The Impact Of Ozone Layer Depletion

Global Environment Monitoring System.

This report examines key issues surrounding ozone depletion, beginning with the status of the stratospheric ozone layer and the causes of depletion of this layer. Impacts of ozone depletion and the consequent increase in ultraviolet-B radiation are reviewed along with global and Canadian initiatives to protect the ozone layer. This is followed by review of ozone layer protection initiatives in British Columbia. Finally initiatives that should be carried out in the near future by the provincial and federal governments are identified. Appendices include information on the ozone depleting potential of various chemicals, ozone-depleting substance phase-out dates, and key requirements of the provincial Ozone-Depleting Substances Regulation.
