The Equipment Energy Efficiency (E3) program is a cross jurisdictional program through which the Australian Government, states and territories and the New Zealand Government collaborate to deliver a single, integrated program on energy efficiency standards and energy labelling for equipment and appliances.

​

It is one of a number of programs implemented by the Council of Australian Governments (COAG) Energy Council.  An Inter-Governmental Agreement provides the framework for national cooperation on the E3 Program. A similar arrangement has also been developed to ensure alignment with New Zealand.

​

On 1 October 2012, the Greenhouse and Energy Minimum Standards (GEMS) Act 2012 came into effect, creating a national framework for product energy efficiency in Australia.  The GEMS Act is the underpinning legislation for the program.

​

The GEMS Regulator, based in the Commonwealth Department of the Environment and Energy, replaced the previous state regulators and is the sole party responsible for administering the legislation in Australia.

​

In New Zealand, the Energy Efficiency (Energy Using Products) Regulations 2002 have a similar role and are administered by the Energy Efficiency and Conservation Authority (EECA).
