Walmart’s Dirty Energy Secret: How the Company’s Slick Greenwashing Hides its Massive Coal Consumption

By Stacy Mitchell and Walter Wuthmann - Institute for Local Self reliance, November 2014

In October 2014, at an event broadcast live from Walmart’s Arkansas headquarters, the company’s top executives took the stage to extol its environmental leadership. The announcements they made that day would be covered widely by the press, including the Boston Globe, Guardian, and New York Times.

The event opened with a video listing Walmart’s achievements over the preceding months: “We signed our largest multi-state solar power purchase agreement,” the narrator says, over a shot of workers installing new, glossy solar panels. “We were recognized by President Obama for announcing that we will double the number of on-site solar energy projects.” Then Walmart’s CEO, Doug McMillon, and its vice president of sustainability, Manuel Gomez, addressed the crowd. “You get one point for launching a goal,” said Gomez, “and nine points for execution... and what you saw in the video is exactly what we’re doing: executing against these goals.”

But off the stage and out in the real world, Walmart’s sustainability initiatives are heavy on admiration-inducing goals and astonishingly light on execution. Nearly a decade ago, the company pledged to shift to 100 percent renewable energy and acknowledged its responsibility to reduce its climate emissions as quickly as possible. Today, however, Walmart remains as deeply committed as ever to the dirtiest fuels, especially coal. It derives only 3 percent of its U.S. electricity from its renewable energy projects, down from 4 percent two years ago.

In this first-of-its-kind analysis, ILSR provides new information about Walmart’s energy mix and environmental footprint. We calculate the total electricity use, coal-fired power consumption, and resulting carbon emissions of every Walmart store and distribution center in the country in 2013. We also evaluate the company’s renewable energy projects, finding that they are too small and located in the wrong places to have much of an impact on Walmart’s coal use and climate emissions.

Our analysis finds that Walmart’s electricity consumption entails burning a staggering amount of coal: 4.2 million tons a year. That’s enough to give every kid in America a stocking filled with 126 pounds of the sooty stuff as a holiday present. Or, to measure it another way: If you dumped coal on a football field, you’d have to pile it 35 feet high, from end-zone to end-zone, just to power Walmart’s U.S. stores for one week. Walmart sources more of its electricity from coal (40 percent) than the U.S. as a whole (39 percent) — a remarkable fact for a company that has touted its environmental responsibility for years. Indeed, we find that Walmart alone consumes 0.5 percent of all the electricity produced from coal in U.S., a stunning figure given the size of the entire national economy and population.
