Data on ozone depletion available

Environment Canada has published an update on indicators of key trends related to stratospheric ozone depletion. The indicators provide reliable information and data on the status of the ozone layer and progress being made to reduce man's impact on it. Much progress has been made in reducing ozone depletion in Canada since the introduction of a ban on the production or importation of chlorofluorocarbons (CFC), but CFCs are still found in old appliances and stocks that existed prior to the ban are still being used. Free copies of the update are available from State of the Environment Directorate, Environment Canada, Ottawa ON K1A 0H3; tel: 800 668-6767; and fax: 819 953-2225.
