The following items were identified as the key achievements and deliverables of this NGER review project:
Identification of methods to simplify the inventory development process
Dataset completeness was significantly improved with additional inventory items included
Site-developed venting methodologies were reviewed and refined
Energy and carbon management knowledge transfer and capacity development of client employees
Management was reassured about the reduction in business and non-compliance risks
The key objective of the project was to identify compliance gaps, address these gaps, support corporate office greenhouse reporting requirements and prepare the client for future compliance requirements.
Defining a program of works
Utilising our experience in assisting large oil and gas companies to respond to the requirements of the NGER Act, Energetics developed a structured approach to performing this internal NGER review.
In addition to reviewing against NGER legislative requirements, the project also involved comparing the client’s existing systems against its corporate office emissions reporting requirements, which prescribe the use of the American Petroleum Institute’s Compendium of Greenhouse Gas Emissions Methodologies (the API Compendium). The work also involved establishing a system to assess the uncertainty range of the Scope 1 emissions inventory, as part of NGER compliance requirements for 2010/2011.
This project work was performed at the client’s office which allowed for immediate access to, and understanding of, production accounting and fuel gas systems, financial systems and the activities and equipment at each of the facilities for which energy and emissions inventories were being compiled.
The initial audit component of the work meant that Energetics regularly held meetings with employees in IT, operations, finance, legal and environment departments. The legal team was particularly involved throughout the review of the process employed and documentation developed to support the finalisation of facility boundaries and operational control decisions.
Reporting and implementation
Once the information gathering component was complete, Energetics developed an NGER Compliance Actions Report with specific gaps, actions and recommendations. These gaps were ranked for prioritised action.
After the report had been presented to and approved by senior management, Energetics supported the client with implementing the actions recommended in its report. This included supporting with data gathering for the 2009/2010 inventory, development of incidental energy and emission methodologies and performing a final review of the calculated inventory.
Energetics provided assistance with upload into the Online System for Comprehensive Activity Reporting (OSCAR) database and the documentation of the inventory development process which was followed for the 2009/2010 period.
Currently, Energetics is supporting its client with the automation of its NGER inventory development in order to move from a spreadsheet system to an online database. With carbon pricing again on the horizon, with a proposed July 2012 commencement, the sooner large carbon emitters can move away from spreadsheets, typically vulnerable to human error, the better. This also ensures datasets are more readily available at shorter intervals, such as monthly rather than annually.
