"This Act is about promoting the development and adoption of products to reduce energy use and greenhouse gas production (see the objects in Division 3 of this Part). This is achieved by applying greenhouse and energy minimum standards (GEMS) in association with the supply and commercial use of products that use energy, or affect the energy used by another product."
"Generally speaking, a product (a GEMS product) covered by a GEMS determination can only be supplied or offered for supply, or used for a commercial purpose, if:
(a) the model of the product is registered under this Act against the determination; and
(b) the product complies with the determination; and
(c) the supply, offer or use complies with the determination."
