Résumé

In September 2007, the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer agreed to accelerate the phase-out of HCFCs, a group of ozone-depleting substances that were initially promoted as substitute chemicals for CFCs. The resulting decision has the potential to prevent emissions of HCFCs equivalent to 25 billion tonnes of carbon dioxide (CO2). The agreement in Montreal presents a unique chance to control the impact of man-made fluorinated gases, known as F-gases, on the climate. The direction of the refrigeration sector over the next 30 years will be determined by which signals are sent now to the international market. This creates an enormous opportunity - but also a risk that substitute technologies will focus on hydrofluorocarbons (HFCs) which, while not damaging to the ozone layer, could have an equally negative impact on climate change.
