McLaughlin is responsible for ensuring that Walmart, the world’s largest company, meets its ambitious environmental goals. Those include deriving half its energy needs from renewable sources by 2025; reducing the chemical footprint of products like household cleaners; and getting suppliers to cut their greenhouse-gas emissions.
