Digital sustainability does not begin only on the server. It appears in every design, development, publishing and maintenance decision: how many resources are loaded, how much images weigh, which scripts run and how much energy each visit demands.
What digital carbon footprint means
A website’s digital carbon footprint is a way to estimate the impact associated with its use: data transfer, energy consumption from devices, networks, data centres and the frequency with which its pages are loaded.
Why it matters in cultural projects
Many cultural projects work with high-quality images, catalogues, archives, videos, publications and downloadable resources. All of this can add value, but it can also increase the technical weight of the website if it is not managed with judgement.
An institution that speaks about responsibility, memory, heritage or community should also care about the way its digital presence consumes resources.
What should be measured
It is useful to review total page weight, number of requests, image compression, use of modern formats, lazy loading, third-party scripts, caching and hosting efficiency.
Digital ESG and user experience
Reducing weight does not only improve sustainability. It also improves speed, accessibility, mobile navigation and the experience of people with slower connections or less powerful devices.
Optimisation priorities
In a first phase, it is worth optimising images, removing unnecessary scripts, reviewing fonts, reducing blocking resources, applying caching and organising content so that each page loads only what it truly needs.
The goal is not to impoverish the visual experience, but to make it smarter: the same aesthetic intention, less technical friction and greater responsibility.
