Summary

The summary tables provide an estimate of the levels of greenhouse gas emissions generated from activities of the State Services Commission (SSC). Some significant assumptions have been made in the preparation of these figures, particularly in relation to base building energy consumption, business travel and the amount of waste sent to landfill. Exclusions, assumptions and uncertainties around the data are described in sections 7 and 11 of this report.

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 being on the path to carbon neutrality by 2012.

2. Statement of intent

SSC 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 purpose of the SSC is to lead the State sector to world class performance through:

• overview and oversight of State Services delivery
• stewardship of State Services capability
• setting standards of behaviour
• providing guidance on systems and expectations
• appointing chief executives and managing chief executive performance in the Public Service
• advising Ministers
• administering policies
• enquiring and investigating
• service delivery.

Over the period from 1 July 2006 to 30 June 2007 the SSC comprised a total of 280 people across three sites. A total of 216 full time equivalent staff and 42 contractors were based from SSC's head office at 100 Molesworth Street, Wellington. A total of 18 staff, employed by Learning State, the public sector training organisation, were based in Featherston Street, Wellington. Four staff were based in a third location at Whitaker Place, Auckland.

4. Persons responsible (7.3.1 b)

The State Services Commissioner has overall responsibility for the emissions inventory.

This document and the associated spreadsheets have been prepared by the Performance Specialist with responsibility for leading the SSC's sustainability programme.

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.

Actual emissions

Emission source	Scope of Emission
Petrol for vehicles	Scope 1
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
Natural gas for base building heating in leased buildings which are multi-tenanted	Scope 3
Purchased electricity for base building power in leased buildings where the agency is not the sole tenant	Scope 3

No biomass is used in SSC 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)
Use of personal cars for business travel	Indirect (Scope 3)
Base building electricity for the Featherston Street site	Indirect (Scope 3)
Electricity purchased for lighting and utility/appliance power and base building electricity for the Auckland site	Indirect (Scope 2 and 3)

Justification

Staff commuting to work in personal cars. 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.

Use of personal cars for business travel. The SSC does at times reimburse staff for business travel undertaken in a privately owned vehicle. However, this is not currently captured in the financial management system in a way that is easily retrievable and the impact on SSC's total greenhouse gas emissions was not considered material.

Base building electricity for the Featherston Street site. Base building power for the Featherston site, which is multi-tenanted was not readily obtainable and would not have been material.

Electricity purchased for lighting and utility/appliance power and base building electricity for the Auckland site. This information was not readily obtainable and would have represented less than 1% of total electricity consumed by the SSC.

8. Base year selected (7.3.1 j)

This is SSC'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)

Petrol - regular	litres	0.0023154	1
International travel	Km	0.00011	2
Domestic travel	Km	0.00018	2
Taxi travel	Km	0.0002373	3

10. Emission reductions and removals (7.3.1 g)

SSC has achieved no significant emissions reductions for this reporting period as this is the first reporting period and established SSC's baseline year emissions.

SSC will have a management plan in place for managing and reducing emissions by early 2008 with the aim to be on a path towards carbon neutrality by 2012.

11. Uncertainties (7.3.1 o)

Emission Scope	Emission Source	Uncertainties
Scope 2	Electricity	Electricity consumption by kWh was available for the Molesworth Street office. Electricity consumption for the 18 staff based at Featherston Street was estimated by dividing the amount paid to the landlord by an estimated average charge per kWh.
Scope 3	Electricity and gas	Scope 3 electricity and gas consumption for the Molesworth Street office was calculated as a percentage share of the total base energy purchased for the site - which includes retail areas and the basement of the National Library building. The area rented by SSC represents 55% of the total site. It was assumed that SSC consumes 55% of the total amount of electricity and gas purchased for base building power. Energy purchased for lighting and appliances and base building power at SSC's Auckland site has not been included. Base building power for the Featherston Street site has also been excluded.
Scope 3	Waste to landfill	The SSC did not undertake a waste audit during the 2006/07 year. A waste recycling system was introduced late in the year which has substantially changed the amount and composition of waste sent to landfill. For this reason it was not appropriate to undertake a waste audit and apply it retrospectively. An estimate has been made based on an average bin weight multiplied by the number of bins sent for disposal at landfill for the Molesworth and Featherston Street sites.

12. Verification of the GHG Inventory (7.3.1 q)

This inventory has not been verified.

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