Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Apple to Honor Earth Day 2014 at Retail Stores, Main Campus
The company will color its logos in green for the occasion, as employees will wear special shirts with an event planned at Apple's headquarters at 1 Infinite Loop in Cupertino, California. Apple last celebrated Earth Day in 2006 by holding a free computer takeback program in honor of the event.
Apple has remained active in its environment efforts throughout the past few years, which include powering its data centers with 100% renewable energy, expanding its recycling program, and reporting on its carbon footprint. Last May, Apple also hired former Environmental Protection Agency chief Lisa Jackson to lead the company's environmental responsibility efforts.
Environmental activist group Greenpeace also featured Apple as a "green energy innovator" in its latest report earlier this month, praising the company for its commitment to renewable energy after taking issues with previous efforts.
