Currently, many industries have products with temperatures that are around minus -18 degrees Celsius, and the temperature of freezers in the trials would be around -12 degrees Celsius.
"If the trials end up being successful when it comes to reducing greenhouse gas emissions, as long as the ice cream products are not affected too drastically, other ice cream industries could potentially follow in their footsteps," said Matt Close, president of of Unilever ice cream business, in a press statement.
"These pilots will provide valuable information on how much energy we can save and how our ice cream products perform in warmer freezers to ensure we deliver the same great-tasting ice cream," Close added. "We're actively seeking to collaborate with partners from across the ice cream and frozen food sectors to drive industry-wide change, so the collective positive impact is far greater."
As reported by Unilever, emissions from ice cream freezers cause around 10% of their greenhouse gas footprint. Therefore, they will now evaluate energy usage in addition to "product performance" of the ice cream at the minus 12 degree Celsius temperature. Approximately 10% of the company's greenhouse gas emissions are from ice cream freezers.
Next month, more trials will be held for the decreased freezer temperatures in both Germany and Indonesia. Unilever's ultimate goal is to eventually work with countries whose carbon footprints are the highest, so as to "achieve the maximum reductive impact" on carbon dioxide.
According to various data, in 2021, total scope 1 and scope 2 emissions amounted to 710, 740 metric tons of carbon dioxide. So if Unilever's trials prove to be successful, by the year 2039, Unilever will eventually achieve net zero emissions throughout their value chain.
