External review
Has the data reported been reviewed by an independent third party?

Assessment Instructions
Intent: What is the purpose of this indicator?
The intent of this indicator is to assess health and safety performance associated with the entity’s employees. The health and safety of employees is a common key performance indicator for infrastructure operators.
Input: How do I complete this indicator?
Select Yes or No: If ‘Yes,’ complete the performance table and sub-questions.
Performance Tables
Cells with a dark green border are mandatory.
Cells with a light green shade are scored. Not all scored cells are mandatory. Leaving a scored (i.e., shaded) cell blank will have negative scoring impacts. ‘Zero’ is an acceptable answer if it is true and accurate (i.e., if no target exists, the cell should be left blank).
Data
Instructions
Performance: Previous Year
It is not possible to edit any data in this column.
As previous-year data is directly drawn from the previous year's Asset Assessment, it is not possible to amend erroneous data. If the previous-year data is incorrect (for example, due to a reporting error), the entity can use the open text box below the indicator to inform investors. This column shows the reported performance for the previous year (e.g., calendar year 2024). If a metric is new or has changed substantially compared to last year’s assessment, or if there is no data available for the entity for the previous year, it is indicated as ‘N/A'.
Performance: Reporting Year
Enter data for performance during the reporting year for each metric.
Scored and mandatory: Reporting year performance of: 'Lost time injuries' and 'Total recordable injuries'.
See definitions for each metric in the Terminology section below.
Target: Reporting Year
Enter any targets that were applicable for the reporting year for each metric.
Scored but not mandatory: Reporting year target of: 'Lost time injuries' and 'Total recordable injuries'.
A reporting year target can be interpolated from a future-year target. The target (or the future-year target from which it is derived) must be formally adopted. This means that the entity must have set and communicated the target, at least internally, and implemented or is preparing actions to achieve it.
Target: Future Year
Enter the relevant year for which the targets are set at the top of the column, and enter the future-year targets for each metric where available.
Scored but not mandatory: Future year target of: 'Lost time injuries' and 'Total recordable injuries'.
The target must be set for any future year that is not the reporting year. The target (or the future-year target from which it is derived) must be formally adopted. This means that the entity must have set and communicated the target, at least internally, and implemented or is preparing actions to achieve it.
Data Coverage: Reporting Year Performance
Insert a data coverage level from 0% to 100% in single-digit increments for each metric where required. Scored and mandatory: Reporting year performance Data Coverage (%) of: 'Lost time injuries' and 'Total recordable injuries'.
Data coverage for any individual performance metric should represent an estimated percentage considering all material data related to all facilities and activities within the entity’s reporting boundary (RC3 and RC4) for the full reporting year. Facility Exclusions: Facilities within an asset that have the following characteristics can be excluded in the reported data coverage levels:
Facilities under development.
Facilities that the asset has owned for less than 6 months.
Facilities that have been operational for less than 6 months.
Therefore, an asset can still report up to 100% data coverage for facilities even if it does not report data from facilities in the three categories noted above.
Note that if an asset reports less than 100% data coverage, its Benchmark Report will not display reporting-year performance data intensity values.
Data Coverage: Calculation Methodology
Provide a description of the method used to calculate data coverage in the open text box below the performance tables. Not scored but mandatory: Data coverage methodology In an open text box, describe the method used to calculate data coverage, including how the data was measured and how the coverage level was estimated or assessed (e.g., % coverage of facilities, output, GAV, or any other metric used).
Intensities
It is not possible to edit any data in this section. GRESB automatically calculates intensity metrics based on data reported to other indicators.
Estimation Note
As a general rule, GRESB Participants are required to use actual data (i.e., directly measured from utilities or meters, documented, or derived using recognized standards) when reporting material performance data.
Broad extrapolations of data and general estimates should not be reported.
Participants must explain the methodology used to measure data and to calculate data coverage in an open text box below the performance table.
External Review
Select Yes or No: If selecting “Yes”, state whether the data submitted has been checked, verified, or assured (select one option; the most detailed level of scrutiny to which the data was subjected). If selecting ‘verified’ or ‘assured,’ select the standard from the dropdown menu.
The Scheme Lists page contains the complete list of accepted assurance and verification schemes.
Additional assurance schemes may also receive recognition if they meet GRESB’s criteria. To submit a new scheme for review, please contact the GRESB team.
The final deadline for submitting a new assurance/verification scheme for review by the GRESB team is March 15th. Schemes submitted for review after March 15th will not be reviewed until the subsequent reporting year.
GRESB does not require the selected standard to be specific to health and safety data. As such, a standard initially designed to verify/assure other types of sustainability data can be selected as long as the same thoroughness and review criteria are applied to data reported in HS1.
Terminology
Data coverage
The part of the asset for which data is available. Data coverage for any individual performance metric should represent an estimated percentage considering all material data related to all facilities and activities within the entity’s reporting boundary (RC3 and RC4) for the full reporting year.
Employee
Someone who works directly for the asset and receives compensation in the form of an hourly wage or annual salary for their work. This can be both onsite or offsite (such as in an administration office). Employers typically have to pay specific benefits such as contributions to pensions or taxes for employees. Employees may be either full time or part time and may operate on a short term contract.
Externally checked
Applies to instances when a third party has reviewed the data in a structured and consistent process, but no official certification has been awarded.
Externally verified
Applies to instances where a third party has reviewed the reporting against an existing scheme. When this checkbox is ticked, participants must select the scheme name from the dropdown.
Note that GRESB treats verification and assurance equally in the context of the assessment
Externally assured
Applies to instances where a third party has reviewed the data against an existing scheme. When this checkbox is ticked, participants should select the scheme name from the dropdown.
Note that GRESB treats verification and assurance equally in the context of the assessment
Fatality
The death occurring in the current reporting period, arising from an injury or disease sustained or contracted.
Health and safety
Protecting the entity's stakeholders from harm or death due to injury or disease. Often, this is executed by developing policy, analyzing and controlling health and safety risks, providing training, and recording and investigating health and safety incidents.
Hours worked
The total number of hours worked by the workers in the entity, either employees or contractors, expressed in actual total hours. For example, a worker under a 40-hour contract working for four weeks has worked 160 hours in total.
Lost Time Injury
Any injury, arising in the course of work, that results in temporary or permanent time away from work. Includes fatalities, permanent disabilities and injuries that have led to absence from work.
Lost Time Injury Frequency Rate (LTIFR)
The number of lost time injuries occurring in a workplace per million hours worked.
Lost time injuries / Total hours worked X 1,000,000
Near-miss incident
An incident that had the potential to result in injury, but where in no injury was sustained.
Recordable injury
An injury arising that requires medical treatment beyond first aid, as well as one that causes death, days away from work, restricted work or transfer to another job, or loss of consciousness.
Total Recordable Injury Frequency Rate (TRIFR)
The number of incidents per 100 full-time workers. To calculate TRIFR use the following formula:
Total recordable injuries / Total number of hours worked X 1,000,000
Validation: What evidence is required?
Data: GRESB automatically validates data in the performance tables.
Evidence: Providing evidence of external review in the form of a third-party letter or certificate is optional. Evidence will not be subject to manual validation for this indicator in 2025.
Evidence should include:
Proof of the existence of a third-party review of the data;
Clear indication that the reviewed data reflects the reported data;
A description of the type of third-party review (checked, verified, or assured) and the used assurance standard (if applicable);
Proof that the data review applies to the entity.
Scoring
Scoring: How does GRESB score this indicator?
Materiality-Based Scoring
The relevance of the 'Health & Safety: Employees' issue (determined by the GRESB Materiality Assessment) defines this indicator's maximum score.
For more details, refer to the Asset Scoring Basics page or download the Asset Materiality & Scoring Tool.
Scoring of Metrics
The scored metrics for Health & Safety: Employees are:
Lost time injuries (50% of HS1)
Total recordable injuries (50% of HS1)
For these metrics, participants must complete all columns to obtain points as follows:
Lost Time Injuries
25% of the total indicator score: based on a value reported for Reporting-year performance Data Coverage
The value reported for data coverage serves as a multiplier for the points available for this metric (i.e., only entities that report 100% receive the full scoring weight).
15% of the indicator score will be based on the reporting of a value in Reporting-year performance
5% of the indicator score will be based on the reporting of a target in Reporting-year target
The scoring will be based on whether a target was set, not on whether the target was achieved.
5% of the indicator score will be based on the reporting of a target in Future-year target
The scoring will be based on whether a target was set, not on whether the entity is on track to achieve the target.
Total Recordable Injuries
25% of the indicator score: based on a value reported for Reporting-year performance Data Coverage
The value reported for data coverage serves as a multiplier for the points available for this metric (i.e., only entities that report 100% receive the full scoring weight).
15% of the indicator score will be based on the reporting of a value in Reporting-year performance
5% of the indicator score will be based on the reporting of a target in Reporting-year target
The scoring will be based on whether a target was set, not on whether the target was achieved.
5% of the indicator score will be based on the reporting of a target in Future-year target
The scoring will be based on whether a target was set, not on whether the entity is on track to achieve the target.
Notes
Participants must input a target year under "Future-year target" and a numeric value in the underlying scored metric to score for this metric.
Not all scored cells/metrics are mandatory. If a scored (light green) cell is not outlined in dark green, leaving it blank will still result in a negative scoring impact. ‘This applies to the following metrics:
Lost time injuries: Reporting-year target, Future-year target
Total recordable injuries: Reporting-year target, Future-year target
Reporting of external data review is not scored.
Frequently Asked Questions
How should I calculate data coverage for performance data?
GRESB does not mandate a specific data coverage calculation methodology. Participants should report data coverage as an estimated percentage of the entity’s material facilities and activities within its reporting boundary (i.e. RC3 – Sector & Geography, and RC4 – Ancillary Activities) for which data was collected for the entire reporting year.
In the ‘Lost time injuries’ field, do I report the number injuries, or the number of hours lost due to injury?
Participants should report on the number of injuries that have resulted in lost time, and not the time lost from the injuries itself.
Do ‘Recordable injuries’ include ‘Lost Time Injuries’? What do I include in this metric?
Recordable injuries include any injury that requires medical treatment beyond first aid, as well as one that causes death, days away from work, restricted work or transfer to another job or loss of consciousness. It is not referring to near misses. This would include lost time injury, fatalities and any other injury but not near miss incidents (NMI), as NMI does not include injuries
