Walmart Shipping of crap adds MUCH to pollution but DO NOT report it. Why not?

A decade ago, Walmart began promoting itself as a sustainability leader. And, yet, in all the years since, the company has been silent about the environmental impacts of its massive shipping operations. It’s as though this core part of its business doesn’t exist. In fact, when Walmart reports its greenhouse gas emissions each year, it omits the pollution generated by shipping.

That could change on Friday. Shareholders will consider a resolution that would require the company’s management to report greenhouse gas emissions from shipping and take concrete steps to reduce them, as other larger retailers have done. The resolution was proposed by Mary Pat Tifft, a member of Our Walmart, a growing organization of Walmart employees that has won significant improvements in the company’s labor practices and is increasingly focusing on its environmental impact.
