New NGER Amendment Brings Biosolids-to-Biochar into National Reporting Scheme

25 August 2025

We are excited to share a landmark update from the Clean Energy Regulator — the National Greenhouse and Energy Reporting (NGER) Measurement Amendment (2025 Update) now includes biosolids-to-biochar as a recognised emissions reduction pathway.

Effective 1 July 2025 (for reports due 31 October 2026), wastewater operators can officially account for:

  • Tonnes of biosolids transferred to biochar production

  • COD (Chemical Oxygen Demand) in sludge diverted

  • Associated emissions reductions

Why this matters:

  • Elevates biochar’s commercial and environmental credibility

  • Enables water corporations, councils, and technology providers to meet regulatory requirements with confidence

  • Opens pathways for integration with ACCU carbon credit methodologies

“This latest development offers a structured, compliant means to demonstrate emissions reductions from biosolids reuse and circular economy practices.” - Don Coyne, CEO, ANZBIG
