SASB Standards: Industry-Specific ESG Materiality Metrics

Key Takeaways

• SASB standards cover 77 industries across 11 sectors under the SICS classification, each providing a short list of financially material disclosure topics with specific quantitative metrics and technical protocols.
• IFRS S1 explicitly requires companies to consider SASB standards when identifying sustainability risks and opportunities, and IFRS S2 incorporates SASB's industry-based climate metrics directly.
• A common investor mistake is treating SASB as a standalone framework that satisfies EU CSRD or CDP requirements, SASB covers only financial materiality, while CSRD also requires impact materiality and GRI covers stakeholder reporting.
• A water utility and a software firm face nearly zero overlapping material SASB topics, demonstrating that generic ESG questionnaires applied uniformly will hide material signals for both.

What It Is

The Sustainability Accounting Standards Board was founded in the United States in 2011. It published a full set of industry standards in 2018 under the Sustainable Industry Classification System (SICS), which splits the economy into 77 industries across 11 sectors. Each industry standard lists the disclosure topics that are financially material for that industry, with quantitative metrics and technical protocols.

SASB was consolidated with the IIRC in 2021 to form the Value Reporting Foundation, which merged into the IFRS Foundation in 2022. The International Sustainability Standards Board now holds and evolves the standards. In July 2025 the ISSB launched a comprehensive review of priority SASB Standards.

The Intuition

Generic ESG questionnaires ask every company the same thing. Many of those questions do not matter to every business. A water utility and a software platform face very different sustainability risks, and treating them with the same scorecard hides both the important signal and the unimportant noise.

SASB starts from the opposite direction. For each industry it asks a narrow question: which sustainability issues are reasonably likely to affect the financial condition or operating performance of a typical company, and how should those issues be measured? The output is a short list of disclosure topics and metrics.

How It Works

Each SASB standard follows the same structure. Disclosure topics sit at the top, each with a plain description of why the topic is financially material for that industry. Accounting metrics provide the specific quantitative measures, such as tonnes of CO2e per unit produced or the percentage of employees in high consequence fatality roles. Activity metrics provide context variables, such as units produced, that let users normalise the accounting metrics.

Materiality in SASB is financial materiality. A topic is included in a standard if there is credible evidence that it can affect enterprise value through revenue, costs, assets and liabilities, or cost of capital. The SASB Materiality Map summarises which topics are flagged as likely material across industries, a useful first screen when comparing across peer groups.

ISSB integration added a formal hook. IFRS S1 requires preparers to consider the SASB Standards when identifying sustainability-related risks and opportunities and when choosing disclosures beyond those specified in an ISSB standard. IFRS S2 on climate includes industry-based disclosure requirements drawn from SASB's climate metrics, so SASB-aligned reporting feeds directly into IFRS S2.

Worked Example

A midstream oil and gas company applies the SASB standard for Oil and Gas Midstream (EM-MD). The standard identifies five disclosure topics as financially material: greenhouse gas emissions, ecological impacts, competitive behaviour, critical incident risk management, and operational safety, emergency preparedness, and response.

For greenhouse gas emissions, the company reports EM-MD-110a.1 gross global Scope 1 emissions of 3.2 million tCO2e, the percentage covered under emissions-limiting regulations at 74 percent, and methane emissions at 45 percent of total Scope 1. Under EM-MD-540a.1 it reports three loss of primary containment events above 1 barrel in the year and describes the root cause for each. Activity metrics include total pipeline throughput, which users apply to compute intensity ratios.

Compare this with a retail bank applying FN-CB Commercial Banks. The financially material topics there are data security, financial inclusion and capacity building, and incorporation of ESG factors in credit analysis. The overlap with the midstream operator is almost zero. That divergence is the point of the framework.

Common Mistakes

1. Cherry picking metrics across industries. A company in multiple businesses must apply each SASB standard that fits a material part of its operations, not pick the easiest metrics from adjacent standards.
2. Skipping activity metrics. Reporting only the accounting metric without the activity base (tonnes produced, revenue, customer count) leaves users unable to compute intensity, which is usually what they care about.
3. Treating SASB as a replacement for CSRD or CDP. SASB supplies industry metrics that fit into broader reporting. It is not a standalone framework that satisfies EU regulation, and it does not cover impact materiality.
4. Ignoring the ISSB update cycle. Because SASB is now inside the IFRS Foundation, metrics change through ISSB due process. Reporters that freeze on the 2018 text miss subsequent updates and the targeted amendments now in progress.
5. Confusing financial materiality with indifference to impact. SASB's narrow lens is by design. Users who need impact materiality for regulatory reasons should add CSRD or GRI, not stretch SASB beyond its scope.

Frequently Asked Questions

Q: What are SASB standards in simple terms? SASB standards are a set of industry-specific checklists identifying which sustainability issues are financially material for each of 77 industries, covering the metrics that actually affect revenue, costs, assets, or cost of capital for that specific business type, rather than asking every company the same generic questions.

Q: How do SASB standards affect investment decisions? They help analysts compare companies within the same industry on the metrics that matter most, methane intensity for oil and gas, cybersecurity incidents for financial services, water-use intensity for semiconductors. A peer comparison using the right SASB industry metrics is far more informative than a generic ESG score.

Q: What is a real-world example of SASB standards in practice? A midstream oil-and-gas company applies the SASB EM-MD standard and reports 3.2 million tCO2e Scope 1 emissions (45% of which is methane), 74% regulatory coverage, and three loss-of-containment incidents with root-cause analysis, metrics that are immediately comparable to peers and feed into IFRS S2 industry-based disclosures.

Q: How can investors use SASB standards to improve ESG analysis? Use the SASB Materiality Map as a first screen: it shows which topics are flagged as likely material across industries. When comparing companies in the same peer group, check whether they use the same SASB industry standard and whether they report activity metrics (production volume, revenue) so accounting metrics can be normalized.

Q: How are SASB standards different from GRI standards? SASB focuses on financial materiality, issues that affect enterprise value from an investor perspective. GRI focuses on stakeholder materiality, impacts that matter to employees, communities, and civil society, regardless of financial effect. The two frameworks are complementary; companies needing to satisfy both investors (SASB/ISSB) and regulators (CSRD/GRI) typically use both.
