Leading Together – Valuing Nature in Business


Companies must anticipate that ecosystem valuation will be more consistently incorporated into public policies, regulations, and political decisions. Ecosystem values will also be increasingly considered by the finance sector and business-to-business customers as they assess the biodiversity and ecosystem-related risks and opportunities of investments and supply chains. In this context, the WBCSD released the Guide to Corporate Ecosystem Valuation (CEV) in 2011, a framework for improving corporate decision-making by enabling companies to consider the actual benefits and values of the ecosystem services they depend and impact on. It is the first of its kind, catering directly for the needs of business. It was developed with fourteen member company road testers and four partners: International Union for Conservation of Nature (IUCN), World Resources Institute (WRI), ERM and PwC.
