Global Reporting Initiative (GRI) G4 ASSA ABLOY has reported its sustainability performance in a separate sustainability report since 2006. As of 2007 we apply the Global Reporting Initiative Guidelines for voluntary reporting of sustainability performance, version 3.0. The GRI guidelines provide a framework for what information to include and a set of indicators to report the actual sustainability information. Since 2012, ASSA ABLOY reports on level B. The reporting level is confirmed by third party. ASSA ABLOY’s GRI content index is included in the sustainability report The GRI Guidelines are the most commonly used regarding sustainability reporting. The 2015 report has been developed with guidance from a number of standards and with substantial input from investors and available rating schemes, in particular the GRI Guidelines. The 2015 report adheres to GRI G4 guidelines at core level. Accordingly, the GRI indicators have been chosen to match the material issues disclosed on page 4 of the report. Omissions or incomplete data are commented on directly in the GRI index on pages 26–27 in the report. ASSA ABLOY reports its sustainability performance annually. The most recent Sustainability Report, for 2014, was issued in March 2015.
