Just ahead of Earth Day, Apple has released a new ad and overhauled a section on its website designed to highlight its environmental initiatives, including the shrinking of its carbon footprint and the reduction of toxins and energy use in its products. The nearly two-minute-long video is narrated by none other than Apple CEO Tim Cook, who explains how the company has been aggressively shifting over to renewable energy. Under Cook, Apple has increasingly drawn focus to its environmental initiatives, and it appears that its now pushing toward being seen as a real leader on sustainability. The overhauled environment section on Apples website now resembles a page advertising a new product more than a corporate initiative, with different sections breaking down the ways that Apple says its making progress.
