Sustainable web design is an approach to designing digital products and services that are conscious of lowering carbon emissions by becoming more efficient. The internet may be digital, but it runs on electricity, much of which is still produced by fossil fuel. The choices we make in designing digital Products, from UX and development to the servers we use can have a carbon cost and can contribute to global Greenhouse gases. To help with this topic, in August last year, W3C released first draft of Sustainable Web Guidelines and they have been evolving and helping community ever since. As a part of W3C Sustainable Web Community Group, I got to work on these guidelines and would love give a sneak peak into its development process and show how to best leverage them to design digital products that put people and planet first.
