The International Institute of All-Natural Refrigeration released a new IIAR Greenpaper, a member resource for natural refrigerants. The Greenpaper, which is available on IIAR’s newly launched Resource Center, is an industry reference document that outlines the basics of natural refrigerants, and the direction the industry’s technology is taking.

In the mid-2000’s, when PFAS “forever chemicals” were first classified by the United Nations Environmental Programme, they were just beginning to be understood as dangerous pollutants. As the evidence mounted for their role in cancer and other health problems, regulators and activists began to outlaw PFAS sources, chief among them, many pesticides commonly used in agriculture.

IIAR’s annual conference this year showcased the organization’s growing scholarship program, which saw twelve new IIAR scholarships awarded. The 2026 scholars attended IIAR’s annual conference as part of a fast-growing mentorship effort led by the Natural Refrigeration Foundation. NRF has continuously increased the number of scholars each year, said John Flynn, Chairman of the IIAR Education Committee. The recipients get the benefit of a scholarship which helps defer the cost of their education, but IIAR also covers the cost of travel to the annual conference.

Are you aware of changes that happen around you? When a smell changes, or a sound changes, etc. are you so focused on your work or another activity that you don’t even notice? There are five primary senses. Smell, hearing, sight, taste, and touch. However, we actually have considerably more. Researchers have identified approximately 22 to 33 different senses. These additional senses are internal and specialized senses like balance, temperature, pain, proprioception, etc. As we become more aware of the many inputs we have, we can be better equipped to make good decisions.

Safe Work Practices(s) are critical for operating and maintaining closed-circuit ammonia refrigeration systems. Developing safe working practices is not just good for workers’ well-being, it is also good for business. The loss of systems’ functionality because of accidents, and the loss of employees’ skills because of injury is costly. It is far more fruitful to spend time to develop and practice safe work than to recover from accidents. Further, the development and engagement of safe work practices is a legal requirement in many jurisdictions and is broadly required in some countries.

The International Institute of All-Natural Refrigeration posted remembrance videos for each of its seven inductees into the Natural Refrigeration Foundation’s Legacy 100 Club. Each inductee to the Legacy 100 Club represents an impactful contribution to the advancement of natural refrigerants, said Mike Chapman, IIAR’s Vice President of Operations. “This is a chance for us to collectively name and acknowledge individuals for their contributions to our industry so that everyone is aware of the history of contributions that have helped to shape what our industry has become today.”

In December 2025, Craig J. Pritzlaff, Acting Assistant Administrator for the Office of Enforcement and Compliance Assurance (OECA), issued a memorandum that reinforces a “compliance first” orientation as the guiding principle for the U.S. Environmental Protection Agency (EPA). The policy prioritizes environmental compliance “in the most efficient, most economical, and swiftest means possible, while ensuring that our actions align with the clearest, most defensible interpretations of statutory and regulatory mandates.”
Read MoreIIAR’s newest task force has completed a gap analysis to assess OSHA and EPA’s 30-year-old PSM/RMP programs. The “NH3 Overdue Regulation Modernization,” or NORM, task force will ask regulators to remove regulatory burdens that overlap across agencies or defer to IIAR standards when the standards and regulations overlap. The task force's long-term effort will be to shift some funding and enforcement from federal regulators to state and local authorities. The NORM task force was formed to operate in a rare federal environment in which the Trump administration has opened the door to regulatory reform through Executive Order 14192, which requires agencies to take 10 deregulatory actions for every new regulation.

IIAR approved 18 Consensus Body replacements on its three consensus bodies for IIAR standards. The replacements are routine maintenance required by the American National Standards Institute (ANSI) and are completed a minimum of every five years or when individuals are no longer participating. IIAR maintains three consensus bodies, 1357, 24689 and CO2&HC. The bodies are the near-final stage of approval for IIAR standards 1,3,5, and 7, and 2,4,6,8, and 9, respectively. The CO2&HC body manages CO2 and hydrocarbons (HC).
