St-Rémy changed its plastic 50-cl St-Rémy XO and VSOP bottles and its 1.75-liter St-Rémy VSOP plastic bottle from PET to recycled PET plastic. With the transfer to rPET on these three formats, St-Rémy will emit 29% less carbon dioxide, and use a third less water and energy than with plastic bottles made with the traditional PET, it says.
