This refers to the potential reductions in carbon emissions that could be achieved by optimising the efficiency of your webpage, such as by streamlining code, reducing file sizes, and using more energy-efficient hosting solutions.
Data Size
Improvement
This refers to the potential enhancements in reducing the overall data footprint of your webpage, which can be achieved through techniques such as compressing images, minifying CSS and JavaScript files, and leveraging browser caching.
