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 e ciency, and designing them for better recyclability. The information below details the environmental performance of the 24-inch iMac as it relates to climate change, energy e ciency, restricted substances, and material e ciency.
Model MB418, MB419, MB420 (24-inch iMac) Date introduced March 3, 2009

Climate Change

Greenhouse gas emissions have an impact on the planets balance of land, ocean, and air temperature. Most of Apples 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 e ciency. The chart below provides the estimated greenhouse gas emissions for the 24-inch iMac over its life cycle. Greenhouse Gas Emissions for 24-inch iMac
Recycling, 1% Transport, 5%
24-inch iMac is designed with the following features to reduce environmental impact: Arsenic-free display glass Brominated ame retardantfree PVC-free internal cables Highly recyclable aluminum and glass enclosure Meets ENERGY STAR Version 5.0 requirements. 24-inch iMac achieved a Gold rating from EPEAT.

Production, 37%

Customer use, 57%
Total greenhouse gas emissions: 1380 kg CO2e

Energy E ciency

Because the largest portion of product related greenhouse gas emissions result from its use, energy efficiency is a key part of each products design. Apple products use power e cient components and software that intelligently powers them down during periods of inactivity. The result is that the iMac is energy e cient right out of the box. The 24-inch iMac outperforms the stringent requirements of ENERGY STAR Program Requirements for Computers Version 5.0, months ahead of its e ective date. It consumes 27 percent less power in sleep mode and has an 8 percent smaller carbon footprint than the previous generation 24-inch iMac. The following table details the power consumed in di erent use modes. Power Consumption for 24-inch iMac

Material E ciency

Apples ultra-compact product and packaging designs lead the industry in material e ciency. Reducing the material footprint of a product helps maximize shipping e ciency. It also helps reduce energy consumed during production and material waste generated at the end of the products life. The enclosure of the 24-inch iMac is made of highly recyclable aluminum and glass. The chart below details the materials used in this model. Material Use for 24-inch iMac
Aluminum and steel, 3800g Others, 230g Power supply, 480g Circuit boards, 510g Hard drive and optical drive, 800g

Glass, 860g

Display, 2690g

Plastic, 1930g

Packaging The packaging for the 24-inch iMac is almost entirely recyclable and its retail box is made with a minimum of 25 percent post-consumer recycled content. In addition, its packaging is extremely material e cient, allowing more units to ship per pallet. The following table details the materials used in its packaging.

Restricted Substances

Apple has long taken the lead in restricting harmful substances from its products and packaging. As part of this strategy, all Apple products comply with the strict European Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, also known as the RoHS Directive. Examples of materials restricted by RoHS include lead, mercury, cadmium, hexavalent chromium, and PBB and PBDE brominated ame retardants (BFRs). The 24-inch iMac goes even further than the requirements of the RoHS Directive by incorporating the following more aggressive restrictions: Arsenic-free display glass Brominated ame retardant (BFR)free All internal cables free of polyvinyl chloride (PVC)

Recycling

Through ultra-e cient design and use of highly recyclable materials, Apple has minimized material waste at the products end of life. In addition, Apple o ers and participates in various product take-back and recycling programs in 95 percent of the regions where Apple products are sold. All products are processed in the country or region in which they are collected. For more information on how to take advantage of these programs, visit www.apple.com/environment/recycling/.

Electronic Product Environmental Assessment Tool (EPEAT): A program that ranks computers and displays based on environmental attributes in accordance with IEEE 1680. For more information visit www.epeat.net. Greenhouse gas emissions: Estimated emissions are calculated in accordance with guidelines and requirements as specied by ISO 14040 and ISO 14044. Calculation includes emissions from the following life cycle phases contributing to Global Warming Potential (GWP 100 years) in CO2 equivalency factors (CO2e): Production: Includes the extraction, production, and transport of raw materials and the manufacture of the product, as well as product packaging. Transport: Includes air and sea transportation of the nished product and its associated packaging from the manufacturing site to continental distribution hubs. Transport of products from distribution hubs to the end customer is not included. Use: User power consumption assumes a four-year period. Consumption patterns are modeled according to European Commission and U.S. Environmental Protection Agency computer eco-design studies. Geographic di erences in the power grid mix have been accounted for at a continental level. Recycling: Includes transportation from collection hubs to recycling centers, and the energy used in mechanical separation and shredding of parts. Energy e ciency terms: The energy values in this report are based on the ENERGY STAR Program Requirements for Computers Version 5.0. For more information, visit www.energystar.gov. O : Lowest power mode of the system when it is shut down. Also referred to as Standby. IdleDisplay on: System is on and has completed loading Mac OS X; the display set to its full brightness. IdleDisplay o : System is on and has completed loading Mac OS X; the display set to sleep. Sleep: Low power state that is entered automatically after 10 minutes of inactivity (default), or by selecting Sleep from the Apple menu. Wake-on-LAN is enabled. Power Supply E ciency: Average of the power supplys measured e ciency when tested at 100 percent, 50 percent, and 20 percent of the power supplys output power. Restricted substances: Apple denes a material as BFR-free and PVC-free if it contains less than 900 parts per million (ppm) of bromine and chlorine.
