Lisa Jackson on designing the iPhone with the environment in mind

"We strongly believe that if what we do matters, it should show up in our products," said Lisa Jackson, head of sustainability at Apple and former administrator of the U.S. Environmental Protection Agency. 

Beyond the new iPhone 8 and iPhone X's design for great user experience, the new products were created with the environment in mind. 

"We set about focusing on the carbon intensity of aluminum," she said, for example, by cutting down on waste, increasing renewable energy and using hydro-powered smelting. As a result, the carbon intensity of the iPhone 8 is 11 percent less GHG per gram than the iPhone 7 and 83 percent less than the iPhone 6. 

The company's other planet-minded decisions were to use smaller, efficient packaging and engage some of its packaging suppliers in committing to source 100 percent renewable power. 

Jackson also talks about Apple's commitments on renewable energy, circular materials and how she views the current EPA.
