Are Natural Refrigerants Breaking Climate Change? IIAR’s Standards and the Evolving Global Cold Chain

As climate goals and efficiency become the central focus behind cold chain decisions, both at the individual and government level, natural refrigerants are becoming a global movement, increasingly unencumbered by regional political landscapes. In Latin America, a surge in CO₂ systems is happening, while in Europe, focus is growing on a policy-driven adoption of refrigerants like ammonia and hydrocarbons. The global regulatory landscapes remain uneven, but in many places, the tide is turning. Natural refrigerants are outgrowing national constraints, propelled by international climate agreements, evolving technologies, and a (in many cases, profit driven) drive towards sustainability and efficiency.

Industry Stakeholders Continue Work on Critical Task Guidelines

The Critical Task Guidance for Ammonia Refrigeration System Emergency Planning is a key resource designed to support employers, government regulators, and public safety responders in preparing for and mitigating ammonia-related incidents. The guidance, which was released in 2021, promotes a proactive approach to safety in facilities where ammonia refrigeration systems are in use and is currently being revised in response to feedback from users, regulatory agencies, and committee review. The first edition was developed by members of the International Institute of Ammonia Refrigeration (IIAR), Refrigerating Engineers and Technicians Association (RETA), Global Cold Chain Alliance (GCCA), and Ammonia Safety and Training Institute (ASTI). It incorporated input from multiple regulatory bodies and aimed to provide foundational safety practices.

Lesson Learned: The Value of Pre-Emergency Preparedness

Are you prepared? I think most of us think we are prepared, at least to deal with whatever we expect to happen. The trouble is that often what we come up against is not something we expected, therefore we are not prepared for that. For ammonia refrigeration whether a system has 400 lbs. or 40,000 lbs (or more) we should do pre-emergency planning and training. Having people, training, equipment, etc. in place and properly functioning before the emergency can greatly reduce the impact of an incident. The majority of people do not consider their preparation for an emergency, and only seriously think about what they should do after the emergency occurs.

Issue Date

Emergency Preparedness Means Building Relationships

Emergency preparedness is often taught as a concept supported by three critical legs of a stool: government, public safety responders, and industry. Each leg plays a vital role, and the stability of the whole structure depends on the coordination of all three, making it important for those in the industry to foster strong relationships. If facilities and first responders work together and communicate in a way they can all understand, they have an advantage. "If you've trained your team operationally to a first responder level, which means that you can have the capabilities in to address first-responder related challenges, and if you do that together with a fire service on what they can do to support on that initial first 30 minutes, you're ahead of the ball game right off the bat,” Smith said.

There are multiple regulatory requirements surrounding the use of ammonia in industrial refrigeration applications, including emergency release reporting requirements.
