How Did We Save the Ozone Layer?

BBC Radio 4 - Analysis, How Did We Save the Ozone Layer?

The story, and lessons, of the international effort to end ozone-destroying chemicals.

Helena Merriman tells the story, and lessons, of the international cooperative effort to eliminate ozone-destroying chemicals.

On 30 June this year, a study was released in one of the world's top scientific journals. It explained how a group of scientists who had been measuring the amount of ozone in the stratosphere had made a startling observation: the hole in the ozone layer had shrunk. Here, they said, was the first clear evidence that the ozone layer had begun to heal. So how did this happen?

Helena Merriman tells a story that involves dogged scientific endeavour, the burgeoning green movement of the 1980s and the signing of what has been described as the most successful treaty ever created. 

Producers: Lucy Proctor and Hannah Sander.

Intelligent speech, the most insightful journalism, the wittiest comedy, the most fascinating features and the most compelling drama and readings anywhere in UK radio.
