There are several features that can be incorporated into a website design to make it more sustainable, including:

1. Minimalist design: A minimalist design that uses fewer graphics and visual elements can help reduce the website’s carbon footprint by reducing the size of the website’s files and the number of requests made to the server.
2. Efficient coding: Efficient coding can help reduce the amount of energy required to load the website. For example, compressing images and using efficient coding techniques such as minification can help reduce the website’s carbon footprint.
3. Green hosting: Choosing a web host that uses renewable energy or carbon offsets can help reduce the carbon footprint of the website.
4. Responsiveness: A responsive design that adapts to different devices can reduce the number of requests made to the server and the amount of data transferred, which can help reduce the website’s carbon footprint.
5. Sustainable content: Using sustainable content, such as images and videos that promote sustainability, can help align the website’s content with its sustainability message.

Incorporating these features into a website design can help reduce the website’s environmental impact and make it more sustainable.
