Honeywell is committed to helping customers achieve their sustainability goals by transitioning away from high global warming potential hydrofluorocarbons (HFCs) to next-generation solutions that can minimize the impact of climate change. Honeywell has invested in research, development, and new capacity for its innovative Solstice® technology, which uses breakthrough hydrofluoroolefin (HFO) technology to reduce carbon footprint without sacrificing performance. Solstice® products are currently being used in applications such as propellants for personal and household care; refrigerants for supermarkets; air conditioning for cars and trucks; blowing agents for insulation; and solvents for cleaning solutions. Solstice® technology is currently being evaluated in Metered Dose Inhalers.

Solstice® Air is a breakthrough medical propellant currently in clinical development for pressurized metered dose inhalers (pMDIs) with the ability to help reduce greenhouse gas emissions. A near-zero global warming potential (GWP) alternative to hydrofluorocarbons, Solstice Air is non-flammable (per ASTM E-681 and ISO 10156), non-ozone depleting, and VOC-exempt (U.S. EPA and CARB).
