The international freezing standard for food is -18 °C, a temperature that carries a huge emissions cost. What if we increased that to -15 °C?

“This temperature corresponds to 0 degrees Fahrenheit, so it was “probably a round, easy number to remember”

That’s what Allouche and team will be working on next, as they build their research summary into a full report, to be published in September 2024. “These findings give good reasons for ‘3 degrees of change’ to be further explored,” Allouche says.

    No. It’s like when toilets started getting smaller flushes. It doesn’t help on an individual basis, but as a whole it has an impact, even if it’s not a huge one.

        They’re probably already running at the optimum temperature. Power is their main input cost, and they’re strongly motivated to minimize it. Meanwhile the average household freezer is set to… Um… how about “7”. That sounds pretty cold to me, yeah?

        You wouldn’t believe how much research has gone into studying things like the optimum way to store potatoes.
