Frequently Asked Questions

I have a specific company in mind. What is the quickest way to find its data?

You can search for the company on the Companies page or use the search feature on the top navigation. When you have located the company of interest, click the company name to access its Company Profile, where you can view all data available for that company on the NZDPU.

Each company on the NZDPU has its own Company Profile, which contains all data available (current and historical) on the NZDPU. You can access a Company Profile by locating the company of interest on the Companies page, Data Explorer, or by using the search feature on the top navigation.

The NZDPU Data Explorer allows you to build data tables for multiple companies and reporting years at once. The Data Explorer has two modes:

  • The Help Me Get Started mode offers a quick and curated search capability to get you started.
  • The Advanced Search mode offers additional filters and column selection capabilities. You can switch from the Help Me Get Started mode to the Advanced Search mode at any time without losing your query input or results.

You can access the NZDPU Data Guide in multiple places and formats.

  1. While viewing any Company Profile or using the Data Explorer, you can click the “NZDPU Data Guide” on the right side of the page. You can view definitions of each data field by:
    1. Browsing lists of data fields by section
    2. Searching for data fields by keywords
  2. You can download the NZDPU Data Guide in its entirety as a PDF, from the Documentation page.

The NZDPU requires users to be logged into their NZDPU account to download data. NZDPU accounts are free for everyone. You can create a free account in minutes.

By creating an NZDPU account, you can enjoy the benefits of downloading data and generating access tokens to use NZDPU’s APIs. NZDPU accounts are free.

Yes. The APIs have the same functionalities and data as those which are available on the Companies, Data Explorer, and Company Profile web interfaces.

T2COe, which stands for tonnes of carbon dioxide equivalent, is a measurement of the total greenhouse gasses emitted, expressed in terms of the equivalent measurement of carbon dioxide when the respective Global Warming Potential (GWP) values and time horizons of each greenhouse gas included in an inventory has been accounted for. In contrast, t2CO (or tonnes of carbon dioxide) solely reflects carbon dioxide emissions and does not account for any other greenhouse gasses. Note that 2CO emissions can also be presented in units of 2COe, where 1 t2CO = 1 t2COe.

For a given emissions field in a given year, the NZDPU displays the emissions figure in either—but not both—t2COe or tonnes of t2CO.

For the Proof of Concept, CDP has supplied an initial set of direct (Scope 1) and indirect (Scope 2 and Scope 3) GHG emissions, and GHG emissions reduction targets data from 382 companies that disclose publicly through CDP. As such, for each data point, the source column is populated based on the relevant CDP Climate Change questionnaire for that year. To learn more, click here.

The NZDPU aims to serve as a central repository of GHG emissions and targets data available through various third-party disclosure channels, which are the originating sources for the data.

Where there is no data on the NZDPU for a particular company or data field, it could be due to one of several reasons:

  1. The field existed in the originating data source for the given reporting year, but the reporting company did not provide any data, or input a “-” value, for this field to the source.
  2. The field was not in the originating data source for the given reporting year; thus the reporting company was not able to provide data for this field to the source.
  3. If the company did not disclose at all to the source in a given year, the data value appears as “—”, and there is no source visible on the NZDPU.

There are many reasons a company’s reported emissions can change year-over-year (YOY), in addition to changes in absolute emissions. It is important to view emissions figures in context of their underlying methodologies, which can be referenced in the Methodology, Change in Calculation Methodology, and Exclusion sections in the Company Profile.

Many companies are using increasingly sophisticated and accurate methodologies to calculate their greenhouse gas emissions. Thus, YOY changes in reported emissions may be due to greater availability of data, more sophisticated calculation methodology, or a greater scope of business operations included in the calculations. Other events, such as mergers and acquisitions, may also result in YOY variances for a given company.
