Starbucks has calculated the carbon footprint of its North American locations only once, in 2003, when it had approximately 3,700 stores in North America, Forbes reports. It now has 6,281 U.S. company-owned stores and more than 1500 international locations.
At that time, Starbucks emitted 295,000 tons of carbon into the atmosphere. Starbucks decided to leave out an additional 81,000 tons of carbon dioxide it emitted by transporting coffee materials and disposing of solid waste.
That 295,000-ton figure gives Starbucks a small carbon footprint, among a list of about 1,000 companies compiled by the Carbon Disclosure Project. Near the top of the list is American Electric Power with 146.5 million tons of carbon emissions. Next in line are oil and gas companies Royal Dutch/Shell and British Petroleum with 105 million tons and 92 million tons.
Comparatively, General Electric’s 12.4 million ton footprint makes it a medium-size emitter. The smallest carbon emitters weighed in at a few thousand tons. Most of the lower footprints belong to insurance companies, retailers and banks.
The EPA asks companies to check their numbers annually. Both Intel and Sun Microsystems, for example, do just that.
