The internet consumes a lot of electricity, and digital technologies account for around 4% of global carbon emissions. This is due to the energy required to power the vast network of physical infrastructure that enables data transfer and storage. Data centres, which serve as factories of the information age, are the main contributors to this energy consumption. They require a lot of electricity and air conditioning to keep the servers running 24/7. While individual messages, emails, and internet searches don't produce a significant carbon footprint, the cumulative effect of billions of people performing these actions online contributes to digital pollution. To avoid pollution through the internet, individuals can take steps such as deleting unnecessary emails and files, reducing video streaming, limiting screen time, and upgrading equipment less often. Additionally, choosing low-energy consumption products and favouring repair over substitution can also help reduce digital pollution.

Reduce online video consumption
The manufacture of digital devices and their subsequent energy consumption are significant contributors to digital pollution. Streaming is one of the biggest consumers of energy in terms of internet usage, with the transfer of real-time data for videos viewed in high definition generating high energy consumption.
To reduce online video consumption, it is important to limit streaming and watch fewer videos. This can be achieved by opting for downloads over streaming, as streaming services such as Netflix, Amazon Prime, and YouTube account for a significant portion of the video streaming carbon footprint. Watching low-definition videos also saves bandwidth and reduces energy consumption.
Additionally, it is advisable to avoid using 4G to play videos, as browsing via WiFi consumes less energy. Using a cellphone for quick searches instead of a computer can also help, as a computer has a bigger screen and uses more power. Reducing screen time in general can significantly reduce digital pollution.
It is also worth noting that the production and consumption of digital devices contribute significantly to digital pollution. Therefore, it is essential to extend the lifespan of devices, repair them when possible, and favour second-hand products over new ones to reduce the environmental impact of digital device consumption.

Delete unused apps and emails
The internet has become a lifeline for many, allowing us to send emails, share pictures, and download music and videos at the touch of a button. However, our online habits have a surprising impact on the environment. Digital technologies account for around 4% of global carbon emissions, a contribution similar to that of the aviation industry.
Data centres, which are storage centres of digital information, are responsible for much of this pollution. They require a lot of electricity to run and need to be kept cool to avoid overheating. Every time we use the internet, data gets transferred between our device and the server that the website or software is hosted on. Each server is kept switched on and working 24/7, consuming energy and requiring cooling systems.
One way to reduce your digital carbon footprint is to delete unused apps and emails. Deleting unused apps can help avoid unnecessary energy usage by the servers they are stored on. It is also beneficial to delete old emails and unsubscribe from unwanted newsletters. The transmission and storage of emails contribute to carbon emissions, and the carbon footprint of our inboxes can stack up over time. Spam emails are particularly polluting, so regularly emptying your spam folder can help reduce the amount of CO2 produced by systems keeping us online.
While individual messages, emails, and internet searches do not produce a large carbon footprint, they add up quickly when billions of people are online. By deleting unused apps and emails, you can help reduce the environmental impact of your online habits and contribute to a greener digital world.

Limit data centre usage
Data centres are high-tech buildings that house thousands of computer disks, or servers, that store and transfer our data. They require a lot of electricity to run and keep cool, and the more data that is sent and stored, the more electricity and energy is needed.
To limit data centre usage, there are several actions that can be taken:
- Delete unnecessary data: This includes emails, cloud storage, and apps that are no longer used. By deleting anything that is not needed, we can avoid data centres using energy to store this information unnecessarily.
- Minimise email usage: Emails create latent pollution as they are saved in three copies on at least three different servers. To minimise the impact, regularly classify and file your emails, avoid sending large attachment files, and unsubscribe from newsletters you no longer read.
- Reduce video streaming: Watching online videos generates a lot of carbon dioxide as it requires power for both devices and the servers and networks that distribute the content. Opt for downloads over streaming, and reduce the quality of videos to save bandwidth.
- Improve equipment usage: Upgrade equipment less often, and when using devices, switch off routers when possible, and deactivate GPS, Wi-Fi, and Bluetooth functions when not in use.
- Use data usage limits: On Windows 10 and 11, you can set data usage limits to reduce the amount of internet data you use. This is particularly useful on mobile connections with high data usage fees.
By taking these actions, we can help to reduce the energy demand and carbon emissions associated with data centres.

Upgrade equipment less often
Upgrading equipment less often is one of the ways to reduce the carbon footprint of digital technology. The greenhouse gases emitted during the manufacturing and transportation of electronic devices can account for a significant portion of the lifetime emissions of a device. For instance, a study at the University of Edinburgh found that using a computer and monitor for six years instead of four could save up to 190kg of carbon emissions.
The manufacturing phase of electronic devices is the most energy-intensive and carbon-emitting stage of a product's life cycle. This is due to the extraction of raw materials and the manufacturing process, which often takes place in developing countries that rely heavily on coal for electricity generation. The transportation phase further adds to the carbon footprint of electronic devices. Therefore, by extending the usage period of our equipment, we can significantly reduce the environmental impact associated with the manufacturing and transportation of new devices.
It is important to note that the smaller and more sophisticated the device, the larger its environmental impact is likely to be. This is because smaller devices require rare and conflict minerals, such as tantalum and tungsten, which are at the centre of armed conflicts, particularly in Africa. By upgrading our equipment less often, we can reduce the demand for these minerals and the environmental and social impacts associated with their extraction.
Additionally, it is worth mentioning that the energy consumption of our devices during their usage also contributes to their overall carbon footprint. However, this usage phase often accounts for less than a third of the energy consumed during a device's lifetime. Therefore, by using our equipment for longer, we can reduce the proportion of lifetime emissions associated with the manufacturing and transportation phases, making a more significant impact on reducing our digital carbon footprint.
To further reduce the environmental impact of our digital technology, we can also change how we use our devices. For example, we can reduce our carbon footprint by sending fewer emails with attachments, using more energy-efficient search engines, and reducing our consumption of online videos, which account for a significant portion of global internet traffic and carbon emissions.
