The field of environmental, social and governance reporting and assurance is a natural opportunity for accountants, and one that’s ripe for the taking. But they risk losing the opportunity if they don’t move more quickly.
Incoming and evolving regulation from the European Union and in some U.S. states means more companies will be looking for attestation that their climate and other initiatives are actually effective. Accounting firms are at varying stages with ESG, with the biggest firms having invested billions in this area and smaller firms just getting started. However, there’s still hesitancy among many firms.
There are three key areas of regulations to watch: the Corporate Sustainability Reporting Directive in the EU, the proposals from the Securities and Exchange Commission in the U.S., and American state regulation, specifically from California.

With the new presidential administration, experts anticipate that the SEC will table or even rescind its proposed regulation. But EU regulations are expected to impact as many as 3,000 private and public U.S. companies, and proposed regulation in California will impact all companies that do business in the Golden State.
“What we always talked about previously was, ‘We have this alphabet soup of standards and frameworks and nobody knows what to do,'” KPMG US sustainability leader Maura Hodge said. “But what we’re actually finding is that it’s creating a patchwork of complexity, so while it’s more organized, it is still very complicated.”
“I think that there is a desire on the preparers’ part to continue to pump the brakes on this and say, ‘We don’t want to go all in because everything keeps changing and we aren’t sure if it’s going to be required or mandated or not,'” Hodge said. “But what we have been advising and the reality is that this needs to happen. Most of these companies have been reporting voluntarily historically anyway, and I think there’s a recognition and a realization that transparency and accountability in that reporting is what is desired.”
“At a minimum, shifting what you’ve done in the past to get to this regulatory baseline is a no-regrets move that you kind of keep working forward to,” she added.
Highly transferable skills
Accountants are well-suited to performing this service as ESG reporting and assurance moves away from the marketing and investor relations side of companies and becomes a financial function with regulation and standards.
Though accountants may need upskilling in specific sustainability topics, Ami Beers, senior director of the assurance and advisory innovation team at the American Institute of CPAs, says the foundational processes and skills are highly transferable, like understanding different standards and frameworks, gathering data from multiple sources, pulling together reports, and implementing processes and controls and governance.
“We have been collectors of data and auditing of that data for millennia now. We’ve been doing it with financial data. It only makes sense that we could do it with nonfinancial data. We already have frameworks set up that we adhere to for really high-quality work and high-integrity work, which ESG is in general,” said Jennifer Harrity, ESG and sustainability leader at Top 100 Firm Sensiba.
“Accounting firms are very good with the quantifiable data, but the qualitative data is scarier for them because that’s not normally where they live,” Harrity said. “But when you look at it, this is data that you look at opportunities and risks and that’s what accountants have been really good at for a very long time — looking at the numbers and having it tell a story, being able to tell that story to the clients in order to see what is opportunities and risks for an organizations. When paired with the financial data, it’s an extremely impactful forecast, and it’ll allow you to forecast for your clients with a much longer look into the future than just financial data alone.”
Where to start with ESG
With an ongoing talent shortage, firms may feel at a loss on how to start a whole new practice when they still have their traditional compliance work to complete. Starting with a materiality assessment using the Sustainability Accounting Standards Board’s framework is a good place to start, Harrity said.
“Don’t just jump into the practice. Figure out what you want to help your clients with in the ESG space and run through it yourself as a firm,” Harrity said. “One of the things that we did is we said we’re not going to offer any services or tools to our clients that we have not put ourselves through, and I think once you start doing that, you start to really see the value of ESG from an owner standpoint and from an organizational standpoint.”
Establishing good governance practices cannot be overlooked, either. Oftentimes, standard operating procedures aren’t written down — they live in an individual employee’s or a collective’s head.
“If the person who’s responsible for collecting this data were to wake up tomorrow and not be able to come to work, would somebody else be able to know what they were doing and be able to recreate that information?” Hodge said.
After ensuring there is solid governance, then firms can layer controls on top.
“What’s really important to remember — we talk about this all the time with controls on the financial reporting side — is that the company needs to be doing that before their assurance providers come in,” said KPMG’s Hodge. “Because while we perform some of the same procedures, you don’t want the assurance provider to find those mistakes. You want to have identified them and resolved them prior to the assurance provider coming in, or else it just makes the process longer.”
As the profession moves from a compliance to an advisory model, with developing technology like artificial intelligence taking over the compliance side, ESG is an opportunity for firms to add a revenue-generating service to their consulting and advisory arsenals. But this opportunity won’t be around for long.
“There are a lot of sustainability consulting firms, not accounting firms, that are chomping at the bit for this work. If accounting does not get their butts together, it’s ours to lose,” Harrity said. “This business and this niche could be a really powerful additive to our firms, but if we linger, those sustainability firms are going to swoop in and really dominate the space, and it’s going to be hard for us to come back in.”
The accounting profession is undergoing a fundamental structural transition as enterprise finance departments shift from periodic month-end closes toward automated continuous accounting models. By integrating specialized machine learning algorithms directly into enterprise resource planning (ERP) platforms, chief accounting officers are transforming financial reporting from a retrospective exercise into a real-time operational asset.
The Shift from Periodic Close to Continuous Financial Reporting
Traditional accounting workflows heavily relied on manual data reconciliation, spreadsheet calculations, and multi-week closing cycles at the end of each fiscal period. In contrast, continuous accounting frameworks utilize automated software agents to process, validate, and post transactional data in real time as business activities occur.
Automated bank reconciliation tools cross-reference incoming bank feeds, invoice records, and purchase orders automatically. By resolving transactional variances instantly throughout the month, corporate accounting teams eliminate the traditional workload spikes associated with quarterly and annual closes.
Machine Learning in Audit Trails and Anomaly Detection
Advanced natural language processing (NLP) and machine learning tools are redefining internal audit and financial control environments. Automated systems analyze 100% of general ledger entries, identifying anomalous transactions, duplicate payments, and unauthorized journal entries in real time.
Rather than relying on random statistical sampling, corporate internal auditors can focus their attention on high-risk flags automatically surfaced by algorithmic monitoring platforms. This continuous risk assessment strengthens internal controls over financial reporting (ICFR) and significantly reduces fraud risk.
Evolving Roles for Accounting Professionals
As routine data entry and manual reconciliation tasks become fully automated, the skill set required for accounting professionals is shifting toward data analysis, system design, and strategic business advisory.
– Systems Governance: Accountants are increasingly responsible for monitoring algorithmic accuracy and managing data integration pipelines.
– Business Partnership: Finance professionals leverage real-time financial dashboards to advise operational leaders on margin management and working capital allocation.
– Regulatory Compliance Management: Accounting teams utilize automated platforms to ensure compliance with dynamic tax codes and international accounting standards.
Core Implementation Recommendations
1. Deploy Automated Reconciliation Tools: Integrate continuous transaction processing modules into existing enterprise ERP architectures.
2. Establish Algorithmic Governance Controls: Implement strict internal testing protocols to ensure automated accounting rules comply with GAAP/IFRS standards.
3. Reskill Accounting Teams: Invest in training finance staff on data analytics, workflow automation, and predictive financial modeling.
Corporate accounting departments face expanding reporting expectations as international sustainability disclosure standards achieve regulatory enforcement across major global jurisdictions. Chief Accounting Officers (CAOs) and corporate controllers are establishing rigorous internal accounting controls to treat Environmental, Social, and Governance (ESG) metrics with the same data precision, auditability, and governance as traditional financial statements.
Regulatory Harmonization Under Global Sustainability Frameworks
The implementation of standardized sustainability reporting frameworks—notably rules established by international sustainability accounting boards—has created unified expectations for public and large private enterprises. Corporations must report standardized metrics covering greenhouse gas emissions (Scope 1, 2, and material Scope 3), energy utilization, workforce demographics, and supply chain governance.
In Europe and other participating international jurisdictions, double materiality principles are mandatory. Under double materiality, organizations must report both how external sustainability risks impact corporate financial performance, and how internal corporate operations affect surrounding environmental and social structures.
Integrating Sustainability Metrics into Core ERP Systems
To provide auditable non-financial data, enterprise organizations are integrating specialized carbon accounting and ESG management platforms directly into core ERP systems. Automated data collectors capture energy utility invoices, logistics fuel consumption metrics, and vendor compliance records in real time.
Establishing automated, traceable data pipelines ensures that non-financial reporting is supported by clear audit trails. This structured approach allows external financial auditors to provide reasonable assurance on sustainability disclosures during annual corporate reporting cycles.
Financial Impacts and Capital Market Disclosure
Accurate ESG reporting directly influences corporate cost of capital and institutional credit ratings. Commercial lenders and institutional asset managers systematically incorporate sustainability metrics into risk pricing models. Companies that demonstrate transparent, verifiable progress in operational energy efficiency and climate risk mitigation benefit from expanded access to green bond markets and lower debt pricing.
Action Steps for Accounting Leadership
1. Implement Double Materiality Frameworks: Conduct comprehensive assessments to identify material financial and operational sustainability metrics.
2. Build Auditable Non-Financial Data Pipelines: Automate ESG data collection within core accounting software to ensure data integrity.
3. Align Sustainability with Annual Financial Filings: Prepare non-financial disclosures concurrently with financial statements to satisfy regulatory audit expectations.
Internal audit departments and corporate risk managers are modernizing internal control frameworks by shifting from periodic sampling techniques to continuous monitoring and machine learning analytics. As operational data volumes increase across enterprise organizations, automated control testing ensures financial integrity, prevents corporate fraud, and streamlines annual audit engagements.
The Limitation of Periodic Audit Sampling
Historically, internal and external auditors evaluated internal controls by reviewing random samples of financial transactions—often analyzing less than five percent of total ledger entries. In complex enterprise environments, periodic sampling methods carry inherent risks of overlooking localized financial misstatements, unauthorized disbursements, or operational control breakdowns.
In 2026, progressive internal audit functions are utilizing automated continuous monitoring platforms that evaluate one hundred percent of financial transactions in real time. Continuous control auditing systems continuously monitor general ledger entries, procurement approvals, and expense reimbursements across all operating subsidiaries.
AI-Powered Fraud Detection and Anomaly Identification
Machine learning models trained on historical corporate financial data excel at identifying subtle transactional anomalies that indicate potential fraud or operational error. Automated systems instantly flag duplicate invoice payments, unapproved vendor creation, unusual journal entry timing, and unauthorized override of authority thresholds.
When an anomaly is detected, the automated auditing platform generates an instant risk alert, allowing internal audit teams to investigate root causes immediately. Early detection prevents minor operational errors from escalating into material weaknesses in financial reporting.
Streamlining External Audit Preparation
Continuous internal control monitoring delivers significant benefits during annual external financial audits. External audit firms can review continuous audit logs and automated control testing documentation, reducing the time required for manual field testing.
This integrated approach lowers overall audit compliance fees, reduces administrative burdens on corporate accounting staff, and provides senior management and audit committees with real-time visibility into the organization’s overall risk profile.
Core Implementation Guidelines
1. Transition to 100% Data Testing: Replace legacy sampling methods with automated continuous audit monitoring systems.
2. Deploy Anomaly Detection Algorithms: Implement machine learning models to identify unauthorized transactions and operational control overrides.
3. Align Internal and External Audit Workflows: Coordinate continuous control testing protocols with external auditors to optimize annual compliance cycles.
