The Move to -15 °C—an industry effort to lower frozen food storage and transportation temperature standards—has more than doubled its membership since its launch in 2023, representing stakeholders at every stage of the frozen food supply chain. The group was founded following the release of the Three Degrees of Change report, an academic paper providing evidence that a move from -18 °C to -15 °C could make a significant environmental impact without compromising food safety.

The frozen food temperature set point of -18 °C was established as an industry standard a century ago—a decision supported by little evidence. Logistics technology has improved substantially since that time, and scientific literature shows that a 3 °C change in temperature could:
