The problem

What's at stake

ESG and sustainability reporting increasingly carry regulatory weight, but the underlying data is fragmented, inconsistent, and hard to audit - especially Scope 3 emissions and supply-chain data.

Business impact

Why it matters

Governed ESG data foundations make disclosures credible and auditable, reduce the manual effort behind each report, and prepare organizations for tightening regulation.

The deeper problem is that sustainability reporting has moved from voluntary narrative to regulated, assured disclosure faster than most organisations' data has kept up. Figures are still assembled by hand from scattered operational, energy and supply-chain sources, with little lineage and inconsistent quality, so each reporting cycle is a manual scramble that produces numbers few could defend under audit.

That fragility is becoming a real risk. As external assurance becomes the norm and requirements multiply, disclosure that cannot be traced to governed data will not withstand scrutiny, and the manual effort behind each report grows rather than shrinks. Treating ESG as a reporting exercise on shaky data, rather than a data problem to be solved once, is where the exposure lies.

Context

Why this matters now

Sustainability disclosure has moved from voluntary narrative to regulated, assured reporting. Frameworks are tightening, external assurance is becoming the norm, and a disclosure that cannot be traced to governed data is now a real risk rather than a presentational weakness.

Yet most ESG reporting is still assembled manually from scattered sources, which is slow, costly and fragile. The organisations that get ahead treat ESG as a data-engineering problem first, building a governed foundation that makes every disclosure credible and every new requirement manageable, which is what this practice delivers.

Our point of view

How we see this

Our point of view on ESG is that it is a data-engineering problem before it is a disclosure problem. Credible, assurance-ready reporting depends on governed, traceable data, and reporting built on ungoverned spreadsheets will not survive external assurance or the next tightening of regulation. Treating ESG as a reporting exercise on top of shaky data is a common and increasingly risky mistake.

We also argue for sourcing ESG data from the operations the business already runs rather than building a parallel ESG data estate. Data drawn from the real operational systems is both more credible to an assurer and less costly to maintain, and it avoids the trap of a separate ESG dataset that drifts away from operational reality.

Finally, we treat regulatory change as a design assumption rather than a recurring shock. Requirements are tightening and multiplying, so the foundation should be built so that each new rule becomes a data-mapping exercise rather than a fresh programme. That is what turns ESG reporting from a perpetual scramble into a durable, governed capability.

Our approach

How we work

We treat ESG as a data engineering and governance problem: trusted sources, clear lineage, and quality controls, so sustainability numbers are as defensible as financial ones.

In practice we start by mapping the disclosures and frameworks you must satisfy to the underlying data they require, then build a governed foundation drawn from the operations you already run, automate the collection that repeats each cycle, and add the lineage and quality that make disclosures assurance-ready.

The throughline is that credible ESG reporting is built on governed data, not assembled on top of spreadsheets. Get the foundation right, and each new requirement becomes a data-mapping exercise rather than a fresh programme, which is what makes the capability durable as regulation tightens.

Our framework

Gravitas ESG Data Framework

Credible sustainability reporting rests on governed data, yet most ESG disclosure is still assembled by hand from scattered sources. We use a five-stage index to show sponsors how far ESG data has moved from manual spreadsheets to an auditable, governed foundation that stands up to tightening regulation and external assurance.

1ManualSpreadsheets, ad hocMost firms start here2ConsolidatedCentral ESG data3GovernedLineage and quality4AuditableAssurance-ready5IntegratedESG in the business

Most organisations sit at Manual or Consolidated: data is gathered, but it is not yet governed, traceable or ready for external assurance. Each stage up reduces manual effort and strengthens the credibility of every disclosure.

Level 1 of 5

Manual

Where the business is ESG disclosures are assembled by hand from scattered sources. The process is slow, costly and error-prone. For a sponsor, the practical signal is how much manual effort and disagreement surrounds the work at this point, and how much of it depends on a few individuals rather than a repeatable capability.

What it costs The cost is not only effort but credibility: manual, untraceable data will not withstand external assurance or tightening regulation. Left unaddressed, this is the kind of cost that does not appear as a line item but shows up as slower decisions, avoidable rework and risk that is only priced once it materialises.

What we do We map the disclosures and frameworks you must satisfy to the data they require, so effort targets what actually matters. We do this in a contained, evidenced way, with an agreed output, so the move to the next stage is something the business can see and fund with confidence rather than take on trust.

What good looks like In practice, a sponsor can recognise this stage by the amount of manual effort and disagreement around the numbers; the goal of the first move is to make that pain visible and bounded rather than pervasive.

Level 2 of 5

Consolidated

Where the business is ESG data is gathered centrally, but it is not yet governed, traceable or assurance-ready. For a sponsor, the practical signal is how much manual effort and disagreement surrounds the work at this point, and how much of it depends on a few individuals rather than a repeatable capability.

What it costs Central-but-ungoverned data still cannot be defended to an auditor, and each report remains a manual burden. Left unaddressed, this is the kind of cost that does not appear as a line item but shows up as slower decisions, avoidable rework and risk that is only priced once it materialises.

What we do We build a governed ESG data foundation drawn from operational, energy and supply-chain sources, with the first quality controls. We do this in a contained, evidenced way, with an agreed output, so the move to the next stage is something the business can see and fund with confidence rather than take on trust.

What good looks like The tell-tale sign of this stage is that things look better on the surface while the underlying capability is still thin; our work here is about turning apparent order into real, evidenced control.

Level 3 of 5

Governed

Where the business is ESG data has lineage and quality. Disclosures are traceable to their sources and the manual effort behind each report falls. For a sponsor, the practical signal is how much manual effort and disagreement surrounds the work at this point, and how much of it depends on a few individuals rather than a repeatable capability.

What it costs The gap now is external assurance: governed data must be shaped so it can withstand formal audit. Left unaddressed, this is the kind of cost that does not appear as a line item but shows up as slower decisions, avoidable rework and risk that is only priced once it materialises.

What we do We add pipelines and automation that replace manual collection and prepare the foundation for assurance. We do this in a contained, evidenced way, with an agreed output, so the move to the next stage is something the business can see and fund with confidence rather than take on trust.

What good looks like At this stage the organisation has earned genuine trust in its foundation, and the conversation shifts from fixing problems to unlocking speed, efficiency and readiness for what comes next.

Looks likecurrent realityCostwhat it drags onWe dohow we move you up
Level 4 of 5

Auditable

Where the business is Disclosures are assurance-ready. Lineage and quality let each one withstand external audit and scrutiny. For a sponsor, the practical signal is how much manual effort and disagreement surrounds the work at this point, and how much of it depends on a few individuals rather than a repeatable capability.

What it costs Firms that stop here are credible today but may still scramble each time regulation tightens. Left unaddressed, this is the kind of cost that does not appear as a line item but shows up as slower decisions, avoidable rework and risk that is only priced once it materialises.

What we do We prepare the foundation for changing requirements so new rules become a data-mapping exercise, not a fresh programme. We do this in a contained, evidenced way, with an agreed output, so the move to the next stage is something the business can see and fund with confidence rather than take on trust.

What good looks like Reaching this stage changes how the business feels day to day: decisions rest on current information, surprises are rarer, and effort moves from keeping the lights on to creating advantage.

Level 5 of 5

Integrated

Where the business is ESG data is part of the business, sourced from the same operations the organisation already runs, and reporting is repeatable and credible. For a sponsor, the practical signal is how much manual effort and disagreement surrounds the work at this point, and how much of it depends on a few individuals rather than a repeatable capability.

What it costs This is where ESG stops being a parallel, costly exercise and becomes a governed, efficient, credible capability. Left unaddressed, this is the kind of cost that does not appear as a line item but shows up as slower decisions, avoidable rework and risk that is only priced once it materialises.

What we do We integrate ESG data with the wider data foundation so sustainability reporting draws on the same trusted source as the rest of the business. We do this in a contained, evidenced way, with an agreed output, so the move to the next stage is something the business can see and fund with confidence rather than take on trust.

What good looks like This final stage is less a destination than a standing capability; the work here is to keep it current as conditions, regulation and the estate evolve, so the gains hold rather than decay.

Principles

The principles behind our work

We treat ESG as a data-engineering problem first, building a governed, traceable foundation, because credible disclosure depends on data that can withstand assurance.

We automate collection to replace manual gathering, cutting both effort and error, and we build lineage and quality so every disclosure can survive external audit.

We source ESG data from the operations the business already runs rather than a parallel estate, which is both more credible and less costly, and we prepare for regulation that keeps tightening.

Capabilities

Five capability themes for the sponsor

We group ESG data work into five themes leadership can weigh, each tied to credible, efficient reporting rather than a technical task list.

ReportingscopeESGdata foundationPipelinesLineageRegulatoryreadinessCapabilities

Reporting scope and framework

Mapping the disclosures and frameworks you must satisfy to the data they require, so effort targets what actually matters. Done well, this means disclosures that withstand assurance, produced with far less manual effort and ready for tightening regulation.

ESG data foundation

A governed, central foundation for ESG data drawn from operational, energy, supply-chain and other sources. Done well, this means disclosures that withstand assurance, produced with far less manual effort and ready for tightening regulation.

Pipelines and automation

Pipelines that replace manual collection, reducing the effort behind each report and the errors that come with it. Done well, this means disclosures that withstand assurance, produced with far less manual effort and ready for tightening regulation.

Lineage, quality and assurance

Lineage and quality so disclosures are traceable and can withstand external assurance and audit. Done well, this means disclosures that withstand assurance, produced with far less manual effort and ready for tightening regulation.

Regulatory readiness

Preparing the foundation for tightening regulation, so new requirements are a data-mapping exercise, not a fresh scramble. Done well, this means disclosures that withstand assurance, produced with far less manual effort and ready for tightening regulation.

Reporting scope and framework is where we focus effort. We map the disclosures and frameworks you must satisfy to the underlying data they require, so work targets what actually matters rather than boiling the ocean. This turns a daunting compliance landscape into a concrete data problem.

We map obligations to data first, so the programme targets the disclosures and metrics that actually matter rather than attempting everything at once.

ESG data foundation is the substance of credible reporting. We build a governed, central foundation drawn from operational, energy and supply-chain sources, so disclosures rest on real, owned data rather than scattered spreadsheets. This is the layer that makes everything above it defensible.

We build the foundation from the operations the business already runs, which is both more credible to an assurer and less costly than a parallel ESG data estate.

Pipelines and automation replace manual effort. We build pipelines that supersede hand collection, cutting both the effort behind each report and the errors that come with it. This is where the recurring cost of ESG reporting falls sharply.

We automate the collection that is repeated every reporting cycle, so the recurring manual burden and its errors fall rather than persisting indefinitely.

Lineage, quality and assurance make disclosures survive scrutiny. We add lineage and quality so each disclosure is traceable and can withstand external assurance and audit, which is fast becoming the norm. This is the difference between a number you publish and one you can defend.

We build lineage and quality so each figure can be traced and defended, which is exactly what external assurance now expects to see.

Regulatory readiness prepares you for rules that keep tightening. We shape the foundation so new requirements become a data-mapping exercise rather than a fresh programme, so you stay ahead of regulation instead of scrambling after it. This is what makes the investment durable.

We shape the foundation for change, so a new requirement becomes a mapping exercise rather than a fresh scramble, which is what protects the investment over time.

See the detailed capabilities within these themes
  • ESG Strategy. We translate ambition and regulatory obligation into a prioritized, costed ESG roadmap - defining scope, sequencing, target operating model and the data foundation required, so investment is defensible to the board and traceable to outcomes.
  • Materiality Assessment. We run structured materiality assessments to identify the ESG topics that matter to your business and stakeholders, focusing reporting and data effort where it is decision-useful rather than spreading it thin.
  • Double Materiality. We conduct CSRD/ESRS-aligned double materiality - assessing both impact materiality (your effect on people and planet) and financial materiality (sustainability's effect on you) - with a documented, auditable process regulators and assurers accept.
  • ESG Operating Model. We design the operating model that makes ESG sustainable: roles across sustainability, finance, data and business units; decision rights; controls; and the cadence that keeps reporting running between cycles rather than as an annual fire drill.
  • ESG Governance. We establish governance - board committee reporting, policies, controls, ownership and decision rights over ESG data and disclosure - so ESG is governed with the rigor of financial reporting.
  • Carbon Accounting. We implement GHG Protocol-aligned carbon accounting with defensible methodologies, emission factors and calculation logic - moving you off fragile spreadsheets onto a controlled, repeatable, auditable process.
  • Scope 1, 2 & 3. We build the data flows and calculations for direct (Scope 1), energy (Scope 2) and value-chain (Scope 3) emissions, with particular focus on the Scope 3 supplier-data and estimation challenge that defeats most programs.
  • GHG Inventory. We stand up a complete, documented greenhouse-gas inventory with clear boundaries, methodologies and evidence - the auditable baseline every target and disclosure depends on.
  • Climate Risk. We assess physical and transition climate risk aligned to TCFD/ISSB, integrating it with enterprise risk management so climate becomes a quantified input to strategy and financial planning.
  • Scenario Analysis. We implement climate scenario analysis - across relevant warming and transition pathways - to quantify resilience and exposure, producing the forward-looking analysis regulators and investors expect.
  • ESG Data Architecture. We design the enterprise ESG data architecture - source integration, lakehouse, governance, semantic layer and BI/AI - so sustainability data is engineered once and reused across every framework and disclosure.
  • ESG Data Engineering. We build the pipelines that ingest, transform and reconcile ESG data from ERP, HR, procurement, energy and supplier systems - replacing manual collection with automated, tested, monitored data flows.
  • ESG Reporting. We deliver assurance-ready reporting that maps a single governed data set to multiple frameworks, eliminating the duplicated, inconsistent effort of reporting each standard separately.
  • ISSB (IFRS S1 & S2). We implement ISSB readiness - governance, metrics, climate disclosure and data - so you meet the global baseline investors increasingly expect.
  • CSRD & ESRS. We build CSRD/ESRS reporting capability - double materiality, the full datapoint set, digital tagging and assurance readiness - turning a daunting mandate into a controlled data program.
  • GRI & SASB. We map and implement GRI and SASB/ISSB industry metrics from the same governed data foundation, serving multi-framework stakeholders without parallel processes.
  • TCFD & TNFD. We implement climate (TCFD) and nature (TNFD) disclosure - governance, strategy, risk management and metrics - including the data to support forward-looking analysis.
  • Supply Chain ESG. We design supplier data collection, estimation and governance for Scope 3 and value-chain disclosure, integrating supplier portals and third-party data into a controlled pipeline.
  • ESG Data Quality. We define and automate quality rules for ESG critical data elements - completeness, factor consistency, unit integrity - so disclosed numbers withstand assurance and audit.
  • Metadata & Lineage. We deliver metadata and end-to-end lineage for every disclosed metric - source to report - giving assurers and auditors the traceability that mandatory ESG reporting now requires.
  • ESG Dashboards. We build role-based dashboards (Power BI, Fabric, Tableau) for sustainability, finance and operations, turning ESG data into ongoing management insight rather than an annual report.
  • Executive Reporting. We produce board- and investor-ready reporting that frames ESG performance, risk and progress against targets in decision-useful terms.
  • ESG AI Analytics. We apply AI - document extraction, Scope 3 estimation, anomaly detection, narrative drafting - on governed data with human oversight, accelerating ESG work without compromising defensibility.
  • Managed ESG Services. For teams building internal capability, we provide an optional retainer - data operations, reporting-cycle support, factor updates and control monitoring - until the function is self-sustaining.

Outcomes

What changes for the business

The first change is credibility: disclosures drawn from governed, traceable data withstand external assurance and audit rather than depending on spreadsheets nobody can reconstruct.

The second is efficiency: pipelines that replace manual collection cut the effort behind each report and the errors that come with it.

The third is readiness: a governed foundation turns tightening regulation into a data-mapping exercise instead of a recurring scramble, so the business stays ahead of requirements.

Together, these shifts turn ESG reporting from a costly, fragile, manual exercise into a governed, efficient, credible capability that stays ahead of regulation rather than scrambling after it.

The business case

How the investment pays back

The sponsor's return is lower cost and higher credibility. Automating collection cuts the substantial manual effort behind each disclosure and the errors that come with it, while governed, traceable data makes every disclosure able to withstand external assurance and audit.

The durable return is readiness: a governed foundation turns each tightening of regulation into a data-mapping exercise rather than a fresh programme, so the business stays ahead of requirements. We map the frameworks you must satisfy to the data first, so the investment targets exactly what matters.

Executive insight

Board considerations

Why ESG reporting is a data problem before it is a disclosure problem.

Govern the data first

Credible disclosure depends on governed, traceable data. Reporting built on ungoverned spreadsheets will not withstand assurance or tightening regulation. In our experience this is the decision sponsors most often wish they had made earlier, because getting it wrong is expensive to unwind.

Automate the collection

Manual gathering is slow, costly and error-prone. Pipelines that replace it reduce effort and raise reliability at the same time. Treating it as a first-class principle rather than an afterthought is what separates programmes that hold up from those that quietly unravel.

Make it auditable

As external assurance becomes the norm, lineage and quality are what let a disclosure survive scrutiny. Build them in rather than bolt them on. It is a small discipline that compounds, protecting both the budget and the credibility of the whole effort.

Prepare for regulation that moves

ESG requirements are tightening and multiplying. A governed foundation turns each new rule into a data-mapping exercise, not a fresh programme. Boards that insist on this find the rest of the programme easier to govern and far easier to defend.

Integrate, do not silo

ESG data sourced from the same operations the business already runs is more credible and cheaper than a parallel ESG data estate. It is the difference between a capability that lasts and one that looks impressive at launch and decays soon after.

What to avoid

Common pitfalls we help you avoid

The failure modes we see most often in this work, and design engagements specifically to prevent.

  • Treating ESG as a reporting exercise on top of ungoverned spreadsheets that will not withstand external assurance.
  • Collecting data by hand every cycle instead of automating the collection that repeats, so effort and error persist.
  • Building a parallel ESG data estate rather than sourcing from the operations the business already runs.
  • Reacting to each new requirement as a fresh programme instead of building a foundation that adapts by data mapping.
The intersection

An integrated capability, not a single specialism

Most firms can claim expertise in one or two of these areas. Our differentiator is the intersection: we bring enterprise data architecture, governance, AI, cloud, deep regulated-industry knowledge and practitioner-grade ETRM expertise together as a single integrated capability, rather than handing a problem between separate specialists who never meet. That combination is uncommon, and it is why the pieces of an engagement are designed to fit.

Enterprise dataarchitectureGovernanceAICloudRegulatedindustriesETRM andtradingIntegrated consultingcapability

Credible ESG reporting depends on data architecture, governance, cloud, the regulatory context of disclosure, and often energy and carbon knowledge, all together. Firms that advise on disclosure without the data engineering, or engineer data without understanding assurance, leave the organisation exposed. Because we hold these together, the foundation is both credible and efficient.

For the sponsor, that means one partner accountable for disclosures that withstand assurance, built on the same trusted foundation as the rest of the business rather than a parallel ESG estate.

Differentiation

Why Durga Analytics

Sustainability consultancies advise on disclosure but not the data engineering beneath it; software vendors sell an ESG tool; internal teams lack the data foundation to make either work. We build the governed data foundation credible reporting needs, and bring three things that requires.

Practitioner-led delivery

We are data engineers who build governed foundations, so ESG reporting rests on real pipelines, lineage and quality rather than a disclosure template. That means fewer surprises at the hard moments, because the people advising you have lived through them, and a design that reflects operational reality rather than an idealised diagram.

Vendor neutrality

We are not selling an ESG platform. We build the foundation on tooling that fits your estate and integrate with the systems you already run. It also means you can trust the recommendation itself, because it carries no hidden incentive, and you keep the leverage that comes from not being tied to one vendor's roadmap.

Integrated ESG, data and governance

ESG data engineering, data governance and energy and carbon analytics sit together, so sustainability reporting draws on the same trusted foundation as the rest of the business. Because these disciplines sit in one team rather than being handed between separate specialists, the pieces are designed to fit, and you deal with one accountable partner rather than a committee of vendors.

Where it applies

Across your sector and estate

ESG data engineering applies wherever regulated, assured sustainability reporting is required, across manufacturing, energy, utilities, retail and financial services. The maturity index gives a common frame for a fast-tightening obligation.

The frameworks you must satisfy and the data sources available differ by sector, so we map obligations to data specifically for you, while the path from manual to integrated is consistent.

Risk management

Risks we manage for you

Sponsors rightly worry about the ways engagements like this go wrong, so we manage the common risks explicitly rather than leaving them to chance. Scope creep is contained by delivering in fixed, valuable slices with agreed success measures, so the programme cannot quietly expand without a decision. Delivery risk is reduced by proving value early on a contained scope before widening, so problems surface while they are small and reversible.

Key-person and knowledge risk is addressed by working alongside your teams and leaving documented, operable artifacts, so the capability does not walk out of the door when we do. Vendor and lock-in risk is managed by staying neutral and designing for the platforms that fit your constraints, so you keep leverage. And the risk of governance or controls decaying after go-live is handled by building them into daily work and, where useful, continuing in a co-managed role so the gains hold.

Working with us

How we engage

Engagements typically begin with a focused discovery and blueprint, a short, fixed-scope phase that baselines the current state, agrees the target and the success measures, and produces a prioritised roadmap a sponsor can fund with confidence.

From there we deliver in thin, end-to-end slices rather than a single monolithic programme, proving value early on a contained scope before widening. This keeps risk visible and reversible and gives leadership real results to point to at each step.

We work alongside your teams throughout rather than in a separate room, so knowledge transfers as we go and the capability we build is one your people can own and extend. Where it helps, we can continue in a co-managed or managed role after the initial build so the gains hold.

FAQ

Frequently asked questions

Do you handle Scope 3 emissions?

Yes. Scope 3 and supply-chain data are among the hardest ESG data challenges; we design foundations that make them tractable and auditable.

Is this reporting or data work?

Primarily data engineering and governance - the foundation that makes credible, auditable reporting possible.

Which frameworks do you support?

We build data foundations that can feed the disclosure frameworks your organization is obligated to, with lineage and quality controls.

Is ESG reporting not mainly a disclosure exercise?

It is a data problem first. Credible, assurance-ready disclosure depends on governed, traceable data, and reporting built on ungoverned spreadsheets will not withstand external assurance or tightening regulation. We build the foundation that makes the disclosure defensible.

How do we cut the manual effort?

By automating the collection that repeats every cycle, which reduces both effort and error immediately, and by mapping obligations to data so effort targets what actually matters rather than everything at once.

Will our disclosures survive external assurance?

That is the design goal. Lineage and quality make each figure traceable and defensible, which is exactly what external assurance now expects, so disclosures rest on evidence rather than on spreadsheets nobody can reconstruct.

Do we need a dedicated ESG platform?

Not necessarily. We build the governed foundation on tooling that fits your estate and source ESG data from the operations you already run, which is more credible and less costly than a separate ESG platform that drifts from operational reality.

How do we stay ahead of tightening rules?

By building the foundation so each new requirement becomes a data-mapping exercise rather than a fresh programme. That is what turns ESG reporting from a recurring scramble into a durable, governed capability.

What is enterprise ESG consulting?

Enterprise ESG consulting helps large organizations build the strategy, operating model, data platform and reporting capability to manage sustainability as a governed business function. It goes beyond disclosure advice to deliver the trusted data, controls and processes that make ESG performance measurable, auditable and decision-useful.

Why is ESG now a business transformation rather than a reporting task?

Because mandatory, assured disclosure requires ESG data to meet financial-grade standards of completeness, control and traceability - which most organizations cannot achieve with spreadsheets. Delivering that means transforming data architecture, governance and operating model, making ESG a genuine enterprise-transformation program, not a reporting add-on.

What is an ESG operating model?

An ESG operating model defines how sustainability runs as a business function: the roles across sustainability, finance, data and business units; decision rights; controls; and the operating rhythm that sustains reporting between cycles. It is what turns ESG from an annual scramble into a repeatable, governed capability.

How do we build an ESG strategy?

Start from material topics and regulatory obligations, define the target operating model and data foundation, and sequence a costed roadmap tied to specific outcomes - regulatory readiness, assurance, target tracking. A credible strategy is anchored in what the data can support, not aspiration alone.

What is a materiality assessment?

A materiality assessment identifies the ESG topics most significant to your business and stakeholders, focusing reporting and data effort where it is decision-useful. It is the foundation that keeps an ESG program scoped and defensible rather than boiling the ocean.

What is double materiality?

Double materiality, required under CSRD/ESRS, assesses both impact materiality - your organization's effect on people and the environment - and financial materiality - how sustainability issues affect your financial performance. A topic is material if it meets either lens, and the assessment must be documented and auditable.

How is ESG governance structured?

ESG governance typically includes board or committee oversight, executive accountability, clear ownership of ESG data and disclosures, policies and controls, and defined decision rights. The goal is to govern ESG data and reporting with the same rigor applied to financial reporting.

Who are the key stakeholders in an ESG program?

Internally: the Chief Sustainability Officer, CFO, CDO, CRO, procurement, operations and the board ESG committee. Externally: investors, regulators, assurers, lenders, ratings agencies and value-chain partners. Effective programs align sustainability, finance and data functions around a shared data foundation.

What is the role of the CFO in ESG?

The CFO is increasingly central to ESG because mandatory reporting is financial-grade, assured and often integrated with financial filings. CFOs own the controls, data integrity and assurance readiness of ESG disclosures, and connect sustainability metrics to sustainable finance, cost of capital and investor relations.

What is carbon accounting?

Carbon accounting is the process of measuring and reporting an organization's greenhouse-gas emissions using standardized methodologies - principally the GHG Protocol. Done well it is a controlled, auditable data process with defined boundaries, methodologies and emission factors, not a one-off spreadsheet estimate.
