Your Apple Messages Are Powered By Renewable Energy by Don Reisinger @FortuneMagazine April 22, 2016, 10:15 AM EDT E-mail Tweet Facebook Linkedin Share icons All of the Apple iMessages you send from your iPhone or Mac are powered by renewable energy, Apple says in a new ad launched for Earth Day. In an ad titled “iMessage—Renewable Energy,” Apple AAPL explains how whenever a person sends a message, including text and emojis, to another person via iMessage, they run through the company’s data centers. The iMessages are then directed to the recipient from Apple’s data center. “Every time you type ‘what’s up’, it makes its way here: to an Apple datacenter,” the company says in the ad, which combines graphics and text to make its point. Apple added that all of its data centers are completely powered by renewable energy, including solar and wind. “Which means every time you send [a heart emoji], you’re showing love for the [globe],” Apple said to cap off its ad.

Apple’s ad launched late on Thursday, just in time for Earth Day on April 22, a global event aimed at raising awareness for green initiatives and environmental friendliness. The tech giant has gone out of its way in recent weeks to illustrate its environmental friendliness. At its “Let Us Loop You In” press event last month, Lisa Jackson, Apple’s vice president of the environment and policy initiatives, noted that 93% of Apple’s worldwide facilities are running on renewable energy. The Cupertino, Calif.-based company has reached 100% renewable energy status in 23 counties, including the United States. Meanwhile, Jackson touted that 99% of all Apple’s product packaging is now sourced from recycled paper or sourced from a sustainably managed materials. Jackson also unveiled Liam, a robot that Apple uses to deconstruct its recycled devices. The idea behind Liam—and the Apple Renew program—is to get as much out of its recycled products as possible so those materials can be reused in the supply chain. Those materials can range from heavy metals to internal components. In February, Apple announced that it had issued $1.5 billion in bonds designated to fund clean energy products. It’s the largest environmental bond ever issued by a U.S. corporation, Apple boasted. All the while, Apple is working on a sprawling new campus in Cupertino that it’s set to move into next year. The campus, which will span 2.8 million square feet of office space to house 12,000 Apple employees, will include 700,000 square feet of solar panels and more than 7,000 trees when completed.

Apple has also revised its homepage with a “Happy Earth Day” message and details about some of the programs it’s instituted to help the environment.
