How Green is Your Website?

On average, a single website visit emits 1.76g of CO2 due to the intense processing power required to load and deliver a page. With over 1.13 billion websites competing for attention and web pages full of data, it’s no wonder that the internet guzzles up energy like a thirsty monster. And if you add a sluggish website to the equation, you not only frustrate visitors but also add to energy waste, exhaust your server, and increase electronic waste. To see how green is your website, click here.

How to reduce your website’s carbon footprint?

There are several ways, including using green hosting, optimizing website performance, reducing file sizes, and more. Here are some steps on how to create a more sustainable website.

Use green and reliable hosting

A more sustainable internet

When selecting a hosting provider for a web project, choosing one that uses renewable energy is an effective way to reduce your carbon footprint. It’s a simple and impactful step towards a more sustainable internet.

Data centres close to your users

Every website lives on a physical server somewhere in the world. The closer that server is to the majority of your website visitors, the faster your website will load for them, and the less energy it will consume.

Servers run on the latest tech stack

Server technology stacks are becoming more efficient in the pursuit of improved web performance, achieving the same outcomes with less processing and energy. Using the latest stable web technologies generally delivers optimal performance, security, and energy efficiency.

Blocking bad bot traffic

Websites consume energy every time they’re visited, and this includes bots. Preventing unwanted bots can enhance security, reduce energy usage, and have no adverse effect on users.

Optimize website resources

Improve media files use

Remember that media files take up a large chunk of your website’s data. Optimizations like lazy loading, image compression and adopting next-gen formats such as WebP will reduce the amount of data on your website without compromising its quality. This will result in faster loading time while saving energy.

Use simple fonts

Pixels are using energy to load. So, when choosing a font for a web-based project, it’s essential to consider the amount of energy required to load it. To reduce energy consumption, it’s recommended to use fewer fonts, preload the ones you’re using, and remove the ones you’re not.

Optimize front-end

Optimizing HTML, CSS and JavaScript files will significantly decrease loading time by cutting down on file sizes. Making your website faster and more energy efficient is a sure way to make it stand out.

Implement a caching strategy

Server-side caching

Caching is a powerful technique that allows your website to store and access data quickly. This means that when users visit your site, the server can grab the data almost instantly and voilà, lightning-fast loading time.


Web projects that have an international user base, using a content delivery network (CDN) helps to reduce the distance that large files travel through networks to reach each user, and thus reduces energy consumption.

What are Your Carbon Emissions?

There are many existing approaches to calculate website emissions, and the score may vary depending on the calculation method used. Calculate the environmental impact of your web page here. Your score will be based on the submitted web page weight, speed, energy used to load, and whether it is hosted on a green host.
