🌍 𝐄𝐱𝐜𝐢𝐭𝐢𝐧𝐠 𝐍𝐞𝐰𝐬 𝐨𝐧 𝐎𝐳𝐨𝐧𝐞 𝐑𝐞𝐜𝐨𝐯𝐞𝐫𝐲!

A groundbreaking study published in Nature (March 2025) has provided rigorous, quantitative evidence confirming that the global efforts to reduce ozone-depleting substances (ODSs) under the 𝐌𝐨𝐧𝐭𝐫𝐞𝐚𝐥 𝐏𝐫𝐨𝐭𝐨𝐜𝐨𝐥 are successfully driving the recovery of the Antarctic ozone layer.
Through advanced satellite observations and innovative modelling techniques, a team of scientists from prestigious institutions like MIT, Woods Hole Oceanographic, and NCAR have quantified the impact of reducing CFCs, with 95% confidence, on the recovery of the ozone hole. This confirms what we’ve been seeing qualitatively for years: 𝐭𝐡𝐞 𝐨𝐳𝐨𝐧𝐞 𝐡𝐨𝐥𝐞 𝐢𝐬 𝐬𝐡𝐫𝐢𝐧𝐤𝐢𝐧𝐠!

📅 Key Findings:
• The reduction of ODSs has led to significant positive changes in the ozone layer's recovery.
• If current regulations remain in place, we could see the ozone layer return to pre-1980 levels by 2066 in Antarctica and earlier in other regions of the world.

The study highlights the success of international agreements like the Montreal Protocol and serves as a reminder of the powerful role global collaboration plays in environmental recovery.

Recent developments in HFC regulations across Japan, Europe, and the US show significant strides towards reducing refrigerant emissions:

🔹𝐉𝐚𝐩𝐚𝐧 aims to cut HFC consumption to 11 million tonnes of CO2 equivalent by 2026, with steady progress through the adoption of low-GWP refrigerants. Emission reductions from commercial systems were observed in 2022, in line with regulatory compliance.

🔹𝐄𝐮𝐫𝐨𝐩𝐞 continues to enhance its F-Gas regulation, including amendments in 2015 and March 2024, which focus on stricter controls and mandatory technician certification. These steps are expected to raise operational standards across the EU.

🔹𝐓𝐡𝐞 𝐔𝐒, through the American Innovation and Manufacturing (AIM) Act, is targeting an 85% reduction in HFC production and consumption by 2036. The EPA’s recovery efforts in 2023 marked a notable increase, supporting the transition to more sustainable refrigerants.

The World Meteorological Organization (WMO) has confirmed that 2024 was the hottest year on record, with extreme weather events intensifying—wildfires, droughts, storms, and rising sea levels threatening millions. The consequences of climate change are no longer distant risks; they are happening now.

At the International Institute of Refrigeration (IIR), we recognise the vital role of sustainable refrigeration in strengthening climate resilience. As heatwaves intensify, reliable cold chains, energy-efficient and climate-friendly refrigeration technologies are essential for:

✔ Food security – Protecting perishable goods in extreme conditions
✔ Healthcare – Ensuring vaccine storage during heatwaves and power outages
✔ Disaster resilience – Maintaining critical refrigeration systems in emergencies

The IIR remains committed to supporting climate action through the advancement of refrigeration technologies that mitigate the effects of global warming.

📅 Join the 1st IIR International Conference on Refrigeration Adapting to Rising Temperatures (10–13 August 2025, Manchester) to explore sustainable refrigeration solutions in a warming world.

🔍 The Hidden Carbon Cost of Cold Chains in Agrifood Systems

A new study in Sustainability reveals that cold chains—vital for food preservation—are a major source of GHG emissions. In 2022 alone, cold chain-related GHG emissions hit 1.32 gigatonnes of CO2 equivalent (Gt CO2eq), with energy-related indirect emissions twice as high as direct refrigerant emissions. Household consumption and food processing accounted for 75% of these emissions, highlighting the urgent need for change.

By developing low-carbon cold chains, we can cut emissions while enhancing food security—a crucial step in tackling climate change and global hunger. Investing in energy-efficient technology, alternative refrigerants, and smart policies can help create a food system that is both resilient and sustainable.

The future of agrifood depends on rethinking refrigeration—and the time to act is now. Read the full IIR article: https://iifiir.org/en/news/new-study-highlights-the-environmental-impact-of-cold-chains-in-agrifood-systems

🚀 Revolutionary Advancement in Quantum Computing!

Big news in the world of quantum computing! Researchers have achieved 𝐫𝐞𝐜𝐨𝐫𝐝 𝐥𝐨𝐰 𝐭𝐞𝐦𝐩𝐞𝐫𝐚𝐭𝐮𝐫𝐞𝐬 to make quantum computers more reliable and efficient.

Researchers from Chalmers University of Technology and the University of Maryland have engineered a new quantum refrigerator that cools superconducting qubits to a record low temperature of 22 millikelvin—far colder than the 50 millikelvin achieved by current dilution refrigerators.

This breakthrough boosts the qubit’s probability of being in the ground state before computation to 99.97%, surpassing previous methods (99.8%–99.92%). This small yet powerful improvement is set to make quantum computations more reliable and error-free, opening the door to advancements in AI, medicine, encryption, and more.

Here’s why this is a game-changer:
✅ Ultra Low Temperatures: Achieving temperatures close to absolute zero (-273.15°C) reduces noise and errors in quantum computations.
✅ Improved Reliability: Lower temperatures stabilize qubits, making quantum computers more reliable for complex calculations.
✅ Scalability: This breakthrough paves the way for scaling up quantum systems, bringing us closer to practical quantum computing.
✅ Energy Efficiency: Advanced cooling technologies are becoming more efficient, reducing the energy footprint of quantum systems.
