Also look into the work done by PRME (Principles for Responsible Management Education). It may not be in line with your particular scope, but would provide some guidance.
I have two papers coming up on the topic, here are some excerpts that might be useful.
"In 2002, in a historical move, United Nations declared the decade 2005-2014 as the Decade of Education for Sustainable Development (DESD) to promote education for sustainable development. HEIs, in comparison with the corporate world, have been slow to integrate sustainability into their systems."
"The upsurge of sustainability declarations and initiatives started a snowball effect among HEIs by incentivizing them to recognize their role in sustainable development, nonetheless, despite the lip service, little progress been made with the integration of sustainability in the educational agenda." Here are sample some sustainability declarations and initiatives:
"Tbilisi Declaration
1977 (Tbilisi, Georgia)
It emphasized on the importance of environmental teaching, research, and training, as well as technical and vocational education. It also recognized the vital interdisciplinary nature of environmental education."
"Talloires Declaration
1990 (Talloires, France)
A ten-point action plan for incorporating sustainability and environmental literacy in teaching, research, operations and outreach at colleges and universities and a commitment to environmental sustainability in higher education, signed by over 421 college and university presidents and chancellors in 52 countries."
