But Ben and Jerry, isn't a lot of fossil fuel still burned in the process of producing, distributing, and storing your completely non-essential ice creams?

Ben & Jerry's Launches a New Kind of Cool - MarketWatch

"We've been working on getting better refrigeration technology into our distribution networks in the U.S since 2001, and more specifically on hydrocarbon freezing for the past year," says Gosselin. For now, the efforts from the team including Ben & Jerry's, Unilever, Greenpeace and others can claim moderate success with approximately fifty freezers this fall, with approval to test up to 2,000 freezers in the next few years.
"This climate-safe freezer will keep pints of Chunky Monkey and Cherry Garcia as cold as ever, but it's also going to help cool our planet," said John Passacantando, Executive Director of Greenpeace USA. "With hurricanes intensifying, tropical disease spreading, sea levels rising, and polar bears going extinct, we need to make sure that what cools our ice cream, drinks, and homes isn't also melting the ice caps."

Hydrocarbon Freezers

We believe HC freezers can be a big part of the solution. The HC gases we’re using in our Cleaner, Greener Freezers — purified propane — are just as effective at cooling a freezer as HFCs and are 10% more energy efficient. But HC’s contribute almost nothing to global warming, and have zero impact on ozone depletion. Now, that’s progress!
