Before the redesign, the scoreddb.fr website, a few years old, displayed these scores:

• 1.60g of CO₂ produced per visit (according to websitecarbon.com). The site was more polluting than 86% of pages tested – to understand this score, see our article “Measuring a Website’s Footprint with websitecarbon.com.”

• EcoIndex score: F (average across the site’s pages). Pages were too heavy, too complex, with too many requests (237).

• Google PageSpeed Insights score: 18% on mobile – very slow and heavy.

• The site already benefited from eco-friendly hosting.

These scores are typical for an older website with lots of content, images, and videos. The redesign was therefore a great opportunity to improve all of this.

A genuine commitment from SCORE DDB to push the boundaries of digital eco-design

“As a communications agency, it was unthinkable for us to do without colors, visuals, or videos for this new site, or to use gimmicks like a ‘low-consumption mode’ switch. The experience on the site had to remain as effective as possible while achieving the best environmental performance scores and reducing its carbon footprint.” — Gautier Linard, who led the project at SCORE DDB

From the start, we had a major constraint: an auto-play background video on the homepage — the nemesis of eco-design.

But our client’s high expectations challenged us to go further. And since we love to push ourselves — plus the client was genuinely nice, and the site looked great — we went through every nook and cranny to optimize our pages:

• Pixel-perfect adjustment of all image sizes (loaded vs. displayed).

• Optimization of the homepage video’s operation.

• Optimization of scripts and styles with a custom plugin developed by our CTO, Alex Hoyau, specifically for this project: “Concat” — now available as open source (you’re welcome!).

The results of the SCORE DDB redesign: an eco-designed AND beautiful website

• 0.04g of CO₂ produced per visit (websitecarbon.com) for the heaviest page — less polluting than 92% of pages tested, and a 95% reduction in CO₂ emissions.

• EcoIndex score: A (average across the site’s pages). Light, simple pages with few requests. EcoIndex also shows a 46.5% reduction in CO₂ emissions compared to the original site.

• Google PageSpeed Insights score: 96% on mobile — a gain of 78 points.

The average page weight is 500 KB — half the current average weight of a webpage on the internet (source).

The benefit of all these scores? Lower environmental impact and better user comfort — even on mobile, even with a poor connection.
