In today's digital age, there is increasing attention being paid to the ecological impact of technology. Although we perceive the internet as "intangible", its operation has real physical consequences for our planet. Digital media sustainability therefore, it represents a complex challenge today, encompassing everything from the frugal architecture of websites to the daily habits of editors in the offices. The goal of a modern news website should not only be high readership, but also minimizing its carbon footprint and protecting the health of employees from digital burnout.

The environmental impact of the digital world

Every single web page load consumes energy in data centers, transmission networks, and user end devices, which inevitably produces CO₂ emissions. While a single click may seem insignificant, on a mass scale these are huge numbers. The average website generates approximately 0.3 to 0.36 g of CO₂ per load. If your website has 10,000 views per month, it will produce around 40 to 50 kg of CO₂ per year. Multimedia-heavy sites can increase this footprint to several grams per view.

The global view is even more alarming. Data centers and networks today produce approximately 1.% of total greenhouse gas emissions, representing hundreds of millions of tons of CO₂. In 2022, data centers consumed 460 TWh of energy and this consumption is expected to increase to 1050 TWh by 2026. If we are to achieve climate goals, it is essential that the internet’s data footprint is halved by 2030.

Technical Optimization: The Path to a „Lightweight“ Website

The most effective way to reduce your web's emissions is to switch to „"green hosting"“, i.e. the use of data centers powered by renewable energy sources such as wind or sun. Editors can verify the provider, for example, through the Green Web Foundation.

Besides hosting, the website architecture itself is key. A simple rule applies: the lighter and faster the design, the lower the emissions.This includes:

• Image optimization: Using modern formats such as WebP or AVIF and "lazy-loading" techniques, where content is only loaded when the user scrolls to it.
• Code cleaning: Removing unused CSS and JavaScript (called tree-shaking) significantly reduces unnecessary consumption. To illustrate, images account for about 0.2g of CO₂ per display, while JavaScript adds another 0.08g.
• Minimizing external elements: Every imported library, font, or ad increases data transfer. The ideal is a simple static page built on HTML and CSS without excess ballast.

Sustainable SEO and the fight against digital waste

Effective SEO management is not just about search rankings, but also about reducing „digital waste.“ Instead of quantity, editorial teams should focus on quality and credibility (EEAT concept). Implementing structured data, such as FAQ schema, allows readers to get answers directly in search results without having to load the entire page, saving energy.

Unwanted bots and scrapers are also huge energy guzzlers. Analysis of server logs often reveals that a large portion of traffic is made up of bots, which do not add any value. By blocking them in the robots.txt file, the editor can immediately reduce the server's ecological footprint.

Another area is data hygiene. According to available data, up to 90 % of collected data (analytics, logs) no longer needed after three months. Editorial offices should have a clear policy of deleting old records, which will reduce the energy load on storage and at the same time improve privacy protection. In connection with modern trends, one should also be cautious with AI search, which can consume up to 30 times more energy than classic search.

Green editorial office: Office and material flows

Sustainability doesn't end in the web code, but continues in the physical space of the editorial office. Just changing the hardware brings significant savings. Desktop PCs consume 65–250 W, while laptops only 20–50 W. Replacing old computers with energy-efficient laptops is therefore a quick step towards both lower electricity bills and lower emissions.

Editorial teams should also pay attention to:

1. Material flows: Global paper production is set to reach 400 million tons by 2023. Switching to a fully digital editorial office without printed drafts saves forests and costs.
2. E-waste: 62 million tons of electronic waste were produced in 2022. Old hardware should be recycled or donated.
3. Energy policy: Investments in LED lighting, smart thermostats, and automatic off-hours device switches are the foundation of an energy-efficient office.

Caring for editors and combating digital fatigue

Digital sustainability also has a human dimension. Working with technology brings risk digital fatigue and burnout. Chronic overload from multitasking and constant video calls leads to stress, sleep problems, and physical pain.

It is recommended to implement rules for „digital well-being“ (e-wellness), such as:

• Turning off cameras during online meetings, which saves not only energy but also mental capacity.
• Hybrid work mode, which combines the creativity of the editorial team with the savings in transportation emissions from working from home.
• Digital detox, i.e. clearly defined times (weekends, evenings) when employees do not contact each other. Quality technical infrastructure, including stable Wi-Fi, can increase productivity by up to 59 %, thereby reducing the time needed to work in front of a screen.

Content Lifecycle: Recycling and Archiving

Editorial teams generate a huge amount of content, the long-term storage of which on servers requires energy. Minimalism is a key principle in archives – only what has lasting value should be preserved.

Instead of constantly creating new content on the same topics, it is more sustainable update and recycle older posts in the form of infographics, podcasts or videos. The choice of formats is also important. Texts in universal Markdown or HTML are much "lighter" than bulky PDF documents. Editorial teams should regularly review their retention periods and not leave analytical records or old versions of websites on servers for many years without justification.

Comprehensive sustainability of an editorial website is not a one-time task, but a continuous process connecting technical solutions with organizational culture. From streamlining code and switching to green hosting, to blocking unnecessary bots, to supporting the ergonomics and mental health of editors – every step contributes to reducing the overall carbon footprint. Media have a unique opportunity to lead by example and show that the digital world can grow hand in hand with environmental responsibility. JRi&CO2AI
