According to Apple, the majority of their corporate greenhouse gas emissions derives from the transportation, production, use and recycling of their own products, including the iPhone. Apple minimises their greenhouse emissions by setting stringent design-related goals for material and energy efficiency. Over the life cycle of iPhone devices, about 50 per cent of the greenhouse gas emissions come from customer use. Over 40 per cent occurs during production, while the rest is caused during transport and recycling.
Apple attempts to restrict harmful substances from the iPhone devices and their packaging. All iPhones comply with the European RoHS Directive (Restriction of Hazardous Substances). Harmful materials including lead, mercury, cadmium, and brominated flame retardants are restricted by Apple. All iPhone devices use a mercury-free LCD display, bromine-free printed circuit boards, arsenic free glass and PVC-free headphones and USB cables.
