Significant recent changes to the Australian Standards and National Greenhouse Energy and Reporting (NGER) Scheme will deliver major advantages for Delorean’s supply of renewable gas in Australia.

The changes formally recognise Delorean’s biomethane as a natural gas equivalent and
enable companies to use Renewable Gas Guarantee of Origin (RGGO) certificates for injected biomethane to reduce their Scope 1 emissions.

NGER Scheme — Emissions Reporting Reform

• Biomethane and hydrogen are formally recognised as new fuel types under the
  Measurement Determination, supporting market-based emissions accounting.
• From the 2025–26 reporting year, companies using RGGO certificates for injected
  biomethane will be able to reduce their Scope 1 emissions, with first reports due by
  31 October 2026.

AS 4564:2025 — Recognition of Renewable Gas

• As of 12 June 2025, AS 4564:2025 has officially been released, expanding the standard to include “natural gas equivalents” such as biomethane and hydrogen.

These regulatory changes provide long-awaited certainty, reduce investment risk, and
support accelerated commercial project rollout.
