Natural Capital: Valuing the Planet (2015) by economist Dieter Helm (Professor of Energy Policy, University of Oxford), makes accessible his work as Chairman of the UK's Natural Capital Committee, an independent advisory committee advising the UK government since 2012 'on the sustainable use of natural capital'. The book's dust cover claims the text is 'the first real attempt to calibrate, measure, and value natural capital from an economic perspective' so as 'to outline a stable new framework for sustainable growth'. As such, and given the author's position at the helm (pun intended) of one of the most significant contemporary initiatives oriented around the idea of 'natural capital', the book is an important and timely intervention.
