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.

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:
    • Browsing lists of data fields by section
    • 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. At this time, downloading data is subject to the data source terms. See terms at https://nzdpu.com/terms-of-service.

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.

The Year in the source column is in reference to the CDP Disclosure year. For example, data disclosed by a company in CDP Disclosure 2023 would have a source of CDP Climate Change 2023.

The CDP questionnaire year is different from the ‘reporting year’ of emissions disclosed and may represent emissions from the prior calendar or fiscal year depending on the CDP questionnaire cycle for the year in question as companies define their disclosure period when reporting.

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

  • 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.
  • 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.
  • 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.

The NZDPU ingests data directly from data sources. The data that is currently available on NZDPU is from CDP. The NZDPU’s mission is to present company level data transparently and openly. Although the NZDPU takes some steps to standardize data presentation where feasible, the NZDPU does not alter company data ingested from third parties.

If a company notices that their data is incorrectly represented in their CDP disclosure or have any questions about the data reported to CDP, they should speak to their CDP account manager or raise a case via CDP’s Helpdesk.

The NZDPU ingests company data from each data source and uses publicly available sources to try and map company metadata to its applicable Legal Entity Identifier (LEI) in line with the Recommendations from the CDSC (see Global Legal Entity Identifier Foundation for more information about LEIs). If this mapping to LEI cannot occur due to a lack of publicly available information, then the NZDPU publishes the company name as disclosed to the data source (CDP, for the current release).

The NZDPU uses company disclosed International Securities Identification Number (ISIN) to map to the IFRS Sustainable Industry Classification System (SICS). If a company has not disclosed an ISIN or there is no mapping for a specific ISIN to a SICS sector then this field will show “Information not Available.” The NZDPU is working towards increasing this coverage.

Organizational boundaries define the scope of the entities (e.g., subsidiaries, joint ventures) and assets included within a reporting company’s GHG emissions inventory. These boundaries are foundational to emissions accounting, akin to the principle of consolidation in financial reporting. Given the variation that exists in legal and organizational structures across companies, organizational boundaries are essential for understanding the businesses and activities that constitute the company for GHG emissions accounting purposes.

The Greenhouse Gas Protocol defines three standard approaches for consolidating GHG emissions: equity-share, operational control and financial control. Under equity share, a firm accounts for emissions in proportion to its share of equity in operations, whereas under the control approaches, a firm accounts for 100% of the emissions from any operations it operationally or financially controls, respectively. These approaches are the most globally used and recognized for defining an organization's GHG emissions responsibility, and provide a common framework for comparing company emissions disclosures.

When a company does not disclose an organizational boundary or does not align with one of the standard GHG Protocol boundaries above, the NZPDU displays an icon to alert users that this data may not be comparable or to take consideration when conducting comparisons with these disclosures. For emissions data disclosed without any organizational boundary at all, it is not possible to determine the scope of inclusion of the reporting entity’s business activities in the GHG inventory, affecting comparability with other companies’ disclosures as well as the entity's own past disclosures. Meanwhile, although uncommon, some companies do report emissions using alternative, non-GHG Protocol-aligned boundaries that they themselves have uniquely defined. With sufficient contextual information, the inventories of these companies can be understood, but the unique nature of the boundaries without standard definitions means that comparability to other disclosures is impacted.

In the case of emissions intensity reduction targets, companies must specify the metric used by the reporting entity to measure their GHG emissions intensity. Whilst there are standard intensity metrics that are used by most companies, some of which are sector-specific and some of which are cross-cutting, the significant variation among business activities means that some companies choose to report bespoke metrics that specifically reflect their operations. Currently these non-standard metrics are reported as open-text entries in the original data source from which the NZDPU directly ingests company data (CDP).

Although the NZDPU does take some steps to standardize data presentation where feasible, the NZDPU does not edit the data it receives and cannot assume what the ‘correct’ units might be. Therefore, the intensity units are generally published as reported even if they do not conform to the definition of an intensity metric. Common types of errors include:

  • No weight measurement attributed to the gas in the numerator – only ‘CO2’ or ‘CO2e’ is written with no indication of whether this numerator is in grams, kilograms, tonnes etc.
  • The denominator is not a concrete, measurable activity – a common example is just a currency being given as a denominator with no noun attached to indicate the activity that the currency represents, e.g., revenue, profit, sales etc.
  • A non-specific denominator can also mean that it is not possible to determine whether the target is a physical or economic intensity target. In this case, the ‘Target intensity type’ field will be rendered as null on the NZDPU.
  • The target reported is an absolute target with no denominator disclosed to normalize the emissions, or the denominator is entered as ‘per year’.
  • Multiple units are reported, often multiple denominators. Whilst these units might be valid intensity metrics, as only one set of target data is reported alongside them, it cannot be determined which of the intensity metrics the reported values represent.
