Key statutory terms are defined in s 4 and determine how obligations and accounting will work. Eligible offset is defined by reference to regulation, with separate prescriptions potentially applying when determining net emissions attributable to Western Australia and when determining net emissions attributable to the State Government (s 4(1)). Emissions means greenhouse gas emissions into the atmosphere, and greenhouse gas itself is defined by reference to the Commonwealth National Greenhouse and Energy Reporting Act 2007, s 7A (s 4(1)). Removals means removals of greenhouse gases from the atmosphere (s 4(1)). The mitigation hierarchy is given a short definition as a preference for reducing emissions over relying on removals and for offsetting only as a last resort (s 4(1)). Those definitional choices shape how the Minister must approach eligible offsets and the sequencing of measures when preparing strategies and making determinations (see s 8(4), s 10(5), s 12(2)(d)).

The Bill distinguishes between Western Australia’s targets and the State Government’s targets. Western Australia’s long‑term target is net zero by 2050 (s 7). Interim targets for Western Australia must be set by the Minister for five target years (s 8(1)-(2)), and each interim target must include (except for 2050) a percentage reduction relative to 2005, an emissions budget covering the target year and the four prior years, and the extent to which eligible offsets can be taken into account (s 8(3)(a)-(c)). The State Government’s long‑term target mirrors the jurisdictional target, a net zero goal by 2050, but the baseline year for Government interim percentage reductions is 2020 rather than 2005 (s 10(1)-(4)). The Government interim target for 2030 is required as soon as practicable, while other Government targets are tied directly to the Commonwealth’s communication of Australia’s nationally determined contribution under Article 4.9 of the Paris Agreement (s 10(3)). For Western Australia’s interim targets the Minister must set targets as soon as practicable after the Commonwealth communicates Australia’s nationally determined contribution (s 8(2)).

Net emissions attributable to Western Australia and to the State Government are matters the Minister must determine for the purposes of the Act (s 11(1)). In doing so the Minister must calculate the balance of emissions and removals attributable to Western Australia and may take into account eligible offsets to the extent consistent with the applicable target (s 11(2)). For the State Government the Minister must determine the emissions attributable to the State Government and may take into account eligible offsets consistent with the Government target (s 11(3)). The Bill therefore treats “net emissions” as an administrative construct determined by the Minister, rather than a formula fully prescribed in primary legislation; the methodology is required to be published in the annual climate change report (s 25(3)(b)).

Strategic instruments are central. The emissions reduction strategy must be prepared within three years and must enable target achievement, support transition to net zero, identify feasible strategies, mitigation options and implementation pathways, assess costs and resource allocation, and “aim to cover all major sources of emissions attributable to Western Australia” (ss 12-13). The climate adaptation strategy has an analogous structure and must include a summary of climate implications, responsibilities, time frames, and key performance indicators for monitoring effectiveness (ss 16-18). Sector adaptation plans must be prepared by responsible Ministers nominated by the Minister, cover specified sectors, and identify potential impacts, likelihoods, severity and costs, policies and measures, time frames, responsibilities and KPIs (ss 20-24). Public consultation and a summary of submissions are required when preparing or reviewing the strategies and plans (ss 15(1)-(2); 19(1)-(2); 24(1)-(2)).

Reporting is specified. The Minister must prepare an annual climate change report within six months of each financial year end, make it publicly available and lay it before Parliament (s 25(1)). The report must include the Minister’s determination of net emissions, the methodology including which eligible offsets were taken into account and their contribution, progress in implementing the emissions reduction strategy and any other matters the Minister considers appropriate (s 25(2)-(3)). The Minister may provide preliminary determinations and revise them in later reports (s 25(4)).

Finally, the Act contemplates delegated detail by regulation, including what counts as prescribed matters and eligible offsets, and it establishes a five year review cycle for all the major instruments and the Act itself (ss 26-27; ss 14(1), 18(1), 23(1)).

Primary decision makers. The Bill places principal decision‑making powers, duties and responsibilities on the Minister. The Minister must set interim targets, determine net emissions for the State and jurisdiction, prepare the emissions reduction strategy and climate adaptation strategy, consult publicly, prepare the annual climate change report and review the operation and effectiveness of each strategy and the Act (see ss 6, 8, 11, 12-15, 16-19, 25, 27). The Minister may also nominate other Ministers as responsible Ministers for sector adaptation plans, subject to prior consultation with the Premier (s 21(1), (3)). Those responsible Ministers must prepare sector adaptation plans and carry the review and publication duties for those plans (ss 22-24). The Governor retains regulation‑making authority under s 26.

State Government entities. The Act specifically covers the State Government as a subject of obligations and targets. State Government is defined to include each department of the Public Service, each GTE as defined, and any State entity declared by the Minister by Gazette notice to be part of the State Government for the purposes of this Act (s 4(1), definition of State Government). Consequently departments, GTEs (including statutory bodies established under the Electricity Corporations Act 2005, Port Authorities Act 1999, Water Corporations Act 1995 and Western Australian Land Authority Act 1992 as identified in the GTE definition at s 4(1)) and declared State entities will be the units whose emissions are to be assessed when the Minister determines net emissions attributable to the State Government (s 11(3)). The Bill therefore creates a reporting and target architecture that directly affects the internal operations of the public sector, imposing data collection and asset management expectations consistent with preparing the required determinations and strategies (ss 11, 12, 16, 22).

Private sector and communities. The Bill is framed around ministerial instruments, reporting and strategies. It does not create direct statutory obligations on private sector entities to reduce emissions in the main text. However the Bill explicitly contemplates engagement with sectors and participants: sector adaptation plans aim to increase awareness and capacity of participants in each sector and to facilitate collaboration between government, private and community participants to identify and implement policies and measures (s 20(1)(a)-(c)). Public consultation requirements for strategies and plans are statutory, and those preparing plans must have regard to a summary of written submissions (ss 15(1)-(2), 19(1)-(2), 24(1)-(2)), which gives private actors and community groups procedural channels to influence the strategies. Businesses and community groups that participate in consultations can therefore affect policy content, timing and responsibilities.

Who pays. The Bill does not create a defined levy, price mechanism or penalty regime. The principal costs created by the Bill are administrative and budgetary. Government departments, GTEs and declared State entities will bear the direct costs of data collection, reporting, emissions accounting, participation in strategy development and implementation of measures to meet State Government targets. The Minister is required to consider resource allocation in preparing strategies and plans (ss 13(2)(c), 17(2)(c), 22(2)(c)), which implies a need to allocate state funds to implementation, monitoring and adaptation measures. Private sector costs are contingent: if strategies and sector plans recommend or require new regulatory measures, procurement changes, infrastructure investment, or participation in eligible offset mechanisms prescribed by regulation, private actors will incur costs then. But the Bill itself does not set those private costs; it creates structures by which such measures could be developed and later implemented.

Who decides. The Minister decides interim targets, whether to amend them in exceptional circumstances, which eligible offsets can be taken into account and the methodology for net emissions determinations (ss 8, 9, 11). The Governor decides regulations, including which offsets are prescribed (s 26). The Minister nominates responsible Ministers for sector plans after consulting the Premier (s 21). Parliament’s role is oversight: the Minister must lay notices and all strategies, plans and annual reports before both Houses (various provisions), enabling parliamentary scrutiny.

Principal ministerial duties. The Minister is given an express set of functions, including promotion of action to meet Western Australia’s emissions reduction targets, development and promotion of policies, programs and measures to reduce net emissions consistent with the mitigation hierarchy, assessment of climate impacts, and development of adaptation measures (s 6(a)-(d)). The Minister must prepare an emissions reduction strategy before the third anniversary of Royal Assent, be satisfied that it will enable targets to be met and support the transition to net zero, lay it before Parliament and make it publicly available (s 12(1)-(5)). The Minister must similarly prepare a climate adaptation strategy before the fifth anniversary, with parallel publication and laying obligations (s 16(1)-(4)). The Minister must also prepare annual climate change reports within six months of year end (s 25(1)) and conduct statutory reviews of the strategies at intervals not exceeding five years (ss 14(1), 18(1)). The Minister must determine net emissions attributable to Western Australia and to the State Government, including the balance of emissions and removals and the extent to which eligible offsets are taken into account, consistent with the targets (s 11).

Responsible Ministers’ duties for sector plans. The Minister must nominate responsible Ministers for each listed sector, after consulting the Premier, and may nominate multiple Ministers where appropriate (s 21(1)-(5)). Those responsible Ministers must prepare, publish and lay before Parliament sector adaptation plans as soon as practicable, consider costs and resource allocation, and review plans every five years (ss 22-23). They must consult publicly when preparing or reviewing such plans and have regard to a summary of written submissions (s 24).

Consultation and publication duties. The Minister and responsible Ministers must consult publicly when preparing or reviewing the emissions reduction strategy, the climate adaptation strategy and sector adaptation plans, and must have regard to summaries of submissions which must include written submissions received (ss 15(1)-(2), 19(1)-(2), 24(1)-(2)). The Bill mandates public availability for the major instruments and requires that instruments be laid before each House of Parliament, with limited carve outs for minor or technical amendments (see ss 12(3)-(4), 16(2)-(3), 22(3)-(4)).

Decision constraints and procedural duties. The Minister must set interim targets as soon as practicable after the Commonwealth communicates Australia’s nationally determined contribution under Article 4.9 of the Paris Agreement (s 8(2)), and the Minister must be satisfied that each interim target represents progression beyond any previous interim target (s 8(6)). The Minister may amend an interim target only upon satisfaction of exceptional circumstances and must publish reasons when amendments are made (s 9). The Minister must take into account the mitigation hierarchy when setting how eligible offsets may be counted (s 8(4); s 10(5)). The bill requires the Minister to determine net emissions and permits consideration of eligible offsets "to the extent consistent with the emissions reduction target" (s 11(2)(b), (3)(b)), which situates offset usage as an element subject to Ministerial judgement and target consistency.

Rights and remedies. The Bill creates procedural rights for participation in public consultation and for access to published strategies, plans and reports. It creates no express private right of action, no statutory cause of action for non‑performance, and no criminal sanctions set out in the text. Remedies therefore are likely to be political and administrative, including parliamentary scrutiny and public disclosure via mandatory publication and laying obligations. The Act binds the Crown (s 5), which gives statutory effect to its duties across public bodies, but does not specify enforcement measures or sanctions for non‑compliance by Ministers or agencies.

Regulatory and delegated powers. The Governor may make regulations prescribing matters required or permitted by the Act and anything necessary to give effect to the Act’s purposes (s 26). The Act therefore anticipates that technical details, including definitions of eligible offsets for different purposes, emissions accounting rules and related administrative requirements, will be supplied by regulation, which will in turn shape duties and potential obligations for entities affected.

The Bill contains no express civil penalties, criminal offences or administrative sanctioning provisions in its text for failure to comply with duties, targets or publication requirements. The enforcement architecture is procedural and disclosure based. Accountability mechanisms provided in the Bill include publication obligations, parliamentary laying requirements, public consultation duties, statutory reviews and the requirement that the Minister produce annual reports including the methodology and offsets used in net emissions determinations (see ss 12(3)-(5); 16(2)-(4); 22(3)-(5); 25(1)-(4); 14(1)-(2); 18(1)-(2); 23(1)-(2); 27(1)-(2)).

Consequence of absent penalties. Because the Act does not create express monetary penalties, prosecutions or regulatory sanctions, the primary mechanisms for enforcing compliance will be political, administrative and reputational. Public disclosure obligations mean that non‑performance can be exposed to parliamentary scrutiny through laid documents, to public scrutiny through publication requirements and to media and stakeholder pressure. The Act also requires the Minister to publish reasons if target amendments are made under exceptional circumstances (s 9(2)), which increases transparency but does not create an enforcement remedy against the Minister.

Delegated regulation as a potential enforcement source. The Act empowers the Governor to make regulations necessary or convenient to give effect to the Act (s 26). Regulations could, subject to parliamentary oversight, create specific compliance duties or penalties, or establish registries, reporting templates and auditing requirements. However the Bill as drafted leaves those powers prospective; the text of the Bill itself does not provide for any specific enforcement instrument beyond reporting and review obligations.

Administrative accountability pathways. The Bill creates administrative duties that may be actionable through other institutional channels. For State Government entities, the statutory duty to be part of the State Government accounting architecture (s 4(1), definition of State Government) means their emissions are to be determined by the Minister (s 11). Non‑compliance by public sector bodies with internal directives or resource allocations arising from strategies could trigger internal public sector accountability, budgetary consequences or ministerial questions in Parliament. The Act therefore channels accountability primarily through governance, transparency, and political oversight rather than through statutory penalties.

References to Commonwealth law and international treaty. The Bill adopts the Commonwealth definition of greenhouse gas by reference to the National Greenhouse and Energy Reporting Act 2007, s 7A (s 4(1)). The timing for setting interim targets is tied to the Commonwealth communication of Australia’s nationally determined contribution under Article 4.9 of the Paris Agreement; the Bill explicitly links the timing of the Minister’s duties to that Commonwealth process for both Western Australia’s interim targets and the State Government’s interim Government targets (ss 8(2); 10(3)). The Bill therefore embeds an intergovernmental linkage: the State’s interim target setting is formally triggered by a Commonwealth obligation or communication under the Paris framework, which the Bill references.

Interaction with statutory GTEs and State entities. The Bill’s definition of GTE cross‑references other Western Australian legislation, listing bodies corporate established under the Electricity Corporations Act 2005, the Port Authorities Act 1999, the Water Corporations Act 1995 and the Western Australian Land Authority Act 1992 as examples of GTEs (s 4(1)). The definition of State Government includes departments, GTEs and any State entity declared by the Minister by Gazette notice (s 4(1)). That structure draws those existing statutory entities into the reporting and target architecture. The Bill does not, however, displace the powers and duties those Acts create for the statutory corporations themselves; it instead requires their inclusion in State Government accounting for the purposes of this Act.

Regulations and delegated detail. The Governor’s power to make regulations under s 26 is broad, covering matters required or permitted by the Act and anything necessary or convenient to give effect to the Act’s purposes. As a consequence, the Act anticipates that technical emission accounting rules, the definition of eligible offsets, reporting forms and perhaps procedural obligations (for example auditing or verification requirements) will be provided by regulation. Those regulations would operate alongside other relevant state and Commonwealth law and could create more prescriptive obligations for private and public sector entities.

Absence of express inconsistency clause. The Bill does not include an express clause dealing with inconsistency between this Act and other State laws, nor a declaration of inconsistency with Commonwealth law. Standard constitutional limits apply. The Bill binds the Crown in right of Western Australia and, so far as legislative power permits, the Crown in all other capacities (s 5). Any inconsistency issues between State and Commonwealth law will therefore be resolved by the ordinary rules of constitutional law rather than by express statutory conflict‑resolution provisions within the Bill.

Potential reliance on Commonwealth reporting frameworks. The Bill requires the Minister to determine net emissions and to publish methodology (s 11; s 25(3)(b)) but does so in the context of taking definitions and international triggers from Commonwealth sources. That design suggests that the Minister’s determinations and reporting are likely to be aligned with, or at least cognisant of, Commonwealth reporting regimes such as the National Greenhouse and Energy Reporting scheme, though the Bill leaves the precise technical alignment to Ministerial methodology and regulation rather than prescribing a single mandatory Commonwealth instrument.

Parliamentary oversight. The Bill embeds statutory laying requirements for targets, strategies, plans, notices and the annual climate change report (see ss 8(7), 12(3), 15(3), 16(2), 19(3), 22(3), 23(3), 25(1), 27(2)). Those provisions create specific interaction points between executive action under the Act and parliamentary scrutiny, which can operate in combination with other legislative oversight powers.

The text provided is of the Climate Action this Decade Bill 2025 as introduced in the Western Australian Legislative Council by Hon. Dr Brad Pettitt, MLC. The Bill itself contains no recorded amendments, transitional provisions or amendment history within the text supplied. The Bill as drafted provides internal mechanisms for later change and review.

Statutory amendment mechanisms within the Bill. Interim targets may be amended by the Minister if the Minister is satisfied exceptional circumstances justify the amendment, and the Minister must publish reasons and lay the amending notice before Parliament (s 9(1)-(2)). The Minister may also amend or replace the emissions reduction strategy, the climate adaptation strategy and sector adaptation plans; there are statutory review cycles requiring the Minister or responsible Ministers to review the relevant instruments within five years of first publication and then at intervals not exceeding five years, and to decide whether to amend or replace the instruments or that they need not be changed (ss 14(1)-(2); 18(1)-(2); 23(1)-(2)). The Act itself must be reviewed by the Minister as soon as practicable after the fifth anniversary of the section coming into operation and then at intervals not more than five years, with the Minister to lay a report before each House (s 27(1)-(2)). Those internal review and amendment provisions are the Bill’s designed mechanism for evolving policy and implementation in light of changing circumstances.

Regulatory amendment. The Bill delegates considerable detail to regulations and provides a broad power for the Governor to make regulations to prescribe all matters required or permitted by the Act or necessary or convenient for giving effect to its purposes (s 26). The content of regulations, once made, will form a practical part of the amendment and implementation pathway because regulations may define eligible offsets, prescribe other technical accounting matters and specify forms or processes for consultation and publication. Any change in the regulatory instruments will therefore operationally amend how the Act works without requiring primary legislative amendment.

No historical amendments recorded. As the Bill is presented in its introduced form, there is no recorded prior statutory amendment history, no transitional or saving provisions, and no retrospective amendments noted in the text. The Bill does not contain provisions that retrospectively alter past determinations; it allows the Minister to set interim targets and to publish determinations prospectively, and to revise preliminary determinations in subsequent annual reports (s 25(4)).

The Bill text does not identify any judicial decisions, tribunals or litigation history. There are no case citations, no references to judicial interpretations, and no mention of past litigation under this instrument because it is presented as proposed legislation. The defined terms note references other Acts such as the National Greenhouse and Energy Reporting Act 2007 for the definition of greenhouse gas (s 4(1)), but the Bill does not invoke any reported cases, nor does it reference past determinations that have been litigated.

Potential litigation pathways. Because the Bill creates duties on Ministers, requirements to publish and lay documents before Parliament, and public consultation obligations, litigation could hypothetically arise in the future over failures to comply with procedural obligations, the adequacy of consultation, or the lawfulness of a Minister’s determinations or regulatory instruments. However the Bill contains no private right of action, no express statutory cause of action for non‑performance, and no specified review or appeal mechanism for Ministerial determinations within its text. Any legal challenge would therefore rely on general administrative law grounds such as legality, procedural fairness or review of unlawful exercise of power, and be shaped by the common law and any applicable State judicial review statutes. The Bill itself does not establish those judicial review mechanisms, and no litigation history is supplied in the Bill.

Absence of precedent in the Bill. The Bill’s silence on litigation means practitioners should assume standard administrative law remedies and constitutional constraints apply, but any specific judicial treatment of the Act, its instruments or related regulations will depend on future fact patterns and legal challenges. Practitioners should monitor the development of regulations and Ministerial determinations because those instruments will generate the practical legal questions that could lead to litigation.

Ministerial discretion concentrated, with procedural but not substantive constraints. The Bill vests significant discretion in the Minister to set interim targets, determine net emissions, and specify how eligible offsets are counted (ss 8, 11). The Act imposes constraints that are procedural and qualitative, for example that the Minister must take into account the mitigation hierarchy (s 8(4); s 10(5); s 12(2)(d)) and must be satisfied that each interim target represents a progression beyond any previous target (s 8(6)). Those statutory constraints are not expressed as rigid formulas. Practically, that means the Minister has room to shape offset inclusion, accounting conventions and emissions budgeting within the bounds of “consistency with the emissions reduction target” and the mitigation hierarchy (s 11(2)(b)-(3)(b)). The Act does not prescribe detailed accounting rules in primary legislation; methodology is left to the Minister and must be disclosed in the annual report (s 25(3)(b)). Parties should note that discretionary determinations are subject to administrative law review principles rather than fixed statutory formulas.

Eligible offsets are defined by regulation and treated differently for Western Australia and the State Government. The Act defines eligible offset as an offset prescribed for the specific purpose of determining net emissions attributable to Western Australia or to the State Government (s 4(1)). That creates two potential regulation classes, which may not be identical. The Act requires the Minister to take into account the mitigation hierarchy when setting the extent eligible offsets can be applied (s 8(4); s 10(5)). The practical effect is that offset rules, supply, eligibility and vintage will be governed by delegated instruments rather than the Act itself, and the Minister’s published methodology and annual report must disclose which offsets were counted and their contribution (s 25(3)(b)). Stakeholders should therefore watch regulatory instruments closely since they will determine the practical scope of offsetting.

Emissions budgets and baselines differ between Western Australia and the State Government. For Western Australia, interim targets other than 2050 must state percentage reductions relative to 2005 and include an emissions budget covering the target year and the four preceding years (s 8(3)(a)-(b)). For the State Government, percentage reductions are relative to 2020 and, other than for 2030, the interim Government target must include an emissions budget covering the target year and four preceding years (s 10(4)(a)-(b)). The Government target for 2030 is required “as soon as practicable” and is not required to include a five year emissions budget (s 10(3)-(4)(b)). That asymmetry may affect the timing and stringency of initial State Government accounting versus broader jurisdictional accounting.

No statutory penalties. The Bill contains no fines, enforcement sanctions, or express private rights of action for failure to meet targets or to comply with statutory duties. Accountability is achieved through publication, laying before Parliament and statutory reviews (ss 12(3), 16(2), 22(3), 25(1), 27). For entities seeking direct legal sanctions, the absence of penalty provisions is a structural limitation. Disputes will therefore tend to be political, administrative or judicial review claims rather than enforcement proceedings under the Act.

“Public consultation” and “have regard to” phrasing. The Minister and responsible Ministers must consult publicly and have regard to a summary of submissions, including written submissions (ss 15(1)-(2); 19(1)-(2); 24(1)-(2)). The statutory test is to have regard to the summary; there is no requirement to adopt recommendations, to provide individual responses to submitters or to conduct formal, deliberative consultation beyond the summary requirement. That will matter in any challenge about the adequacy of consultation. The Bill provides transparency through the requirement to include the written submissions in the summary, but it does not prescribe minimum consultation standards, timeframes or mandatory substantive responses.

Timelines are soft. Many timetables use “as soon as practicable” rather than fixed deadlines. The Minister must set interim targets for target years “as soon as practicable” after the Commonwealth communicates Australia’s nationally determined contribution (s 8(2)), must set the Government 2030 target “as soon as practicable” (s 10(3)(a)), and sector adaptation plans must be prepared “as soon as practicable” (s 22(1)). The emissions reduction strategy has a firmer deadline of before the third anniversary and the climate adaptation strategy before the fifth anniversary of commencement (ss 12(1), 16(1)). The “as soon as practicable” language can introduce uncertainty about exact timing and create potential political pressure points rather than enforceable statutory deadlines.

Reporting may include preliminary determinations. The Minister may publish a preliminary determination of net emissions in the annual report and revise that determination in a subsequent report (s 25(4)). That permits iterative accounting but also creates potential volatility in reported performance and inferences about whether targets are being met. Stakeholders and analysts should therefore not assume initial figures are final; the Bill explicitly allows revision.

Regulations will determine many practical realities. Because the Act defers eligible offsets and other detailed matters to regulations (s 4(1) definition; s 26), the effective rules on offset types, verification, additionality and accounting boundaries will be set later. The Act therefore sets up a two‑stage process: high level targets and procedural duties in primary legislation, with technical and operational rules to be developed by regulation and Ministerial methodology. That split increases the importance of monitoring the regulation‑making process and the content of annual methodology disclosures.

For Ministers and government agencies. Build a governance timetable and data architecture immediately upon Royal Assent. The emissions reduction strategy must be prepared within three years and the climate adaptation strategy within five years (ss 12(1), 16(1)), and sector adaptation plans must be prepared by responsible Ministers “as soon as practicable” after nomination (s 22(1)). To meet those statutory deadlines, relevant agencies should inventory emissions sources and removals across departments and GTEs, establish data collection, define boundary rules consistent with anticipated regulations, and design methodologies that can be justified as consistent with the mitigation hierarchy. Agencies should also prepare resource estimates because the Minister must consider resource allocation when preparing strategies and plans (ss 13(2)(c), 17(2)(c), 22(2)(c)). The Minister’s annual report must disclose the methodology and offsets relied upon (s 25(3)(b)), so agencies should ensure that accounting and verification processes are documented and auditable.

For State Government bodies, GTEs and declared State entities. Recognise that your emissions will be included in the State Government target accounting unless specifically excluded; the definition of State Government includes departments, GTEs and Ministerially declared State entities (s 4(1)). Those bodies should start internal emissions accounting, set internal reduction plans and engage with the Minister’s office to ensure the Minister’s determinations reflect accurate data. Because eligible offsets are to be prescribed and their use must be taken into account consistently with targets, public bodies should build capacity to evaluate offset quality and to participate in any prescribed offset registry or market once regulations are made.

For responsible Ministers preparing sector adaptation plans. Nomination requires prior consultation with the Premier (s 21(3)). Upon nomination, responsible Ministers must prepare sector adaptation plans that identify impacts, likelihoods, severity and costs, set out policies and time frames, and include KPIs for monitoring (s 20(2)). They must consult publicly and include summaries of written submissions (s 24(1)-(2)). Practical compliance steps include scoping stakeholder lists, drafting consultation materials, establishing timelines for KPIs, modelling sectoral impacts and costs, and coordinating cross‑agency inputs for resource allocation considerations (s 22(2)). Responsible Ministers must lay plans before both Houses and ensure public availability (s 22(3), (5)).

For private sector participants and community groups. Engage in the statutory consultations for strategies and sector plans, provide written submissions so they will be included in the required summaries, and participate in policy development forums. While the Bill does not impose direct statutory obligations on private businesses in its primary text, sector adaptation plans are expressly designed to increase the capacity of participants and to facilitate collaboration between government, private and community actors (s 20(1)(b)-(c)). Businesses should therefore prepare to respond to recommended measures and to the technical detail that will appear in regulations and Ministerial methodologies, including possible future requirements on offsets, procurement, or reporting.

For auditors, accountants and compliance professionals. Anticipate that the Minister’s methodology for net emissions will be described in the annual report (s 25(3)(b)). Prepare to assist public bodies and large private actors in aligning their internal accounting systems with the Minister’s approach; that will likely involve reconciling boundaries, scopes, treatment of removals, and offset accounting once regulations identify eligible offsets. Establish audit trails and documentation that enable transparent disclosure, since the Act requires public availability of strategies, plans and the annual report, and requires inclusion of written submissions in consultation summaries (ss 12(5); 16(4); 25(1); 15(2), 19(2), 24(2)).

For Parliamentarians and oversight bodies. Use the statutory laying and publication obligations to monitor progress. The Minister must lay interim targets, strategies, plans and annual reports before each House as soon as practicable after making them (e.g. ss 8(7), 12(3), 16(2), 22(3), 25(1)). Parliamentary committees should develop processes to evaluate the Minister’s methodology disclosed in annual reports, and to examine whether strategies and plans set clear responsibilities, time frames and KPIs as required by the Act (ss 13(3)(b); 17(3)(c)-(d); 20(2)(c)-(e)).

Operational checklist summary. Immediate steps to comply and prepare include: set up an interagency emissions data working group; map organisational boundaries to the State Government definition; draft preliminary methodological approaches for greenhouse gas accounting and removals consistent with the mitigation hierarchy; plan public consultation programs and documentation for s 15, s 19 and s 24 processes; prepare template KPIs, time frames and resource allocation plans for strategies and sector plans; and establish internal schedules so statutory review cycles and laying obligations can be met. Monitor regulation‑making under s 26 closely, because regulations will define eligible offsets and other technical obligations that will materially affect implementation.

Limitations on compliance obligations. Note that the Bill imposes no criminal penalties and no automatic private enforcement mechanism; compliance is therefore focused on meeting disclosure, planning, and public consultation duties and on aligning administrative processes with Ministerial determinations and regulations. Entities should therefore prioritise transparency, documentation and stakeholder engagement to manage reputational and political risks, and to position themselves to shape the technical rules that regulations will supply.
