Abstract: Purpose - The purpose of this study is to explore the feasibility of natural capital accounting for the purpose of strengthening sustainability claims by reporting entities. The study showed how riparian land improvement influenced ecosystem services which could be measured in the context of financial reporting. The authors tested options for incorporating natural capital concepts into financial accounting practices under existing accounting standards specifically: on the balance sheet. Design/methodology/approach - A case study approach was used with an Australian water utility that has accountabilities to protect the environment, including maintaining and enhancing riparian land assets. The authors examined internal data sources, stakeholder engagement outcomes, physical assets, monetary valuation processes and financial recognition of natural capital income and assets. Natural capital income was estimated by process-based ecological modelling and ecosystem services were valued in relation to stormwater filtration and carbon storage using data from both internal and external sources. Findings - The authors demonstrated how an environmental agency can disclose natural capital as a class of assets on the balance sheet. The authors also found that current accounting standards allow the recognition of some types of environmental assets where ecosystem services were associated with cost savings. The proof-of-concept used for asset measurement through ecosystem service modelling proved useful to strengthen sustainability claims or report financial returns on natural capital investment. Originality/value - While many studies have examined environmental disclosures in voluntary reports, this study established that natural assets can be included on the balance sheet of financial statements, offering a robust approach to measuring and reporting on natural capital. It did so by applying financial accounting processes and principles to a real-world natural capital management scenario with direct participation and cooperation between the asset manager, academic researchers and a government environment agency, bridging the gap between theory and practice.
