Coca-Cola's factory in Kent, England, is an example of how the company is reducing emissions and water and energy use while rewarding employee initiative, Jessica Shankleman writes. The company's efforts are a mix of the practical and the idealistic, says John Burton of Coca-Cola. "It's the right thing to do. ... But there's also a benefit for us: If we're not using as much water, we don't have to buy it. It reduces our utility bills," he says.
