Want to Buy a Climate-Friendly Refrigerator? Leading Manufacturers Are Finally Providing the Information You Need The change came after I went out of my way to buy a green fridge, only to have a climate bomb delivered to my house.

Until the past few years, it’s been virtually impossible to buy a full-sized refrigerator in the United States that uses climate-friendly refrigerants like isobutane.
