In February 2014, the New South Wales government invited David Crossley to speak at a Sydney forum concerning the forthcoming review of the NSW energy efficiency obligation (EEO) scheme. An EEO is a regulatory mechanism which requires the obligated parties to meet energy saving targets by delivering or procuring eligible energy savings by means of approved end-use energy efficiency measures. All EEO schemes feature three key elements. First, a quantitative target for energy efficiency improvement. Second, obligated parties that must meet the target. Finally, a system that a) defines the eligible energy efficiency activities that can be implemented to meet the target, b) measures, verifies and reports the energy savings achieved through these activities, and c) confirms that the activities actually took place. Dr Crossley’s presentation identifies best practices in designing and implementing EEO schemes based on a review of 19 EEO schemes in various jurisdictions around the world.
