Introduction
Financial regulators increasingly require organizations to disclose ESG-related policies, performance and risks. Proactive transparency enables real estate companies to operate ahead of this global trend. Effective public disclosure also facilitates active stakeholder engagement, and empowers investors to make sound investment decisions. GRESB Public Disclosure is unique in its focus to measure material ESG disclosures by REITs and listed property companies.
The evaluation of GRESB Public Disclosure is based upon a set of indicators aligned with the GRESB Real Estate Assessment. This allows for a comparison of ESG disclosure performance between GRESB participants and non-participants. It also provides investors with a resource hub to access ESG disclosure resources across their portfolio.
GRESB Public Disclosure data is initially collected by the GRESB team for selected companies, including both 2019 GRESB Real Estate Assessment participants and non-participants. All constituents have the opportunity to review and update this data before it becomes accessible to GRESB Investor Members. GRESB Public Disclosure consists of four Aspects: Governance of ESG, Implementation, Operational Performance and Stakeholder Engagement. Together, these Aspects contribute towards a Public Disclosure Level, expressed through an A to E sliding scale.
The 2019 results were based on publicly available data from over 650 constituents, of which more than 200 were GRESB participants. The GRESB Public Disclosure dataset covers the major listed real estate indices. The findings highlighted that constituents who participated in the 2019 GRESB Real Estate Assessment scored significantly better in terms of Public Disclosure levels as opposed to their non-participating counterparts. Additionally, Public Disclosure scores appear to be different when comparing the various regions around the globe.
2020 GRESB Public Disclosure Indicators changes
The 22 GRESB Public Disclosure Indicators remain stable at a question level, but introduce additional sub-options to 3 indicators. All new sub-options are aligned with the 2020 GRESB Real Estate Assessment and are intended to offer investors increased insights into the materiality of the disclosed ESG information. In addition, a new indicator on the public commitments to ESG leadership standards and/or principles has been included in the scope of analysis..The stability of the indicators at a question level allows the data to be used for year-over-year comparisons and limits the reporting burden for participants.
About the GRESB Real Estate Assessment
The GRESB Real Estate Assessment is the global standard for ESG benchmarking and reporting for listed property companies, private property funds, developers and investors that invest directly in real estate. The Assessment evaluates performance against three ESG Components - Management, Performance, and Development. The methodology is consistent across different regions, investment vehicles and property types and aligns with international reporting frameworks, such as GRI and PRI.
The GRESB Real Estate Assessment provides investors with actionable information and tools to monitor and manage the ESG risks and opportunities of their investments, and to prepare for increasingly rigorous ESG obligations. Assessment participants receive comparative business intelligence on where they stand against their peers, a roadmap with the actions they can take to improve their ESG performance and a communication platform to engage with investors.
GRESB Public Disclosure data collection
2020 Public Disclosure information is initially collected by GRESB, in the period February 1 through April 1, 2020. The data is then pre-filled in the online GRESB Portal for further review by the relevant listed property company or REIT. GRESB collects publicly disclosed data provided by participants in good faith and does not perform any checks on the quality of this data. It is the responsibility of the constituent to check the accuracy of this data and to update any information that is missing, inaccurate, or out of date.
In light of this product’s mission to promote transparency, all evidence collected by GRESB or provided by constituents will be disclosed to GRESB Investor Members. GRESB collected evidence on a presence/absence basis, recognizing that documentation may be available that better reflects the entity’s ESG efforts. Constituents are therefore encouraged to check and update any data collected and pre-filled by GRESB.
How to update GRESB Public Disclosure data
Step 1: Log into the GRESB Portal

As of April 1st, users new to GRESB need to start by creating a GRESB Portal Account. This can be done free of charge by completing the registration form. Please make sure to sign-up with the email address sent the “Review your 2020 Public Disclosure data email”.Registering with this email address will automatically link your user account to an Assessment with pre-filled Public Disclosure data.
In the registration form, select that you are interested in the GRESB Real Estate Assessment and enter your contact information. Once this step is complete, your public disclosure data will become available for viewing and editing.
People who already have a GRESB user account do not need to create a separate account for GRESB Public Disclosure and can review their data immediately by going to https://portal.gresb.com/log_in and logging into the portal. If you are unsure whether GRESB has collected and pre-filled 2020 Public Disclosure data for your organization, please visit GRESB Helpdesk.
Step 2: Access GRESB Public Disclosure indicators

In 2020, the Public Disclosure Indicators are available separately from the GRESB Real Estate Assessment. GRESB Participants and Public Disclosure constituents for which data has previously been collected, can access the data by first selecting the entity name in the overview section and subsequently selecting “Public Disclosure Indicators”.
Constituents for which Public Disclosure data has not been pre-filled by GRESB can participate in GRESB Public Disclosure, by selecting “Create new Assessment” and subsequently selecting Public Disclosure indicators.
If you are unsure whether GRESB has collected and pre-filled 2020 Public Disclosure data for your organization, please contact GRESB Helpdesk.
Step 3: Review data collected for each indicator

Use the "Contents" button, located in the top-left corner to navigate through each aspect. Constituents should review each Public Disclosure indicator in-depth to assess whether the data collected by the GRESB team is accurate, up-to-date, and complete. If a hyperlink refers to an inaccurate data source, select the discard bin in the evidence field to dissociate the hyperlink from the indicator.
While reviewing the indicators, please note the following:
- GRESB collects data from Annual Reports, CSR/Sustainability Reports, Integrated Reports, and corporate websites, using a presence/absence approach. For the purpose of determining the Public Disclosure level, GRESB does not judge the quality of the information disclosed, nor the ESG performance of the organization, only the level of disclosure. Constituents are advised to provide any missing information.
- All pre-filled data was collected/updated by GRESB from February 1st to April 1st, 2020. More recent data might therefore become available during the reporting period. Constituents are advised to update this data, so that it reflects their most recent ESG disclosures.
- Constituents are advised to update and check any hyperlinks that might have become unresponsive, or that contain potential errors.
Step 4: Submit GRESB Public Disclosure data
Constituents can confirm that their GRESB Public Disclosure dataset is complete. Please note that GRESB maintains the right to use or update any incomplete datasets for scoring purposes.
Step 5: Complete the 2020 GRESB Real Estate Assessment

The 2020 GRESB Public Disclosure information is analyzed and scored separately from the 2020 GRESB Real Estate Assessment, resulting in a Public Disclosure Level. All listed property companies are encouraged to participate in the 2020 GRESB Real Estate Assessment. Please see the 2020 GRESB Real Estate Reference Guide for guidance on completing this Assessment.
Reporting Scope and Boundaries
Public availability
GRESB Public Disclosure consists of a sub-set of indicators from the GRESB Real Estate Assessment, modified for the purpose of measuring levels of ESG disclosure through the following publicly available sources:
- Dedicated sections on company website
- Latest stand-alone CSR/Sustainability Report (including Integrated Reports)
- Sustainability sections within latest Annual Report or Financial Report
All data collected by GRESB for pre-filling was derived from these sources. Constituents may provide publicly disclosed data from other sources, as long as this is a means of official disclosure by the organization (e.g., 10-K filings or PRI Reports). Information disclosed through public channels, such as twitter or personal blogs, is not deemed an official disclosure by the organization.
Material that is disclosed through internal channels (e.g., email, presentations, internal websites), or that requires any form of (online) registration to access, is not deemed “publicly available”.
Reporting scope
All evidence needs to relate directly to the investable entity, i.e. the listed / public company. In case the day-to-day management responsibilities of the listed company are outsourced to a third-party investment manager, ensure that the text box below the evidence field includes a clear description of how this is applicable to the entity. Evidence will not be accepted without a clear explanation.
Reporting period
GRESB Public Disclosure assesses an entity's most recent ESG disclosures efforts. Constituents are encouraged to update any pre-filled evidence, so that it reflects their most recent ESG disclosures. Data provided through an Annual Report or stand-alone Sustainability Report, as well as operational consumption data (e.g., energy, water, GHG, waste), must as a minimum relate to the entity’s 2018 reporting year (calendar or fiscal). Employee and tenant satisfaction surveys must as a minimum have been undertaken in the past three years.
Language
Preliminary data collected by the GRESB team focusses on documentation disclosed in English. Constituents may provide additional evidence in the form of hyperlinks to web pages or documents in languages other than English. However, this needs to be accompanied by an English description of the evidence’s content in the text box underneath the evidence field. Without a clear English description, the evidence will not be accepted.
Location of relevant information
In order to facilitate the data validation process, constituents should use the assigned text box to indicate where in the web page or online document the relevant information can be found. Participants should ensure that the relevant page can be accessed within two steps. A description of these steps needs to be provided in the text box underneath the hyperlink field.
The constituent has the obligation to ensure that the hyperlink is functioning. Broken links are the responsibility of the constituent and will be interpreted as the absence of evidence.
Timeline and process
Initial data collection by GRESB (February 1 - April 1, 2020)
GRESB checked and updated the information included in GRESB Public Disclosure 2019 and collected information for additional constituents in the period February 1 and April 1, 2020.
Data review by constituents (April 1 - July 1, 2020)
GRESB Public Disclosure 2020 will be open for review starting April 1 through July 1, 2020, in parallel to the 2020 GRESB Real Estate Assessment. During this period, listed property companies and REITs can review their pre-filled Public Disclosure data collected by GRESB and in tandem complete the 2020 GRESB Real Estate Assessment.
Data validation by GRESB (July - September, 2020)
All data provided, updated, or amended by GRESB Public Disclosure constituents will be checked and validated using the GRESB Validation Portal by GRESB and its parent company, GBCI, based upon the reporting rcope and boundaries, definitions and Interpretations, described in this document, in the period July - September, 2020.
During this period, GRESB maintains the right to expand on the 2020 GRESB Public Disclosure Constituent universe, by collecting data on additional listed property companies and REITs.
Launch of Public Disclosure results (September 4, 2020)
The 2020 GRESB Public Disclosure results will be made available to the listed companies included in the analysis, as well as to GRESB Investor Members, in the first week of September, 2020. The results will be released in parallel with the 2020 preliminary GRESB Real Estate Assessment results.
Scoring and analysis
The 2020 GRESB Public Disclosure information includes 23 indicators, covering four Aspects. Each indicator is scored between zero and full points, depending on the availability of evidence and selected answer options. Combined, these indicators add up to a maximum of 70 points. Constituents receive a GRESB Public Disclosure Level, from A to E, based on the following scale:
GRESB Public Disclosure Level |
Number of points received |
A |
57 - 70 |
B |
43 - 56 |
C |
29 - 42 |
D |
15 - 28 |
E |
0 - 14 |
Data provided, updated, or amended by GRESB Public Disclosure constituents will be validated.

GRESB an entity’s Public Disclosure Level into context by assigning it to a comparison group based on country/region, property sector, and market value. Note that an entity’s Public Disclosure comparison group differs from the GRESB Real Estate Assessment Peer Group.
Who can see my data?
The 2020 GRESB Public Disclosure results will be made available via the GRESB Portal to GRESB Investor Members in September 2020. The results will be disclosed together with the evidence collected by GRESB and provided by the constituents.
GRESB Investor Members with a listed data subscription are able to view the Public Disclosure level and supporting information for all entities.
