The iPhone 7 is a smartphone designed, developed, and marketed by Apple Inc. Unless otherwise specified, data on this page refers to the 32GB model of the device which has life cycle greenhouse gas (GHG) emissions of 56 kg carbon dioxide equivalent (CO2e). The 128GB and 256GB devices have life cycle greenhouse gas emissions of 63 and 75 kg CO2e respectively. The developer estimates a service life of three years for this smartphone, which gives it an estimated yearly carbon footprint of about 19 kg CO2e for the 32 GB device.[1]

The principal source of information for this article is an environmental report published by Apple Inc.[1] Third-party verification of carbon emissions associated with company operations was obtained by Apple from Bureau Veritas, and calculations of downstream emissions related to the product were checked for quality and accuracy by the Fraunhofer Institute in Germany.[2]

Materials

The device is composed of a lithium-ion polymer battery (26 g), a LED-backlit display (25 g), aluminum (24 g), stainless steel (23 g), arsenic-free glass (16 g), circuit boards (11 g), non-PVC plastic (7 g), and other materials (6 g). The materials data for this product does not include the charger hardware packaged with the device. The manufacturer states that the devices comply with the Restriction of Hazardous Substances Directive (RoHS). This directive limits the amount of lead, mercury, cadmium, hexavalent chromium, and brominated flame retardants PBB and PBDE that can be present in the product. Emission information specific to materials was not provided by the manufacturer, but is included in the production statistics.[1]

Production

The devices are manufactured by Hon Hai Precision Industry Co. Ltd which is also known as Foxconn.[3] Production of each device emits 44 kg CO2e or 78% of life cycle emissions from this product. This includes the extraction, production, and transport of raw materials for the device and product packaging.[1]

Packaging

The product retail packaging consists of approximately 97%(165 g) fiber and 3%(5 g) plastic. The fiber includes sustainably managed forests, bamboo, and waste sugarcane. The company states that the packaging is highly recyclable. The product packaging emissions are included in the production statistics.[1]

Distribution

Distribution accounts for 3% of the device’s greenhouse gas emissions or 2 kg CO2e. Apple has included, in these measurements, air and sea transport from the manufacturing site to regional distribution hubs and from the distribution hubs to the end consumer.[1]

Usage

Consumer usage of the iPhone 7 accounts for 18% (10 kg CO2e) of the greenhouse gas emissions during the device’s life. This is based on three years of electricity usage by the first owner of the device. This does not include any accessories purchased by the user, such as cases, screen protectors, or chargers. Additionally, many products are resold after the first user, and use by subsequent users is not included in this emission data.[1]

End of Life

The service life of an iPhone is estimated by Apple to be three years. Apple Inc. offers recycling programs in 99% of countries where the products are sold.[1] Depending on the condition of the device the product may be recycled or resold. The product resale program is operated by Brightstar who refurbishes and resells 95% of devices they recycle. The remaining five percent of devices that can not be economically repaired are recycled for their raw materials.[4] The transportation to recycling centers and energy used during the separation and shredding of components is 1% (0.6 kg CO2e) of the life cycle greenhouse gas emissions.[1]
