Guidance for voluntary, corporate greenhouse gas reporting

Data and Methods for the
2007 Calendar Year

This is the second version of an annual publication.

Each year the Ministry for the Environment will update this guide with emission factors for the previous calendar year. It does not replace previous editions of this publication.

Changes to data and methodology for the 2007 calendar year

Scope 1

Stationary combustion – emission factors for stationary combustion have been updated based on new figures for the 2007 calendar year.

Transport fuels – emission factors for transport fuels have been updated based on new figures for the 2007 calendar year.

Refrigerants –refrigerant emission factors and methodologies to account for, and screen the materiality of, refrigerants are now included in the guidance publication.

Scope 2

Purchased electricity – emission factors for purchased gas and electricity have been updated based on new figures for the 2007 calendar year.

Scope 3

Transmission and distribution losses – emission factors for transmission and distribution losses from purchased electricity and natural gas have been updated based on new figures for the 2007 calendar year.

Taxis/rental cars – emission factors for travel in taxis/rental cars have been updated based on new figures for the 2007 calendar year.

Air travel – emission factors for air travel have been updated due to changes to the methodology and data used for calculating emissions from air travel.

Waste – emission factors for waste to landfill with methane capture have been updated based on new projected methane capture data for the 2007 calendar year.
