Digital photo albums and music collections are nothing new; for years now, internet users have been able to manage their music and images online. This phenomenon allows us to share our snaps with friends via social media platforms and listen to our favourite songs while on the go. The paperless office is the workplace equivalent, and although the number of companies turning digital seems to be...

What does website design have to do with the environment?
Internet use is now responsible for the same level of CO2 emissions as global air traffic and accounts for around ten percent of global electricity consumption. Diesel vehicles, aeroplanes, and cruises easily spring to mind when it comes to environmental pollution, but we ought to consider smartphone and computer use in addition when it comes to our carbon footprint.
The main reason for the Internet’s high energy requirements are the servers in data centres around the world, whose power consumption and cooling generate two to four percent of global CO2 emissions each year. But ultimately, websites also play a role: the more data a website consumes, the higher its power consumption. A simple website, for example, generates around 1.76 grams of CO2 per view. 20,000 views are already 352 kilograms of CO2.
It is therefore more than appropriate that IT companies and developers promote environmental protection and sustainability. This can be achieved through sustainable web design (also known as green web design).
What are the advantages of a sustainable website?
Whether it’s a professional website for artists or businesses, a personal blog, or a private website as a hobby, sustainable web design offers many advantages from an environmental perspective as well as for performance and reputation reasons.
- SEO optimisation via better ranking: A fast page loading speed and a user-friendly design can also have a positive influence on search engine rankings. Indeed, both are among the most important Google ranking factors. For this reason, sustainable web design is also important for search engine optimisation (SEO).
- Positive branding: For companies it is important to think about sustainability strategies in addition to implementing them for customers in the form of Green Marketing. This includes green web design, which can be displayed on your website and thus ensures a better, environmentally conscious brand and corporate perception.
- Environmental protection and resource conservation: Efficient websites with long-lasting, sustainable design not only have a positive impact on visitor numbers and business success, but also on the environment. Less power consumption through sustainable websites and green hosting with green power mean less CO2 emissions and thus a contribution to more sustainability.
Web hosting from IONOS is fast, secure and flexibly scalable, and also in line with green web design: we run our data centers using electricity from renewable sources.
Here’s how to set up sustainable web design
The word `sustainability´ is a buzzword in all areas of society – and we often see signs of sustainability in business in the form of certificates and seals of approval. While most people can visualise what sustainable agriculture, waste reduction, and emission-free traffic look like, sustainable web design remains a bit of a head-scratcher. The question with green web design is: What does a sustainable website even look like? Below, we’ll present four points that will help you understand and use sustainable web design.
Data-saving web design
For more sustainability through energy- and data-saving web development, it comes down to three points:
- Avoid unnecessary data consumption
- Provide an efficient page architecture
- Use only media data with added value
Images, thumbnails, videos, style elements, advertising banners and animated page areas in particular use a lot of data, increase energy consumption and consequently increase emissions. Instead of overloading pages, use appropriate tools, compress images, and offer high-resolution video quality as an option rather than default. In addition, check which multimedia elements offer any added value to your site visitors at all.
Further energy-saving green web design tips and tricks include:
Sustainability also means durability. A website that has a timeless and universally design — and does not follow short-lived fashion and design trends — ages more slowly and reduces the effort required for redesign and revision. This not only saves on staffing costs, but also electricity costs for time-consuming relaunches. Minimalist elegance with a clear, pragmatic structure and a long-term classic aesthetic is a sensible step towards green web design.
Green hosting and Green IT
According to the Guardian, the internet produces 300 million tons of CO2 per year, a quarter of which is emitted by data centres. That’s a staggering number, so if you want to offer a sustainable website, you should also think about the power consumption of the servers in web hosting. Green Hosting is the term used for hosting servers and data centres that are powered by electricity from renewable sources. So, as a website owner, pay attention to whether Green Hosting is offered or used by your host.
Green IT in turn, focuses not only on energy supply, but also on sustainable and holistic production and provision, smart IT use, and proper disposal of IT products.
You can recognise providers with green IT and green hosting strategies as follows:
- Use of green electricity for server operation
- Proper disposal or recycling of old hardware
- Use of hardware with eco-certificates/labels
- Certified energy management
- Certified reduction of CO2 emissions
- Promotion of environmental protection projects
- Intelligent infrastructures (e.g. through virtualized and centralized services)
Make your online presence green with sustainability from IONOS. We run our data centers and offices on green power, use efficient IT infrastructures, and offer intelligent energy management for environmentally friendly processes.
Clear, sustainable code
Tools to check the sustainability and functionality of code include refactoring tools that check changes and replace obsolete code elements with new ones. There are also verification tools that check codes for their intended behavior, spot errors, and facilitate integrations. By keeping your code as clear and concise as possible, you’ll prevent code smell and code rot (obsolete, useless code elements) in the long run, not only increasing code efficiency but also improving your website’s carbon footprint.
