This Regulatory Impact Statement (Report 2007/07) was prepared for the Equipment Energy Efficiency Committee, which reports to the Ministerial Council on Energy. The MCE determines end-use equipment energy efficiency regulatory proposals involving all Australian Governments (Commonwealth, State and Territory) and the New Zealand Government. This is a revised regulatory impact statement (RIS) proposing the introduction of common minimum energy performance standards (MEPS) in Australia and New Zealand for an energy using product know as an external power supply (EPS). An initial Consultation RIS was released in March 2007 . Stakeholder submissions called for changes to that proposal and this revision, taking account of those stakeholder submissions, represents the latest proposed recommendations of energy efficiency regulators to the Ministerial Council on Energy.
