Why bother?

Reputation Cost savings Social responsibility

Global (resources, carbon) Local environment (heat, footprint,

H&S) Compliance

New Vs Old

New build – an opportunity for change

Legacy kit – counting the cost Existing build & infrastructure

Before green was popular

Print consumables LCD monitors No inkjets Refurbished PCs Re-cycled equipment (PCs & CDs) Auto shutdown student PCs

What came next?

Classroom & Office PCs – tower, small form or laptop? Repro – wastebin, duplex, mono, print

quotas, MFDs. AV – auto shutdown projectors, plasma E-forms – e-registers, progressions

other docs. Sustainability as part of the

procurement policy.
