Introduction
Environmental, social, and governance (ESG) reporting has become an important part of how businesses communicate sustainability performance, manage risks, and respond to the information needs of investors, customers, employees, lenders, and regulators.
For US companies, ESG reporting can involve more than publishing an annual sustainability report. Depending on the business, it may require collecting greenhouse gas emissions data, evaluating climate-related risks, documenting workforce practices, assessing supply-chain impacts, and establishing controls over nonfinancial information.
The challenge is that ESG information often sits across multiple departments, facilities, suppliers, and software systems. Without a consistent reporting process, companies can struggle to produce complete, comparable, and verifiable information.
ESG reporting is the process of measuring, organizing, and disclosing a company’s environmental, social, and governance performance, risks, impacts, and management practices. Reports may follow voluntary frameworks, applicable regulatory requirements, or a combination of both.
This guide explains what ESG reporting means, how it works, which frameworks companies should understand, what US businesses need to know about disclosure requirements, and how to build a reliable reporting process.
What Is ESG Reporting?
ESG reporting is the structured disclosure of information about a company’s performance and practices across three areas: environmental, social, and governance. It helps stakeholders understand how a company manages its environmental footprint, treats employees and other people affected by its operations, and oversees business conduct, risk, and accountability.
Unlike financial reporting, which primarily communicates financial position and performance, ESG reporting addresses a broader set of sustainability-related information. Depending on the reporting purpose and framework, that information may include both quantitative metrics and qualitative explanations.
For example, a manufacturing company might disclose annual greenhouse gas emissions, electricity consumption, workplace injury rates, employee turnover, board oversight responsibilities, and business ethics policies. The company may then explain its targets, actions, and progress against previous reporting periods.
ESG reporting does not automatically mean that a company is sustainable or that its performance is improving. Its purpose is to communicate relevant information transparently so stakeholders can assess performance, risks, and progress.
What are the three pillars of ESG?
| ESG pillar | What it covers | Example metrics and disclosures |
|---|---|---|
| Environmental | Business impacts on the environment and management of environmental risks | GHG emissions, energy consumption, water withdrawal, waste generation |
| Social | Relationships with employees, suppliers, customers, and communities | Workforce diversity, employee turnover, workplace injuries, training, human rights policies |
| Governance | How the company is directed, controlled, and held accountable | Board oversight, business ethics, anti-corruption controls, whistleblower mechanisms |
The metrics a company reports should reflect its industry, material topics, stakeholder needs, and applicable requirements. For example, water consumption may be particularly important for a beverage manufacturer, while data privacy and information security may be more significant for a technology company.
Why Is ESG Reporting Important?
1. Identify and manage business risks
Environmental hazards, resource constraints, supply-chain disruptions, labor practices, and governance failures can affect business continuity and financial performance. Reporting can help companies identify risks, assign responsibility, monitor indicators, and communicate responses.
2. Respond to investor and lender information needs
Investors and lenders may consider material sustainability-related risks when evaluating a company’s long-term prospects and risk management. Consistent reporting can help them understand how the company manages those risks, but does not guarantee access to capital or better financing terms.
3. Meet customer and supply-chain expectations
Large companies may request sustainability information from suppliers as part of procurement, emissions accounting, and risk management. Such requests can create a practical need for reliable ESG data even when a supplier is not directly subject to a particular disclosure requirement.
4. Improve internal accountability
Reporting requires organizations to define metrics, identify data owners, document methodologies, and review performance. These activities can reveal inefficiencies and improve coordination across sustainability, finance, procurement, operations, HR, and compliance.
5. Communicate progress transparently
Consistent reporting allows companies to compare performance across periods, explain changes, and communicate progress toward targets. It also helps identify when performance falls short of expectations.
ESG Reporting vs. Sustainability Reporting vs. CSR
| Term | Primary focus | Typical content |
|---|---|---|
| ESG reporting | Structured information about environmental, social, and governance factors | Metrics, risks, policies, oversight, targets, performance |
| Sustainability reporting | A broader account of sustainability impacts, risks, opportunities, and progress | Environmental and social impacts, economic effects, sustainability strategy |
| CSR | Company policies, commitments, and activities concerning responsibilities to society | Community programs, employee volunteering, charitable initiatives, responsible sourcing |
These concepts overlap. A sustainability report may contain ESG disclosures, while a CSR program may contribute information to the social section of an ESG report. ESG disclosures often emphasize decision-useful information, metrics, risks, and governance, while sustainability reporting can also provide a broader account of impacts on people and the environment.
ESG Reporting Requirements in the United States
There is no single, universal ESG reporting requirement that applies identically to every US company. Applicable obligations depend on factors such as company size, public-company status, industry, jurisdiction, business activities, and contractual relationships. Companies should distinguish legal disclosure obligations from voluntary reporting standards and requests from investors or customers.
Federal disclosure considerations
The US Securities and Exchange Commission (SEC) regulates disclosures made by companies subject to federal securities laws. Public companies may have disclosure obligations concerning material risks, business developments, and other information under existing securities rules.
The SEC adopted climate-related disclosure rules in March 2024. Their implementation was subsequently stayed amid litigation. In May 2026, the SEC proposed rescinding those rules in their entirety. A proposal should not be confused with a completed rescission; companies should consult the SEC’s current rulemaking and litigation updates before making compliance decisions.
Official reference: https://www.sec.gov/newsroom/climate-related-disclosure
SEC 2026 proposed rescission: https://www.sec.gov/rules-regulations/2026/05/s7-2026-19
California climate disclosure laws
California has enacted climate disclosure legislation, including Senate Bills 253 and 261. These laws address greenhouse gas emissions reporting and climate-related financial risk reporting, respectively, for certain covered entities. Their application depends on statutory definitions, company activities, applicable thresholds, and other legal conditions. Implementation and litigation developments can also affect reporting timelines and requirements.
Businesses with relevant connections to California should review current information published by the California Air Resources Board (CARB): https://ww2.arb.ca.gov/. Companies should not assume that operating outside California automatically removes them from consideration; the legal scope must be evaluated against their circumstances.
Industry-specific and other disclosure obligations
Depending on their operations, companies may also need to consider industry-specific requirements, environmental permits, workplace rules, and other laws governing particular disclosures. These obligations are not all ESG reporting regulations in the formal sense, but information collected for compliance may contribute to an ESG reporting program.
Investor, customer, and supply-chain requests
A company may be asked to disclose ESG information by institutional investors, lenders, enterprise customers, or procurement teams. Such requests are not automatically legal mandates, but they can influence whether a company needs a formal reporting process.
Voluntary reporting
Companies may publish ESG or sustainability reports voluntarily using frameworks such as GRI, SASB, or ISSB standards. Voluntary reporting can help establish a consistent baseline and respond to stakeholder questions. Choosing a framework does not, by itself, establish compliance with every applicable law.
Practical recommendation: Create a requirements register identifying the relevant entity, jurisdiction, reporting obligation, reporting period, required metrics, deadlines, and responsible owner. Have qualified legal or compliance professionals verify applicable requirements.
ESG Reporting Frameworks and Standards Compared
Frameworks and standards help companies determine which information to disclose and how to organize it. They serve different purposes: some focus on impacts on the economy, environment, and people; others emphasize sustainability-related risks and opportunities that could affect enterprise value.
1. Global Reporting Initiative (GRI)
The GRI Standards provide a framework for reporting impacts on the economy, environment, and people. They include Universal Standards, Sector Standards, and Topic Standards, and are relevant to organizations seeking a broad sustainability reporting approach.
Reference: https://www.globalreporting.org/standards/
2. SASB Standards
The SASB Standards identify industry-specific sustainability-related disclosure topics and metrics designed to meet investors’ information needs. They are maintained by the IFRS Foundation and can be used with the ISSB framework where appropriate.
Reference: https://sasb.ifrs.org/
3. IFRS Sustainability Disclosure Standards (ISSB)
IFRS S1 establishes general requirements for disclosing sustainability-related risks and opportunities that could reasonably be expected to affect an entity’s prospects. IFRS S2 focuses on climate-related risks and opportunities. Legal applicability depends on adoption or other requirements in the relevant jurisdiction.
Reference: https://www.ifrs.org/issued-standards/ifrs-sustainability-standards-navigator/
4. CDP
CDP operates an environmental disclosure system through which companies and other organizations disclose information on topics such as climate change, water security, and forests. Participation may respond to investor, customer, or supply-chain expectations.
Reference: https://www.cdp.net/
5. Greenhouse Gas Protocol
The GHG Protocol provides widely used standards and guidance for accounting for greenhouse gas emissions. Its Corporate Standard supports organizational emissions inventories, while its Scope 3 Standard addresses emissions across the value chain.
Reference: https://ghgprotocol.org/standards-guidance
Which framework should a US company choose?
| Reporting need | Relevant standard or initiative to evaluate |
|---|---|
| Reporting impacts on people, the environment, and the economy | GRI Standards |
| Industry-specific sustainability information for investors | SASB Standards |
| Sustainability-related financial risks and opportunities | IFRS S1 |
| Climate-related financial disclosures | IFRS S2 |
| Environmental disclosure requests from investors or customers | CDP |
| Corporate greenhouse gas inventory | GHG Protocol |
There is no universally correct framework for every organization. Companies may use more than one standard when objectives overlap. They should map common data points, avoid unnecessary duplication, and document differences in definitions and reporting boundaries.
What Data Does an ESG Report Include?
Environmental data
Environmental reporting may include Scope 1, Scope 2, and relevant Scope 3 emissions; electricity, fuel, and total energy consumption; renewable electricity procurement; water withdrawal, consumption, and discharge; waste generated, diverted, recycled, or disposed of; environmental incidents; and climate-related risks and targets.
Social data
Social reporting may include total workforce and employee turnover; workforce diversity metrics where appropriate and lawful; training hours; workplace injuries and safety performance; human rights policies and due diligence; supplier labor standards; and customer privacy or product safety where relevant.
Governance data
Governance reporting may include board and management oversight; ethics and anti-corruption policies; whistleblower and grievance mechanisms; risk management responsibilities; relevant compliance incidents; and sustainability targets, incentives, and accountability structures.
Example ESG reporting metrics
| Metric | Illustrative unit | Potential data source |
|---|---|---|
| Scope 1 emissions | Metric tons of CO₂e | Fuel records, fleet data, refrigerant records |
| Scope 2 emissions | Metric tons of CO₂e | Electricity invoices and emissions factors |
| Electricity consumption | kWh or MWh | Utility invoices and meter data |
| Water consumption | Cubic meters | Water bills and facility meters |
| Waste generated | Metric tons | Waste contractor records |
| Employee turnover | Percentage | HR information system |
| Recordable workplace incidents | Count or applicable incident rate | Occupational health and safety records |
| Employee training | Hours per employee | Learning management system |
| Board oversight | Narrative disclosure | Board charters and meeting records |
| Ethics training completion | Percentage of relevant employees | Compliance training records |
These are examples, not a universal mandatory disclosure list. Definitions, calculation methods, organizational boundaries, and reporting periods should be documented before metrics are compared.
Understanding Scope 1, Scope 2, and Scope 3 Emissions
Greenhouse gas accounting is often one of the most data-intensive parts of ESG reporting. The GHG Protocol distinguishes three scopes:
Scope 1: Direct emissions from sources owned or controlled by the company, such as fuel burned in company-operated boilers, industrial processes, or company vehicles.
Scope 2: Indirect emissions associated with the generation of purchased or acquired electricity, steam, heating, and cooling consumed by the company.
Scope 3: Other indirect emissions across the company’s value chain, such as purchased goods and services, business travel, employee commuting, transportation, and the use or disposal of sold products, where applicable.
Reference: https://ghgprotocol.org/standards-guidance
Scope 3 data collection can be challenging because information originates outside a company’s direct operational control. Companies may use supplier-specific data, activity-based calculations, industry averages, or other estimation methods. The method and its limitations should be documented transparently.
How to Prepare an ESG Report: A Step-by-Step Process
Step 1: Define the reporting objective and scope
Determine whether the objective is regulatory disclosure, customer questionnaires, a sustainability report, or investor communication. Identify the entities, subsidiaries, facilities, activities, and reporting period covered.
Step 2: Identify applicable requirements and stakeholders
Create an inventory of relevant legal obligations, voluntary frameworks, investor requests, customer questionnaires, and contractual requirements. Identify intended readers and their information needs.
Step 3: Conduct a materiality assessment
Assess relevant sustainability impacts, risks, and opportunities. Impact materiality and financial materiality are distinct concepts; use the approach required by the chosen framework and document the methodology and decisions.
Step 4: Select the reporting framework
Choose standards that match the company’s objectives. Map required disclosures against available data and identify overlapping metrics and differences in definitions.
Step 5: Identify data owners and sources
Assign responsibility for each metric. Document source systems, owners, reporting frequency, units, and required evidence.
Step 6: Collect and calculate ESG data
Collect information from invoices, meters, business systems, supplier questionnaires, HR platforms, and other records. Apply consistent methods, conversion factors, and reporting boundaries.
Step 7: Validate data and retain evidence
Check missing values, inconsistent units, unusual changes, duplicate records, and calculation errors. Investigate discrepancies and retain source documents and calculation records.
Step 8: Review and approve disclosures
Have sustainability, finance, legal, compliance, and management teams review disclosures according to their responsibilities. Prepare supporting documentation for assurance where applicable.
Step 9: Publish and communicate the report
Present the information clearly, explain the reporting boundary and methodology, identify applicable standards, and disclose material changes and limitations.
Step 10: Improve the next reporting cycle
Review data delays, estimates, and process gaps. Improve ownership, systems, controls, and collection timelines.
ESG Data Collection Challenges and How to Solve Them
| Challenge | Why it matters | Practical solution |
|---|---|---|
| Data is spread across departments | Teams may submit different formats or miss deadlines | Create a central data inventory, named owners, and common templates |
| Inconsistent definitions | The same metric may be calculated differently across facilities | Document metric definitions, boundaries, and methodologies |
| Missing supplier data | Value-chain emissions and supplier metrics may be difficult to quantify | Prioritize relevant suppliers, standardize questionnaires, document estimates |
| Manual spreadsheet processes | Repeated copying and editing can introduce errors | Automate repeatable imports and validation where practical |
| Limited supporting evidence | Reviewers may not trace a figure to its source | Maintain source documents, calculation records, approvals, and version histories |
| Unclear accountability | Teams may not know who owns a disclosure | Assign metric owners and escalation procedures |
| Changing requirements | Teams may use outdated definitions or overlook new obligations | Maintain a requirements register and schedule periodic reviews |
These challenges are interconnected. Automating a spreadsheet does not solve inconsistent definitions, and collecting more supplier data does not automatically make it reliable. Effective programs combine clear ownership, consistent methodology, appropriate technology, and review controls.
What Does an ESG Report Look Like?
An ESG report should be organized around its reporting objective, applicable framework, and audience. A company could adapt the following structure:
Executive summary: key sustainability topics, performance highlights, and priorities.
Company overview: business activities, organizational boundaries, and reporting period.
Reporting methodology: frameworks used, materiality approach, assumptions, and limitations.
Governance: board oversight, management responsibilities, and risk management.
Environmental performance: emissions, energy, water, waste, and relevant environmental impacts.
Social performance: workforce, health and safety, training, human rights, and supplier practices.
Targets and progress: baselines, targets, current performance, and explanations of changes.
Data tables and supporting disclosures: metrics, units, methodologies, and evidence.
Assurance and controls: external assurance details where applicable and relevant reporting controls.
Appendix: definitions, framework indexes, calculation notes, and additional disclosures.
Illustrative ESG performance table
| Metric | Year 1 | Year 2 | Change |
|---|---|---|---|
| Scope 1 emissions | 1,000 tCO₂e | 900 tCO₂e | -10% |
| Scope 2 emissions | 2,000 tCO₂e | 1,800 tCO₂e | -10% |
| Electricity consumption | 5,000 MWh | 4,700 MWh | -6% |
| Waste generated | 500 metric tons | 450 metric tons | -10% |
Illustrative data only. These figures do not represent Credibl ESG or any actual company’s performance. A published report should explain the organizational boundary, calculation methodology, and reasons for significant changes, including changes in production, acquisitions, divestitures, or calculation methods.
ESG Reporting Best Practices
Establish clear ownership
Assign a responsible person to each material metric and disclosure. Define who collects, reviews, approves, and submits information.
Use consistent methodologies
Document metric definitions, reporting boundaries, units, emissions factors, assumptions, and estimation methods. Explain material methodology changes.
Maintain traceable records
Keep source documents, calculations, approvals, and corrections organized so reported figures can be traced to their origins.
Integrate ESG data into business processes
Where practical, incorporate sustainability data collection into procurement, finance, facilities, HR, and risk management workflows.
Prioritize material information
Focus on disclosures relevant to impacts, risks, opportunities, and applicable requirements. Explain the significance of reported metrics.
Set measurable targets
Define the metric, baseline year, target year, organizational boundary, and measurement method. Explain material deviations.
Review requirements regularly
Monitor relevant regulatory developments, framework updates, and stakeholder expectations.
Prepare for assurance
Where assurance is required or planned, establish suitable controls, evidence retention, calculation documentation, and review procedures. Do not claim independent assurance unless it has occurred.
How ESG Reporting Software Can Help
As a reporting program grows, managing ESG data through disconnected spreadsheets and email requests can become difficult. ESG reporting software can help centralize data, standardize collection, assign responsibilities, apply validation rules, track supporting evidence, and prepare information for different disclosures.
Depending on the platform, capabilities may include centralized ESG data collection, automated imports and validation, greenhouse gas accounting, supplier engagement, framework mapping, audit trails, approvals, and performance dashboards.
Software does not automatically guarantee accurate data, regulatory compliance, or assurance. Companies still need appropriate methodologies, internal controls, qualified reviewers, and oversight.
When should a company consider ESG reporting software?
A dedicated platform may be worth evaluating when a company manages multiple facilities, receives recurring customer questionnaires, reports under several frameworks, relies on extensive supplier data, or struggles to trace disclosures to source evidence.
Before selecting a platform, evaluate supported frameworks, data integrations, emissions methodologies, access controls, audit-trail capabilities, reporting workflows, and the ability to accommodate the company’s organizational structure. The goal is to make the underlying reporting process more consistent, traceable, and repeatable.

How Credibl ESG Helps Companies Manage ESG Reporting
Credibl may be relevant to companies managing ESG data across multiple locations, business units, or suppliers; organizations responding to recurring customer or investor questionnaires; and teams preparing disclosures across multiple frameworks. It can also support organizations seeking clearer ownership, stronger evidence trails, and a more repeatable reporting cycle.
Who can benefit from Credibl ESG?
Credibl also offers ESG consulting, advisory, and data-concierge services. Depending on the organization’s needs, this support can help with reporting strategy, data collection planning, materiality-related work, gap assessment, and the practical coordination required to prepare disclosures. The right scope depends on the company’s reporting objectives, internal resources, and applicable requirements.
Combine technology with ESG expertise
Beyond preparing a report, companies need to understand performance and track progress. Credibl offers ESG dashboards, KPI monitoring, goal and project tracking, and AI-supported data insights to help teams review trends, investigate variances, and monitor progress against targets. Supplier assessment capabilities can also help organizations gather information beyond their direct operations where value-chain data is relevant.
Turn ESG data into insights and action
Organizations may need to respond to more than one framework, questionnaire, or stakeholder request. Credibl supports multi-framework reporting workflows so teams can organize common data and reuse it where the underlying definitions and reporting boundaries are compatible. This can reduce unnecessary duplication and help teams maintain a more consistent source of ESG information. Companies should still confirm which disclosures apply to them and review framework-specific requirements before publishing.
Connect data to reporting frameworks and disclosures
A report is only as reliable as the information behind it. Credibl supports evidence-backed data collection, validation checks, variance flags, review workflows, comments, approval tracking, and audit logs. These capabilities help teams identify missing or unusual values, retain supporting documentation, and maintain a clearer record of how figures were reviewed. They can also help companies prepare for internal review or external assurance, although software alone does not guarantee that data is accurate or that a report will pass assurance.
Improve data quality and traceability
Credibl helps organizations bring ESG information into a structured, centralized workflow rather than relying entirely on disconnected spreadsheets and email requests. Teams can assign data points to owners, coordinate submissions across business units, and use integrations and data-import capabilities to reduce repetitive manual work. The platform supports a broad set of ESG KPIs and can accommodate custom KPIs, helping companies organize environmental, social, and governance information around their reporting needs.
Centralize ESG data collection
Producing a reliable ESG report requires more than drafting disclosures at year-end. Companies need a repeatable way to gather data from business units, facilities, finance, HR, procurement, operations, and suppliers; validate the information; document its origin; and map it to the disclosures they need to prepare. Credibl ESG supports this process through an end-to-end ESG data management and reporting platform, complemented by ESG expertise and guided support.
Conclusion
ESG reporting provides companies with a structured way to measure and communicate environmental, social, and governance performance, impacts, risks, and management practices.
For US businesses, the first step is to understand which requirements and stakeholder expectations apply. The next is to establish a reporting process built around material topics, consistent methodologies, clear data ownership, reliable evidence, and appropriate review controls.
The quality of an ESG report depends on the quality of the information and processes behind it. By treating ESG data collection as an ongoing business process rather than a last-minute reporting task, organizations can improve consistency, strengthen accountability, and prepare more useful disclosures.
As reporting needs evolve, the combination of clear governance, well-defined metrics, and suitable technology can help companies maintain a more reliable and repeatable approach to ESG reporting.
