Apple has lately become more vocal about its efforts to reduce the company's effect on the environment. On Monday, the company launched a website that highlights its progress and discloses some new efforts as well. The new site coincides with Earth Day and announces Apple's lofty goal: "We want to leave the world better than we found it."

"Better," says Apple CEO Tim Cook in the video. "It's a powerful word. And a powerful idea. It makes us look at the world and want more than anything to change it for the better."

The new site expands the scope and detail in terms of efforts to reduce harmful materials in its products and progress toward using only renewable energy at its facilities.

According to the new website, Apple's data centers now run on 100% renewable energy. And across all Apple facilities, the company uses 94% renewable energy, up from 35% in 2010.

The company also disclosed that it's in the process of expanding its product recycling program. Instead of just throwing out old gadgets, Apple users can currently return any product by printing out a label from the Apple website and shipping it back to the company.

Soon, users will simply be able to take any product back to an Apple store for disposal.
