Induced innovation and international environmental agreements: evidence from the Ozone regime

  • Dugoua, Eugenie

Abstract

Global environmental problems are some of the most pressing issues that humanity is facing. There are few examples of success at resolving them; the fight to protect the ozone layer is one of them. This paper provides evidence that the Montreal Protocol’s restrictions on chlorofluorocarbons ( CFCs) triggered a substantial increase in research and innovation on alternatives to ozone-depleting molecules. I compare CFC substitute molecules to molecules that have similar uses but are unrelated to ozone depletion. After the signing of the agreement, patents on CFC substitutes increased by 400% and scientific articles by 500% compared to the control group. These findings suggest that agreements can indeed trigger the development of technological solutions, thereby improving the benefit-cost equation of environmental protection
