The proliferation of environmental rating tools over the past two decades has endeavoured to assist the industry in measuring sustainability. Recent changes to the International Valuation Standards (IVS) have directed valuers to consider ESG. The purpose of this study aims to examine how commonly utilized sustainability tools, which have been employed to communicate building sustainability credentials, align with the IVS categories of ESG.

The research utilises the IVS categorisation of ESG and maps sustainability tools adopted at scale by the Australian Commercial Real Estate market. The approach identifies the various attributes within the commonly utilised rating tools that align with IVS defined ESG criteria.

The mapping provides insights into the coverage of the IVS ESG criteria in the mainstream tools used in Australia. Further, the research identifies existing sustainability criteria that are relevant to the built environment, that have not been clearly identified by the IVS, but have an important role in evaluating the sustainability of commercial real estate.

For investors, occupiers and valuers, this research provides insights on how the current, commonly utilised sustainability rating tools align with the IVS-defined ESG metrics. This research assists in providing greater clarity regarding the relationship between ESG criteria and existing rating tools, which have been recently identified as key considerations in valuation practice and help to provide transparency and understanding for property stakeholders.

The importance of monitoring, reporting and enhancing transparency in ESG disclosures has emerged as a central issue with significant implications for the property industry. This research provides the first evaluation of how existing sustainability rating tools map against ESG criteria as directed in the IVS.
