This is a one hour workshop presented at the ACTS2011 conference in Adelaide. A variety of models and frameworks are used generate understanding of the barriers and drivers to build momentum for system (organisational) transformation towards sustainability. The workshop begins by encouraging participants to envision a sustainable campus. Current actions for sustainability across the key functional areas of research, teaching and learning, campus operations and community outreach are acknowledged and opportunities to build further momentum are identified. Finally, strategies are offered to synergise across these initiatives to achieve organisational transformation to sustainability. A case study of Harvard University is also provided to demonstrate how such a transformation can be achieved.
