The guide describes how to value the environmental impacts typically associated with business activities: air pollution, greenhouse gases, land use, solid waste, water consumption, and water pollution. Developed by PwC’s Total Impact Measurement and Management (TIMM) team the guide is based on PwC's extensive experience measuring and valuing natural capital. It is consistent with the Natural Capital Protocol recommendations for monetary valuation and ISO 14008. PwC was part of the core team that developed the Natural Capital Protocol. The guide itself and Kering’s pioneering Environmental Profit & Loss (EP&L) (supported by PwC) were two of the four proprietary methodologies selected by the Coalition’s Methodological Review Panel to inform the development of the Protocol. PwC were also central to The Economics of Ecosystems and Biodiversity (TEEB), the WBCSD’s Guide to Corporate Ecosystem Valuation and the UK government’s Framework for Corporate Natural Capital Accounting.
