You may like save at any point and continue later. We do not ask for any identifying details.

If you have saved your calculations you can load your figures by entering your unique code and your passprase.

You can download the full calcuations into an Excel spreadsheet so you can use it as a starting point for your reporting.
This calculator follows the structure recommended by the Ministry for Enviornment. It should be used in conjunction with NZBCSD's How-to Guide and the Ministry for Enviornment's Guidance for Voluntary, Corporate Greenhouse Gas Reporting (2006,2007, 2008).

Disclaimer
This calculator is to be used for Voluntary reporting only. It is provided "as is" without any warranty of any kind. Users are expected to check the calculations and seek professional advice if relying on the results for any purpose whatsoever.

Instructions
Fill in the "Amount" field and select the "Unit" for any of the "Emission sources" listed below that are relevant to your business. Select the "Supplier" from the dropdown list where available, which enables us to calculate offsetting provided by some suppliers. Click the "note" link to view any notes (in a popup window).

Select your reporting period here. The calculator will calculate CO2 emissions for each quarter based on MFE emissions factors for the relevant quarter and add up the totals over the period.

Multiple years
If you have figures for calendar years 2006, 2007 and 2008, you should run the calculations once for each year. First calculate 2006 Q1 to 2006 Q4, then calculate 2007 Q1 to 2007 Q4, and then calculate 2008 Q1 to 2008 Q4. You can enter, save and export each calculation sheet separately. You can then use the exported figures to do your own comparison and analysis.

Scope 1 (Direct Emissions):

Direct GHG emissions occurring from sources that are owned or controlled by the company (ie, sources within the organisational boundary). For example, emissions from combustion of fuel in owned or controlled vehicles. The GHG Protocol and ISO 14064-1 require Scope 1 emissions to be reported.

1. Stationary combustion of fuels
Scope 1 emissions occur from the combustion of fuels from sources owned or controlled by the reporting organisation. These are emission factors for common fuels used for stationary combustion.

In line with the reporting requirements of ISO 14064-1 and The GHG Protocol, emission factors are provided to allow calculation of CO2, CH4 and N2O separately.

2. Transport fuels (where fuel use data is available)
Scope 1 emissions from transport occur from vehicles which are owned or controlled by the reporting organisation. The most accurate way to quantify the emissions associated with transport is by using information on the quantity of fuel used.
The emission factors are sourced from the Energy Greenhouse Gas Emissions (2009) publication.

3. Transport where no fuel data is available (based on distance travelled)
If your records only provide information on kilometres travelled, and you do not have information on fuel use, the emission factors can be used to calculate emissions from transport. Note, however, that factors such as individual vehicle fuel efficiency and driving efficiency mean that kilometre-based estimates of CO2-e emissions are less accurate than calculating emissions based on fuel-use data. The emission factors should therefore only be used if information on fuel use is not available.

Car - medium (1600<2500> km0
Car - large (>=2500 cc) km0

4. Refrigerants
Greenhouse gas emissions from hydrofluorocarbons (HFCs) are associated with unintentional leaks and spills from refrigeration units, air conditioners and heat pumps. While quantities of HFCs reported in a business emissions inventory may be small, HFCs have very high global warming potentials (commonly 1300 to 3300 times more potent than CO2) and emissions from this source may therefore be material. In addition, emissions associated with this sector are growing significantly as they replace hydrochlorofluorocarbons (HCFCs).

Scope 2 (Indirect Emissions):

These refer to emissions consumed by the organisation. Electricity emissions are given their own special reporting category (scope 2), because for most organizations, electricity emissions represent a large proportion of their carbon footprint. Scope 2 is now generally taken to include the emissions from electricity, heat or steam. Purchased electricity is defined as electricity that is purchased or otherwise brought into the organizational boundary of the company. Scope 2 emissions physically occur at the facility where the energy is generated.

1. Purchased electricity
An emission factor for the consumption of purchased electricity (by end users) is calculated on a calendar year basis, and accounts for the emissions from fuel combustion at thermal power stations. It also includes a relatively small proportion of fugitive emissions from geothermal generation.

The emission factor for the consumption of purchased electricity and the emission factor for transmission and distribution line losses have been aligned with the definitions used in the GHG Protocol.

The electricity emission factor covers purchased electricity which has been bought from an electricity supplier who sources its electricity from the national grid.

Scope 3 (Indirect Emissions):

These refer again to emissions that occur due the consumption of goods or services by the reporting organisation. However, Scope 3 is an optional reporting category that allows for the treatment of all other indirect emissions. Scope 3 emissions therefore are a consequence of the activities of the company, but occur from sources not owned or controlled by the company. Some examples of Scope 3 activities which are commonly measured and reported by New Zealand organizations are air travel, waste, taxi usage, rental car hire and reimbursement of employee travel in employees’ own cars.

Including Scope 3 in your calculations is also an opportunity to clearly communicate to your stakeholders, including customers and suppliers, that you are serious about your business’ commitment. This guide recommends incorporating your Scope 3 emissions where appropriate.

1. Transmission and distribution line losses for purchased electricity
The transmission and distribution line losses emission factor accounts for emissions from the generation of the electricity lost in the transmission and distribution network due to inefficiencies in the grid. Under The GHG Protocol reporting framework, emissions from the generation of electricity that is consumed in a transmission and distribution system should be reported as a Scope 3 emission by end users.

The emission factor for transmission and distribution line losses is the difference between the generation and consumption emission factors reported by the Ministry of Economic Development on their website.

2. Transmission and distribution losses for distributed natural gas
The transmission and distribution losses emission factor for distributed natural gas accounts for fugitive emissions, from the transmission and distribution system, which occur during the delivery of the gas to the end user.

This emission factor is derived based on information from the Energy Greenhouse Gas Emissions (2009) and New Zealand Energy Data File 2009 publications.

3. Taxis and rental cars
Business travel in taxis and rental cars are likely to be a common source of Scope 3 emissions for most businesses. As with Scope 1 emissions from transport, the most accurate way to calculate emissions is based on fuel consumption data. However, this information may not be easily available, particularly for business travel in taxis. The emission factors for rental car and taxi travel are based on kilometres travelled, and the emission factor for taxi travel are based on dollars spent.

4. Air travel
The emission factors provided are intended for use by organisations wishing to report their air travel emissions, based on the distance travelled per passenger. The emission factors provided follow those published by the UK Department for Environment Food and Rural Affairs (DEFRA) in their 2009 Guidelines to DEFRA / DECC's GHG Conversion Factors for Company Reporting. These are deemed to be the most suitable emission factors currently available. The DEFRA publication discusses the emission factor methodology in more detail, including changes in methodology over time.

5. Waste to landfill
The emission factors and methodologies provided below will help organisations in estimating their emissions from waste disposed of at a landfill. Emission factors are based on figures from New Zealand’s Greenhouse Gas Inventory 1990–2007 and methodologies are derived from IPCC good practice guidance.

Methodologies to determine emissions from wastewater treatment and solid waste incineration are not covered by this guide, as emissions are assumed to be negligible at the individual organisation level (with some exceptions for large industrial wastewater producers).

The anaerobic decomposition of organic waste in landfills generates methane (CH4). Inventories should be adjusted to account for the landfill gas that is collected and destroyed. The methodologies outlined below provide for such adjustment depending on whether an organisation’s waste is sent to a landfill with (or without) a landfill gas collection system.
