New Zealand was a very early signatory to the Kyoto Protocol, reflecting a long history of leading-edge environmental policy initiatives, and exemplifying the country's “clean, green” image. A spectrum of strategies, guidelines and policies has been implemented at Central Government level in response to New Zealand's commitment to meet its Kyoto Protocol targets. Local Government operations will be directly impacted by these new energy sustainability drivers. In addition, solid waste and wastewater utilities will come into the new carbon trading scheme in 2013, as the last major group of sector industries to be affected.

Wastewater operations are estimated to account for up to 20% of Local Government energy use This paper is intended to provide an awareness of the drivers that impact the path to energy sustainability in wastewater treatment operations. Technical solutions to improve energy efficiency and generate renewable energy relevant to the New Zealand wastewater sector are presented.
