Honeywell to help Walmart reduce its carbon footprint

Reduced global warming potential (GWP) solution is supermarket industry's most widely accepted replacement for higher-GWP solutions

Honeywell announced that Walmart will use its reduced global-warming-potential refrigerant Solstice N40 (R-448A) in some stores in Mexico and Central America.

The project will cover more than 160 new supermarket refrigeration systems in the region. The use of Solstice will help Walmart reduce its carbon footprint and improve energy efficiency. This project represents a potential reduction of 130,000 metric tons of CO2e.

Based on hydrofluoroolefin (HFO) technology, Solstice N40 offers a global warming potential (GWP) that is approximately 68 percent lower than legacy hydrofluorocarbon (HFC) refrigerants like R-404A. Solstice N40 is the supermarket industry's most widely accepted, lowest GWP, nonflammable replacement for R-404A, with more than 60,000 installations globally since its release in 2015.

"With the adoption of Solstice N40, Walmart de México y Centroamérica joins the industry chorus who have sung the praises of this solution-- a cost-effective refrigerant with reduced global warming potential that meets high standards for performance and energy efficiency in commercial refrigeration," said Ken West, president and CEO, Honeywell Advanced Materials. "We are proud to assist Walmart in meeting its sustainability targets, which are aligned with Honeywell's own commitment to carbon neutrality."

Solstice N40 offers GWP that is approximately 68 percent lower than legacy HFC refrigerants like R-404A. In addition, Solstice N40 consumes less energy. In U.S. and European supermarket trials that compared Solstice N40 to R-404A, Solstice N40 refrigeration systems demonstrated an average of between 5% and 15% lower energy consumption.
