Creating a Methodology for Sustainability Assessment Presented by: Michael Yard, IFES The 6 th GEO Conference, 2013
Scope of Work • Assess the costs of sustainability • Financial • Human resources • Comparitive value
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?
Can We Maintain It? Computers - startup and test # computers test frequency (weeks) # to be tested per week

Can we dispose of it ? • Data considerations • Cost recovery • Who can receive it? • Environmental considerations • Risks to reputation of EMB
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?
