When we talk about natural refrigerants, R290 (propane) always makes the list. It’s efficient, widely available, and comes with one standout advantage: it has an ultra-low global warming potential. That makes it one of the most effective tools in sustainable commercial refrigeration today. What Makes R290 Different Traditional refrigerants like HFCs have high environmental impacts. R290, by comparison, has a global warming potential (GWP) of just 3. To put that in perspective, some commonly used refrigerants have GWPs in the thousands.

If you run a small grocery or convenience store, you might think your footprint is too small to matter. But the truth is, sustainable commercial refrigeration in smaller stores adds up quickly. Every upgrade to efficiency or choice of natural refrigerants can lower your operating costs - and it also equates to thousands of small wins across the industry that create a real impact for the environment. Why Small Stores Matter Supermarkets usually get the spotlight in conversations about sustainability, but smaller retail spaces are everywhere. Together, they use a tremendous amount of energy.

Businesses looking to cut energy costs and reduce environmental impact must choose refrigeration systems that deliver both efficiency and performance. Sustainable commercial refrigeration is a necessity. Two popular options for businesses are distributed refrigeration systems and centralized refrigeration systems. Both designs have strengths, but which one suits your business best? What Are Distributed and Centralized Refrigeration Systems? Distributed refrigeration systems are placed closer to the cooling load across multiple smaller compressors.

Climate change is shaking up industries everywhere, and commercial refrigeration is no exception. Whether temperatures rise or fall, refrigeration systems have one job: keep food products cold at a steady, precise temperature. But when the weather swings wildly, these systems have to work harder. In short, climate change does affect sustainable commercial refrigeration, but not in the way you might think. Why Temperature Fluctuations Matter Refrigeration systems are designed to maintain a set temperature range, regardless of outside conditions.

So when they started planning for the development of their new Highland Bridge location in St. Paul, they naturally looked at a range of CO2 refrigeration system options.

Quick Takeaways:

• The DOE has repealed key energy efficiency rules for commercial refrigeration systems.
• Kysor Warren is staying committed to sustainable commercial refrigeration, regardless of regulatory rollbacks.
• Our systems—built on natural refrigerants and high-efficiency engineering—are designed to meet customer needs now and in the future.
• These regulatory changes may affect the broader industry, but the market demand for energy-efficient, eco-conscious systems remains strong.

If you’ve been following the regulatory la

It’s not your imagination: summer feels hotter, your utility bills keep climbing, and every new smart device seems to plug into an already strained grid. Between record-breaking heat waves and the meteoric rise of AI-powered everything, energy demand is surging. Air conditioners are working overtime. Data centers are humming 24/7. And the pressure to operate more sustainably has never been greater. For businesses that rely on refrigeration, this creates a double bind.

What’s the difference between a high-efficiency refrigeration system that works and one that lasts? The answer is simple: it’s the people behind it. As the commercial refrigeration industry moves quickly toward lower-emission, natural refrigerant-based technologies, the demand for skilled professionals who understand transcritical CO₂ systems is increasing. That’s where Kysor Warren steps in.

The future of commercial refrigeration is here—and it’s sustainable, efficient, and ready to plug in. Kysor Warren’s self-contained refrigerated display cases (including the Shuffle KW, Valzer KW, Tango KW Compact, Opera T, and Overture) are the dependable, eco-conscious solutions your store needs. These units are quietly revolutionizing the industry, delivering powerful performance, energy efficiency, and environmental responsibility—all in a plug-and-play format. Plug In. Cool Down. Sell More. No pumps. No drains. No complex installations.

As sustainability becomes more than just a buzzword for retail grocery and turns into a mandate from customers, regulators, and the planet, the refrigeration systems behind the scenes are taking center stage. At the heart of this shift there is one solution that’s quietly changing the game: distributed refrigeration systems.
