Washington, D.C. — As a
growing group of environmental leaders call
on Walmart to stop greenwashing and commit to real sustainability, a new study finds that Walmart is one of the nation's largest users of
coal - fired electricity, and that its heavy
reliance on dirty power pumps nearly 8 million metric tons of carbon pollution into the air each year.
China and the United States are responsible for nearly half the world's output of carbon gases, although many scientists say the Chinese share is larger and
growing at a rapid pace due to its
reliance on coal - fired power plants.
