Target and Amazon have both recently announced plans to construct new stores that contain CO2 refrigeration systems, which will help the retailers significantly reduce carbon emissions and energy use.
Target Corp. announced that its Vista, California, store will generate more renewable energy than it needs annually to operate and that it will test multiple innovations to reduce the building's emissions. The store will generate renewable energy through 3,420 solar panels across its roof and newly installed carport canopies. The site is expected to produce up to a 10% energy surplus each year that it can transmit back to the local power grid, and Target has applied for net zero energy certification from the International Living Future Institute.
