Valuing sustainability part 1: a review of sustainability consideration in valuation practice

Purpose - The research investigates valuers' understanding of the value of sustainability in property and its consideration in valuation practice. The paper explores the extant research that has examined valuers' perceptions of the relationships between sustainability and market values, sustainability measurement, value relationships and the standards and guidelines released industry bodies. Design/methodology/approach - This paper, part 1 of 2, reports the current state of play of valuation research in the consideration of sustainability in valuation practice and the role of industry bodies in the guidance regarding sustainability consideration in valuation. The second paper provides the next rendition of a longitudinal study examining valuation practice in Australia. Findings - The paper provides an overview of the evolution of the consideration of sustainability in property over the past two decades. Providing insights of how the property sector, its markets and valuation professionals have responded to answering the questions of: what is the value of sustainability? Whilst earlier publications both industry and academic publications alike focussed on the normative aspects of how sustainability should affect value, more recent research starts to ascertain the implications of sustainability on property values. Despite industry bodies providing information, education, guidelines and standards, it would seem that valuers in their practice are still grappling with the challenges of understanding the rapidly evolving area of sustainability, environmental, social and governance and climate risks in valuations. Research limitations/implications - The paper does not present as an authority on all research that has been conducted to date, it provides an overview of the evolving nature of both academic research and industry consideration of sustainability, particularly in a valuation context. This provides the background for Part 2. Practical implications - The broader agenda of net zero, climate change, mitigation and carbon requirements, whether driven by market forces or government legislation, are generating substantial changes in property markets, as investors reconsider their positions and model the implications of carbon emissions on their bottom lines. Government policies appear to have a considerable influence over market behaviours, which filters through to stakeholder decision-making. However, despite government policies, clear market signalling and industry body guidance on valuing sustainability, the content and depth of sustainability consideration in valuation are still limited. Originality/value - The paper provides an overview of the last decade of research into the value of sustainability and the evolving nature of information and guidance for valuers to identify, evaluate and consider sustainability in valuation.
