Sustainable web design is a fundamental aspect of Green Computing that aims to reduce carbon emissions and energy consumption. This paper explores sustainable website development by assessing best practices, comparing design approaches, such as minimalist design, code minimisation and clean code, efficient image compression, reduced reliance on heavy JavaScript frameworks and Content Delivery Network (CND) services, optimised caching strategies and examining methodologies contributing to energy efficiency.
This paper presents a practical framework for sustainable website design. It incorporates renewable energy hosting, lightweight coding principles and evidence-based sustainability interventions. The framework was implemented and tested on The London Library website, yielding a remarkable 99% reduction in carbon emissions per visit. The results prove how crucial it is to track environmental metrics and offer applicable steps for creating websites that are not only eco-friendly but also high-performing.
The London Library website was selected for this project due to its consistent, high-traffic usage, particularly among academic audiences. Although such sites may appear to have a limited environmental impact, our findings reveal that substantial reductions in carbon emissions are achievable without compromising performance or user experience. This transformation highlights the untapped potential of sustainable optimisation even for seemingly efficient websites.
