Valuing externalities in a business context

Introduction

Companies are becoming increasingly aware of the environmental and social costs that may be involved in the production of goods. Usually, these costs are not included in the final cost of the goods and are known as 'externalities'. Externalities include, for example, the depletion and pollution of water sources and waste from production processes.

The goal of this project was to develop standard methods for the valuation of externalities associated with the production and consumption of commodities, and to provide evidence for policy engagement about the sustainable and equitable management of natural capital.

This project was undertaken by the Valuing Nature Network, the Cambridge Programme for Sustainability Leadership and the Natural Environment Research Council.

Case studies

The project brought together 12 major businesses across a number of sectors and economists and ecologists from the Valuing Nature Network interdisciplinary community to conduct detailed case studies.

The work was based on is two exemplar studies: the value chain of cereals and the use of water.

The project was co-funded by the Valuing Nature Network and the Cambridge Programme for Sustainability Leadership, with additional funding from the Natural Environment Research Council.
