ARMY EYES LOW-EMITTING CO2 COOLANT TO REPLACE HFCS IN FUTURE FLEETS

The Army is considering new cooling systems for its future fleet of tactical vehicles, which rely on a low-emitting breakthrough technology that uses carbon dioxide (CO2) rather than the current technology that relies on high-emitting hydrofluorocarbons (HFCs), a major greenhouse gas, according to Army sources. "In two short years . . . the EPA has extolled the environmental advantages of using CO2 instead of [HFCs], and the Army is currently considering making [CO2-based cooling] the standard cooling system on the...
