The document discusses ecosystem services and the Guide to Corporate Ecosystem Valuation (CEV) published by the World Business Council for Sustainable Development (WBCSD). It provides an overview of the CEV framework, which helps businesses improve decision-making by valuing their dependencies and impacts on ecosystem services. The guide is not meant to provide monetary values or be a standalone methodology, but rather a framework to navigate terminology and techniques. It also outlines how CEV can help businesses identify costs savings, revenue opportunities, and manage risks.
