What is a digital carbon footprint?
A digital carbon footprint refers to the environmental impact of digital technologies and online activities, including the emission of greenhouse gases (GHGs) and energy consumption associated with the use and operation of digital devices, networks, and services. It encompasses the carbon emissions generated throughout the lifecycle of digital technologies, from manufacturing and distribution to use and disposal.
Everything we do online or on our digital devices is part of that footprint, or impact, on the environment. According to Plan Be Eco:
If you use a streaming service on your TV for one or two hours a day every year, you use enough electricity to run your fridge for half a year.
Netflix’s carbon footprint was 1.1 million MT in 2020, equivalent to a city with 150,000 homes.
TikTok has the largest carbon footprint among social media applications. It emits as much as 2.63 grams of CO2 equivalent per minute of each active user. The number of registered accounts there has already exceeded one billion, so it generates huge carbon emissions.
It’s not just electricity usage that matters, either, especially when it comes to the carbon footprint of organizations. Water usage in the data center is a concern, and organizations are looking for smart ways to reduce both power and water consumption. They also need ways to reduce e-waste, which consists of electronic devices and other hardware, which contain toxic chemicals and hazardous materials that can leach into groundwater and soil.
Internet pollution and carbon emissions from data centers must be reduced because the carbon footprint of digital technologies, if left unchecked, could lead to serious environmental challenges.

Continually measure and monitor - Implement tools and systems to measure and monitor energy usage, carbon emissions, and overall environmental impact. Set targets and regularly assess progress to identify areas for improvement.
The environmental impact of computing
While computers have brought tremendous positive advancements to various aspects of life and business, these benefits are not without consequences. As of 2021, experts estimated the existence of approximately 7.2 million data centers worldwide. These data centers play a crucial role in meeting the extensive computing requirements of businesses, facilitating operations such as data storage, backup, networking, email services, website hosting, and more.
The sheer number of data centers poses a significant concern in terms of power consumption. Data centers vary in size, with many being massive facilities housing thousands or even tens of thousands of servers that consume electricity voraciously. The International Energy Agency has estimated that global data centers consume approximately 200 terawatt-hours (TWh) of electricity annually, accounting for nearly 1% of the world's total electricity demand.
Given the rising energy costs associated with data centers and the growing regulatory focus on environmental issues, organizations are faced with the challenge of finding greener and more sustainable operational approaches. Cloud storage, which heavily relies on vast data centers managed by hyperscalers, has a considerable environmental impact. The sustainability of cloud services hinges on the industry's efforts to develop and adopt more energy-efficient operational practices.
What is corporate digital responsibility?
Corporate digital responsibility refers to a company's commitment to conducting its digital operations in an ethical, responsible, and sustainable manner. It encompasses the company's actions and practices related to the use of digital technologies, data privacy, cybersecurity, environmental impact, and societal considerations. Corporate digital responsibility extends beyond legal compliance and encompasses proactive efforts to address social and environmental concerns associated with digital activities.
What is carbon net zero?
Carbon net zero, also known as net zero emissions or carbon neutrality, refers to the state in which a balance between greenhouse gas emissions produced and greenhouse gas emissions removed or offset is achieved. It means that the net amount of carbon dioxide (CO2) and other greenhouse gases released into the atmosphere is zero or effectively zero. Reduction measures include decarbonization, the use of clean energy sources, implementing energy-saving devices, and cutting down on resource usage in general.
Countries around the world are pledging to eliminate manmade greenhouse gases through reduction measures to bring the Earth’s atmosphere into balance again and stop climate change. Some nations, such as France, are aiming to be carbon-neutral by 2030, while others, such as the United States, are looking toward 2050 for that goal.
What is digital decarbonization?
Digital decarbonization is the process of reducing the carbon emissions and environmental impact associated with digital technologies and digital activities. It involves adopting sustainable practices, improving energy efficiency, and implementing environmentally friendly measures throughout the lifecycle of digital technologies, including their production, usage, and disposal. Furthermore, digital technologies themselves can contribute to this endeavor. For instance, digital communications, data analytics, and system automation software are helping power companies operate electrical grids much more efficiently.
How to reduce energy consumption in data centers
