Injury rates (G4-LA6-a) Methodology

history edit build

In 2018, the GRI G4 Sustainability Reporting Guidelines were superseded by the GRI Sustainability Reporting Standards (GRI standards). This is the methodology for G4-LA6-a which has been superseded by GRI 403-9-a - the current GRI 403-9-a metric can be found here.

About

This metric is based on the Global Reporting Initiative (GRI) G4 Guidelines. It covers one of the requirements of Indicator G4-LA6 – ‘Type of injury and rates of injury, occupational diseases, lost days, and absenteeism, and total number of work-related fatalities, by region and by gender’.

This indicator also asks for type of injury, occupational diseases, lost days, and absenteeism, and number of work-related fatalities, by region and by gender, for the total workforce (total employees plus supervised workers) and for independent contractors working on-site). (G4-LA6-a, G4-LA6-b)

Health and safety performance is a key measure of an organization’s duty of care. Low injury and absentee rates are generally linked to positive trends in staff morale and productivity. This indicator shows whether health and safety management practices are resulting in fewer occupational health and safety incidents. An evaluation of trends and patterns may also indicate potential workplace inequity.

Methodology

This metric is looking for the workforce injury rate (the number of injuries per million hours worked by the total workforce in the reporting period).

"Lost time injury rates" are not appropriate for this metric, this metric is about recording the number of injuries. If this is presented as a ratio other than "per million hours worked", please convert it to "per million hours worked".

For Wikirate researchers:
Companies who align reports to GRI’s Sustainability Reporting Standards often include a GRI Content Index or Annex where GRI disclosures, with GRI codes, are listed.

  • Use the GRI Index, CTRL F, Command F or search button on source preview to search for this index and metrics within the report

  • Use G4 codes, G3 codes or keywords to quickly find values, keeping in mind that some companies report on the metric using different terms, e.g. G4-LA6 or LA6, injury rate or IR. Total recordable injury/incident rate (TRIR) is also sometimes used as a label for this kind of data.

  • Always check the metric question and methodology for the unit of measure or currency - researchers may need to carry out calculations or conversions before entering the final metric value

  • Add comments documenting exactly where within the source you found the information (page number) and include details of simple or complex calculations or conversions made to determine the metric value

  • If you are unable to locate a metric value in a source you can search for additional sources where the data is available and add a new source

Further guidance on how to research values for GRI-based metrics is available here, including detailed guidance on adding, editing and checking metric values.

Global Reporting Initiative compliance guidance for companies:

To calculate the injury rate - G4-LA6-a:

  • Identify the injury rate (IR) experienced during the reporting period

  • Report this information for the total workforce (that is total employees and supervised workers)

Reporting on this Indicator should include the following contextual information as a comment to the metric value:

  • G4-LA6-c: ​The system of rules applied in recording and reporting accident statistics.
