This report evaluates how effectively Scotland's colleges have embraced and taken forward sustainability in the context of the Scottish Government's commitment to improve Scotland's natural and built environment and the sustainable use and enjoyment of it. "Greener Scotland" is one of the five strategic objectives that form part of the Government's National Performance Framework, which sets out the high level targets, outcomes and indicators applicable across the public sector in Scotland. Sustainable development is one of five strategic themes in the Scottish Funding Council's (SFC's) Corporate Plan 2009-122, which contribute to the achievement of the National Performance Outcomes. The plan highlights the Council's role in supporting research into renewable energy and the skills needed to support the renewable energy industry. It also confirms the Council's commitment to improving Scotland's natural and built environment and the sustainable use of resources through capital investment in buildings and through its policies and strategies for learning. The report aims to promote good practice in sustainable development and includes recommendations for improvement. Appended are: (1) Colleges involved in the fieldwork for this report; (2) Themes investigated in colleges; (3) Examples of sector-leading and innovative practice; (4) Glossary; and (5) Bibliography.
