Target and Amazon both announced the launch of environmentally friendly store models recently. They are applying for certifications from the International Living Future Institute (ILFI) for the locations. The stores have facilities, including an electric HVAC system and CO2 refrigeration to bring down emissions.

Target unveiled its first net-zero energy store in Vista, California, while the Amazon sustainable store in Seattle is seeking the world's first Zero Carbon certification.

According to Target's press release, the store will produce more sustainable energy than it needs to operate annually, and it will also test several innovations to reduce the building's emissions. There are 3420 solar panels installed across its roof to generate renewable energy. The new carport canopies at the firm will also help generate sustainable energy. The site will likely produce up to 10 per cent surplus energy every year that it can transmit back to the local power grid.

Target, at its store, has an electric HVAC system, which will be powered using rooftop solar panels instead of natural gas. The store has also shifted to CO2 refrigeration, a natural refrigerant that facilitates the firm to scale down its direct emissions by 20 per cent by 2040.

Meanwhile, the Amazon Seattle store will save 185 tons of CO2 emissions every year. The store has a CO2-based refrigeration system, which reduces greenhouse gas emissions by 38 metric tons per year compared to traditional methods. It also has a fully electric kitchen space that reduces fossil fuel dependency. The company expects to power its global operations with 100 per cent renewable energy by 2025.
