What You'll Learn
Manufacturing
Mining for rare earth metals, which are often refined in rural China, can pollute the environment and harm local communities. For example, a report by the BBC detailed the impacts of mining operations in Inner Mongolia, describing a lake of toxic sludge, a constant smell of sulphur, and water turned black by coal dust.
In addition to the environmental impact, the iPhone manufacturing process has also been associated with human costs. A report from Motherboard detailed how, in Bolivia, over 15,000 workers, some as young as six years old, enter dangerous mines to extract tin, lead, and zinc, all used in iPhone production.
Apple has taken steps to reduce the use of toxic and hard-to-source materials, such as using 100% certified recycled cobalt and over 95% recycled lithium in iPhone batteries. However, their environmental reports show a trend of rising carbon emissions associated with their most popular phones. Apple has also been criticized for its wasteful use of raw materials, opposition to right-to-repair laws, and the amount of e-waste created by its products.
To reduce their environmental impact, Apple has implemented initiatives such as partnering with solar energy developers, introducing a robotic disassembler for recycling iPhones, and phasing out harmful chemicals in manufacturing. While these efforts are positive, they are contrasted by Apple's aggressive product launch cycle, raising doubts about the company's environmental commitment.

Mining
The specific minerals obtained through mining that are used in iPhones include silicon, copper, cobalt, tin, gold, lithium, silver, aluminium, and rare earth elements such as neodymium, europium, and cerium. These minerals are essential for various components of the iPhone, including microchips, wiring, batteries, and screens.
The mining process has been associated with labour abuses and unsafe working conditions. In some cases, children have been reported to work in mines, and the average lifespan of miners in certain locations is reduced. The dust and chemicals created and used during the mining process can also be harmful to the health of miners and surrounding communities.
While Apple has set ambitious goals to transition away from mining and towards using recycled materials, the details of how this will be achieved are still unclear. In the meantime, Apple has implemented measures such as using robots to efficiently disassemble iPhones for recycling and congratulating suppliers for using renewable energy sources. However, critics argue that Apple could do more by making their products easier to repair and extending their lifespan.
Overall, the mining stage of an iPhone's life cycle has significant environmental and social impacts that need to be addressed to make the production process more sustainable and ethical.

Transportation
The iPhone's transportation phase accounts for a relatively small portion of its total carbon emissions. Estimates vary, but it is generally agreed that transportation makes up a maximum of 2% of the iPhone's overall carbon footprint. This is significantly lower than the emissions generated during the production and manufacturing stages, which account for the majority of the iPhone's carbon emissions.
However, it is important to note that transportation emissions are not limited to the movement of the final product. The transportation of raw materials and components to the manufacturing sites also contributes to the iPhone's carbon footprint. This includes the extraction and production of these materials, which may involve further transportation emissions.
The iPhone's transportation to the consumer also plays a role in its carbon footprint. Once the iPhones reach distribution centres, they are then transported to storefronts and retail locations, adding to the overall transportation emissions. This stage involves road transportation, with trucks and other vehicles used to distribute the iPhones to stores worldwide.
Additionally, the end-of-life transportation of iPhones, although a small percentage, should be considered. When iPhones reach the end of their lifespan, they are transported from collection points to recycling sites, contributing to their overall carbon footprint. This stage involves the transportation of electronic waste (e-waste) and is an important part of the iPhone's life cycle, especially with the increasing focus on recycling and sustainability initiatives.

Usage
The usage stage of an iPhone's lifecycle is responsible for a notable proportion of its overall carbon footprint. According to Apple, product use accounts for 18% of the total carbon footprint over the iPhone's life cycle, which is estimated to be around 3 to 4 years.
However, Greenly experts estimate that Apple is missing 80% of the iPhone's total climate impact from its calculations. They argue that mobile data usage should be factored into the equation, suggesting that an additional 50 kg of carbon emissions should be included in the iPhone 13's total carbon footprint. This would bring the total footprint closer to 114 kg of CO2e, with usage contributing a significant proportion of this figure.
The frequent release of new iPhone models by Apple contributes to a culture of frequent upgrades, with millions of users choosing to replace their phones each year. This short lifespan of iPhones leads to increased electronic waste and consumption of resources. Apple has been criticised for its aggressive product launch cycle, with each new release enticing tens of millions of people worldwide to upgrade, even if the changes are relatively minor.
To reduce the environmental impact of iPhone usage, consumers can play a crucial role by extending the life of their devices, repairing instead of replacing, and trading in responsibly when upgrading. By keeping their iPhones for longer, users can help reduce electronic waste and decrease the demand for new devices.
Overall, while the usage stage of an iPhone's lifecycle is a significant contributor to its carbon footprint, the frequent release of new models and short lifespan of devices are also important factors that contribute to the overall environmental impact.

End-of-life
The end-of-life stage of an iPhone's lifecycle is when the device is disposed of or recycled. This stage contributes to the carbon footprint of an iPhone, although it is a relatively small proportion compared to other stages such as manufacturing and transportation.
The carbon footprint of an iPhone includes emissions from mining resources, distributing devices, consumer use, and end-of-life processes. While consumer use typically accounts for a significant proportion of an iPhone's carbon footprint, the end-of-life stage has a smaller impact, estimated at less than 1% of emissions by some sources. These end-of-life emissions include transportation from collection points to recycling sites and the energy required for recycling processes such as separating and shredding materials.
When iPhones reach the end of their lifespan and are disposed of in landfills, they contribute to pollution by releasing toxins that contaminate water and soil. This improper disposal of electronic waste, or e-waste, has severe environmental consequences. In some cases, iPhones may be refurbished and resold in developing nations, but these countries often lack modern recycling methods for effectively handling the glass, chips, wires, and plastics that make up smartphones. As a result, informal recycling practices can cause more harm to the environment than good.
The release of toxins during the end-of-life stage of iPhones is a significant concern. In villages near Guangzhou, plastics from iPhones may be melted in primitive conditions, releasing harmful substances into the air. Metals may be melted in clay ovens without adequate environmental protections, and makeshift smelters may create bullion of copper and aluminum for resale. The wires and circuit boards from iPhones often end up in places like Guiyu, China, where they are burned over coal fires to recover valuable materials, leading to severe pollution of air, water, and soil.
To reduce the environmental impact of iPhones at the end of their lifespan, proper recycling practices and extended device use should be encouraged. Apple has introduced initiatives to improve its environmental sustainability, but the frequent release of new iPhone models raises questions about the company's commitment to reducing its carbon footprint.
