ESG Reporting Fundamentals

ESG reporting focuses on how companies measure and share their impact on the environment, society, and governance. Accountants play a key role in gathering and verifying this information. ESG reporting is different from traditional financial reporting but requires similar accuracy and transparency.

What Is ESG Reporting

ESG reporting is the practice of disclosing data on environmental, social, and governance factors. It covers areas like carbon emissions, labor practices, board diversity, and ethical conduct. These reports help investors and stakeholders assess a company’s sustainability and risk management.

Regulations are evolving, and many jurisdictions will require ESG reports for compliance. ESG reporting goes beyond financial numbers to show how companies manage non-financial risks and opportunities. Clear, verified data is critical for trust and decision-making.

The Role of Accountants in ESG Reporting

Accountants collect, measure, and verify ESG-related data, ensuring it is accurate and consistent. They apply their skills in data analysis, internal controls, and audit to ESG metrics, similar to their financial reporting duties.

Accountants also help companies align ESG disclosures with legal and market requirements. They work to integrate ESG data into existing reporting systems. Their role is growing as regulators demand more transparency and third-party assurance of ESG information.

Differences Between Financial and Sustainability Reporting

Financial reporting focuses on monetary transactions and results, such as profits and assets. Sustainability reporting, or ESG reporting, deals with qualitative and quantitative information about environmental impact, social responsibility, and governance practices.

ESG data can be less standardized and harder to measure than financial data. It often requires new types of metrics and narratives. Unlike financial reports, which follow strict accounting standards, ESG reporting is still evolving with varied frameworks and guidelines. This makes the accountant’s role in ensuring clarity and reliability crucial.

Key Components of ESG

ESG reporting focuses on measurable factors that affect a company’s impact and operations. These include how a company manages natural resources, treats people, and governs its business. Each area requires clear data and strong policies to meet standards and expectations.

Environmental Considerations

Environmental factors in ESG relate to how a company uses and protects natural resources. This includes energy consumption, waste management, water use, and carbon emissions.

Accountants must track and report these metrics accurately. For example, measuring greenhouse gas emissions is critical as businesses aim to reduce their carbon footprint.

Risk management also plays a role. Companies need to identify environmental risks like climate change effects and regulatory changes. Transparent reporting helps investors understand the company’s sustainability efforts.

Social Responsibility

Social responsibility covers how a company interacts with employees, communities, and customers. Key points include labor practices, diversity and inclusion, health and safety, and community engagement.

Accountants may gather data on employee turnover, workplace accidents, or gender diversity. These figures show commitment to fair treatment and human rights.

Social factors also relate to product safety and customer privacy. Companies with strong social policies can reduce risks of lawsuits and reputational harm.

Governance Factors

Governance involves how a company is directed and controlled. It includes leadership structure, board diversity, ethics, and transparency.

Strong governance means clear policies on executive pay, anti-corruption, and shareholder rights. This builds trust with investors and regulators.

For accountants, governance also means ensuring compliance with financial reporting standards and internal controls. Data accuracy supports responsible management and ethical business practices.

Global ESG Reporting Regulations in 2025

ESG reporting regulations in 2025 now demand clear, detailed disclosures on sustainability issues from companies. These rules affect many public firms and set specific standards for how environmental, social, and governance data is collected, verified, and reported. Companies must adapt to different regimes that vary by region but share the goal of transparency and accountability.

Corporate Sustainability Reporting Directive (CSRD)

The CSRD is a key regulation from the European Union that expands the reporting requirements for public companies and large private firms operating in the EU. It replaces the previous Non-Financial Reporting Directive (NFRD) and applies to more companies, including smaller ones now, with stricter rules.

Under the CSRD, companies must report on sustainability topics using standardized formats. The directive requires assurance of reported data, increasing the role of auditors and accountants. It also expects firms to disclose how ESG factors affect their business and the impact their operations have on society and the environment.

International Sustainability Standards Board (ISSB)

The ISSB was established to create a global baseline for sustainability reporting. It sets standards that help companies across countries provide consistent and comparable ESG information to investors and stakeholders.

In 2025, ISSB standards emphasize financial materiality, meaning companies report ESG information that could affect their value and risks. This approach helps align sustainability disclosure with traditional financial reporting. Many firms use ISSB guidelines to meet local regulations or to improve investor trust through transparent, standardized reports.

Task Force on Climate-related Financial Disclosures (TCFD)

The TCFD framework focuses on climate risks and opportunities in financial reporting. It is widely adopted by governments and companies to guide climate-related disclosures.

Reporting under TCFD includes governance around climate issues, strategy, risk management, and specific metrics like greenhouse gas emissions. Many regulators require or strongly encourage TCFD-aligned disclosures to help investors assess climate risks. Accountants play a critical role in ensuring the accuracy and clarity of this data.

Legislative Trends and Compliance

Around the world, countries are tightening ESG disclosure laws, making compliance more complex and urgent. Regulations often require companies to report on specific topics, such as carbon emissions, social impact, or corporate governance practices.

Key trends include mandatory assurance of ESG data, more frequent reporting deadlines, and penalties for non-compliance. Firms must also track evolving rules across multiple jurisdictions to avoid gaps. Professional accountants need to stay informed and involved in compliance processes to guide their companies through this changing regulatory environment.

ESG Reporting Frameworks and Standards

Effective ESG reporting relies on clear frameworks and standards that guide companies on data disclosure and comparability. These frameworks vary in focus but together create a structure for consistent sustainability disclosure. Understanding how each framework works helps accountants prepare accurate and credible ESG reports.

Global Reporting Initiative (GRI)

The Global Reporting Initiative (GRI) is one of the most widely used sustainability reporting frameworks. It offers sector-specific standards that provide detailed guidance tailored to different industries. GRI focuses on environmental, social, and governance issues by requiring companies to report on impacts material to stakeholders.

GRI standards emphasize transparency and stakeholder engagement. Companies using GRI report on a broad range of topics, including climate change, labor practices, human rights, and governance structures. This helps companies disclose ESG risks and opportunities clearly.

Accountants must understand GRI’s reporting requirements to verify data and ensure the sustainability report meets international expectations. GRI is useful for companies aiming to communicate their ESG impact comprehensively and openly.

Sustainability Accounting Standards Board (SASB)

SASB provides industry-specific standards focused on financially material ESG factors. The goal is to align ESG reporting with traditional financial disclosures so investors can assess risks that affect financial performance.

SASB standards cover 77 industries and highlight key topics like energy management, product safety, and labor conditions. This framework is more targeted than GRI and focuses on data significant for investors rather than broad stakeholder interests.

Accountants play a key role in applying SASB standards by verifying ESG information that integrates with financial reports. This helps companies meet investor demands for reliable, comparable sustainability data. SASB is especially relevant for firms focused on materiality.

Benchmarking and Best Practices

Benchmarking helps companies measure their ESG performance against peers and industry standards. It identifies gaps and opportunities to improve sustainability disclosures and reporting quality.

Best practices include adopting recognized frameworks like GRI and SASB, using third-party assurance, and maintaining clear documentation. Benchmarking also involves tracking ESG metrics regularly and updating reports to reflect changes.

Accountants support benchmarking by providing accurate data and helping interpret ESG metrics. They ensure reports are aligned with evolving standards and competitive within the market. Benchmarking encourages continuous ESG improvement and transparency.

Data Collection and Materiality Assessment

Accurate data collection and clear materiality assessment are critical for reliable ESG reporting. Accountants must identify key issues that affect the business and gather precise sustainability data to meet regulatory and stakeholder expectations.

Materiality in ESG Reporting

Materiality guides what ESG information should be reported. It focuses attention on issues that could influence investors’ decisions or impact a company’s operations.

To determine materiality, companies should engage with stakeholders such as investors, customers, and employees. Internal review processes help identify environmental, social, and governance issues most relevant to the firm’s risk and financial performance.

A formal materiality assessment usually prioritizes topics based on their significance and the company’s ability to manage them. This ensures the report covers the most critical ESG risks and opportunities without including unnecessary details.

ESG Data Collection and Accuracy

ESG data collection must be systematic and accurate to ensure trustworthiness. Companies often gather data from multiple departments, such as procurement, HR, and environmental compliance.

Data should be verified through internal audits or third-party checks to avoid errors and inconsistencies. Clear documentation of data sources and calculation methods is essential for transparency.

Common challenges include incomplete data, inconsistent measurement, and lack of standardized metrics. Implementing strong controls and using digital tools can help improve data quality and ease the reporting process.

Sustainability Data and Metrics

Sustainability data includes information on energy usage, greenhouse gas emissions, water consumption, waste management, and social factors like workforce diversity.

Accountants should track quantitative metrics such as CO2 emissions (tons/year) and water withdrawal (cubic meters), as well as qualitative data like community engagement efforts.

This data must align with frameworks such as the SEC Climate Disclosure Rules or GRI standards, which guide consistent reporting.

Using key performance indicators (KPIs) helps measure progress over time and enables benchmarking against peers or regulatory goals. Clear presentation of these metrics supports better decision-making by stakeholders.

Climate-Related Disclosures

Climate-related disclosures cover emissions data, financial effects of climate risks, and how organizations categorize their emissions. These disclosures help investors and regulators understand an entity’s impact on the environment and potential exposure to climate changes.

Greenhouse Gas Emissions

Greenhouse gas (GHG) emissions reporting is a key part of climate-related disclosures. Companies must measure and report the amount of carbon emissions released from their operations. This includes direct emissions from owned sources and indirect emissions such as electricity consumption.

Accurate GHG data is crucial because it reveals how a company contributes to climate change. Reporting these emissions allows stakeholders to assess a company’s environmental footprint and track progress on reducing emissions over time.

Disclosing emissions also aligns with SEC requirements and growing regulatory demands. Companies must be ready to provide verified data on greenhouse gas emissions to comply and meet investor expectations.

Climate-Related Financial Disclosures

Financial disclosures related to climate focus on risks and opportunities that affect a company’s financial health. These include physical risks from climate change, like extreme weather, and transition risks linked to shifting toward lower-carbon practices.

Companies need to explain how climate risks impact revenue, costs, and assets. For example, possible costs of carbon pricing or investments in cleaner technologies must be reported.

Accountants play a key role in ensuring that financial data related to these risks is accurate and integrated into regular financial reporting. This increases transparency and helps investors make informed decisions.

Scope 1, Scope 2, and Scope 3 Emissions

Emissions are categorized into three scopes to clarify sources:

  • Scope 1: Direct emissions from owned or controlled sources, like factory smokestacks.
  • Scope 2: Indirect emissions from the purchase of electricity, heat, or steam.
  • Scope 3: All other indirect emissions that occur in a company’s value chain, such as supplier activities and product use.

Scope 3 emissions are often the largest and hardest to measure but are critical for a full view of carbon impact.

Understanding and reporting all three scopes gives a clearer picture of total greenhouse gas emissions, helping companies set reduction targets and meet climate-related regulations.

Assurance and Attestation for ESG Reports

ESG reporting is becoming more regulated, requiring verified information on sustainability efforts. Assurance and attestation help ensure the accuracy and reliability of these reports, especially as Scope 3 greenhouse gas emissions reporting shifts from voluntary to mandatory. Understanding the processes and distinctions in assurance is key for CPAs and auditors involved in ESG matters.

Role of CPAs and Auditors

CPAs and auditors play a critical role in validating ESG data. They review a company’s environmental, social, and governance disclosures, offering credibility and transparency to stakeholders. Their work often includes evaluating data collection methods, verifying information, and assessing the company’s adherence to reporting standards.

As mandatory ESG reporting expands, CPAs provide assurance services to help businesses meet legal and investor expectations. They must stay updated on evolving regulations and frameworks to conduct thorough assessments. Their expertise strengthens trust in ESG disclosures and supports better decision-making.

Limited vs. Reasonable Assurance

Assurance can be provided at two main levels: limited and reasonable. Limited assurance involves less extensive testing and provides moderate confidence that the information is free from material errors. It is often chosen for ESG reports due to cost and time efficiency.

Reasonable assurance requires deeper examination and offers a higher level of confidence. It includes detailed testing and evidence gathering. Reasonable assurance is similar to a traditional financial audit in scope but applied to ESG data. Companies with more complex ESG risks usually seek reasonable assurance to meet stricter regulatory or investor demands.

Internal Control and Risk Management

Strong internal control systems are essential to produce accurate ESG reports. Controls include policies and processes that ensure data is properly recorded, monitored, and reported. Auditors evaluate these controls to determine the reliability of ESG information.

Risk management is critical because ESG data can be complex and involve many sources. Companies face risks such as data inaccuracies, fraud, or noncompliance with reporting requirements. Auditors assess how well risks are identified and mitigated to maintain the integrity of the ESG disclosures.

Assurance Engagements

Assurance engagements for ESG reporting follow specific standards guiding how CPAs and auditors conduct their work. These engagements can be attest engagements, where professionals provide a formal opinion on ESG data, or less formal reviews offering insight without direct assurance.

The scope of these engagements can vary. It might cover the entire ESG report or focus on specific areas like greenhouse gas emissions or diversity metrics. Clear engagement terms and defined objectives are essential for delivering reliable assurance. Proper documentation of procedures and findings increases transparency for stakeholders relying on the ESG information.

Reporting Process and Corporate Strategy

The reporting process links closely to a company’s overall strategy. It requires clear plans on managing risks, assessing supply chains, and aligning sustainability with business goals. Accurate data collection and regular updates help make the sustainability report reliable and useful for decision-making.

Integrating ESG Into Corporate Strategy

Companies must embed ESG factors into their core strategies, not just treat them as separate tasks. This means setting measurable goals tied to environmental impact, social responsibility, and governance standards. Clear KPIs ensure progress is trackable.

Leadership plays a key role in integrating ESG. Senior managers should align company values with sustainability outcomes and communicate these priorities across departments. This integration supports better resource allocation and improves overall corporate sustainability reporting.

Sustainability Risks and Liabilities

Identifying risks related to environmental damage, social issues, or governance failures is vital. These risks can create legal liabilities or financial losses if ignored. Companies need to evaluate risks regularly and report on their management.

Effective risk management involves monitoring regulations, potential fines, and public perception. Transparent disclosures about these risks in sustainability reports help build trust with investors and customers. It also protects the company from unexpected liabilities tied to ESG failures.

Supply Chain and ESG Impacts

Supply chains often carry hidden sustainability risks, like poor labor practices or environmental harm. Firms must assess their entire supply chain to understand these impacts. Gathering data from suppliers improves reporting accuracy.

Companies should work with suppliers to enforce ESG standards and reduce negative effects. Addressing supply chain issues strengthens the sustainability report and shows responsibility beyond direct operations. This practice also helps avoid disruptions caused by ethical or environmental problems.

Financial Statement Disclosures

Companies must integrate ESG-related information into their financial disclosures with increasing precision. This involves clear communication about how sustainability factors affect financial results and risks. They also need to consider the role of non-financial data that influences their overall reporting.

ESG-Related Disclosures in Financial Statements

ESG disclosures in financial statements focus on risks, assets, liabilities, and performance affected by environmental, social, and governance matters. Firms must report how climate change, resource use, and other ESG issues impact their financial position and cash flows.

For example, asset impairments tied to environmental changes must be detailed. Companies also need to explain liabilities related to regulatory penalties or cleanup costs associated with sustainability failures.

Regulators increasingly expect ESG risks to be embedded alongside traditional financial data in the notes to financial statements. This ensures transparency about how non-financial factors may affect future earnings.

Non-Financial Reporting Considerations

Non-financial reporting goes beyond traditional financial figures to include metrics such as carbon emissions, workforce diversity, and governance practices. These disclosures complement financial statements but are usually found in sustainability reports or integrated reports.

Companies must balance quantitative ESG metrics with qualitative explanations. This includes policies, goals, and management’s approach to ESG risks.

CPAs should verify the consistency and accuracy of non-financial data, as stakeholders and regulators demand assurance on these reports. Strong non-financial reporting can influence investor confidence and corporate reputation.

Emerging ESG Issues in 2025

In 2025, ESG reporting increasingly centers on specific environmental and social topics. These include the protection of natural environments and aligning corporate activities with global sustainability targets. Companies face growing pressure to provide clear data on these matters.

Biodiversity and Pollution

Accountants must now track how business operations affect biodiversity, including the loss of species and habitats. Reporting requires measuring impacts like deforestation, water contamination, and air pollution. This information helps companies identify environmental risks that could affect long-term value.

Pollution control is closely linked to biodiversity. Firms need to report on emissions of harmful substances and how they reduce their footprint. Transparent data on waste management, chemical use, and pollution levels is critical in ESG disclosures.

Many regulators expect companies to demonstrate efforts to restore ecosystems and reduce pollution. This means connecting financial reports to environmental outcomes, which affects risk assessments and planning.

Sustainable Development Goals (SDGs)

The UN’s Sustainable Development Goals (SDGs) are now a key framework for ESG reporting. Companies are asked to align their strategies with specific goals like clean energy, decent work, and responsible consumption.

Accountants play a role in measuring progress on these goals. This includes tracking investments and social impacts linked to targets such as poverty reduction and climate action. Some SDGs can be quantified through key performance indicators, while others require narrative explanations.

Aligning ESG reporting with SDGs helps companies show their contribution to global sustainability. It also improves transparency for stakeholders and supports compliance with emerging regulatory requirements.
