ESG Implementation Operating System

1

Phase 1 — Executive Commitment

Establish the mandate, authority, and initial resource allocation for the ESG programme.

Objectives

Obtain formal board approval of the ESG programme mandate.
Designate the executive sponsor with named accountability for ESG outcomes.
Allocate a defined budget for Year 1 ESG activities, approved by the CFO.
Communicate the ESG commitment internally to all staff within 30 days of board approval.

Who Should Lead This Phase

CEO (accountable for obtaining board mandate)
CFO (accountable for budget allocation)
Board Chair (accountable for board resolution)
Company Secretary (accountable for documentation)

Detailed Activities — Step by Step

1
Brief the CEO and CFO on the regulatory, investor, and competitive drivers for ESG, using the Executive Briefing Pack from Part 13 of this toolkit. This briefing should be no longer than 20 minutes and should lead with the three most material regulatory or investor-facing obligations relevant to the organisation's sector and geography.
2
Prepare a board paper recommending approval of the ESG programme mandate. The paper should cover: the strategic rationale, the proposed governance structure, the Year 1 budget requirement, and the proposed executive sponsor. Use the Board Presentation Pack from Part 13 as the base template.
3
Present the board paper at the next scheduled board meeting. The motion for approval should be a board resolution, recorded in the minutes, designating the executive sponsor and approving the Year 1 budget. A general indication of support without a formal resolution is insufficient for this phase.
4
The CEO issues an all-staff communication within 10 business days of the board resolution, stating the organisation's ESG commitment, naming the executive sponsor, and indicating when staff will receive further information about their role in the programme.
5
The executive sponsor designates the ESG manager or coordinator within 20 business days of the board resolution, confirms the reporting line, and allocates the Year 1 budget in the financial system.
6
The ESG manager prepares a Phase 1 Completion Report summarising the board resolution, the executive sponsor mandate, the staff communication, the Year 1 budget, and the proposed timetable for Phases 2 through 9. This report constitutes the entry point for Phase 2.

RACI Matrix — Phase 1

Activity	Board	CEO	CFO	ESG Mgr
Approve ESG mandate	R	A	C	I
Allocate Year 1 budget	A	C	R	I
Designate executive sponsor	I	RA	I	I
Issue staff communication	I	RA	I	C
Phase 1 Completion Report	I	A	I	R

Quality Control Procedures

The board resolution must name the executive sponsor and state the Year 1 budget figure. A resolution without these specifics requires supplementary board approval.
The all-staff communication must be reviewed by legal or HR before distribution to ensure it does not create contractual obligations or employment law implications in any operating jurisdiction.
The Phase 1 Completion Report must be signed by the executive sponsor before Phase 2 begins. Phase 2 activity conducted without an executive sponsor signature carries the risk of being overridden or deprioritised if leadership changes.

2

Phase 2 — Governance Establishment

Build the governance architecture that will carry the ESG programme through every subsequent phase.

Objectives

Establish the board-level governance structure for ESG oversight.
Establish the management-level ESG governance structure.
Adopt Terms of Reference and charters for each governance body.
Clarify reporting lines, escalation protocols, and decision rights across the governance hierarchy.
Conduct the first meeting of each governance body within 60 days of this phase commencing.

Governance Structures to Establish

Board Sustainability Committee (or confirmed mandate for Risk or Audit Committee where a separate sustainability committee is not yet warranted)
Executive ESG Steering Committee, chaired by the executive sponsor
ESG Working Group at management level, with cross-functional representation
ESG Sub-Working Groups as needed by function (for example, procurement ESG, HR ESG, operations ESG)

Detailed Activities — Step by Step

1
Draft the Terms of Reference for the Board Sustainability Committee using the template in Part 3 of this toolkit. The ToR must specify: the committee's mandate and scope, its composition and quorum requirements, its meeting frequency (minimum quarterly), its reporting obligation to the full board, and its relationship to the Risk Committee and Audit Committee.
2
Identify the board members who will serve on the Sustainability Committee. At least one member should hold either a formal qualification in sustainability, climate risk, or ESG, or a professional background that has included direct sustainability responsibility. This requirement should be noted in the ToR and disclosed in the Annual Report.
3
Draft the charter for the Executive ESG Steering Committee. The charter must cover: composition (executive sponsor as chair, relevant C-suite members, ESG manager as secretary), meeting frequency (minimum quarterly), decision rights (which ESG decisions require Steering Committee approval versus delegation to the ESG manager), and reporting obligation to the Board Sustainability Committee.
4
Establish the ESG Working Group. Invite representatives from at minimum: finance, legal and compliance, operations, HR, procurement, and risk. The ESG manager chairs the Working Group. Establish a standing agenda structure covering data review, risk updates, action plan progress, and upcoming regulatory or reporting deadlines.
5
Develop the escalation protocol defining: which ESG matters require escalation from the Working Group to the Steering Committee, which require escalation from the Steering Committee to the Board Sustainability Committee, and which require immediate escalation to the full board. Base the thresholds on financial materiality (for example, ESG risks with a potential financial impact above 1% of revenue) and reputational materiality (matters likely to attract media attention or regulatory enquiry).
6
Convene the inaugural meeting of each governance body. Record minutes from each inaugural meeting. The first minutes should capture: the adoption of the ToR or charter, the confirmation of membership, the agreed meeting schedule for the next 12 months, and the first substantive agenda item (typically the Phase 3 Materiality Assessment commission).

Required Committees and Their Reporting Lines

Governance body	Chair	Meets	Reports to	Decision rights
Board Sustainability Committee	Board member (ESG champion)	Quarterly	Full Board	ESG strategy approval; policy endorsement; assurance scope approval
Executive ESG Steering Committee	Executive sponsor (CEO or CFO)	Quarterly	Board Sustainability Committee	ESG target approval; budget allocation within board-approved envelope; major programme decisions
ESG Working Group	ESG Manager	Monthly	Executive ESG Steering Committee	Action plan updates; data quality decisions; supplier assessment approvals
Risk Committee (with ESG mandate)	Board member	Quarterly	Full Board	ESG risk register approval; climate risk disclosure approval
Audit Committee (ESG data oversight)	Board member	Quarterly	Full Board	ESG data audit findings; assurance engagement scope; data governance approval

Quality Control Procedures

All ToR and charters must be approved by the relevant governance body at their inaugural meeting, not only presented. Presented but unapproved governance documents are not operative.
The escalation protocol must be tested with at least one hypothetical scenario at the inaugural ESG Working Group meeting to confirm that participants understand the thresholds.
Minutes from all governance meetings must be stored in a secure, version-controlled location accessible to the external auditor and the assurance provider. This is a data governance requirement that applies from the first meeting.

Common Mistakes

Establishing governance structures on paper without activating them with inaugural meetings within 60 days, resulting in a governance architecture that exists in documentation but not in practice.
Composing the ESG Working Group entirely from the sustainability function, rather than as a cross-functional group, limiting the programme's reach into operational systems where ESG data is generated.
Setting escalation thresholds that are so high that virtually no matter reaches the board, leaving the board uninformed about material ESG developments between annual reports.

3

Phase 3 — Materiality Assessment

Identify and prioritise the ESG topics that matter most to the organisation's financial performance and to its impacts on the environment and society.

Objectives

Produce a double materiality assessment that satisfies ESRS, GRI, and IFRS S1 requirements simultaneously.
Identify at minimum 15 ESG topics for assessment, drawing from GRI's universal and topic-specific standards, sector-based SASB standards, and ESRS topic lists.
Engage at minimum five distinct stakeholder groups in the assessment process.
Produce a materiality matrix that is defensible to external assurance providers and investors.
Complete the assessment within 90 days of commission.

Inputs Required

Long-list of ESG topics drawn from GRI Universal Standards, applicable SASB sector standards, and ESRS topic lists
Peer benchmarking data showing which topics competitors or sector leaders disclose
Regulatory mapping for all applicable jurisdictions (from Phase 2 compliance register)
Investor and lender ESG expectations (from Phase 1 investor conversation)
Internal risk register (preliminary)
Stakeholder identification list (minimum 5 stakeholder groups)

Step-by-Step Implementation Guidance

1
Compile the long-list of ESG topics. Begin with the full list of GRI topic-specific standards relevant to the sector. Add any topics in the applicable SASB sector standard not already covered by GRI. Add any ESRS mandatory disclosure topics. Add any topics identified through the regulatory mapping that represent legal obligations not covered by the above. The long-list should contain between 20 and 40 topics.
2
Assess each long-list topic for financial materiality: the degree to which ESG risks or opportunities related to that topic affect the organisation's financial position, cash flows, or access to capital within a 0 to 5 year horizon. Score each topic from 1 (negligible financial relevance) to 5 (material financial impact evidenced by peer cases or regulatory development).
3
Assess each long-list topic for impact materiality: the degree to which the organisation's activities cause positive or negative impacts on the environment or people across the value chain. Assess by the scale of the impact (local, national, global), its severity (reversible versus irreversible), and its probability. Score each topic from 1 to 5 on each of these three dimensions; average the three scores for a single impact materiality score.
4
Conduct structured stakeholder engagement across at minimum five groups. Recommended groups are: investors and lenders, employees (via representative sample or staff survey), customers or clients, suppliers (via the top 10 by spend), and community or civil society representatives. For each group, administer a structured questionnaire asking them to rate each long-list topic by importance from their perspective. Record response rates and use the aggregated scores to inform the stakeholder importance axis of the materiality matrix.
5
Plot the double materiality matrix with impact materiality on one axis and financial materiality on the other. Topics scoring above the materiality threshold on either axis (not both) are material under ESRS and GRI definitions. Define the materiality threshold and document the rationale; the threshold should be consistent with the organisation's financial reporting materiality policy where one exists.
6
Present the draft materiality matrix to the Executive ESG Steering Committee for validation. The Steering Committee may adjust the threshold or reorder topics within a band if new information is available; all adjustments must be documented with their rationale. After Steering Committee approval, present the final matrix to the Board Sustainability Committee for endorsement.
7
Document the assessment methodology in a Materiality Assessment Report covering: the long-list source, the scoring methodology, stakeholder engagement methods and response rates, the threshold definition, and the final list of material topics. This report is an audit-facing document and should be written to the standard required for external review.

Tools Required

Materiality Matrix Builder (Part 9) Stakeholder Mapping Tool (Part 9) GRI Topic Standards SASB Sector Standard ESRS Topic List Stakeholder Questionnaire Template

Quality Control Procedures

The materiality assessment methodology must be documented before scoring begins. Post-hoc rationalisation of the methodology is a common failure point that creates assurance problems.
Stakeholder engagement response rates below 40% in any group should prompt either additional outreach or a documented note explaining why the group's low response rate does not bias the outcome.
The final material topics list should be cross-checked against the organisation's three most material peer competitors' most recent disclosures. A topic that peers disclose but the organisation has not identified as material requires a documented explanation in the assessment report.

4

Phase 4 — Baseline Assessment

Establish the current-state performance across all material ESG topics identified in Phase 3, creating the data foundation for target setting and progress measurement.

Objectives

Collect and verify baseline data for all material topics from Phase 3.
Establish the base year for all quantitative targets (to be set in Phase 6).
Identify data gaps and develop a data gap closure plan with completion dates.
Complete the baseline assessment within 120 days of the materiality assessment completion date.

Data Scope by Material Topic Category

Climate and energy: Scope 1, 2, and material Scope 3 emissions; total energy by type; renewable energy percentage
Water: total withdrawal by source; water-stressed area withdrawal; water consumption
Waste: total waste by type and disposal method; hazardous waste percentage
Social: headcount by gender and employment type; pay gap (if measurable); OHS incident rate and severity rate; training hours per employee
Governance: board composition by gender and independence; ethics incident count; anti-corruption training coverage percentage
Supply chain: supplier coverage in ESG assessment; number of suppliers assessed; high-risk supplier remediation rate

Step-by-Step Implementation Guidance

1
For each material topic, identify the data owner: the internal function responsible for the source data. Climate and energy data sits with operations or facilities. Waste data sits with operations or the EHS function. Social data sits with HR. Governance data sits with the Company Secretary. Supply chain data sits with procurement. Assign a data owner from each function to the ESG Working Group for the duration of this phase.
2
Deploy the ESG Data Collection Template (from Part 9) to each data owner. The template specifies the metric, the unit of measurement, the calculation methodology, the required data source, and the reporting period. Each data owner completes their section for the 12-month base year period. The ESG manager reviews each submission against the calculation methodology before accepting it.
3
Calculate the GHG emissions inventory for the base year. Scope 1: direct emissions from owned or controlled sources, calculated using the GHG Protocol Corporate Standard with emissions factors from the IPCC AR6 report or the IEA national grid factor as applicable. Scope 2: indirect emissions from purchased electricity, calculated using both market-based and location-based methods, both reported. Scope 3: material categories identified in Phase 3, estimated using the GHG Protocol Scope 3 Standard spend-based or average-data method where primary supplier data is unavailable.
4
Document each data gap: a topic or metric for which base year data is unavailable or below acceptable quality. For each gap, record the reason for absence, the data collection system that would close it, the estimated time to close it, and the person responsible. Gaps that cannot be closed within 6 months should be disclosed as data limitations in the first ESG report, with an estimate or industry average substituted and clearly labelled.
5
Compile the Baseline Assessment Report. This report presents the base year performance across all material topics, the data gap closure plan, and a preliminary comparison against at least one external benchmark per topic category (for example, the IEA global emissions intensity average for the sector for climate topics, and the ILO sector average for OHS topics). The report is the primary input into Phase 6 (Target Setting).

Common Mistakes

Selecting a base year for which complete data is unavailable, requiring estimates to be used for the base year, which then undermines the credibility of future progress claims.
Calculating Scope 1 and 2 emissions without establishing the boundary of the calculation (operational control versus equity share), resulting in figures that cannot be compared with peer organisations using a different boundary approach.
Treating the baseline data as confidential rather than as the starting point for transparent progress reporting, which limits the baseline's value as a motivation and accountability tool internally.

Quality Control Procedures

Every metric in the Baseline Assessment Report must identify its data source, the calculation method applied, and the person who provided and the person who reviewed the data.
The GHG emissions inventory should be reviewed by an independent GHG accountant or the organisation's internal audit function before it is used as the base year for target setting. An unreviewed base year is a common cause of target-setting errors that create assurance complications in later years.
The Baseline Assessment Report must be approved by the Executive ESG Steering Committee before Phase 6 begins. Target setting against an unapproved baseline creates the risk of executive disagreement with the base year that requires Phase 4 to be partially repeated.

5

Phase 5 — ESG Risk Assessment

Assess ESG risks using the same methodology as the enterprise risk framework, integrating climate, social, and governance risks into the board-level risk register.

Objectives

Assess all material ESG topics from Phase 3 for their associated risks and opportunities.
Complete a TCFD-aligned climate risk assessment covering physical and transition risks across at minimum two scenarios.
Conduct a high-level human rights due diligence assessment covering operations and the top 20 suppliers.
Integrate material ESG risks into the enterprise risk register within 90 days of this phase commencing.

Risk Categories to Assess

Physical climate risks: acute (extreme weather events) and chronic (temperature increase, sea level rise, water stress)
Transition climate risks: policy and legal, technology, market, and reputational
Nature and biodiversity risks: habitat loss, ecosystem service dependency, regulatory risk from nature-related legislation
Social risks: labour rights in operations and supply chain, community relations, health and safety
Governance risks: corruption, ethics breaches, tax transparency, data governance failures
ESG opportunities: new markets from green products, preferential financing, talent advantage, regulatory compliance benefit

Climate Scenario Analysis — Minimum Requirements

Scenario	Warming pathway	Risk type	Time horizons	Sources
Net-zero or rapid transition	1.5°C (IEA NZE or equivalent)	Transition risks dominant	Short (to 2030), medium (to 2040)	IEA World Energy Outlook, NGFS scenarios
Delayed transition	2°C to 3°C (NGFS Hot House World)	Physical risks dominant in long term	Long (to 2050 and beyond)	IPCC AR6, NGFS scenarios

Step-by-Step Guidance

1
Map each material ESG topic to its associated risks and opportunities using the ESG Risk Assessment template in Part 6. For each risk, assign a likelihood score (1 to 5) and an impact score (1 to 5) using the same scale as the enterprise risk framework. Calculate a risk rating (likelihood multiplied by impact) and classify as Low (1 to 6), Medium (7 to 14), or High (15 to 25).
2
Conduct the climate scenario analysis using at minimum the two scenarios above. For each scenario, identify the specific physical or transition risks that are material for the organisation's sector and geography, estimate the potential financial impact of each risk within the defined time horizons, and identify existing controls or planned mitigations.
3
Conduct the human rights due diligence assessment using the HRDD template in Part 6. Map the organisation's activities and supply chain against the 11 human rights categories most commonly salient in the sector, sourced from the UN Guiding Principles Reporting Framework sector guidance. Assess likelihood of adverse impact on each category and the severity of potential harm.
4
Integrate all ESG risks rated Medium or above into the enterprise risk register, in the standard format used for other enterprise risks. Present the integrated risk register to the Risk Committee at its next scheduled meeting, with a cover note explaining the ESG risk assessment methodology and the basis for each ESG risk rating.

Quality Control Procedures

The ESG risk assessment must use the same scoring scale as the enterprise risk framework. A separate ESG risk scoring system creates a comparison problem when ESG risks are presented alongside financial and operational risks to the board.
The climate scenario analysis must specify the source of each scenario assumption. Unattributed scenario assumptions cannot be validated by external assurance providers.
The human rights due diligence assessment must be reviewed by the legal function before finalisation, as findings may have implications for the organisation's statutory reporting obligations under applicable modern slavery or human rights due diligence legislation.

6

Phase 6 — Target Setting

Set specific, time-bound, and externally verifiable ESG targets across all material topics, grounded in the base year established in Phase 4.

Target Setting Criteria

Every target must state the base year, the target year, the base year value, and the target value.
Where an external standard applies (for example, SBTi for emissions, CDP for water security), the target must be aligned with that standard's requirements.
Targets must be reviewed and approved by the Executive ESG Steering Committee before being embedded in the operating plan.
Targets must be achievable without additional capital investment beyond the approved Year 1 budget, unless the target explicitly names the capital investment required and its approval status.
At least three targets must be included in executive variable compensation from the first full year following their approval.

Target Types

Absolute reduction targets: state the absolute quantity to be reduced (for example, a 42% reduction in Scope 1 and 2 emissions by 2030 against a 2022 base year, consistent with a 1.5°C aligned trajectory under the SBTi Corporate Net-Zero Standard)
Intensity reduction targets: state the reduction per unit of output (for example, a 35% reduction in water withdrawal per tonne of product by 2028 against a 2023 base year)
Coverage targets: state the percentage of a population to reach (for example, 100% of the top 50 suppliers by spend assessed against the Supplier Code of Conduct by end of 2026)
Representation targets: state the percentage representation to achieve (for example, 40% of senior management roles filled by women by end of 2027, against a 2023 base of 28%)

Minimum Target Set — All Organisations

Topic	Target type	External alignment	Disclosure requirement
GHG emissions (Scope 1 and 2)	Absolute reduction, % by target year vs base year	SBTi 1.5°C pathway required at Level 4+	TCFD; IFRS S2; GRI 305
GHG emissions (Scope 3 material categories)	Absolute or intensity reduction by category	SBTi FLAG or SBTi Corporate (sector-specific)	TCFD; IFRS S2; GRI 305
Energy intensity	Intensity reduction per unit revenue or output	ISO 50001 aligns with this target type	GRI 302; ESRS E1
Water withdrawal	Absolute or intensity reduction; water-stressed area target separate	CDP Water Security aligned	GRI 303; ESRS E3
Waste diversion from landfill	Coverage target, % of total waste diverted	Circular economy principle	GRI 306; ESRS E5
Gender representation in senior roles	Representation target, % women in senior management by year	UN Women Empowerment Principles	GRI 405; ESRS S1
OHS performance	Reduction target for Total Recordable Incident Rate	ISO 45001 aligned	GRI 403; ESRS S1
Supplier ESG coverage	Coverage target, % of expenditure with assessed suppliers	GRI 308 and 414 aligned	GRI 308; ESRS G1

Common Target-Setting Errors

Setting targets without base year values, making progress measurement impossible and exposing the organisation to greenwashing risk if progress claims are made without a verifiable starting point.
Setting targets for metrics where data quality is poor, creating a situation where the target cannot be measured against the base year with confidence. Data gaps identified in Phase 4 should be closed before targets are set on the affected metrics.
Setting targets that are achievable without any change in behaviour or investment, which undermine the credibility of the programme with external stakeholders who can identify stretch-free targets from benchmark data.
Setting targets without embedding them in the operating plan or budget cycle, resulting in targets that are aspirational statements rather than managed commitments.

7

Phase 7 — Strategy Development

Build the ESG strategy that translates materiality findings, risk assessments, and targets into a coherent long-term direction embedded in the corporate strategy.

Objectives

Produce a written ESG Strategy document approved by the board.
Demonstrate a clear link between the ESG strategy and the corporate strategy.
Identify at least three ESG-driven business opportunities and one ESG-driven capital market benefit.
Define the ESG value creation narrative for use with investors and lenders.

ESG Strategy Canvas Structure (Part 9)

Context: material ESG topics, regulatory drivers, stakeholder expectations, peer positioning
Ambition: the long-term ESG vision, aligned with the corporate strategy purpose statement
Strategic priorities: the three to five ESG priorities that will receive the majority of management attention and investment in the planning period
Value creation: the specific commercial, financial, and social outcomes the strategy is designed to deliver
Governance: how the strategy will be governed, measured, and reported
Resource requirements: people, systems, and capital required to execute the strategy

Strategy Development Process — Step by Step

1
Convene a strategy workshop with the Executive ESG Steering Committee. Present the outputs from Phases 3 (materiality), 4 (baseline), 5 (risk assessment), and 6 (targets). Use the ESG Strategy Canvas as the workshop framework. The workshop should run for a minimum of four hours and should produce a draft version of each section of the Canvas.
2
Validate the draft strategy against the corporate strategy document. Every ESG strategic priority should be traceable to at least one corporate strategic objective. If an ESG priority does not connect to the corporate strategy, it is either misclassified as a strategic priority (and should be reclassified as an operational activity), or the corporate strategy requires updating to reflect the organisation's ESG ambition.
3
Develop the ESG value creation narrative. This narrative states specifically: which ESG performance improvements will reduce the organisation's cost of capital or improve access to finance, which will generate new revenue or protect existing revenue, and which will reduce operating costs. The narrative must be quantified where possible. A narrative stating only that ESG creates value, without specifying which value and by which mechanism, does not pass the Defensibility Test applied in the QA/QC protocol of this toolkit.
4
Present the ESG Strategy to the Board Sustainability Committee for review and refinement. Board members should be given at least 10 business days to review the document before the meeting. The Committee endorses the strategy and recommends it to the full board for approval.
5
Obtain full board approval of the ESG Strategy. Record the approval in board minutes. This approval authorises the progression to Phase 8 (Action Planning) and Phase 9 (Execution).

8

Phase 8 — Action Planning

Translate the ESG strategy and targets into specific, budgeted, and owned action plans at the business unit and functional level.

Action Plan Components

For each ESG target approved in Phase 6, an action plan must specify the actions required to achieve the target, the business unit or function responsible, the timeline and interim milestones, the budget allocated, and the owner (named individual).
Actions must be at a level of specificity that can be tracked in a project management system, not at a level of generality that would require further decomposition before work begins.
Each action plan must be reviewed and approved by the head of the responsible business unit before it is submitted to the ESG Working Group.

Action Plan Template Structure

Target reference and target value
Gap between current performance and target
Actions required (specific, numbered)
Owner of each action (named person)
Start date and completion date for each action
Budget required for each action
Enabling conditions (approvals, data access, systems changes) and who is responsible for each
Interim milestones at 30, 60, 90 days for Year 1 actions
Risk to action completion and mitigation

Quality Control Procedures

Action plans that do not name an individual owner for each action, but instead name a team or department, are rejected at the Working Group review stage and returned for revision. Accountability at team level rather than individual level is the most consistent predictor of action plan underperformance.
Every action that requires budget must reference the specific cost centre and the approval status of the required budget. Planned actions without confirmed budget are recorded as contingent actions and are not tracked in the primary action plan.
The ESG manager consolidates all business unit and functional action plans into the ESG Project Management Template (Part 13) within 30 days of the last action plan being received. The consolidated plan is the ESG Programme's primary management tool and is reviewed at every ESG Working Group meeting.

Common Mistakes

Action plans are approved but not integrated into the business unit's operational plans, leaving ESG actions as an addition to existing workloads rather than a managed priority.
Interim milestones are set only at the annual level, meaning that deviations from plan are identified 12 months after they occur rather than within 30 to 60 days of occurrence.
The ESG action planning process is run separately from the annual operating plan cycle, creating a disconnect that makes it difficult to secure resource commitment from business unit heads who manage against their operational plan, not the ESG plan.

9

Phase 9 — Execution

Deliver the action plans while managing dependencies, resolving blockers, and maintaining governance oversight across the full programme.

Operating Rhythm During Execution

Meeting	Frequency	Participants	Agenda standing items	Output
ESG Working Group	Monthly	ESG manager + functional reps	Action plan RAG status; data quality update; blockers; upcoming deadlines	Updated action plan; escalation memo if required
Executive ESG Steering Committee	Quarterly	Executive sponsor + C-suite + ESG manager	Programme progress vs targets; budget vs actuals; risk register update; escalated issues	Steering Committee minutes; decisions on resource or priority changes
Board Sustainability Committee	Quarterly	Board members + executive sponsor + ESG manager	Target progress; risk update; external environment scan; emerging regulatory developments	Board minutes; board decisions on strategy adjustments
Investor or lender ESG update	At least annually (biannually for sustainability-linked instrument holders)	CFO + ESG manager + investor relations	Annual performance against ESG targets; narrative on programme progress	Investor update pack; lender compliance certificate where required

Execution Management Tools

ESG Programme Dashboard (Part 13): a single-page view of all targets, their current RAG status, the trend (improving, stable, declining), and the action owner
ESG Action Plan Tracker (Part 9): the full action plan in project management format, updated monthly by the ESG manager and reviewed at every Working Group meeting
Data Quality Log: a rolling record of data issues identified, their resolution status, and the person responsible for resolution
Stakeholder Engagement Log: a record of all material stakeholder interactions, issues raised, and the organisation's response

Quality Control Procedures

Any action rated Red (behind schedule or at risk of not achieving the target) for two consecutive months must be escalated to the Executive ESG Steering Committee with a recovery plan, not only noted in the Working Group minutes.
Budget expenditure against the ESG programme budget is reviewed by the CFO's office at each quarterly Steering Committee meeting, in the same format as other programme budget reviews.
The ESG manager submits a monthly programme status report to the executive sponsor, no longer than two pages, structured as: status summary, key accomplishments in the period, actions behind schedule and recovery plans, resource or budget variances, and priorities for the next 30 days.

10

Phase 10 — Monitoring

Collect, validate, and analyse ESG performance data on a regular cycle to enable timely management decisions and accurate reporting.

Monitoring Frequency by Data Category

Energy and emissions data: monthly collection, quarterly review
Water and waste data: monthly collection, quarterly review
OHS incident data: weekly collection, monthly review
Social and DEI data: quarterly collection, annual review and public disclosure
Supplier ESG assessment data: updated on contract renewal cycle or annual questionnaire
Governance and ethics incident data: ongoing, reviewed monthly by the compliance function

Data Validation Procedures

At the point of submission, every data provider must confirm the data source and that the calculation method matches the method specified in the Data Collection Template.
The ESG manager reviews each submission within 10 business days of the collection deadline, applying the validation checks defined in the Data Governance Policy.
Where a data point deviates by more than 15% from the equivalent period in the prior year, the data provider is required to provide a written explanation before the data is accepted into the monitoring dataset.
All validated data is uploaded to the ESG data management system within 30 days of the collection deadline. Late or unvalidated data is flagged in the monthly programme status report.

ESG Dashboard Template — Structure

Section	Content	Update frequency	Audience
Target performance summary	Each target, current value, base year value, target value, RAG status, trend	Quarterly	Executive Steering Committee; board
Climate performance	Scope 1, 2, and 3 emissions vs base year and target trajectory; energy intensity	Quarterly	Board Sustainability Committee; investors
Social performance	TRIR; gender representation; training hours; community investment	Quarterly	ESG Working Group; board
Governance performance	Ethics incidents; policy compliance rate; board composition	Quarterly	Audit Committee; board
Supply chain performance	Supplier coverage rate; high-risk supplier remediation rate	Quarterly	Procurement Working Group; board
Financial integration	ESG budget vs actual; green finance utilisation; cost of capital impact	Quarterly	CFO; board

11

Phase 11 — Reporting

Produce accurate, comparable, and assurance-ready ESG disclosures across all applicable frameworks and audiences.

Report Types and Publication Schedule

Annual Sustainability Report or ESG Report: published within 5 months of the financial year-end
Integrated Report (Level 4+): published within 4 months of the financial year-end, incorporating financial and non-financial performance
TCFD Report or TCFD-aligned section of Annual Report: published annually, covering all four TCFD pillars
CDP Climate Change response: submitted annually in accordance with CDP's submission cycle (typically July)
Lender or investor ESG update: submitted to sustainability-linked instrument holders as per instrument terms, typically annually or semi-annually

Report Production Process

Start report drafting 4 months before the publication date, not 6 to 8 weeks before. Late starts are the single most common cause of ESG report quality failures.
Assign a named author and a named reviewer for each section. No section is accepted into the final report without both an authoring sign-off and a peer reviewer sign-off.
Complete the disclosure index before drafting narrative content. The disclosure index maps each required disclosure to the relevant section of the report. Drafting without a completed index produces reports with coverage gaps that are only discovered at the quality review stage.
Submit the draft report to the ESG Working Group for factual accuracy review before submitting to the Executive ESG Steering Committee. The Steering Committee reviews for completeness and strategic alignment. The Board Sustainability Committee approves the final version.
Submit the approved draft to the assurance provider at least 6 weeks before the planned publication date.

12

Phase 12 — Assurance

Obtain independent verification of material ESG data and disclosures to the standard appropriate for the organisation's maturity level and stakeholder expectations.

Assurance Levels and When to Use Each

Limited assurance (Level 2 to 3): the assurer concludes that nothing has come to their attention indicating the data contains material misstatement. Applicable standard: ISAE 3000 (Revised) or AA1000AS Type 2. Typical cost for a mid-size organisation: USD 40,000 to USD 100,000.
Reasonable assurance (Level 4+): the assurer provides positive assurance that the data presents a true and fair view. Applicable standard: ISAE 3000 (Revised) to reasonable assurance level. Typical cost for a mid-size organisation: USD 80,000 to USD 250,000.
GHG verification: specific to the GHG inventory. Applicable standard: ISO 14064-3. Can be obtained separately from general ESG data assurance. Typical cost: USD 20,000 to USD 60,000.

Assurance Scope — What to Prioritise

Year 1 assurance should cover at minimum: total Scope 1 and 2 GHG emissions; total energy consumption; Total Recordable Incident Rate; and the three ESG targets embedded in executive compensation.
Year 2 and beyond: extend assurance coverage to all material ESG metrics in the annual report, aiming for full coverage of all quantitative disclosures within three years.
The assurance scope must be agreed with the Audit Committee before the engagement commences, not after the report is drafted. Agreeing the scope after drafting limits the assurer's ability to review the underlying data collection and calculation process.

Phase 13 — Continuous Improvement

Use the monitoring, reporting, and assurance outputs to identify priority improvements for the next annual cycle, advancing the programme's maturity and effectiveness.

Annual Improvement Cycle

Conduct the annual improvement review within 30 days of the sustainability report being published. Use the assurance findings, the materiality matrix review (updated for any change in the external environment), and the target achievement record as the primary inputs.
Identify the three actions that would most improve ESG performance in the next 12 months, based on the gap between current performance and target on each material metric.
Identify the two data quality improvements that would most improve the reliability of the next report, based on the assurance provider's findings.
Update the target set for the next annual cycle: confirm which targets are on track to be achieved, which require acceleration, and which require revision due to a material change in the external environment or the organisation's business model.
Update the materiality assessment to reflect any material regulatory, market, or stakeholder development that occurred in the prior 12 months. A full re-assessment is required at least every three years; an annual update review is required every year.

Maturity Advancement Indicators

The programme is advancing if: the number of metrics with third-party assurance increases year on year; the gap between current performance and target narrows year on year for at least 70% of metrics; and the ESG governance bodies have had no meeting cancelled in the prior 12 months.
The programme is stagnating if: two or more targets are missed in the same year without a documented explanation; the materiality assessment has not been updated in 24 months; or the assurance scope has not expanded in two consecutive years.
A maturity advancement review should be conducted annually using the ESG Maturity Assessment in Part 6 of this toolkit, with results presented to the Board Sustainability Committee and used to set the improvement agenda for the next cycle.
