Book excerpt: This unique dictionary and introduction to Global Environmental Governance (GEG), written and compiled by two veterans of the international stage, provides a compilation of over 5000 terms, organizations and acronyms, drawn from hundreds of official sources. An introductory essay frames the major issues in GEG and outlines the pitfalls of talking past one another when discussing the most critical of issues facing the planet. It challenges those who are concerned with the management of our planet and its inhabitants to understand and accept a vocabulary common to the often-opposing objectives sought in the many GEG instruments.The result is a practical tool that should find a central place on the desk of anyone involved in environmental management, development or sustainability issues anywhere in the world, including the United Nations, government policy makers, NGOs and other stakeholder groups, the business community, and students and professionals.
