The first is WEEE, the European Community directive on waste electrical and electronic equipment and the second is the RoHS Directive.
WEEE sets collection, recycling and recovery targets for all types of electrical goods, including computer equipment. The RoHS directive restricts the use of certain substances (lead, mercury, cadmium, hexavalent chromium and two flame retardants - PBB and PBDE) in electrical and electronic products sold in the European Union after July 1, 2006.
Computer equipment purchasers should be aware that there are companies which, for manufacturing reasons, were granted RoHS exempt status rather than RoHS compliant status, and you should be careful you choose solutions with the 'compliant' label.
Considering and implementing 'green' issues is increasingly important in IT and IT security is no exception. Choosing suppliers who implement 'green' policies, considering solutions such as UTMs, and selecting products which conform to WEEE and the RoHS directive are all ways in which IT security can be 'greener.'
