Summary
No emissions have been excluded from this table other than those listed in item 7.
1. Introduction (7.3.1 p)
This emissions inventory report has been prepared and written in accordance with Part 7.3.1 of ISO 14064-1 and is designed to be used as in the process of becoming carbon neutral by 2012.
2. Statement of intent
The Department of Building and Housing is one of the 28 stage two core public service agencies that will be on the path to carbon neutrality by the year 2012. This programme will be broken down into three key stages which are set out below;
- Measure emissions
- Reduce emissions
- Offset unavoidable emissions1
3. Organisation description (7.3.1 a)
The Department of Building and Housing was established to bring together people and functions from across the government and takes a whole-of-sector approach to New Zealand’s built environment. The Department’s overall desired outcome is that ‘the people of New Zealand have access to quality homes and buildings that meet their needs, reflect our environment and contribute to a sustainable New Zealand’.
The Department is responsible for:
- administering building and housing sector legislation and its associated work programmes
- regulating the building sector and rental housing sector
- delivering effective information, advice and dispute resolution services
- providing policy advice to the government on the building and housing sectors
To this end the Department employs some 383 full time staff and a number of contractors and assessors at 22 locations throughout New Zealand.
4. Persons responsible (7.3.1 b)
- The Chief Executive has overall responsibility for the emissions inventory
- The Deputy Chief Executive, Corporate, will develop and approve the documents for the carbon reduction and neutrality programme
- The following people will be involved in the preparation of these documents:
- Chief Advisor, Finance Planning and Administration
- Administration Manager
- Finance Manager
5. Organisational boundaries included for this report period (7.3.1 d)
The Agency uses the financial control based approach to defining organisational boundaries. Due to the legally prescribed nature of the core public service, the application of either the control or equity approach is likely to have the same effect, as government agencies do not have subsidiaries, associate companies in the same manner that private sector companies have group structures, or complex lease arrangements.
The organisational boundaries of an agency are defined by statute and for the purposes of the GHG inventory include core agency activities only.
6. Emissions sources inclusions (7.3.1 e)
Emission sources were identified with reference to the methodology described in the GHG Protocol and the ISO 14064-1 (2006) standard. Identification of emissions sources was achieved using the specific guidance on Scope 3 factors included in the Cabinet Paper POL (07) 131: Towards a Sustainable New Zealand: Carbon Neutral Public Service. Further guidance was obtained from the Ministry for the Environment.
These emissions have then been classified into three categories. The definition of each has been adapted from the GHG Protocol; the three types of emissions are;
- Direct emissions (Scope 1): emissions from sources that are owned or controlled by the agency.
- Indirect emissions (Scope 2): emissions from the generation of purchased electricity consumed by the agency.
- Indirect emissions (Scope 3): emissions that occur as a consequence of the activities of the agency, but occur from sources not owned or controlled by the agency. Inclusions of these are determined on case by case basis, and relate to the agency’s aims of the programme.
| Emission source |
Scope of Emission |
| Petrol for vehicles |
Scope 1 |
| All purchased electricity in owned buildings and leased buildings where the agency is the sole tenant |
Scope 2 |
| Purchased electricity for lighting and utility/appliance power in leased space where the agency is not the sole tenant |
Scope 2 |
| Transmission and distribution line losses for all purchased electricity |
Scope 3 |
| Domestic air travel |
Scope 3 |
| International air travel |
Scope 3 |
| Taxi travel |
Scope 3 |
| Business travel in rental cars |
Scope 3 |
| Waste to landfill |
Scope 3 |
No biomass is used in the Department of Building and Housing’s operations and therefore no emissions from the combustion of biomass are included. (7.3.1 f)
7. Emission sources exclusions (7.3.1 h)
| Emission Source |
Emission Level Scope |
| Staff commuting to work in personal cars |
Indirect (Scope 3) |
| |
|
Justification; This is considered to fall under the personal carbon foot print of the employee as the agency has little control over where people choose to live; therefore this is outside the Scope. Work will be undertaken to produce travel plans to help reduce this effect under a further scheme.
For further information see the document ‘Carbon Neutral Public Service Emission Inventory Preparation Guidance’
8. Base year selected (7.3.1 j)
This is The Department of Building and Housing’s first report. The chosen base year calculated for this report is the year from 1 July 2006 to 30 June 2007.
9. Data collection quantification of methodologies (7.3.1 l and n)
The table below details the sources of the relevant data and the emission factors which have been used. All the factors have been approved by the Ministry for the Environment. The amount of C02e has been calculated by multiplying the activity data sourced by the agency by the relevant emission factor. As this is the first year that the agency has produced these figures there have not been any changes in methodology to report. (7.3.1 k)

10. Emission reductions and removals (7.3.1 g)
The Department of Building and Housing has achieved no significant emissions reductions for this reporting period as this is the first reporting period and establishes baseline year emissions.
The Department of Building and Housing will have a management plan in place for managing and reducing emissions by early 2008 with the aim to be carbon neutral by 2012.
11. Uncertainties (7.3.1 o)
There needs to be a description of the impact of uncertainties on the accuracy of the GHG emissions and removals data.
| Emission Scope |
Emission Source |
Uncertainties |
| Scope 3 |
Domestic and International flights |
It is assumed that records supplied by Atlantic Pacific Travel are complete and accurate |
| Scope 3 |
Waste to landfill |
An extrapolation of the data from the waste audited sites has been made to the non audited sites. |
| Scope 1 |
Petrol usage |
As litres were not recorded in this year an average per litre cost was assumed and the fuel account divided by this. |
| Scope 3 |
Electricity |
In some of our premises electricity is included in the rental charge and not identifiable |
12. Verification of the GHG Inventory
This inventory has not been verified.

1 The term “unavoidable emissions” should be understood to include a cost-benefit analysis of the reduction measures.
