Coke Ices Use of 'Super Greenhouse Gases'

Coca-Cola is going HFC-free. The soft drink giant announced today that it is phasing out hydrofluorocarbons — potent "super greenhouse gases" — by requiring that all new vending machines and coolers be HFC-free by 2015.

CEO Muhtar Kent told reporters he hopes the move will catalyze a shift away from HFCs in the wider commercial refrigeration market.

If it succeeds, it could be a valuable step in the fight against global warming.

Failure of 'Super Greenhouse Gas' Deal Raises Stakes in Copenhagen

Failure of 'Super Greenhouse Gas' Deal Raises Stakes in Copenhagen

At little noticed talks last week in Port Ghalib, Egypt, climate advocates were hoping to seal a global agreement for the phase down of super greenhouse gases and give next month's Copenhagen climate talks a can-do running start. But the annual meeting of the 198 nations of the Montreal Protocol began on a note of contention that five days of discussions could not overcome.

The 22-year-old Montreal Protocol has delivered an unbroken string of successes in the battle against ozone depletion, accomplished with comity and cooperation, but now observers say it has caught the climate virus. Rhetoric trumped getting down to business, as an agreement to rid the world of HFCs, enormously potent global warming gases, was postponed for at least another year.

"We're approaching tipping points fast, and we missed an opportunity to take action this year," said Durwood Zaelke, president of the Institute for Governance and Sustainable Development, who attended the talks in Egypt.
