For almost two years, Apple Inc. ’s efforts to go green have been the responsibility of Lisa Jackson, who was hired to oversee the company’s sustainability initiatives after she stepped down as head of the Environmental Protection Agency.

She sat down with Jeffrey Ball, contributing editor at The Wall Street Journal and scholar-in-residence at Stanford University’s Steyer-Taylor Center for Energy Policy and Finance, to discuss Apple’s commitment to renewable energy and why a recently announced solar deal is a good one for shareholders.

Apple is one of the few companies that is transparent about its environmental commitment. Sadly, this is the reason that the press goes after Apple more than other companies—Apple makes all the information available, while the others hide it.
