ESG Reporting for Finance Teams: What It Is and How to Get Started | Keansa

ESG reporting has moved from a voluntary good-practice exercise to a board-level priority — and in many jurisdictions, a regulatory requirement. Yet for most Finance teams, the mechanics of ESG reporting remain unclear. What exactly needs to be reported? Who owns it? And how does it connect to the financial planning and analysis work Finance already does?

This guide answers those questions plainly. It is written for CFOs, Finance Directors, and FP&A leaders who need to understand ESG reporting — not from a sustainability theory perspective, but from a practical Finance function perspective.

What ESG Reporting Actually Is

ESG stands for Environmental, Social, and Governance. ESG reporting is the process by which an organisation measures, tracks, and discloses its performance across these three dimensions — to investors, regulators, customers, and other stakeholders.

The three pillars cover a broad range of metrics:

Environmental — Carbon emissions (Scope 1, 2, and 3), energy consumption, water usage, waste generation, biodiversity impact, and progress toward net-zero commitments.

Social — Employee health and safety, workforce diversity and inclusion, labour practices across the supply chain, community impact, and human rights policies.

Governance — Board composition and independence, executive compensation structures, anti-corruption policies, data privacy practices, and shareholder rights.

Until recently, most organisations reported on ESG voluntarily and in whatever format they chose. That is changing rapidly. Mandatory disclosure frameworks are being introduced across major markets — and Finance teams are increasingly being asked to own the data infrastructure that supports them.

Why Finance Increasingly Owns ESG Reporting

ESG reporting has historically lived in Sustainability, Corporate Affairs, or HR. But three forces are driving it toward the Finance function — and in most well-run organisations, Finance is already taking the lead.

Investors are treating ESG data like financial data

Institutional investors and rating agencies now scrutinise ESG disclosures with the same rigour they apply to financial statements. They expect the same standards of accuracy, auditability, and consistency. That means ESG data needs the same controls, governance, and verification processes that financial data already has — and Finance is best placed to deliver them.

Regulators are mandating assurance

Under frameworks like the EU's Corporate Sustainability Reporting Directive (CSRD) and the SEC's climate disclosure rules, ESG data will need to be independently assured — in some cases to the same standard as financial statements. That requires audit-ready data trails, consistent methodology, and documented controls. Finance teams already build these for financial reporting.

ESG commitments affect capital allocation

Net-zero targets, renewable energy investments, supply chain sustainability programmes — these are not just communications commitments. They have direct capex implications, affect financing costs, and increasingly influence how analysts value the business. Finance needs to model their impact, which means owning the underlying data.

The Key ESG Reporting Frameworks Finance Teams Need to Know

One of the most common sources of confusion in ESG reporting is the number of competing frameworks. Here are the ones that matter most to Finance teams:

Framework	What It Covers	Who It Applies To
CSRD / ESRS	Mandatory EU sustainability reporting — environmental, social, and governance disclosures across European Sustainability Reporting Standards	Large EU companies and non-EU companies with significant EU operations (phased from 2024–2028)
GRI Standards	Global Reporting Initiative — the most widely used voluntary ESG framework worldwide. Covers economic, environmental, and social topics	Voluntary — used by organisations globally across all industries and sizes
TCFD	Task Force on Climate-related Financial Disclosures — focuses specifically on climate risk and opportunity reporting, scenario analysis, and governance	Increasingly mandatory for listed companies in UK, EU, and other jurisdictions
ISSB / IFRS S1 & S2	International Sustainability Standards Board — global baseline for sustainability-related financial disclosures, building on TCFD	Adopted or under consideration by regulators in 20+ jurisdictions including UK, Singapore, Australia
SEC Climate Rules	US Securities and Exchange Commission climate-related disclosure requirements — Scope 1, 2, and (for large filers) Scope 3 emissions, climate risk governance	US-listed public companies (phased implementation)

For most mid-enterprise organisations, the starting point is understanding which frameworks apply to them based on their listing status, geography, and size — and then building the data infrastructure to support those requirements before the deadlines arrive.

What ESG Data Finance Teams Need to Collect

The most operationally demanding aspect of ESG reporting is data collection. Unlike financial data — which flows from a relatively controlled set of systems — ESG data comes from dozens of sources across the organisation and its supply chain.

Environmental Data

Scope 1 emissions — Direct emissions from sources owned or controlled by the organisation (company vehicles, on-site combustion, manufacturing processes)
Scope 2 emissions — Indirect emissions from purchased electricity, heat, or steam
Scope 3 emissions — All other indirect emissions across the value chain (supply chain, business travel, product use, end-of-life disposal)
Energy consumption by source (renewable vs non-renewable)
Water withdrawal and consumption
Waste generated and disposal methods

Social Data

Total workforce headcount, employment type, and turnover rates
Workforce diversity metrics (gender, ethnicity, age) at all levels including leadership
Health and safety incident rates, lost-time injury frequency
Employee training hours and investment
Pay equity analysis — gender and ethnicity pay gap data

Governance Data

Board composition — independence, diversity, tenure
Executive remuneration structure and ratio to median employee pay
Anti-corruption training completion rates
Whistleblowing policy and incidents
Data privacy incidents and regulatory actions

The Data Challenge — and Why Spreadsheets Don't Scale

Most organisations currently collect ESG data the same way they used to collect financial data — manually, in spreadsheets, with no consistent methodology, no version control, and no audit trail. For a voluntary annual report, this is manageable. For mandatory regulatory disclosure with assurance requirements, it is not.

The specific challenges that make spreadsheet-based ESG data collection unsustainable are:

Why spreadsheet ESG reporting breaks down at scale:

No single source of truth — Different business units use different methodologies, different emission factors, and different data sources. Consolidation is a manual reconciliation exercise.
No audit trail — Regulators and auditors need to trace every number back to its source. Spreadsheets cannot provide that traceability reliably.
No controls — Anyone can change a number in a spreadsheet without it being logged or reviewed. ESG data requires the same change management controls as financial data.
No scenario modelling — Understanding the financial impact of different ESG scenarios (net-zero pathways, carbon pricing, supply chain risk) requires dynamic modelling that spreadsheets cannot support at scale.
No connection to financial planning — ESG commitments have capex, opex, and financing implications that need to be modelled alongside the financial plan — not maintained in a separate document.

How EPM Platforms Support ESG Reporting

This is where the Finance function's existing EPM infrastructure becomes directly relevant to ESG. Modern EPM platforms — Anaplan, Jedox, OneStream — can extend their connected planning capabilities to support ESG data collection, modelling, and reporting.

What EPM platforms bring to ESG reporting specifically:

Centralised data collection — Business units across geographies submit ESG data into a single governed platform, with the same controls and workflows used for financial data collection.

Automated calculations — Emission factor libraries, unit conversions, and methodology rules are built into the model — eliminating manual calculation errors and ensuring consistency across entities.

Audit trail and version control — Every data point, every change, and every approval is logged — meeting the traceability requirements of external assurance.

Integration with financial planning — ESG targets and sustainability investments are modelled alongside financial plans — so the CFO can see the P&L and cash flow impact of ESG commitments in real time.

Scenario modelling — Model the financial implications of different decarbonisation pathways, carbon pricing scenarios, or supply chain sustainability requirements.

Framework-ready reporting — Generate disclosure-ready outputs aligned to GRI, TCFD, CSRD, and ISSB requirements — rather than manually reformatting data for each framework.

A Practical Starting Point for Finance Teams

For Finance teams that are beginning to take ownership of ESG reporting, the priority sequence is consistent across most organisations:

Step 1 — Understand your disclosure obligations

Identify which frameworks apply to your organisation based on listing status, geography, industry, and size. Prioritise mandatory requirements with the earliest deadlines. CSRD phasing, ISSB adoption timelines, and SEC rules all have different applicability criteria — get clarity on what applies before building reporting infrastructure.

Step 2 — Inventory your current data sources

Map where ESG data currently sits across the organisation — utility bills, fleet management systems, HR platforms, supplier databases. Understand what you have, what is missing, and what the quality issues are. This data audit is the foundation of any ESG reporting programme.

Step 3 — Establish governance and ownership

ESG data quality requires clear ownership. Finance typically owns the governance framework and the data infrastructure. Sustainability, Operations, and HR own the underlying data. Define responsibilities, review processes, and escalation paths before building the technology layer.

Step 4 — Build the data infrastructure

Move ESG data collection off spreadsheets and into a governed platform — whether an extension of your existing EPM environment or a purpose-built ESG tool. Prioritise auditability, consistency, and integration with financial planning from the start.

Step 5 — Integrate with financial planning

Ensure ESG targets and sustainability investments are modelled within the financial plan — not maintained in parallel. This is where the CFO's oversight role in ESG is most directly realised: understanding the financial consequences of sustainability commitments before they are made.

The Bottom Line

ESG reporting is no longer a peripheral activity managed by the Sustainability team. It is moving to the centre of the Finance function — driven by investor expectations, regulatory mandates, and the direct connection between sustainability commitments and financial performance.

For Finance leaders, the practical implication is clear: the data infrastructure, governance frameworks, and modelling capabilities that Finance already applies to financial reporting need to be extended to ESG. Organisations that build this infrastructure now — before disclosure deadlines arrive — will be significantly better positioned than those that wait.

The good news is that the EPM platforms Finance teams already use for planning and consolidation are well-suited to support this extension. The foundation is already there — it is a question of building on it deliberately and quickly.
