Investors are concerned that Kroger's globally significant carbon emissions are not being adequately addressed. One meaningful way Kroger could reduce its carbon footprint is to expand its use of renewable energy. While making some inroads on energy and supply chain efficiency, Kroger has not instituted programs to reduce the carbon impact of its power sourcing. Kroger's failure to meaningfully invest in renewable energy is in strong contrast to its peers, which are rapidly and profitably scaling renewable energy. Competitor Walmart installed 145 MW of solar at 364 different sites; Target developed 147 MW of solar at 300 sites, and Costco 51 MW. (Solar Means Business 2016, SEIA). Walmart has further committed to 100% renewable electricity, joining other major companies such as Whole Foods Market, IKEA, GM, and Starbucks. (RE100). Target has announced an ambitious goal to install distributed solar power on 500 more stores and distribution centers by 2020.
