Watch Apple CEO Tim Cook Introduce Al Gore’s Sequel to ‘An Inconvenient Truth’

Apple CEO Tim Cook took the time to introduce the sequel to former Vice President Al Gore’s documentary film An Inconvenient Truth, according to Apple Insider on Thursday.

Titled An Inconvenient Sequel: Truth to Power, the still-unreleased picture was played for small, select crowd in Silicon Valley on Thursday, and a clip of Cook’s introduction was posted to YouTube (GOOGL) by prominent tech venture capitalist Steve Jurvetson.

The introduction by Tim Cook, CEO of Apple and a panel with Al Gore and my classmate Jeff Skoll, founder of Participant Media and catalyst of the filming,” Jurvetson wrote on his YouTube page. “Jeff also helped nudge Al Gore to turn his original powerpoint presentation into a documentary by Davis Guggenheim that had a huge influence on the public perception of climate change.”

An Inconvenient Sequel: Truth to Power had its world premiere at the Sundance Film Festival in Utah in January. Directed by Bonni Cohen and Jon Shenk, the film follows Gore’s speeches, travels, and interviews over the course of the year on the progression of climate change since the first documentary.

An Inconvenient Truth was released in 2006, and it went on to win two Academy Awards: Best Documentary Feature and Best Original Song (“I Need To Wake Up” by Melissa Etheridge)—making it the first documentary to win the latter award.

Gore is also an Apple board member.

Apple has been very vocal with its environmental agenda, with a goal to power 100% of its operations worldwide through renewable energy. Last March, the company said 93% of its worldwide facilities run on renewable energy.

Additionally, Apple’s vice president of environment Lisa Jackson has spoken about how the iPhone maker is pushing its suppliers to embrace clean energy. In September, Jackson announced that two more of the company’s iPhone parts suppliers—Solvay Specialty Polymers, a Belgian company making antenna bands; and Catcher Technology, a Chinese company producing aluminum parts—were planning to power 100% of their production for Apple with clean energy by 2018.

The tech giant is also preparing to start construction on a new $50 million data center, codenamed Project Isabel, at the company’s massive campus in Reno Technology Park. As Fortune‘s Kirsten Korosec reported in February, Northern Nevada—particularly the Reno-Sparks area on the western border—has become a hotspot for data centers thanks to an abundance of land as well as access to clean energy sources, like solar and geothermal.

Apple won permission in August 2016 from the federal government to sell excess electricity generated by three of its solar projects—two of which are in Nevada. The third is Apple’s Flats Solar project in central California.

Apple has made its commitment to the environment known in other ways. Last spring, Apple said it would donate all proceeds from certain app and in-app purchases to the World Wildlife Fund for a limited period of time.

In January 2017, Apple—along with Google and Facebook—topped environmental watchdog Greenpeace’s energy report card, with “As” across all five categories: energy transparency, renewable energy commitment and policy, energy efficiency and mitigation, renewable procurement, and advocacy.

An Inconvenient Sequel: Truth to Power is scheduled for a wide release on July 28.
