What is NZ CS and who must report under it?

NZ CS refers to the Aotearoa New Zealand Climate Standards (NZ CS 1, NZ CS 2, NZ CS 3) issued by the External Reporting Board (XRB). Large listed issuers, banks, insurers, and investment managers with over $1 billion in assets are required to make climate-related disclosures under NZ CS for financial years starting on or after 1 January 2023.

How many NZX companies currently report emissions data?

Based on available public disclosures, 87 of approximately 130 NZX-listed companies have reported emissions data (Scope 1, 2, or 3). This figure may change as more companies begin reporting under the NZ CS framework.

What ESG data does NZXplorer track?

NZXplorer tracks emissions (Scope 1, 2, and 3 in tonnes CO2-e), net-zero targets, board and workforce diversity metrics, workplace safety indicators (LTIFR, TRIFR), and reporting framework compliance (GRI, TCFD, SBTi, UN SDGs) across NZX-listed companies, based on data from annual reports and public disclosures.

What is TCFD and why does it matter for NZ companies?

The Task Force on Climate-related Financial Disclosures (TCFD) is an international framework for climate risk reporting. New Zealand's NZ CS standards draw heavily on TCFD recommendations. Companies that are TCFD-compliant are generally better positioned for NZ CS compliance.

Can I access NZX ESG data via API?

Yes. NZXplorer provides a public API endpoint at /api/v1/esg/:ticker/xbrl that returns structured ESG and climate disclosure data tagged with the NZ CS taxonomy. Developers can integrate this data into their own tools and models.
