Walmart pledges zero emissions by 2040
Walmart (WMT) on Monday announced a new set of sustainability goals, including a pledge to reach zero emissions by 2040. The news came ahead of the company’s Sustainability Milestone Summit, and as part of Climate Week NYC. The company says that about 29% of its operations are fueled by renewables and it diverts about 80% of its waste from landfills and incineration globally. Walmart CEO Doug McMillon said in a statement, “The commitments we’re making today not only aim to decarbonize Walmart’s global operations, they also put us on the path to becoming a regenerative company...” Earlier this month, Walmart and France-based Schneider Electric (SBGSF) announced a collaboration to increase access to renewable energy for Walmart’s U.S.-based suppliers. The Gigaton PPA Program aims to educate Walmart suppliers about renewable energy purchases and accelerate renewable energy adoption by participating suppliers through aggregate power purchase agreements.

E&E News reports that the death last week of Supreme Court Justice Ruth Bader Ginsburg could affect America's bedrock environmental laws, “leaving a chasm on the bench where once sat an environmental champion.” Ginsburg, the report notes, played a critical role in opening courtroom doors to green groups and established broad interpretations of the Clean Air Act, Clean Water Act and other laws.
Price tag per ton of carbon: $100,000
Two geoscientists and a philosopher from the University of Chicago estimate an “ultimate cost of carbon” to humanity at $100,000 per ton of carbon — a thousand times higher than the $100 or less routinely calculated for the cost to our generation. University of Chicago News reports the study, published in the journal Climactic Change, shows the economic “social cost of carbon,” pioneered by UChicago Prof. Michael Greenstone, is a number that is intended to represent the value of all future damages to our generation in today’s dollars. It calculates the difference between realistic projections of the economy with and without climate change, which typically comes out to $100 or less per ton.
