How Sustainable Is Your Website?

13th June, 2019 by

Did you know that the internet accounts for 2% of all greenhouse gases?

The level of emissions released by the web equates that of the entire country of Germany or the entire aviation industry.

With 3.5 billion website users and a single website view equating to 20 milligrams of carbon per second, you can imagine how the emissions can quickly reach concerning levels.

While this may sound grim, there are ways to be sure that your website and internet usage are as sustainable as possible.

So, what do we do about it?

Is your website green?

A lot of your website’s sustainability depends on the size of your website. If you run a very large, or enterprise-level, website, then it might not be very green. However, if you run a small website with very few pages, you can assume that your carbon footprint is pretty small.

The average website is 1711.4kb, but a large majority of this size may be due to the inclusion of video on websites. Custom fonts, images, and javascript also add bulk to the average website size. You can check the size of your website at Small SEO Tools. Remember that if your website seems to be measuring larger than it should, there are several steps you can take to reduce its size, and in turn reduce your website’s carbon footprint.

Additionally, to check exactly how much your website is contributing to total greenhouse gases, head to and enter your URL. Once your website is evaluated, you will have access to information like how many grams of carbon is created with every website view, as well as the yearly amount of carbon created by having your website online.

Ways to keep your website green:

If, after some research, you have decided that your website could be greener, there are a few steps you can take to be sure that you are doing your part to keep the world as green as possible.

*Note: Remember that a faster-loading site also boosts your website search engine optimization, so helping the planet is also helping yourself!

#1. Reduce image sizes.

Be sure that your images are optimized, and only include as much detail as required for quality purposes. High-resolution images are very heavy, but by reducing the size of your images you can drastically decrease the overall size of your website and ultimately help the environment.

#2. Be careful with video.

A lot of great websites include video, however, they are not as green as we would like them to be. Consider your videos carefully, be sure that they are not set to autoplay, and avoid using videos as a background when possible to keep your website slim.

#3. Keep it clean.

Check your website files and directories often for content that you no longer need. If you operate a WordPress website, delete plugins that you are no longer using as well as blog posts and images that have been unpublished. By deleting older plugins and widgets you can also greatly improve your website security.

#4. Use web caching.

Web caching allows users to save a copy of your website on their machine so that it loads much faster the next time they visit your website.

#5. Choose a great web host.
