Mary Barra, chair and CEO of General Motors, says that electric vehicles are the future for the company and the automobile industry. GM has said it will phase out vehicles using internal combustion engines by 2035 and go carbon neutral at all of its facilities. Barra describes how she's executing on that plan as well as offering broader leadership lessons in an interview with HBR editor Amy Bernstein.

Mary Barra is a GM insider, but she's also a change agent who will continue the company's aggressive comeback.
