We are thrilled to welcome Arneg USA into our community. Globally, Arneg has shown great leadership in advancing natural refrigerants, and we look forward to working with them to advance naturals in North America.

-Danielle Wright - Executive Director, NASRC .

Natural refrigerants, including carbon dioxide (CO2), ammonia (NH3) and hydrocarbons, have extremely low global warming potentials (GWPs), and as a result are considered “climate-friendly.” In some cases, natural refrigerant technologies offer energy efficiency benefits that lower operational costs in the long-run.

Despite their benefits, natural refrigerants are not yet widely adopted by supermarkets due to significant market barriers, including cost, codes and standards, and service readiness. The NARSC works directly with industry stakeholders like Arneg USA to address these barriers head-on. 

Arneg USA is part of the global Arneg group, who is an international leader for the advancement of natural refrigerants. The global organization has hundreds of CO2 systems running and thousands of propane self contained cases placed.

We are pleased to join NASRC and intend to utilize our advanced European natural refrigerant experience in an effort to help accelerate change in the market.

- Howell Feig - Vice President of Sales and Marketing, Arneg USA

In addition to manufacturers like Arneg, NASRC members represent all factions of industry: including service contractors, consultants, engineering firms, trade associations, nonprofits, refrigerant distributors, and over half of the supermarket locations in the United States.

Naturally Cool: NASRC's New Commercial Track at IIAR Conference & Expo


For the first time, the North American Sustainable Refrigeration Council (NASRC) has curated a NEW Commercial & Food Retail Track for the 2019 IIAR Conference & Expo (March 3-6, Phoenix, Arizona). While this event has traditionally focused on the industrial sector, this new track will incorporate the NASRC’s network of industry experts to explore groundbreaking ideas and trends in commercial refrigeration through technical papers and presentations, and panel discussions.

The IIAR Conference & Expo is widely recognized for bringing together a diverse group of industry experts to provide the largest natural refrigerants product exhibition in the United States, highlighting the latest technology innovations and products from leading manufacturers, contractors, and other service providers. With over 1,500 attendees last year, this conference provides opportunities to network and collaborate with some of the greatest minds in the natural refrigeration community.

Get a sneak peak of a few of the Commercial & Food Retail Track sessions below:

Case Study: The First Commercial Propane/Carbon Dioxide Cascade Refrigeration System in North America

This technical paper and presentation will discuss the first and only propane/CO2 cascade system in a North American supermarket, a pilot project intended to investigate the viability of this previously unused system option. Authors will explore the project roadmap and system design, approval and permitting process, cost comparison, and performance to date of this unique system.  

Supermarket Experiences With Low-Charge Ammonia

This panel discussion will mark the first discussion of end-users who have adopted ammonia/CO2 cascade systems. Panelists will examine their experiences with low-charge ammonia, including system performance, and barriers to adoption. This session will provide insights around questions, such as whether the perceived danger of ammonia is a true barrier, and what other barriers have prevented more supermarkets from considering low-charge ammonia systems.

Ready Or Not: Is Commercial Service Readiness A Barrier To Adoption?

Service readiness, including availability of service technicians, training resources, and certification programs, is often cited as a barrier preventing the adoption of natural refrigerant technologies. But is service readiness truly a barrier? Or is it a symptom of low adoption rates? This panel, composed of end users and service contractors, will explore this question and identify areas to address this barrier, true or perceived.

NASRC Seminar Highlights Roadmap to “Future-Proof” HFC Alternatives in Supermarkets


Baltimore, Maryland – On January 10th, the North American Sustainable Refrigeration Council (NASRC) presented a Natural Refrigerant Seminar and Live CO2 Demo at the Danfoss Headquarters. Sponsored by CoolSys and Danfoss, the seminar shared insights on natural refrigerant applications in supermarkets, and why they are considered a “future-proof” alternative to HFC refrigerants. This seminar was attended by food retail end-users, service contractors, and other commercial refrigeration stakeholders, as well as utilities, government agencies, and nonprofits.

Danielle Wright, the Executive Director of the NASRC, kicked off the seminar with an overview of natural refrigerants, which include ammonia, carbon dioxide (CO2), and hydrocarbons. Wright discussed the significant climate benefits that natural refrigerants offer compared to commonly used hydrofluorocarbon (HFC) refrigerants, citing that HFC refrigerant leaks in U.S. supermarkets result in roughly 152 billion pounds of CO2e emissions annually. Wright also reviewed the wide range of natural refrigerant equipment options available on the market and the benefits and barriers to adopting these technologies.

One significant factor driving food retailers to consider natural refrigerant options is the increasing refrigeration regulations at the state, federal, and global level. Christina Starr of the Environmental Investigation Agency (EIA) provided an overview of current refrigerant regulations and the role they are playing in the adoption of natural refrigerants. Most notably, Starr discussed the increasing commitments to reduce HFCs at the state level. Given the considerable climate benefits that low-GWP refrigerants offer, many states are announcing HFC regulations to help meet their climate goals. California was the first state to make a commitment to phase-down HFCs, with a goal of reducing HFC emissions by 40% by the year 2030. More recently, New York, Connecticut, Maryland, and Washington have announced HFC regulatory commitments.

“It is critical for States to understand the burden HFC regulations place on the supermarket sector,” said Danielle Wright of the NASRC. “Food retailers have a huge potential to help these states accomplish their climate goals, especially if proposed regulations reduce the barriers preventing the adoption of climate-friendly refrigeration alternatives.”

Incentive programs for low-global warming potential (GWP) refrigerants are one solution states are exploring to help offset the incremental costs that have been cited as a barrier to supermarket adoption of natural refrigerant-based technologies. Incentive programs have the power to accelerate the adoption of low-GWP refrigeration technologies, moving them closer to reaching economies of scale. Thus, these programs can decrease the cost barriers that prevent many supermarkets from adopting low-GWP technologies beyond the states administering the programs. In California, Senate Bill 1013 was signed into law in 2018, which included the approval of a state-wide incentive program for low-GWP refrigerants. Other committed states have announced an interest in pushing for incentives as well.

The second half of the seminar focused on CO2 as a refrigerant. Tony Lundell and Eric Smith of the International Institute for Ammonia Refrigeration (IIAR) presented on the status of their CO2 safety standard, expected to be finalized within the next year. This standard is intended to specify the minimum requirements for the safe use of CO2 as a refrigerant in industrial and commercial applications.

Peter Dee of Danfoss followed IIAR, with an overview of the “mega-trends” the commercial industry is experiencing, such as a rise in digitalization, increasing urban populations, and a changing climate. He also shared insights on the technological advances that have improved the performance of CO2 transcritical systems, allowing this technology to be adopted by more supermarkets. With refrigeration accounting for roughly half of a supermarket’s annual electricity use, the energy performance of a system is a significant cost consideration. The improved performance of CO2 transcritical has made it a viable option for more supermarkets in more geographic locations.

Danfoss closed the seminar with a live demonstration of a CO2 transcritical system using their mobile training unit. Attendees left the event with a more in-depth understanding of natural refrigerant options, the latest technology trends, and the barriers and solutions influencing the adoption of these technologies.

The NASRC is a 501c3 nonprofit organization focused on advancing natural refrigerant adoption in supermarkets. The organization specializes in facilitating regionally focused and interactive events that leverage the expertise from their extensive network of members. NASRC members include manufacturers, service contractors, consultants, engineering firms, trade associations, nonprofits, refrigerant distributors, and nearly 21,000 supermarket locations in the United States.
