HFCs: Finally Phasing Out One Man-Made Problem?
ECO was pleased to wake up Sunday to the news that Presidents Obama and Xi had agreed to work together to combat climate change by phasing down the super greenhouse gases, hydrofluorocarbons (HFCs), under the Montreal Protocol. An agreement under Montreal could prevent emissions of 100 billion tonnes CO2e by 2050.
First that great party on Saturday, and then this?! For a while now, the EU has been busy pushing a COP decision at Warsaw that will urge Parties to begin this exact same process under the Montreal Protocol, and they are clearly excited to have China and the US in agreement.

All eyes are now on the next intersessional meeting of the Montreal Protocol happening in a few weeks, hoping it will turn this political arrangement into concrete, short-term action, which must not stop at phasing down, but start phasing out with appropriate finance and technology support to developing countries. HFCs are human-manufactured chemicals, primarily used in refrigeration, air conditioning and foam blowing, which were commercialised to replace the high-Global Warming Potential, ozone depleting, human manufactured chemicals phased out by the Montreal Protocol over the past 25 years.
Yet, HFCs are also extremely harmful to the climate, with global warming potentials much higher than carbon dioxide.
