§ Mr. Whiteheadasked the Secretary of State for Trade and Industry if he will now publish the results of the Government study of Concorde's likely effect on the upper atmosphere, including their evaluation of the work of Dr. Harold Johnston and Dr. Paul Crutzen, relating to ozone concentrations.
§ Mr. Michael HeseltineWe have a continuing research programme on the upper atmosphere, and results will be published as they become available. Our studies indicate that the effect of Concorde's operations will be well within natural variations. The recent report of the Australian Academy of Sciences on this subject came to a similar conclusion.
