incorporate the amount of Environmental Research and Teaching, which while not directly contributing to any reduction in the university's carbon footprint, does serve to educate the next generation, and may reveal a new way to increase sustainability.
The University of Greenwich is another institution which believed that the criteria for marking was too limited, and following several criticms[6] Green League acknowledged that it needed to expand its indicators, which it has done in the following years.
