Blocking advertising on the web is not only good for increasing the speed and privacy of your own web browsing, but also good for the planet.
What is the environmental impact of visiting the homepage of a media site? What part do advertising, and analytics, play when it comes to the carbon footprint? We tried to answer these questions using GreenFrame, a solution we developed to measure the footprint of our own developments.
The results are insightful: up to 70% of the electricity consumption (and therefore carbon emissions) caused by visiting a French media site is triggered by advertisements and stats. Therefore, using an ad blocker even becomes an ecological gesture.
Overall we observe the same thing: the carbon footprint of a website decreases if there are no ads or trackers on the website. The difference is significant: Between 32% and 70% of the energy consumed by the browser and the network is due to monetization.
The websites analyzed generate between 70 and 130 million visits per month, and their work has therefore a real impact on the environment.
Reducing the consumption of one of these sites by only 10% (20mWh), per visit for a site with 100 million monthly visitors is equivalent to saving 24,000 kWh per year.
