Meridian Energy Group Greenhouse Gas (GHG) Inventory Report
Greenhouse Gas Inventory
The following information has been summarised from the full
Meridian Energy Group Greenhouse Gas Inventory for the 1 July 2007
to 30 June 2008 period.
Statement of Greenhouse Gas (GHG) Inventory policies
Meridian seeks to adhere to best practice in its greenhouse gas emission
reporting. For that reason the following GHG accounting methodologies
have been applied to the Meridian Energy GHG Group Inventory:
• The Greenhouse Gas Protocol: A Corporate Accounting and Reporting
Standard (revised edition) developed by the World Resources Institute
and the World Business Council for Sustainable Development (2004).
This is referred to as GHGP.
• ISO14064-1:2006 Specification with Guidance at the Organization Level
for Quantification and Reporting of Greenhouse Gas Emissions and
Removals. This is referred to as ISO14064-1.
Basis of preparing group GHG inventories
Organisational boundary and consolidation approach
The organisational boundary sets the parameters for GHG reporting
in the Meridian Group GHG Inventory. The boundary is determined by
the operations owned or controlled by Meridian depending on the
consolidation approach taken. The consolidation approach is applied
to subsidiaries, associate companies and joint ventures in the Meridian
Energy group to determine how emission sources are reported in the
Meridian Group GHG Inventory.
Meridian applies the equity share consolidation approach. This means
that Meridian will account for greenhouse gas emissions from all
activities within its corporate boundary and a percentage of the
emissions from entities in which it has an equity interest according
to its share of equity in the entity.

The emissions for the group have been identified for separate facilities
(as defined by ISO14064-1) as outlined below:

Changes to reporting
The methodology used to prepare the GHG inventories is unchanged.
Base Year
This is the first year formal inventories have been prepared for all
facilities and the Group as a whole. There has been some reclassification
in the 07/08 year to separately show subsidiaries/facilities which were
previous reported under the Meridian Energy Facility.
The base year selected is 1 July 2007 to 30 June 2008.
As this is a revised base year a comparison with the footprint for the
Meridian Energy facility published in last year’s Annual Report is not
being made. The total CO 2 emissions reported for the Meridian Energy
facility for the 2006/07 year were 5,416 tonnes.
For consistency and treatment of all facilities in the Group, the 2007/08
base year will also apply to the Meridian Energy Facility in place of the
2005/06 base year applied for the first carboNZero cert TM certification of
that facility.
