President Donald Trump’s announcement on Thursday that the U.S. will withdraw from the Paris Climate Agreement phases out U.S. commitments to achieve carbon reduction targets and make financial contributions to slow climate change.
It was a move environmentalists found disappointing, at best. But Vanderbilt University law and earth science professors contend initiatives that reduce carbon emissions from corporations and households can fill some of the gap.
They point to the example of Walmart, which reduced carbon emissions worldwide by more than 20 million metric tons by focusing on efficiency in its global supply chain.
