SASB for Manufacturing

What is SASB?

The Sustainability Accounting Standards Board (SASB) is an independent nonprofit organization that develops industry-specific sustainability accounting standards designed to help businesses disclose financially material environmental, social, and governance (ESG) information to investors. Founded in 2011 and now operating under the umbrella of the IFRS Foundation alongside the International Sustainability Standards Board (ISSB), SASB provides a structured framework that connects sustainability performance to financial outcomes. Unlike broad ESG frameworks, SASB standards are granular, sector-specific, and built around the principle that different industries face different sustainability risks and opportunities.

SASB and the Manufacturing Industry

Manufacturing sits at the intersection of nearly every material sustainability issue that SASB standards address. Factories consume vast quantities of energy and water, generate significant waste streams, rely on complex global supply chains, and employ large workforces subject to occupational health and safety risks. Because these operational realities translate directly into financial exposure — through regulatory fines, energy costs, supply chain disruptions, and reputational damage — SASB treats manufacturing disclosures as financially material, not merely aspirational.

SASB does not treat "manufacturing" as a single monolithic category. Instead, it has developed separate standards for subsectors including Industrial Machinery and Goods, Chemicals, Electronic Manufacturing Services and Original Design Manufacturing, and Apparel and Accessories. A heavy equipment manufacturer, for example, faces different material topics than a contract electronics assembler. The machinery producer must account for product lifecycle impacts and hazardous materials in end-of-life disposal, while the electronics assembler must address conflict minerals sourcing and labor conditions in its supplier factories.

Concrete examples make this relevance clear. An automotive parts manufacturer disclosing under SASB standards would need to quantify its greenhouse gas emissions from paint booths and heat treatment processes, report water withdrawal volumes at facilities located in water-stressed regions, and disclose the percentage of its product revenue derived from fuel-efficient or alternative energy components. A chemical manufacturer, meanwhile, would need to report Tier I and Tier II process safety incidents, the total weight of hazardous waste generated, and management approaches to air emissions of volatile organic compounds. These are not abstract metrics — they are the numbers that determine insurance premiums, facility permitting outcomes, and long-term operating license from local communities.

Key Requirements

While specific metrics vary by subsector, manufacturing companies reporting under SASB standards are generally expected to address the following material topics:

• Greenhouse Gas Emissions: Disclosure of Scope 1 (direct) and Scope 2 (purchased energy) greenhouse gas emissions in metric tons of CO2 equivalent, along with a description of long-term and short-term emissions reduction strategies and targets.
• Energy Management: Reporting of total energy consumed, percentage from grid electricity, and percentage from renewable sources. Manufacturers with energy-intensive processes such as smelting, forging, or continuous kilning face heightened scrutiny on this metric.
• Water and Wastewater Management: Total water withdrawn and consumed, with a breakdown of sources and the percentage withdrawn in regions with High or Extremely High Baseline Water Stress as defined by the World Resources Institute Aqueduct tool.
• Waste and Hazardous Materials Management: Total weight of hazardous and non-hazardous waste generated, the percentage sent to landfill versus recycled or incinerated with energy recovery, and the number of reportable spills or releases to the environment.
• Product Safety and Quality: For manufacturers of goods that reach consumers or downstream industrial users, SASB requires disclosure of recalls, product liability claims, and quality management system certifications such as ISO 9001.
• Supply Chain Management: Disclosure of practices used to assess and manage environmental and social risks within the supply chain, including audits of tier-one suppliers and the percentage of suppliers meeting defined sustainability criteria.
• Workforce Health and Safety: Total recordable incident rate (TRIR), fatality rate, and near-miss frequency, along with descriptions of safety management system standards adopted (for example, ISO 45001).
• Labor Practices: Percentage of employees covered by collective bargaining agreements, employee turnover rates, and average hours of training per employee per year, particularly relevant for labor-intensive assembly operations.
• Responsible Sourcing of Materials: For manufacturers using materials such as tin, tantalum, tungsten, or gold, disclosure of the due diligence process used to identify and manage conflict minerals risks in the supply chain, consistent with OECD guidance.

Implementation Steps for Manufacturing Companies

1. Identify the applicable SASB standard for your subsector. Visit the SASB Standards Navigator at sasb.org and locate the standard corresponding to your primary industrial classification. A company producing hydraulic systems for construction equipment would fall under Industrial Machinery and Goods, while a contract manufacturer producing printed circuit boards would reference the Electronic Manufacturing Services and Original Design Manufacturing standard. Download the full standard document, which includes the complete list of disclosure topics, accounting metrics, and technical protocols.
2. Conduct a materiality assessment. Not every topic in a SASB standard will be equally material to every company. Convene a cross-functional working group — including finance, operations, environmental health and safety, legal, and investor relations — to evaluate which sustainability topics present the greatest financial risk or opportunity for your specific business model, geographic footprint, and customer base. Document the rationale for any topics considered immaterial and excluded from reporting.
3. Audit existing data collection systems. Map each SASB metric against your current data sources. Energy consumption data may already exist in utility billing systems or energy management software. Safety incident data typically resides in an EHS management platform. Water withdrawal data may require new metering at facilities located in water-stressed areas. Identify gaps between what SASB requires and what you currently capture, and build a data gap closure plan with ownership assignments and deadlines.
4. Establish data governance and internal controls. Sustainability data submitted to investors must meet the same accuracy standards as financial data. Assign clear data owners at the facility level, define calculation methodologies in writing (for example, specifying the emission factors used to convert kilowatt-hours of electricity into CO2 equivalent), implement review and approval workflows, and retain supporting documentation for at least five years in case of external audit or investor inquiry.
5. Engage your supply chain. If supplier practices are material to your SASB disclosure — as they are for conflict minerals, labor standards, or purchased goods emissions — begin supplier engagement early. Develop a supplier code of conduct aligned with SASB expectations, distribute self-assessment questionnaires, and prioritize on-site audits for high-risk or high-spend suppliers in geographies with elevated environmental or labor risk profiles.
6. Draft and internally review disclosures. Write the narrative descriptions and populate the quantitative metrics called for by your applicable SASB standard. Have the draft reviewed by legal counsel for accuracy and completeness, by finance for consistency with financial statement disclosures, and by senior leadership for strategic alignment. Identify claims that require external verification and budget accordingly.
7. Obtain third-party assurance. While SASB does not mandate external assurance, investors increasingly expect at least limited assurance on key environmental metrics such as greenhouse gas emissions and water withdrawal. Engage an accredited assurance provider — typically a major accounting firm or specialized sustainability assurance firm — early enough in the reporting cycle to allow time for their procedures without compressing your publication timeline.
8. Publish and communicate your SASB disclosure. SASB disclosures can be incorporated into an annual report, a standalone sustainability or ESG report, or regulatory filings such as an SEC Form 10-K (where financially material). Use the SASB Standards Index format to clearly cross-reference each metric and disclosure topic, making it easy for investors and analysts to locate and compare your data.

Frequently Asked Questions

Is SASB reporting mandatory for manufacturing companies?

SASB reporting is voluntary in most jurisdictions, but the practical pressure to comply is growing rapidly. In the United States, the Securities and Exchange Commission's climate disclosure rules reference SASB-aligned metrics. In the European Union, the Corporate Sustainability Reporting Directive (CSRD) requires large companies to disclose sustainability information that substantially overlaps with SASB topics. Many large institutional investors, including BlackRock, Vanguard, and State Street, formally request SASB-aligned disclosures from portfolio companies as part of their stewardship programs. Manufacturers that sell to large original equipment manufacturers or participate in public procurement processes increasingly face SASB reporting as a contractual prerequisite.

How does SASB differ from GRI, CDP, or the TCFD framework?

The Global Reporting Initiative (GRI) is designed for broad stakeholder communication and covers a wide range of social and environmental impacts regardless of financial materiality. CDP collects climate, water, and forest data primarily for supply chain transparency purposes. The Task Force on Climate-related Financial Disclosures (TCFD) provides a qualitative governance and risk management framework for climate specifically. SASB occupies a distinct niche: it is designed for investor-focused disclosure of financially material sustainability information, organized by industry sector. In practice, many manufacturers use SASB alongside GRI and TCFD, treating them as complementary rather than competing frameworks. The ISSB's IFRS S1 and S2 standards, now globally adopted in several jurisdictions, incorporate SASB industry metrics as the primary vehicle for sector-specific disclosure.

What resources are available to help a mid-sized manufacturer get started with SASB?

SASB publishes all of its standards for free at sasb.org, including the full text of each industry standard, technical protocols defining calculation methodologies, and implementation guidance documents. The SASB Standards Navigator tool allows users to browse standards by industry and download comparison tables. The Value Reporting Foundation (now integrated into the IFRS Foundation) also published a suite of implementation primers. For manufacturers seeking peer benchmarks, the Bloomberg Terminal, Refinitiv Eikon, and MSCI ESG databases aggregate SASB-aligned disclosures from public companies, enabling comparison against sector peers. Industry associations such as the National Association of Manufacturers have also begun publishing guidance on SASB adoption for their membership.

How long does it typically take a manufacturing company to implement SASB reporting for the first time?

For a company starting from minimal ESG data infrastructure, a first full SASB disclosure typically requires eight to twelve months of preparation. The most time-consuming elements are closing data gaps — particularly installing meters for water and energy at individual facilities, implementing supplier assessment programs, and establishing internal review and approval controls. Companies that already maintain ISO 14001 environmental management systems or ISO 45001 occupational health and safety systems have a significant head start, because those systems already generate much of the underlying operational data that SASB metrics require. Subsequent reporting cycles typically require two to three months, as systems and processes are already in place.

Summary

SASB provides manufacturing companies with a rigorous, investor-grade framework for communicating the sustainability risks and opportunities that are most likely to affect long-term financial performance — from energy costs and water availability to supply chain resilience and workforce safety. The standards are specific enough to be actionable and flexible enough to accommodate the genuine diversity of business models within the manufacturing sector. Companies that begin building the data infrastructure, governance processes, and stakeholder engagement programs required for SASB compliance today will be better positioned to meet growing regulatory requirements, satisfy institutional investor expectations, and demonstrate the operational discipline that distinguishes durable manufacturers from their peers.
