SASB

Sustainability Accounting Standards Board

Industry-specific ESG metrics for financial decision-making

Launched

2011

Governed by

IFRS Foundation (following 2022 consolidation with ISSB)

Audience

Financial investors, securities analysts, corporate investor relations

Mandatory

Voluntary

Report Format

Standardised quantitative metrics aligned to industry-specific standards

Update Cycle

77 industry standards published; now being integrated into ISSB sector guidance

Not legally mandatory; referenced by SEC disclosure guidance, CSRD, and many institutional investor RFPs

Overview

SASB Standards identify the subset of ESG issues most likely to be financially material for companies in 77 specific industries across 11 sectors. Unlike GRI's comprehensive impact coverage, SASB is deliberately narrow — it focuses only on topics with evidence of investor relevance, and it quantifies those topics in industry-specific, comparable metrics.

Why It Matters for ESG Analysis

SASB is the ESG data standard most valued by equity analysts and portfolio managers because it produces directly comparable, industry-specific metrics. A SASB disclosure allows investors to benchmark a company's data privacy practices against every other internet media company, or compare an oil company's spill rates against its upstream peers. This comparability makes SASB-aligned data the most useful for ESG factor construction in quant strategies.

Key Requirements

Industry identification

required

Select the correct SASB industry standard from 77 options across 11 sectors

Activity metric disclosure

required

Report the activity metrics (e.g., revenue, production volume) that contextualise ESG metrics

Accounting metrics

required

Report the quantitative ESG metrics specified for the industry (typically 10–20 metrics)

Technical protocol

recommended

Follow the calculation methodology in the industry Technical Protocol for each metric

Assurance

optional

External assurance increases credibility but is not required by the standard

The 11-sector, 77-industry structure

SASB organises industries into 11 sectors: Technology & Communications, Health Care, Financials, Consumer Discretionary, Consumer Staples, Food & Beverage, Resource Transformation, Extractives & Minerals Processing, Infrastructure, Transportation, and Services. Within each sector, SASB identifies industry-specific standards. For example, the Software & IT Services standard focuses on data privacy and security, whereas the Electric Utilities standard focuses on greenhouse gas emissions and grid reliability.

Financially material vs. comprehensive

SASB's intentional narrowness is both its strength and its limitation. Because SASB only covers financially material topics per industry, a SASB report for a consumer products company will not cover community engagement, indigenous rights, or biodiversity — even if those topics are significant for affected stakeholders. Companies using SASB alone cannot claim comprehensive ESG disclosure. The combination of SASB (for financial materiality) and GRI (for impact materiality) is the dominant approach for large listed companies.

  • Average SASB standard covers 13 industry-specific metrics
  • Most metrics are quantitative (not narrative), enabling year-on-year comparison
  • SASB metrics are aligned to the concepts in IFRS S2 climate disclosures

Integration with ISSB

Since the consolidation of SASB under the IFRS Foundation in 2022, SASB Standards are being progressively integrated into ISSB's work programme. IFRS S1 explicitly states that companies can use SASB Standards to identify what sustainability information is relevant to their industry. Future ISSB sector-specific guidance is expected to draw heavily from SASB methodology.

How OpenESG scores against SASB

For each company, OpenESG identifies the most relevant SASB industry standard and evaluates disclosure against the required accounting metrics. We assess whether each metric is fully disclosed, partially disclosed, referenced but not quantified, or not disclosed. The SASB alignment score reflects the proportion of industry-relevant metrics for which investable-quality data is publicly available.

Common Misconceptions

SASB does not set environmental targets — it sets disclosure requirements. A company can score well on SASB by disclosing high emissions clearly.

SASB is not the same as ESG performance — it measures disclosure of financially material ESG information, not the underlying sustainability performance.

SASB standards are not comparable across industries by design — a 70/100 SASB score in software is measuring completely different things than a 70/100 score in oil & gas.

How OpenESG Scores SASB

OpenESG maps each of the 21 companies in our universe to their primary SASB industry standard and evaluates disclosure completeness against the required accounting metrics. Industry-specific ratings reflect what proportion of financially material ESG data is publicly accessible for each company.
