SASB Real Estate

1. Download the Standard: Access the SASB Real Estate Services Standard (IF0403) for free at sasb.org. Review the full standard to understand the disclosure topics and accounting metrics specific to the real estate sector.

1. Conduct a Materiality Assessment: Identify which of the SASB-defined sustainability topics are most material to your organization's operations — typically energy management, water management, GHG emissions, and tenant engagement.

1. Assemble Your Reporting Team: Bring together sustainability, finance, operations, and investor relations staff. Assign ownership of each metric to the team members with access to the relevant data.

1. Collect and Validate Data: Gather quantitative data for each required metric — energy consumption (MWh), water withdrawal (thousand cubic meters), Scope 1 and 2 GHG emissions (MT CO2e), percentage of ENERGY STAR certified properties, and indoor air quality indicators.

1. Map to Your Existing Reporting: Align SASB disclosures with any existing GRI, TCFD, or IFRS S1/S2 reporting your organization already produces to avoid duplication and maximize efficiency.

1. Draft and Review Disclosures: Prepare the SASB-aligned disclosures in your sustainability report, annual report, or a standalone ESG report. Ensure qualitative discussion accompanies quantitative metrics.

1. Consider Third-Party Assurance: Optionally engage an external auditor for limited or reasonable assurance on your SASB disclosures to enhance credibility with investors.

1. Publish and Communicate: Publish your disclosures and notify investors and stakeholders. Consider registering your disclosure on the IFRS Foundation's reporting database and communicating adoption through investor relations channels.

The SASB Real Estate Services Standard (IF0403) defines disclosure topics and associated accounting metrics across several material sustainability dimensions. Organizations are expected to report quantitative and qualitative data against each topic.

Energy Management: Organizations disclose total energy consumed (MWh), percentage from grid electricity, and percentage from renewable sources. The standard also calls for disclosure of the percentage of properties with an ENERGY STAR certification or equivalent energy rating, reflecting operational efficiency across the portfolio.

Water Management: Disclosures cover total water withdrawn (thousand cubic meters) and the percentage of properties in water-stressed regions. This metric is particularly material for large commercial portfolios in arid or water-scarce geographies.

Management of Tenant Sustainability Impacts: This topic addresses how real estate companies engage tenants on sustainability performance. Metrics include the percentage of new leases that include green lease clauses and the percentage of tenants covered by sustainability-related lease agreements, reflecting the landlord-tenant dynamic in driving building-level performance.

Climate Change Adaptation: Organizations describe their approach to identifying and managing physical climate risks across their portfolio. This is a qualitative disclosure covering risk assessment methodologies, resilience strategies, and capital planning for climate-exposed assets — closely aligned with TCFD recommendations.

Indoor Air Quality (where applicable): For certain property types, organizations may disclose policies and performance data related to indoor environmental quality, including ventilation standards and air quality monitoring.

There is no scoring, weighting, or pass/fail threshold — organizations self-report against these topics and metrics, and the quality and completeness of disclosure is evaluated by investors and analysts rather than by SASB itself.

The SASB Real Estate Services Standard is one of the most widely referenced ESG disclosure frameworks in the institutional real estate sector. Since SASB's integration into the IFRS Foundation in 2022 and the subsequent development of IFRS S1 and S2 sustainability disclosure standards, SASB's industry-specific metrics have been formally embedded as the recommended disclosure vocabulary for IFRS-aligned reporting. This has significantly elevated SASB's global standing, particularly in markets where IFRS adoption is mandatory or strongly encouraged.

In North America, SASB standards are heavily used by publicly traded REITs and large institutional asset managers. Organizations such as Prologis, CBRE, JLL, and Brookfield regularly reference SASB in their sustainability reports. The framework is also widely used by ESG data providers — including MSCI, Sustainalytics, and Bloomberg — as a structured input for ESG ratings and analytics. GRESB, the dominant real estate-specific ESG benchmark, accepts SASB-aligned disclosures as supporting evidence, further reinforcing adoption.

Globally, adoption is growing but uneven. European real estate firms tend to prioritize GRI and EU CSRD-aligned reporting, though SASB is increasingly used in parallel. In Asia-Pacific, adoption is accelerating as institutional investors demand standardized ESG data. The primary competitive dynamic is not between SASB and other certifications per se, but between SASB and other reporting frameworks (GRI, TCFD, CDP). SASB's key differentiator is its industry-specific, investor-focused materiality approach — it tells companies exactly what to report for their sector, rather than offering a broad menu of optional disclosures. Demand for SASB-fluent professionals and SASB-aligned reporting is expected to grow as IFRS S1/S2 adoption expands globally.

The Sustainability Accounting Standards Board (SASB) was founded in 2011 by Jean Rogers in San Francisco, with a mission to develop industry-specific sustainability accounting standards that help businesses disclose financially material ESG information to investors. Modeled loosely on the Financial Accounting Standards Board (FASB), SASB sought to bring the same rigor and comparability to sustainability reporting that GAAP brought to financial reporting. The organization spent its first several years conducting extensive industry research and stakeholder consultation to identify which sustainability topics were most likely to be financially material for each of 77 industries.

The Real Estate Services Standard (IF0403) was developed as part of SASB's Financials sector standards, covering real estate services companies. SASB published its full suite of 77 industry standards in November 2018 following years of provisional standards and public comment periods. A major milestone came in 2022 when the IFRS Foundation — the body that oversees International Financial Reporting Standards — consolidated SASB into its newly formed International Sustainability Standards Board (ISSB). The ISSB subsequently published IFRS S1 and S2 in 2023, formally incorporating SASB's industry-specific metrics as the recommended disclosure framework. This integration effectively elevated SASB standards from a voluntary best-practice framework to a foundational component of the emerging global baseline for sustainability disclosure.
