The Repeal Net Zero Bill 2025 strips Australia’s statutory net‑zero architecture by repealing legislation and deleting statutory hooks that enabled emissions targets, market instruments for renewables, a net‑zero authority, and new vehicle efficiency standards. It also excises net‑zero language and functions from export finance and greenhouse reporting laws.
The change removes both policy instruments (statutory targets, guarantee‑of‑origin framework, vehicle standards) and the legal scaffolding that supported reporting, safeguards and financing decisions. That alters compliance duties, market signals used by corporate buyers and investors, and the authority of agencies that had new net‑zero mandates — with immediate legal effect on the day after Royal Assent unless other transitional steps are introduced.
At a Glance
What It Does
The bill repeals entire statutes and amends others to remove references, definitions and functions tied to net‑zero targets. It eliminates statutory guarantee‑of‑origin arrangements, a Net Zero Economy Authority, a new vehicle efficiency regime, and multiple safeguard and reporting provisions in the National Greenhouse and Energy Reporting framework.
Who It Affects
Large emitters and firms covered by greenhouse reporting and safeguard rules, renewable certificate and guarantees‑of‑origin markets, vehicle importers and manufacturers subject to efficiency standards, Export Finance and Insurance Corporation (EFIC) financing decisions, and regulators that relied on the repealed powers and definitions.
Why It Matters
Removing statutory architecture does more than reduce paperwork: it erases legal instruments that created market signals, enforcement tools, and investment criteria. That shifts where emissions are managed (from statute to non‑statutory policy or contract) and raises immediate questions about data continuity, existing credits and contractual arrangements tied to the repealed laws.

What This Bill Actually Does
The bill implements repeal and targeted amendment as its primary technique: it removes whole Acts listed in a schedule and strips definitions and provisions in other Acts that referenced net‑zero objectives. The schedule approach means the statutory deletions are direct — entire statutory regimes go away rather than being wound down over time under new transitional rules.
The bill’s commencement clause makes the Act effective the day after Royal Assent, so there is no built‑in long transition period in the primary text.
On markets and commercial architecture, the repeal of the guarantee‑of‑origin legislation and its charging act removes the statutory mechanism for issuing government‑backed renewable electricity certificates used in corporate procurement and tracking renewable supply. That removes a public certification and charging framework that market participants used to create value and to verify renewable attributes, leaving those functions to voluntary schemes, contract clauses, industry standards, or state arrangements unless replaced.The National Greenhouse and Energy Reporting (NGER) amendments go beyond cosmetic edits: the bill deletes multiple definitions, audit provisions and an entire part that underpinned the safeguard mechanism.
Practically, that means statutory descriptions of safeguard emissions, safeguard credit units, safeguard audits and related reporting constructs disappear from the federal reporting statute. The removal affects how emissions are measured, aggregated and enforced at the federal level and will interrupt the statutory continuity of greenhouse‑gas datasets and any trading or credit instruments that relied on them.The bill also carves net‑zero language out of Export Finance and Insurance Corporation provisions and the Future Made in Australia framework, including removing EFIC’s statutorily assigned net‑zero function and deleting references to the Paris Agreement in those contexts.
For EFIC and procurement frameworks, the effect is to narrow or eliminate climate‑related decision criteria embedded in statutory mandates — shifting the corporation’s legal decision space back toward non‑climate criteria unless its board or policy settings fill the gap.Finally, the bills remove the New Vehicle Efficiency Standard at the federal statutory level. That repeal eliminates the new, centrally mandated federal mechanism for setting fleet‑efficiency targets and compliance obligations for manufacturers and importers, potentially shifting the locus of vehicle emissions control to state rules, voluntary standards or the market unless replaced by other instruments.
The Five Things You Need to Know
The Act commences the day after it receives Royal Assent — the statute contains no extended federal transition period inside the primary commencement clause.
Schedule 1, Part 1 repeals entire Acts listed in the Schedule, including the Climate Change Act 2022, the Net Zero Economy Authority Act 2024, the Future Made in Australia (Guarantee of Origin) Act 2024 and the Future Made in Australia (Guarantee of Origin Charges) Act 2024.
The bill repeals the New Vehicle Efficiency Standard Act 2024, removing the federal statutory vehicle efficiency regime that would have imposed fleet or import compliance obligations.
The National Greenhouse and Energy Reporting Act 2007 is amended to remove multiple safeguard‑related definitions and provisions (including repeal of Part 3H and sections such as 22XB and 22XC), effectively dismantling the statutory safeguard architecture and its audit and crediting constructs.
The Export Finance and Insurance Corporation Act 1991 amendments repeal EFIC’s statutory ‘net zero’ function and related definitions (and repeal section 23B), removing legislated climate‑focused lending criteria and excising Paris Agreement references from EFIC’s statutory framework.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Commencement: immediate effect on Royal Assent
The Act specifies that the whole Act commences the day after Royal Assent. That timing means the repeals and amendments take effect immediately on the federal statutory timetable unless separate transitional instruments are issued under other powers. For practitioners, that creates an urgent planning horizon: contracts, regulatory filings and instrument issues that rely on the existing statutory regimes may be affected almost immediately.
Full repeal of core ‘net‑zero’ statutes
This Part repeals whole Acts identified in the schedule. Repealing an Act removes its substantive provisions, the offices and powers it established, and the statutory hooks for subordinate instruments created under it. For example, where a statute established an authority or program, repeal removes the authority’s statutory basis and its delegated legislative instruments lose their enabling head of power unless recreated elsewhere.
Strip net‑zero functions and Paris Agreement references from EFIC
The bill repeals definitions tied to Australia’s greenhouse gas targets and EFIC’s net‑zero function, and specifically repeals section 23B. Those edits remove statutory obligations or functions that directed EFIC to consider net‑zero transformation when making financing decisions. Consequence: EFIC’s statutory decision criteria narrow, and any previous requirement to factor net‑zero considerations into financing is legislatively removed — though EFIC could still adopt policy criteria voluntarily.
Collapse net‑zero streams in procurement framework; remove guarantee mechanisms
The bill excises net‑zero references from the Future Made in Australia Act and repeals the separate Guarantee of Origin and Charges Acts. It also narrows the National Interest Framework to only the economic resilience and security stream, removing the statutory net‑zero transformation stream. Practically, this removes a federal statutory pathway used to prioritize or certify low‑emissions goods and services for procurement and eliminates the federal guarantee‑of‑origin certification and charging model.
Dismantle statutory safeguard architecture and reporting hooks
The bill deletes numerous definitions (safeguard emissions, safeguard audit, safeguard credit unit, five‑year rolling averages, etc.), repeals Part 3H, and removes specific auditing and reporting subsections. Those changes do not merely alter terminology: they remove statutory constructs that made the safeguard mechanism operational, interferes with how certain emissions are defined and audited, and eliminates provisions that enabled crediting and safeguard outcomes under the federal reporting regime.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Large emitters and heavy industry: They lose statutory safeguard constraints and related reporting constructs that previously underpinned limits or crediting requirements, reducing federal compliance obligations and potential exposure to safeguard enforcement.
- Vehicle manufacturers and importers: Repeal of the federal vehicle efficiency statute removes a new federal compliance regime for fleet efficiency that would have created obligations or penalties for non‑compliant import volumes.
- Firms seeking deregulatory clarity: Companies that had been preparing for or budgeting for compliance with the newly enacted net‑zero statutes gain immediate relief from those forthcoming statutory obligations.
Who Bears the Cost
- Renewable‑energy developers and corporate renewable buyers: Repeal of the guarantee‑of‑origin and charges acts removes a government‑backed mechanism for certifying and monetizing renewable attributes, undermining a statutory pathway for revenue and verification used in corporate power purchase agreements.
- Regulatory agencies and data users: Government and private entities that rely on continuous NGER datasets and safeguard reporting face disruption; agencies must decide whether to maintain, reconfigure or fund new reporting arrangements to preserve continuity.
- Investors and markets seeking climate transparency: Removal of statutory reporting constructs and audit requirements reduces the quantity and legal standing of federal greenhouse‑gas data, increasing information risk for investors and lowering the enforceability of emissions claims built on federal datasets.
Key Issues
The Core Tension
The central dilemma: the bill trades away statutory tools designed to manage emissions and create predictable market signals in order to reduce or remove statutory obligations — but in doing so it eliminates the legal infrastructure that markets, regulators and contracts used to manage climate‑related risks and investments, leaving significant uncertainty about how those risks will be handled going forward.
The bill’s approach — wholesale repeal and deletion of definitions — creates immediate legal gaps that the primary text does not address. Repeal of an Act removes its head of power for subordinate instruments; without explicit transitional clauses, existing regulations, certificates, credits and contractual mechanisms that relied on those Acts become legally precarious.
The statutory deletions also create a web of orphaned references across other federal laws and instruments; those cross‑references may require consequential amendments or judicial interpretation to determine whether other regimes remain intact.
Another practical tension arises around data and contractual continuity. NGER deletions affect how emissions are defined, audited and aggregated.
Market contracts, safeguard credits and procurement clauses that used those constructs will face disputes over valuation and enforceability. The bill removes statutory mandates for EFIC and procurement frameworks to consider net‑zero factors, but it leaves open whether policy, procurement guidance or EFIC governance will voluntarily replace those criteria — an uncertain patchwork that could provoke litigation or lengthy administrative transition costs.
