Stores and Warehouses
We have a big responsibility, but also a big opportunity, to reduce the environmental impact of our stores. We’re always looking for ways to improve, from equipping stores and warehouses with solar panels, using LED lighting both inside and out, and installing efficient HVAC systems, to phasing out high global warming potential refrigerants in our refrigeration compressors. In fact, our new stores have been equipped with all LED lighting since 2015. We carefully design our stores, warehouse and administration buildings and use materials to meet leading global green building standards.
All of our warehouses’ main refrigeration systems, including our warehouse in California, use ammonia, a natural refrigerant with a Global Warming Potential (GWP) of zero. Since 2015 we have been an industry-leading partner of GreenChill, a voluntary partnership with the Environmental Protection Agency. As a partner we set ambitious emission-reduction goals, report emissions annually, work to improve our existing and future store refrigeration and HVAC equipment, all while working closely with our equipment suppliers. Over 100 ALDI stores have received GreenChill Platinum Certifications, the highest certification level, and the number of certified stores will continue to grow.
ALDI cares about advancing efficiency and reducing environmental impact among its facilities nationwide. In 2018 alone, our solar production prevented the release of CO2 emissions equal to those created by an average car driving across the United States 12,427 times, or 15.6 million pounds of coal being burned. Our use of clean, solar energy grew to include rooftop solar systems on nine distribution centers and 99 stores. We've also expanded solar projects across thirteen states.
At our California regional headquarters and warehouse, 8,208 solar panels were installed. The system powers approximately 70 percent of the warehouse’s utilities. All of our stores within California with viable roofs will have solar panels.
ALDI continues to pursue projects aimed at minimizing our carbon emissions and impact on the environment. Our renewable energy portfolio continues to remain an important piece of that strategy in making long-term improvements.
