The Australian government will enable companies to report scope 1 emissions from the consumption of biomethane and hydrogen, which will need to be backed by eligible renewable gas certificates, it announced today.
Companies will be able to prove that the gas they receive from the natural gas network and consume in a reporting year contains an amount of renewable gas, as represented by renewable gas certificates retired or completed by them or on their behalf, adjusted for losses, the Department of Climate Change, Energy, the Environment and Water (DCCEEW) said on 13 June.
The new product guarantee of origin (PGO) certificates registered under the guarantee of origin (GO) scheme, as well as the renewable gas guarantee of origin (RGGO) certificates issued under the GreenPower Renewable Gas Certification (RGC), will both be allowed.
Any gas sourced from the natural gas network that is not covered by the new certificate-backed loss-adjusted amount must be reported as natural gas, the DCCEEW said.
The changes are part of updates to the National Greenhouse and Energy Reporting (NGER) scheme, which is used to measure and report greenhouse gas (GHG) emissions and energy production and consumption. These are the latest changes following the implementation of the recommendations made at the end of 2023 by Australia's Climate Change Authority (CCA), which reviews the NGER scheme every five years.
The market-based reporting allowing companies to report the scope 1 emissions benefits from their renewable gas purchases will start from 1 July 2025, and be applicable from the July 2025-June 2026 financial year onwards. They will affect NGER scheme reports to be submitted by corporations by 31 October 2026.
The updates also include amendments to support the reclassification of hydrogen as a fuel type. Hydrogen was previously classified in the NGER scheme as an energy commodity.
The DCCEEW will monitor the uptake of biomethane as a feedstock for ammonia and hydrogen production and may revisit some technical rules in future annual NGER scheme updates, it said.
Potential impact on oil and gas facilities
Other changes announced on 13 June include updates to the emission factors used in two methods for gas flared in oil and natural gas operations. Some submissions to a public consultation raised concerns about the potential overestimation of methane emissions resulting from the assumption that flare gas is 100pc methane, and implications of the proposed emission factors on facilities covered by the safeguard mechanism, the DCCEEW said.
The Clean Energy Regulator has the discretion to vary the facility's baseline to accommodate the regulatory change if the revised factors have a material impact on emissions reported by a facility covered by the safeguard mechanism, it said.
Facilities under the oil and gas extraction sector received a combined 3.07mn safeguard mechanism credits (SMCs) in the July 2023-June 2024 financial year as their covered scope 1 emissions were below their baselines.
