In France, web eco-design is shifting from a voluntary best practice to a structured standard. The law on reducing the digital sector's environmental footprint (known as the REEN law) set the framework back in 2021, and the General Reference Framework for Digital Service Eco-design (RGESN), published by Arcep and Arcom with support from Ademe, now breaks it down into 78 concrete criteria for designing a site or application. Page weight, especially images, which often account for the majority of bytes transferred on a product page, sits at the center of it, alongside the number of HTTP requests or DOM complexity.
The push behind this movement is backed by numbers: digital technology is estimated to account for around 4.4% of France's greenhouse gas emissions, a share several reports (including those behind the RGESN) project will keep growing without added sobriety in service design. Concretely, several RGESN criteria target media directly: capping the total weight of images loaded per page, avoiding serving a resolution larger than what's actually displayed, favoring modern compressed formats, and loading only what's actually visible on screen rather than an entire gallery or carousel.
For a private online store, it's worth not overstating the RGESN's reach today: it remains, for the most part, soft law, a set of best-practice guidelines, not a legal obligation applying to every merchant site. Only part of the public sector and organizations bound by the REEN law must formally comply. But the trend is clear: public procurement increasingly requires it from vendors, some large private clients are starting to write it into their specifications, and the same criteria largely overlap with what Google already uses for ranking (Core Web Vitals), so optimizing for eco-design also mechanically improves a store's perceived speed and SEO.
That's exactly the angle ImagePipe covers without any extra configuration needed to target these criteria: the engine only ever generates a single variant per actual size/format combination a browser requests, cached once rather than duplicated into dozens of unused sizes at upload time. Modern formats (WebP, AVIF) are served automatically as soon as a browser supports them, cutting transferred weight with no manual step on the store's side. For a store that might one day need to answer a tender requiring RGESN compliance, or simply wants to shrink its footprint out of conviction, image handling usually isn't the most expensive item left to bring into compliance, it's often already done, without anyone having had to think about it.
