Environmental Report
Apple and the Environment
Apple believes that improving the environmental performance of our business
starts with our products. The careful environmental management of our products
throughout their life cycles includes controlling the quantity and type of materials
used in their manufacture, improving their energy efficiency, and designing them for
better recyclability. The information below details the environmental performance
of the 15-inch MacBook Proas it relates to climate change, energy efficiency, material
efficiency, and restricted substances.

Climate Change
Greenhouse gas emissions have an impact on the planet’s balance of land, ocean,
and air temperature. Most of Apple’s corporate greenhouse gas emissions come from
the production, transport, use, and recycling of its products. Apple seeks to minimize
greenhouse gas emissions by setting stringent design-related goals for material and
energy efficiency. The chart below provides the estimated greenhouse gas emissions
for the 15-inch MacBook Pro over its life cycle.

Energy Efficiency
Because one of the largest portions of product-related greenhouse gas emissions results from
its use, energy efficiency is a key part of each product’s design. Apple products use power-
efficient components and software that intelligently powers them down during periods of
inactivity. The result is that the MacBook Pro is energy efficient right out of the box.

The 15-inch MacBook Pro outperforms the stringent requirements of the ENERGY STAR
Program Requirements for Computers Version 5.2. Designed to be even more efficient
than previous models, it consumes 46 percent less energy than the original 15-inch
MacBook Pro. The following table details the power consumed in different use modes:
