Understanding Carbon Footprint of Smartphone

Introduction

Carbon footprint is a measure of the total amount of greenhouse gas emissions produced directly and indirectly by an individual, organization, or product. It includes carbon dioxide, methane, nitrous oxide, and other greenhouse gases that contribute to climate change.

The calculation of carbon footprint can vary depending on the entity being measured. Generally, it involves the identification and quantification of all greenhouse gas emissions produced during the life cycle of a product, service, or activity. This includes emissions from the extraction of raw materials, manufacturing, transportation, use, and disposal.

The impact of carbon footprint on climate change is significant, as greenhouse gas emissions trap heat in the Earth’s atmosphere and contribute to the warming of the planet. This can lead to more frequent and intense natural disasters, rising sea levels, and other detrimental impacts on the environment and human society.

Here are some general statistics on carbon footprint:

Global carbon emissions: In 2019, global carbon dioxide (CO2) emissions from energy use totaled 33.1 billion metric tons.
Per capita emissions: The average per capita carbon footprint in the world was 4.8 metric tons of CO2 in 2019. However, this varies greatly by country, with some countries having much higher or lower per capita emissions than others.
Industry emissions: The energy sector is the largest contributor to global carbon emissions, accounting for around 73% of emissions in 2019.
Transportation emissions: Transportation is the second-largest contributor to carbon emissions, accounting for around 16% of global emissions in 2019.
Building emissions: Buildings contribute to around 6% of global carbon emissions, primarily through energy use for heating, cooling, and lighting.
Impact on climate change: The Intergovernmental Panel on Climate Change (IPCC) has determined that in order to limit global warming to 1.5°C above pre-industrial levels and avoid the most catastrophic impacts of climate change, global carbon emissions must be reduced by around 45% from 2010 levels by 2030, and reach net-zero by around 2050.

Understanding the Carbon Footprint of Smartphone

Smartphones have become an integral part of our lives, but their environmental impact is often overlooked. From the manufacturing process to everyday usage, smartphones contribute significantly to carbon emissions and climate change. In this section, we will explore the carbon footprint of smartphones in detail and provide you with actionable strategies to reduce their environmental impact. Let’s dive in!

The carbon footprint of a smartphone refers to the total amount of greenhouse gas emissions it produces throughout its lifecycle. This includes not only the manufacturing process but also its usage and eventual disposal. The manufacturing phase, however, contributes the most to the carbon footprint of smartphones.

Researchers have found that smartphone manufacturing is responsible for a staggering amount of carbon emissions. The production of smartphones requires the extraction and processing of raw materials such as rare earth metals, which leads to deforestation, habitat destruction, and pollution. Additionally, the energy-intensive manufacturing process itself contributes to greenhouse gas emissions.

The production and disposal of plastic mobile covers contribute to greenhouse gas (GHG) emissions, exacerbating climate change. The extraction and refining of fossil fuels for plastic production, coupled with the energy-intensive manufacturing processes, result in substantial carbon dioxide (CO2) emissions. Additionally, plastic covers contribute to landfill emissions as they take hundreds of years to decompose. Switching to compostable and biodegradable materials can help reduce carbon emissions by minimizing the reliance on fossil fuels and enabling quicker decomposition.

According to the United Nations Environment Programme (UNEP), the global plastic industry is responsible for approximately 1.8 gigatons of CO2 emissions annually.
A study by the Center for International Environmental Law (CIEL) estimates that the plastic industry’s greenhouse gas emissions could reach 1.34 gigatons of CO2 equivalent per year by 2030, further contributing to climate change.

Manufacturing: The Major Source of Emissions

Extraction and Production: The life cycle of a smartphone begins with the extraction of raw materials, such as gold, cobalt, lithium, and other heavy metals. The mining of these materials is energy-intensive and often leads to environmental pollution. During the production process in mega factories, approximately 85%-95% of a smartphone’s carbon footprint is generated. The manufacturing of components, including batteries, integrated circuits, speakers, and screens, contributes to carbon emissions and environmental pollution.

Network Infrastructure: The software development and operation of smartphones’ operating systems, such as iOS and Android, rely on networking and data centers. These infrastructures consume significant amounts of energy, resulting in carbon and heat emissions. Data centers alone account for nearly 1% of global electricity demand, contributing to 0.3% of all global CO2 emissions.

Usage: While the production process contributes a substantial portion of a smartphone’s carbon emissions, its usage also leaves an environmental impact. Research suggests that an average of 63 kilograms of CO2 emissions is produced from just one hour of smartphone usage per day, for a year. With an increasing number of people becoming dependent on smartphones, the carbon emissions from their usage continue to rise.

EoL: The frequent upgrading of smartphones leads to a significant amount of electronic waste. In 2019 alone, the estimated weight of discarded smartphones reached over 50 million tonnes, accounting for approximately 10% of global e-waste. Proper recycling and disposal methods are crucial to mitigate the environmental consequences of e-waste.

In a recent publication, Mike Berners-Lee presents astounding research findings. According to his analysis, in the year 2020, the number of active mobile phones reached a staggering 7.7 billion, contributing to an approximate carbon dioxide equivalent footprint of 580 million tonnes. This amounts to roughly 1% of the total global emissions, and the trajectory indicates a further increase as smartphone adoption continues to grow.

In our fast-paced digital world, mobile phones have become an integral part of our lives and it isn’t easy to reduce the carbon footprint from the usage. Surprisingly, mobile phone accessories contribute astounding ~180 million kgs of carbon dioxide equivalent GHG per year. With the increasing demand for mobile devices, there is a growing concern about the environmental impact of their accessories, such as mobile covers. Traditional plastic covers contribute significantly to pollution and waste accumulation. This article explores the need for compostable and biodegradable mobile covers as an eco-friendly alternative. We will also delve into the alarming statistics surrounding carbon emissions and water footprints associated with conventional covers.
