South Sudan ratified the Kigali Amendment on 23 October 2026, becoming the 176th country to do so. As a Group 1, Article 5 party, it must freeze HFC production and cut HFC consumption by 80% by 2045, while also reducing HCFC use by 65% against its 2009–2010 baseline.
A 2026 review in Applied Thermal Engineering outlines four approaches to extracting freshwater from air — condensation, sorption, radiative cooling, and hybrid systems — and highlights MOFs operating at 10–20 % relative humidity and a solar-powered thermoelectric prototype as key advances. The IIR's 60th Technical Brief positions refrigeration-based AWH as a contributor to UN Sustainable Development Goal 6.
A new open-access review in Foods examines how active packaging can preserve the sensory quality of fresh fruits during refrigerated storage, where low temperatures may suppress key aroma volatiles. The authors stress that every active-packaging function carries a dual effect on flavour and that system selection must account for fruit-specific physiology and a full safety-validation window.
