Walmart’s sustainability efforts aim to protect and restore nature and reduce waste and emissions. Our focus on climate, nature, waste and people in supply chains has strengthened our business and communities in measurable ways. In 2019, Walmart bought more wind and installed more solar than any other company in the U.S., according to solar and wind associations, and in 2020, we diverted 81% of our waste from landfills and incineration globally. We also made climate disclosure nonprofit CDP’s ‘A List’ for climate action in 2019 and 2020.
