NPI and NGER Reporting: What You Need to Know Before The Financial Year-End

As the end of the financial year approaches, two important compliance deadlines are just around the corner for companies in Australia: National Pollutant Inventory (NPI) and National Greenhouse and Energy Reporting (NGER).

Here’s everything you need to know to ensure you meet the deadlines.

What is NPI Reporting?

The National Pollutant Inventory (NPI) tracks pollutant substances from facilities across multiple industries that exceed the NPI reporting thresholds. Companies are required to report annually on emissions and waste transfers of the 93 NPI-listed substances.

The reporting thresholds are based on the amount of fuel used and the quantity of NPI-listed substances handled during the financial year.

Deadline: 30 September 2025

What is NGER Reporting?

The National Greenhouse and Energy Reporting (NGER) scheme requires companies to report on their greenhouse gas emissions, energy consumption, and energy production. Companies that exceed thresholds for energy consumption, production or emissions of CO2-e are required to submit an annual NGER report.

This reporting plays a crucial role in Australia’s efforts to reduce carbon emissions and track progress toward sustainability goals.

Deadline: 31 October 2025

Key Challenges to Watch Out For

  • Starting late: Both NPI and NGER submissions require detailed data collection. Rushing through the process can increase the risk of mistakes.
