1. Presented by: Michael Yard, IFES The 6 th GEO Conference, 2013 Creating a Methodology for Sustainability Assessment

2. Scope of Work Assess the costs of sustainability Financial Human resources Comparitive value

3. The Issues of Sustainability Can we maintain it? Can we store it? Can we replace it? Can we dispose of it when we’re done with it?
