Investors, regulators, enterprise customers, and banks increasingly expect companies to report on sustainability risks, environmental impact, and governance practices—an expectation that is now the norm, but meeting it isn’t simple. Environmental, social, and governance (ESG) frameworks exist to give that reporting structure and consistency. The problem is that the ESG space includes dozens of overlapping frameworks, standards, benchmarks, and rating systems, each targeting a different audience—investors, regulators, and supply chain partners, to name a few. Many companies therefore choose several, because no single framework covers everything. This article breaks down the primary options, explains when each applies, and shows how the right technology can transform ESG reporting from a recurring fire drill into a repeatable process.

What Are ESG Frameworks?

ESG frameworks are how companies identify, organize, measure, and disclose ESG information to stakeholders, such as investors, regulators, customers, and employees. Companies use frameworks to determine which sustainability data matters most and how to assess material issues, such as climate risk and corporate governance. Frameworks also standardize the way ESG reports are presented.

ESG frameworks vary widely. Some provide overarching principles and reporting architectures, while others define specific metrics and disclosure requirements. For example, for investors, the International Sustainability Standards Board (ISSB) publishes disclosure standards under the International Financial Reporting Standards’ IFRS S1 and IFRS S2. On the regulatory side, the European Union’s (EU’s) Corporate Sustainability Reporting Directive (CSRD) and its accompanying European Sustainability Reporting Standards (ESRS) legally require certain companies to disclose sustainability information. Then there are benchmark systems, such as the Global Real Estate Sustainability Benchmark (GRESB) and the CDP, which run disclosure programs that support external comparisons. Understanding what each framework prioritizes—and which ones apply—is the starting point for building a strong reporting program.

Key Takeaways

  • Even companies that aren’t directly regulated face ESG data requests from enterprise customers, lenders, and investors.
  • ESG frameworks structure how organizations measure sustainability information and disclose it to investors, regulators, customers, and other stakeholders.
  • Frameworks provide an overarching logic for reporting and standardizing specific metrics and disclosure requirements.
  • Choosing a framework depends on the primary audience; investor-focused reporting requires a different approach from broad impact reporting or sector-specific benchmarks.
  • ERP and financial systems that tie sustainability data to finance and operations reduce manual effort and simplify audits.

ESG Frameworks Explained

ESG frameworks translate broad sustainability goals into specific disclosures and metrics for companies and their stakeholders to evaluate and compare. Think of them as an operating system for ESG reporting that defines what information matters, who needs it, and when. Without a framework, companies could inadvertently publish sustainability claims that are inconsistent or impossible to verify. Disclosures may also be selective (for example, highlighting wins but omitting problems). Frameworks, on the other hand, connect sustainability data to formal disclosures about ESG risks, opportunities, impacts, and targets in ways external and internal stakeholders can actually evaluate.

ESG frameworks have become more complex as stakeholders demand increasingly specific information. Investors want to understand how sustainability factors affect financial performance and risk—what’s often called “financial materiality.” Regulators, particularly in the EU, have pushed for “double materiality,” which also takes into account a company’s impacts on people and the environment, regardless of whether those impacts affect the bottom line. Meanwhile, customers and supply chain partners often seek operational data, such as carbon emissions and labor practices, so they can meet their own reporting obligations or procurement standards. Employees and communities add yet another layer: broader social and environmental commitments that don’t fit neatly into investor- or regulatory-focused disclosures.

Companies often need to apply more than one framework simultaneously: one framework for investor communications, another for regulatory compliance, a third to address customer or supply chain needs, and a fourth for internal decision-making. The challenge is how to achieve this efficiently, without duplicating work or running parallel data systems.

ESG Frameworks vs. ESG Standards

The terms “framework” and “standard” often get used interchangeably. The distinction matters less than understanding what each one actually requires.

Frameworks generally provide the top-level structure—the organizing principles and disclosure categories—that guide reporting and audit readiness. Sustainability data that follows a recognized framework is easier to document and verify, and makes third-party assurance more straightforward.

The Task Force on Climate-related Financial Disclosures (TCFD) was the classic example of a framework. It disbanded in 2023 after fulfilling its remit, but, in its day, it organized climate disclosures around the four pillars of governance, strategy, risk management, and metrics/targets without specifying exactly what to measure. Standards take the next step by defining specific disclosure expectations, and several are built directly on TCFD’s architecture. These include the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), the IFRS Sustainability Disclosure Standards (IFRS S1 and S2), and the ESRS.

Why Are ESG Frameworks Important?

Without an ESG framework, sustainability claims are just that: claims. Frameworks give them structure, consistency, and something stakeholders can actually verify. Without them, companies would be able to publish sustainability claims that are uncomparable or impossible to verify. With them, they can connect sustainability data to formal disclosures about risks, opportunities, impacts, and targets in ways that external stakeholders can easily evaluate.

Midmarket companies often assume they’re too small to benefit from frameworks. In reality, ESG disclosure increasingly flows upstream through supply chains and financing relationships. That makes frameworks relevant far outside the Fortune 500. Even companies not directly subject to regulations like CSRD are often asked by their customers or business partners for carbon emissions data and supplier due diligence documentation—and, increasingly, governance information, such as board oversight and ethics policies. To help these smaller organizations respond, the EU’s Voluntary Standard for Small and Medium-sized Enterprises initiative and CDP’s Small and Medium-sized Enterprises (SME) questionnaire are specifically designed for organizations in value chains.

Frameworks can deliver value beyond compliance. More than two-thirds of companies already reporting under CSRD or ISSB gained significant or moderate value beyond compliance from the data and insights collected, according to PwC’s “2025 Global Sustainability Reporting Survey.” That might mean spotting supply chain vulnerabilities early or finding ways to cut costs in energy and materials.

Benchmark ESG Frameworks and Standards

Disclosure frameworks tell you what to report. Benchmarks tell you how you stack up. For some audiences, the latter is the one that matters most. They don’t just provide a disclosure; they give it some relative context. Unlike disclosure frameworks that serve as a structure for what gets reported, benchmarks look at how well companies perform compared to peers. That comparative lens makes them particularly valuable for competitive positioning and capital allocation decisions. Organizations in real estate and infrastructure, for example, utilize benchmarks to allow investors and customers to compare entities, using common scoring methodologies.

Global Real Estate Sustainability Benchmark (GRESB)

This investor-driven benchmark focuses on real estate and infrastructure. As of 2025, 1,002 fund managers had submitted 2,382 assessments, including 239 entities in the inaugural residential component. GRESB offers validated data that’s particularly relevant for property-intensive sectors, such as hospitality and retail.

Carbon Disclosure Project (CDP)

CDP, one of the most important environmental disclosure systems, sits at the intersection of climate reporting, procurement pressure, and capital markets. More than 22,000 large companies—representing nearly two-thirds of global market capitalization—participated in 2025. In addition, CDP’s SME questionnaire drew nearly 11,000 disclosures from smaller companies that year, as well. CDP’s strength is its translation of ESG goals into concrete asks—emissions data, climate risks, targets, water, forests, and supply-chain reporting.

Principles for Responsible Investment (PRI)

PRI is a principle-based framework for investors and asset owners, not operating companies. But it matters to businesses, because PRI signatories, representing more than US$139 trillion in assets under management as of 2024–25, incorporate ESG factors into their investment decisions. If a company’s investors or lenders are PRI-aligned, they’re factoring ESG into their investment decisions, which means the quality of its ESG data can directly affect access to capital and the terms of financing. The same applies to potential acquirers conducting due diligence.

Regulatory ESG Frameworks and Standards

Regulatory ESG frameworks are where voluntary disclosure becomes mandatory compliance. They help companies manage legal reporting obligations, filing deadlines, assurance requirements, and, in some cases, penalties for noncompliance. For accountants and compliance officers, regulatory ESG most closely resembles financial reporting, with controls, evidence trails, reconciliations, and audit readiness. But the specifics depend on where a company operates. The EU, UK, and Australia each take distinct approaches to mandatory sustainability disclosure.

Corporate Sustainability Reporting Directive (CSRD)

This EU directive requires large, in-scope companies to disclose sustainability-related risks and opportunities. It also requires disclosure of impacts on people and the environment—the “double materiality” standard. The first companies to comply with CSRD published their inaugural reports in 2025. The regulation continues to evolve, however, with an omnibus simplification package proposing to narrow the scope to companies with more than 1,000 employees.

European Sustainability Reporting Standards (ESRS)

These disclosure standards under CSRD were developed with technical input from the European Financial Reporting Advisory Group. They cover ESG topics with specific data-point requirements, including how to assess materiality and how far into the supply chain to go to collect data. Companies working with ESRS frequently find that compliance becomes as much a data architecture issue as a reporting one, because it requires tracking hundreds of hyper-granular, non-financial data points across often siloed enterprise systems.

Streamlined Energy and Carbon Reporting (SECR)

SECR is the UK’s mandatory energy and carbon reporting framework for UK-registered public companies and large, private companies that meet two of three criteria: revenues above £36 million, a balance sheet above £18 million, or more than 250 employees. A 2026 SECR evaluation by the UK government found measurable energy and emissions reductions attributable to SECR compliance and noted that 47% of compliant businesses reported increased internal awareness.

National Greenhouse and Energy Reporting (NGER)

Australia’s national reporting framework for greenhouse gas emissions, energy production, and consumption operates on a financial-year basis. Reporting must be completed by October 31, with data published by the end of February. Companies report if they exceed certain emissions or energy thresholds—25,000 tonnes of CO2 equivalent at a single facility, or 50,000 tonnes at the corporate level. NGER covered 978 controlling corporations and recorded 296.6 million tonnes of Scope 1 emissions in 2024–25.

Voluntary ESG Frameworks and Standards

Not every company contends with a reporting mandate, but that doesn’t mean ESG frameworks aren’t useful. For example, they can address stakeholder needs that mandatory requirements don’t cover. Many companies also use voluntary frameworks to prepare for future regulations or respond to customer or investor requests. Others use them to share sustainability progress with stakeholders who aren’t yet demanding formal disclosures.

Global Reporting Initiative (GRI)

GRI offers a broad, impact-oriented sustainability reporting system. Its standards help companies of all sizes report economic, environmental, and people impacts. It offers a modular structure; universal standards form the base, and sector and topic standards can be layered on for more specific disclosures. GRI works alongside the IFRS standards to give companies two paths for international reporting—investor-focused and impact-focused.

ISO 26000

ISO 26000, an international standard, offers guidance, not certification, on social responsibility efforts, which can be useful for policy design, governance expectations, stakeholder engagement, and social-responsibility framing. It’s not designed to support detailed ESG reports for investors or regulators.

Sustainability Accounting Standards Board (SASB)

SASB offers industry-based disclosure standards for investor audiences. The standards focus on sustainability-related risks and opportunities that are likely to affect cash flows or the cost of capital. The SASB framework covers 77 industries and is particularly valuable for CFOs and finance-led companies that need to know the metrics that matter for their sector.

Task Force on Climate-related Financial Disclosures (TCFD)

TCFD established the four-pillar structure—governance, strategy, risk management, and metrics/targets—that now underpins most climate disclosure frameworks. While the TCFD name itself still carries recognition, the organization has officially disbanded, having met its remit. Its recommendations have been fully incorporated into the ISSB’s IFRS S2 standard, which means that companies reporting under IFRS S2 automatically meet TCFD requirements.

Climate Disclosure Standards Board (CDSB)

CDSB helped bridge climate disclosure and mainstream financial reporting before being consolidated into the IFRS Foundation in 2022. Although it no longer produces new guidance, its materials remain in the IFRS sustainability archive. Organizations familiar with CDSB can now look to the ISSB standards as its successor.

United Nations Sustainable Development Goals (UN SDGs)

The SDGs are among the best-known sustainability frameworks. They include 17 goals and 169 associated targets under the 2030 Agenda for Sustainable Development. The SDGs don’t provide disclosure standards, but they help companies connect ESG programs to broader goals.

IFRS Sustainability Disclosure Standards

The ISSB standards have become the reference point for global, investor-focused ESG conversations. IFRS S1 introduced overarching requirements for sustainability-related financial disclosures, effective for annual periods beginning on or after January 1, 2024. IFRS S2 established climate-specific disclosure requirements that integrate TCFD recommendations and SASB industry-based guidance. As of 2025, 37 jurisdictions (representing approximately 60% of global GDP) had already decided to use ISSB standards or were taking steps to introduce them.

ESG Rating Agencies

Frameworks tell companies how to report; rating agencies decide how good that reporting looks—and they don’t always agree. Every agency uses its own methodology, so the same company can get different scores from different raters. The scores matter because investors, lenders, and index providers use them to make real decisions—about where to invest, on what terms, and which companies make it into ESG funds.

Familiarity with the following major rating agencies helps companies anticipate how their disclosures will be evaluated and where gaps might affect their scores:

  • Energy Star: Energy Star has become the US industry-standard benchmarking tool for commercial buildings. It is particularly relevant for companies with significant facility footprints. Energy Star Portfolio Manager covers nearly one-quarter of US commercial building space and equates utility and building data to a performance score of 1–100.
  • S&P Global: S&P’s Corporate Sustainability Assessment (CSA) serves as both a benchmark and an input into ESG scores and indexes. In 2025, more than 3,600 companies actively participated in it, while S&P assessed roughly 9,000 more using public information. CSA outputs are key factors in determining eligibility for the Dow Jones Best-in-Class indices.
  • Bloomberg: Bloomberg ESG Scores assess how well companies manage financially material sustainability risks and opportunities. Its methodology comprises more than 30 risk factors and hundreds of data points, covering more than 12,000 companies and using more than 10 years of historical data.
  • Dow Jones Sustainability Index (DJSI): The long-familiar DJSI branding was renamed the Dow Jones Best-in-Class Indices effective February 10, 2025. The indexes track companies that lead their industries in sustainability performance, as measured by S&P Global CSA scores.
  • National Australian Built Environment Ratings System (NABERS): The NABERS building-rating system publicly reports on energy, water, indoor environment quality, and recycling. It’s most relevant for those in real estate and facilities-intensive businesses.

Determining if Your Organization Needs an ESG Framework

Which ESG frameworks matter most depends on who’s asking. A company with EU operations may need to comply with CSRD. One looking for institutional investment will likely encounter questions grounded in IFRS or SASB. 

For midmarket companies, the question often isn’t whether to engage with ESG at all, but which frameworks provide the best return on reporting effort. That’s a calculation that increasingly lands on the CFO’s desk, alongside compliance costs and audit readiness.

A decision tree approach can help determine which frameworks make sense. Is the company regulated? Start with governing requirements. Are there investor/lender expectations? Begin with IFRS/SASB. Is the goal to inform broad stakeholder communication? GRI is likely a good fit. Is the company property-heavy? Then, the GRESB/Energy Star frameworks are appropriate.

Simplify ESG Data Management With NetSuite

Managing ESG reporting across multiple frameworks demands data that often resides in finance, procurement, facilities, HR, and supplier systems. NetSuite ERP connects these functions within a unified cloud platform that replaces the spreadsheet dependence and manual data collection that make sustainability reporting error-prone and difficult to repeat. NetSuite’s built-in AI capabilities add another layer: Anomaly detection flags emissions outliers before they become disclosure problems, narrative reporting tools generate plain-language summaries, and conversational AI lets users query sustainability data without having to chase down reports. For midmarket companies challenged by growing ESG expectations, the combination of unified data and AI-powered analysis can turn sustainability reporting into a repeatable process and a source of strategic insights.

ESG frameworks are more than reporting rules; they’re how companies govern sustainability data. The proliferation of frameworks, standards, benchmarks, and rating systems can seem overwhelming. But the core decision is straightforward: Identify the audiences that matter most—investors, regulators, customers, or all three—and select frameworks that address their needs. From there, build repeatable processes that connect ESG data to the systems running the business. The payoff? Data-driven insights that underlie everything from supply chain management to capital allocation decisions.

ESG Frameworks FAQs

What are the major ESG frameworks?

Major ESG frameworks include the Global Reporting Initiative for broad impact reporting, the Sustainability Accounting Standards Board and International Financial Reporting Standards Sustainability Disclosure Standards (IFRS S1/S2) for investor-focused disclosures, the Corporate Sustainability Reporting Directive and European Sustainability Reporting Standards for European Union regulatory compliance, and the CDP for environmental disclosure programs requested by customers and investors.

What is the best ESG framework?

There is no single “best” ESG framework; the right choice depends on the primary audience and reporting objectives. The International Financial Reporting Standards Sustainability Disclosure Standards (IFRS S1/S2) and Sustainability Accounting Standards Board suit investor-focused reporting; the Global Reporting Initiative supports broad stakeholder communication; the Corporate Sustainability Reporting Directive and European Sustainability Reporting Standards apply where European Union regulations apply; and the Global Real Estate Sustainability Benchmark or CDP may help specific industries or with customer requests.

What is the difference between TCFD and GRI?

The Task Force on Climate-related Financial Disclosures (TCFD) was a climate-focused disclosure architecture organized around governance, strategy, risk management, and metrics for climate-related risks and opportunities. The Global Reporting Initiative (GRI) is a broader, impact-oriented reporting system that covers an organization’s comprehensive effects on the economy, environment, and people.

What is the difference between ESG and TCFD?

ESG is the broad umbrella term covering environmental, social, and governance efforts within an organization. The Task Force on Climate-related Financial Disclosures (TCFD) is a specific climate-disclosure framework within that wider ESG universe, now fully incorporated into the International Sustainability Standards Board's IFRS S2 standard.

What is the difference between TCFD and SASB?

The Task Force on Climate-related Financial Disclosures (TCFD) provides a conceptual framework for organizing climate disclosures, while the Sustainability Accounting Standards Board (SASB) specifies which industry-specific sustainability topics and metrics are likely to be financially material. The two are complementary, and the International Sustainability Standards Board’s IFRS S2 incorporates both the TCFD structure and SASB-derived industry requirements.

What is the difference between GRI and SASB?

The Global Reporting Initiative (GRI) is primarily impact-oriented and designed for broad stakeholder audiences, including employees and communities, while the Sustainability Accounting Standards Board (SASB) is primarily investor-oriented, focusing on sustainability-related risks and opportunities that affect enterprise value. Organizations can use GRI for comprehensive impact reporting and SASB for financially material, industry-specific disclosures.
