Walmart. outfitted more than 500 of its stores with low- and medium-temperature refrigerated
display cases and installed occupancy sensors and LED dimming capabilities to reduce the time
the LED refrigerated display cases were at 100 percent light levels (from 24 to 15 hours a day).
As a result of the changes, the company expected to realize a net 66 percent energy reduction
from its traditional lighting solution, save more than $2.6 million a year in energy costs, and cut
its carbon dioxide emissions by 35 million pounds.
By making the packaging just a little bit smaller on its Kid Connection product line, one of
Walmart’s private label toy brands, the company required 497 fewer containers to ship the
products, generating a freight savings of more than $2.4 million per year. The savings also
reduced the company’s environmental impact by more than 3,800 trees and saved more than
1,000 barrels of oil a year. (See Exhibit 13.)
When Walmart replaced produce packaging on just four products (cut fruit, herbs, strawberries,
and Brussels sprouts) with corn-based (PLA) packaging, the change saved the equivalent of
800,000 gallons of gasoline and prevented over 11 million pounds of greenhouse gas emissions.
Traditionally, Walmart bought rotisserie chickens in wax-coated cardboard boxes (which were
not recyclable). When the company switched to uncoated, recyclable corrugated cardboard,
Walmart realized a savings of $2.2 million dollars a year in the cost of packaging. It also
prevented 2.4 million cases from being put into a landfill and began generating approximately
$245,000 in annual income from the associated recycling. The change also resulted in an annual
savings of 1,700 trees.
By rightsizing display packaging for Shower Soothers, the company fit 21 “shippers” on a pallet
(instead of just three), reducing the number of trucks required to transport them to Walmart’s
stores from 196 to only 28. Additionally, the change reduced cost of goods sold by over a
quarter of a...
