Eco friendly websites

Creating a greener, faster, more sustainable digital world

If you are searching for eco friendly websites or sustainable web design, you are probably looking for ways to reduce the environmental impact of your digital footprint. The truth is, the internet has a surprisingly large carbon footprint. Every time a page loads, it uses electricity from servers, networks, and devices all around the world. You can learn more about your own site’s performance in our post on calculating your website’s carbon footprint.

The great news is that you can make your website significantly greener with a few simple, thoughtful changes. These improvements not only reduce energy use, they also make your site faster, easier to use, and often cheaper to run.

In this article, you will find out what makes a website environmentally responsible and how you can start making improvements.

Eco friendly web design matters

There is a growing awareness of the carbon footprint of digital technology. Data centres already account for more CO₂ than the aviation industry, and the numbers are rising. Every time someone loads your homepage, energy is used across servers, networks, and devices. If your website is heavy and bloated, that energy use increases.

Beyond the environmental benefits, a sustainable website almost always delivers a better experience. Faster sites perform better in search results, keep visitors engaged for longer, and feel smoother on both desktop and mobile. Visitors expect fast loading websites, and Google rewards them. If you care about SEO, speed and efficiency are essential.

An eco-friendly website also sends a positive signal about your brand. People increasingly want to work with companies that care about their impact, and your website is one of the easiest and most visible places to show that commitment.

Making your website more eco friendly

A great place to start is your hosting provider. Many businesses now use green hosting, where the servers are powered by renewable energy. This instantly lowers your website’s carbon footprint without changing anything on the front end. If someone is specifically searching for eco friendly web hosting, this is usually what they mean.

Another big win is image optimisation. Oversized images are one of the most common causes of slow, energy hungry sites. Converting images to modern formats like WebP, compressing their file size, and loading them only when needed can dramatically cut your page weight. It is one of the simplest changes you can make, and it has a huge effect on both performance and sustainability.

Your website’s code also plays an important role. Clean, lightweight code loads faster and uses fewer resources. That might mean removing old plugins, reducing unnecessary JavaScript, or choosing simpler frameworks. Modern CSS techniques often replace what used to require complex scripts, making things quicker and greener.

Design is another area where sustainability and user friendliness overlap. Websites with clean, simple layouts are not only easier to navigate, they also require fewer files and less processing power. Minimalism is not just an aesthetic choice, it genuinely reduces your website’s carbon footprint. Clear content, fewer distractions, and thoughtful spacing contribute to a smoother, more energy efficient experience.

Finally, it helps to build websites that last. A well planned, flexible website can grow with your business rather than being rebuilt every couple of years. This reduces digital waste, saves money, and keeps your website’s carbon footprint lower over its lifetime.

Examples of low impact websites using Umbraco

Etive Mòr rebuilt their site using Umbraco (plus some modern frontend tech) to cut CO₂ emissions significantly. Their home page went from ~800 KB down to about 189 KB, and their site now produces as little as 0.03–0.06 g CO₂ per page view (versus ~0.24–0.25 g previously). They also reduced server energy consumption and dev-ops overhead dramatically, while hosting costs became minimal. 

Innovation Centre for Organic Farming was built around sustainability from the start. It avoids unnecessary cookies (privacy friendly), is fully accessible, and uses green hosting (renewable energy). Image/video content is compressed and sensibly loaded, and the site is optimised for low energy use. As a result it ranks among the top 10% most climate friendly sites globally!

When Agria moved their web estate to a modern Umbraco build, they achieved a 59% reduction in carbon footprint, along with a 29% increase in sales (improving performance while going greener). This shows how sustainability and business benefits can go hand in hand. 

You can also check out various lightweight, low carbon websites on the lowwwcarbon directory. This directory showcases many small websites designed with carbon and data efficiency in mind. They boast minimal images, streamlined loading, and reduced resource use. Some of the sites are very simple but elegant and “green by design,” offering good inspiration for lean, efficient site builds. (You might even spot a few of our websites listed on there!)

Your choices make a difference

Creating an eco-friendly website is not about aiming for perfection, it is about taking smart, thoughtful steps that make a real difference. Every improvement, whether it is lighter code, greener hosting, or simply being more intentional, helps create a faster, cleaner, more enjoyable experience for the people who visit your site.

As you have found yourself searching for eco friendly websites, it means you already care about building something responsible, modern, and efficient. That mindset is exactly what sustainable web design is all about.

Most importantly, thank you for taking the time to learn how your website impacts the world around it. By educating yourself and taking action, no matter how small, you are contributing to a healthier digital ecosystem and a more sustainable future. And that step matters.
