Back in 2006, Steve Jobs announced that Apple would be building another campus. Fast forward eight years, and construction on the $5 billion project in Cupertino is underway. We've seen a few renderings of the project, and we know that the 2.8 million-square-foot campus will welcome 13,000 employees once completed, but some facts about the project have yet to be shared.

During Climate Week NYC, Tim Cook dropped a little knowledge about the space that would sound like a crazy and unreachable goal if the company he was speaking for weren't Apple. "We're building a new headquarters that will, I think, be the greenest building on the planet," quotes Gizmodo. "It'll be a center for innovation, and it's something clearly our employees want and we want." Cook didn't get into specifics of how Apple plans to claim that record, but the words alone were enough to excite the architectural and tech worlds, and now everyone will be watching the progress ever more closely.

The Co-Operative Group's headquarters in Manchester may be the current greenest building on the planet, but Apple's $5 billion initial budget is well over the £100 million that Co-Op spent on their building, so we shall see how this turns out.

While you wait, check out this cool drone video of the construction site where the "Spaceship" campus is being built:
