Ozone protection feels the heat (BBC) {HFCs vs HCFCs vs CFCs vs ...}

Former UN chief Kofi Annan described the 1989 Montreal Protocol to protect the ozone layer as "probably the most successful environmental agreement to date". But in this week's Green Room, Fionnuala Walravens considers how the complex interactions of ozone depletion and climate change in the atmosphere are mirrored in the global political debate.

The Montreal Protocol, the international agreement designed to protect the ozone layer, has reached a major crossroads.

Last year's 20th anniversary meeting of the global framework to protect the ozone layer agreed to significantly accelerate the phasing-out of ozone-depleting hydrochlorofluorocarbons (HCFCs).

This was applauded worldwide as an historic achievement that could also save billions of tonnes of greenhouse gas emissions, because HCFCs are many thousands of times more potent than carbon dioxide.

However their likely replacements, the ozone-benign hydrofluorocarbons (HFCs), are also potent global warming gases, often more destructive than the HCFCs they are replacing.
