Green Apple
For numerous years, Apple has made a concerted effort to be more transparent about the steps they are taking to protect the environment.
The new Macbook from Apple have been designed to be the not only the greenest notebook Apple ever produced, but the greenest family of notebooks.
Every new MacBook has been built using materials that are highly recyclable and free of many of the harmful substances present in other computers. Apple engineers also designed the software and hardware to work together, in order to maximize energy efficiency and minimize the carbon footprint of the MacBook. Even the packaging was reconsidered and reduced, producing smaller boxes to ship and less material to recycle. 
Many harmful toxins eliminated
Apple has worked hard to eliminate many of the toxins that are a common part of notebook manufacturing. Take, for example, the mercury used in CCFL backlights and the arsenic contained in the glass of traditional LCD displays. Apple engineers removed both by choosing mercury-free LED technology and arsenic-free glass. They have also removed brominated flame retardants (BFRs) and polyvinyl chloride (PVC) from circuit boards, internal cables, connectors, insulators, shock mounts, adhesives, and more.
Highly recyclable
The MacBook precision unibody enclosure is formed from a single piece of solid, recyclable aluminium, replacing dozens of extraneous parts. The display is made of recyclable glass. Both materials are very desirable to recyclers, which means the raw materials used in the new MacBook computers can be reused in other products.
Longer-lasting battery in 17-inch MacBook Pro
The removable batteries in most notebooks are designed to be replaced every year or two, which means lots of batteries are used up and discarded. But the battery in the new 17-inch MacBook Pro lasts up to five years — or 1000 recharges. So it uses just one battery in the same time a typical notebook uses three.*
Reduced packaging
The new MacBook packaging is up to 41 percent smaller than the previous generation. And smaller boxes are much better for the planet. Because smaller boxes mean more boxes can be fitted on each shipping pallet — up to 25 percent more. Which means more products will fit on each boat and plane. Which means fewer boats and planes are used, resulting in fewer CO2 emissions. It’s just one seemingly minor change. But it has a major positive impact on our environment.
More energy efficient 
Because Apple makes both the hardware and the software for the MacBook, they were able to design them to work together. This allows Apple to make a smarter product that uses less electricity, earning it ENERGY STAR certification. For instance, to reduce energy consumption, the MacBook hard drive spins down automatically when inactive. The MacBook also decides which processor — CPU or GPU — is best suited to efficiently perform a task. The processor even throttles down to save power between keystrokes as you type. The LED-backlit display in the MacBook is another feature that plays an important part in conserving energy, consuming 30 percent less power than conventional LCD displays. And the display is designed to dim when you enter a darkened room. Together, these adjustments make the MacBook family much more energy efficient. In fact the MacBook, can run on just one-quarter the power of a single lightbulb.

*Apple does not warrant the battery beyond Apple's one-year Limited Warranty. The battery has a limited number of charge cycles and may eventually need to be replaced by an Apple Service Provider. Battery life and charge cycles vary by use and settings. See www.apple.com/batteries for more information.
