In December 2009, Coke announced that 100 percent of their new vending machines and coolers will be HFC-free by 2015. Coca-Cola is using two HFC-free solutions: hydrocarbon refrigeration is used in smaller refrigeration equipment and carbon dioxide (CO2) is used in larger equipment. Coca-Cola committed to use its scale to aggregate demand and encourage supply as a means of accelerating the transition to HFC-free refrigeration equipment.
We're also currently working with a consortium of global companies to change the world's refrigeration and cooling. We've used carrots and sticks with these businesses, and our efforts have resulted in surprising alliances. Refrigerants, Naturally! was founded by Coca-Cola, McDonald's, and Unilever in 2004 to encourage the elimination of F-gases from refrigeration and cooling. We work with these companies and many others by pushing for rapid change and constantly reminding them of the consequences of inaction. Just as importantly, we try to ease their way to a green solution by educating and developing the market and changing the policies so that the choice for natural refrigeration is also a profitable choice. It's expensive to retool a factory and there are many ways to mitigate these large investments.
