Valuing the invaluable: how much is the planet worth?
批判性分析了自然资本的不同估值方法，探讨了经济价值应用于自然资本的问题与局限，并比较了会计学中的工程成本法，旨在厘清估值背后的核心问题。
This article explores the valuation of natural capital by critically analysing alternative approaches to it. It considers the problems associated with applying economic values to natural capital and the limitations of such exercises. It examines different methods that are more familiar to accountants than economists of using what is sometimes termed ‘an engineering approach’ to estimating the costs of maintaining and restoring existing assets. It considers the arguments that are used to justify the two. In particular, it addresses the question of what we are seeking to do by determining the value of natural capital—what is the question to which valuation is supposed to be the answer?
