Phasing out production and consumption of HFCs under the Montreal Protocol would result in climate benefits of up to 170 billion tonnes of CO2-equivalent by 2050. Island States, the U.S., Canada, and Mexico, along with other supporters of an HFC phase-down under the ozone treaty, are looking to this year's Montreal Protocol meetings to reach agreement.
"The Parties are beginning to realize that these fast-action strategies are low-hanging fruit that can, and should, be picked now if we expect to prevent catastrophic and likely irreversible consequences that are fast approaching," says Romina Picolotti, former Environment Minister of Argentina.
"For the first time in history the environment is at the top of the political agendas of world leaders," she added. "Climate change has graduated in Copenhagen and is now playing in the big leagues jointly with national security and the economy. We can only hope that our political leaders are up to the challenge and behave responsibly with the fate of the Planet and all citizens of the world in their hands."
