Scope 3 emissions management software for value chain transparency
NZC Portal provides Scope 3 emissions management software for operating companies required to measure, manage, and disclose value chain emissions in line with the GHG Protocol and Science Based Targets initiative (SBTi).
The platform supports structured Scope 3 inventories, data quality management, and repeatable reporting across complex organisations.

Identify material Scope 3 categories
Improve data quality over time
Engage suppliers and value chain partners
Produce credible, auditable disclosures
NZC Portal provides a single system to manage Scope 3 emissions beyond spreadsheets and one-off exercises.
