6 easy ways to reduce your website impact


900+ millions tons of CO2 is Internet’s carbon footprint today and this number will double by 2030. Businessmen and developers need to adopt greener practices.

Websites can be made more sustainable by reducing the amount of computation and network involved in serving, delivering and rendering the website on the users devices. 

A few of the many techniques that can be used to reduce your website impact include: 

  • Optimizing image sizes and using more efficient image formats such as vector images instead of bitmaps. For example SVG images are more eco-friendly than PNG.

  • Reducing or eliminating the use of video, especially autoplay video, or replacing video with animations, which are typically more power-efficient. For example the video advertisements have a high environmental impact, especially when they are loaded using 4G network instead of wifi.

  • Reducing trackers and advertisement can reduce the carbon footprint of a website up to 70%

  • Simplifying page design, font choices and so forth to reduce transmitted data and the number of pages served

  • Exploiting network caching effectively to reduce traffic 

  • Developing the website using more eco-friendly code-languages. Some studies have shown that some programming languages use 70 times more energy for the same task than others. https://haslab.github.io/SAFER/scp21.pdf
