The group incudes the NZ Government, national grid operator Transpower, electricity generators and other large electricity users.

The agreement aims to adopt best practices to minimise sulphur hexafluoride emissions; set and meet emissions targets (in the case of major users), and report on sulphur hexafluoride use in accordance with internationally recognised guidelines.

Playing its part, the Government said it would exempt users of sulphur hexafluoride from costs arising from its use under climate change policies.

“I welcome the responsible stance being taken by users towards minimising sulphur hexafluoride emissions," says Energy Minister and Convenor of the Ministerial Group on Climate Change, Pete Hodgson.

"Transpower is committed to minimising emissions of this greenhouse gas, and the signing of the agreement provides a useful framework within which this goal can be achieved," says Transpower’s Chief Executive Dr Ralph Craven.

Transpower worked with the Government on behalf on sulphur hexafluoride users in the development of the agreement.

The other electricity users who are being invited to sign the agreement include Vector, Meridian Energy, Mighty River Power, Genesis Power, Contact Energy and Comalco.
