Frequently asked questions

What is the link between web performance and carbon footprint?
A high-performing site is a lightweight site: less data transferred, fewer server requests, less processing time. Every kilobyte saved reduces the energy consumption of servers, networks, and user devices. Optimizing performance directly reduces the carbon footprint.
How do we measure a site's carbon footprint?
We evaluate the weight of the pages, the number of HTTP requests, server consumption, and the energy mix of the host. Tools like GreenIT Analysis and Website Carbon Calculator can estimate CO₂ emissions per visit and compare before/after optimization.
Does eco-design degrade the user experience?
On the contrary. Eco-design involves removing the unnecessary, not the essential. A sober site loads faster, works better on older devices, and offers smoother navigation. Users benefit just as much as the planet.
What is RGESN?
The General Reference for Eco-design of Digital Services is a French framework that defines best practices for eco-design. It covers the entire lifecycle of a digital service: design, development, hosting, and use. I support you in complying with this framework.

Responsible digital: why act now

Digital technology accounts for 3.7% of global CO₂ emissions, a figure that is constantly increasing. The average weight of web pages has doubled in five years, leading to higher energy consumption in data centers, networks, and user devices. Every loaded page consumes electricity at every link in the chain.

Reducing the carbon footprint of your site is not just an environmental gesture: it is also a competitive advantage. Consumers are increasingly sensitive to the ecological commitments of brands, and European regulations are pushing for more transparency regarding the environmental impact of digital services.

Performance and simplicity: two sides of the same coin

Optimizing web performance and reducing carbon footprint share the same levers. Compressing images, reducing JavaScript, caching resources, limiting server requests: each performance optimization is also an environmental optimization. A site that weighs 500 KB instead of 5 MB transfers ten times less data, which directly translates to reduced energy consumption.

This convergence is an opportunity: by working on performance, you simultaneously improve user experience, SEO, and your carbon footprint. There’s no need to sacrifice one for the other.

Measure to progress

You can only improve what you measure. A carbon audit of a website evaluates page weight, the number of requests, server consumption, cache efficiency, and the impact of third-party scripts. This data allows you to target high-impact optimizations and quantify the results achieved. Reference tools like GreenIT Analysis, Website Carbon Calculator, and EcoIndex provide comparable and recognized metrics.

Eco-design in service of the user

Digital eco-design does not mean creating austere and stripped-down sites. It encourages questioning every element: is this autoplay video necessary? Is this 20-slide carousel being viewed? Does this third-party marketing script really add value? By eliminating the superfluous, you achieve a faster, more accessible, easier-to-maintain site — and one that consumes less energy. Ultimately, eco-design is a design discipline that benefits everyone.
