Walmart’s May 2019 ESG report put two climate measures side by side. The company said its own annual Scopes 1 and 2 emissions fell 6.1% in 2017 from 2015. Separately, suppliers reported avoiding more than 93 million metric tons over the prior two years through Project Gigaton. One is Walmart’s reported operational change; the other is supplier-reported progress across collective value chains. [shared-decd3831d01b3687cc0983c4c2ca45b663916ab259380b388d1122c6cf116557]
Launched in 2017, Project Gigaton invited suppliers to help avoid one billion metric tons by 2030. Walmart’s purchasing relationship may give suppliers reason to respond. The report also said renewable sources supplied 28% of Walmart’s electricity needs, against a 50% target for 2025. These are historical company-reported figures and ambitions, not current measurements or proof the targets were met. [shared-decd3831d01b3687cc0983c4c2ca45b663916ab259380b388d1122c6cf116557]
The competitive question is whether participation produces comparable, verifiable changes or mainly a broad tally of reported activity. The announcement does not establish supplier-level costs, independent checking, or whether smaller suppliers could respond on equal terms. Better evidence would separate measured reductions from avoided-emissions estimates and show who bears the expense. Without it, the target signals direction, not demonstrated climate impact.
