In the 1970s the world became aware of a huge danger: the destruction of the stratospheric ozone layer by CFCs escaping into the atmosphere, and the damage this could do to human health and the food chain. So great was the threat that by 1987 the UN had succeeded in coordinating an international treaty to phase out emissions; which, over the following 15 years has been implemented. It has been hailed as an outstanding success. It needed the participation of all the parties: governments, industry, scientists, campaigners, NGOs and the media, and is a model for future treaties. This volume provides the authoritative and comprehensive history of the whole process from the earliest warning signs to the present. It is an invaluable record for all those involved and a necessary reference for future negotiations to a wide range of scholars, students and professionals.

This book deals with various aspects of the 'commons' problems; focuses on water-related issues; looks at writings in the conservation area, with particular emphasis on irreversibility and uncertainty; and examines the role of natural resources in economic development.

This volume was assembled by two of Dr. Wantrup's students as a complement to his textbook, Resource Conservation: Economics and Policies. Wantrup's ideas on conservation economics continued to evolve in ways that were never fully reflected in that text, and although for the student of natural resource economics it is still essential reading, to stop there is to have missed some of his most valuable insights.

'Imagine the pride of earning the Nobel Prize for warning that CFCs were destroying the ozone layer. Then imagine that citizens, policymakers, and business executives heeded the warning and transformed markets to protect the earth. This book is the story of why we can all be optimistic about the future if we are willing to be brave and dedicated world citizens.' MARIO MOLINA, Nobel Laureate in Chemistry and Professor, University of California This book tells how the Montreal Protocol, the most successful global environmental agreement so far, stimulated the development and worldwide transfer of technologies to protect the ozone layer.Technology transfer is the crux of the 230 international environmental treaties and is essential to fighting climate change. While debate rages about obstacles to technology transfer, until now there has been no comprehensive assessment of what actually works to remove the obstacles. The authors, leaders in the field, assess over 1000 technology transfer projects funded under the Montreal Protocol's Multilateral Fund and the Global Environment Facility, and identify lessons that can be applied to technology transfer for climate change.
