What is the environmental footprint of the 10 most visited m-commerce sites and apps in France in 2023?
The e-commerce market in France in 2022 amounted to 146.7 billion euros in sales. This is a growth of 13.8% compared to 2021. Although the turnover (CA) of product sales is down compared to the previous year, the considerable increase (+36%) in the CA of service sales supports the overall growth of the e-commerce sector.
There were 2.3 billion transactions made on the internet in France in 2022, 6.5% more than in 2021. Inflation and the sale of services contributed to an increase in the average basket with 6.9% increase. It was on average 65 euros in 2022.
This article can be used as a comparison with the previous content made on the subject in 2022. The article focused on the e-commerce figures in 2021 and the ranking of m-commerce apps and websites in the 2nd quarter of 2021.
E-commerce refers to all transactions made on the Internet, while m-commerce refers to all types of purchases made on an e-commerce website with a mobile device. M-commerce is therefore a sub-category of e-commerce.
Selection method of websites and applications
For this new version, we based ourselves on the measurement of the 10 most visited m-commerce sites and applications in France (figures of the 4th quarter 2022 exposed by Fevad). Compared to the previous ranking, 2 players have appeared: Rakuten and Darty. It is eBay and ManoMano that are out of the top 10.
User path definition
After refining the selection of the 10 applications and websites to be measured, we went back to the path that was defined in last year’s article.
Implementation of Greenspector’s solution
We used our innovative solution to measure the environmental impact of different stages of the user journey. We ran the automated tests several times on a real device, in this case the Samsung Galaxy Note 8. We measured resource consumption (energy, memory, data) and response times. This data then allowed us to obtain the environmental impact of applications and websites. We explain it all in detail in our methodology.
Ranking of the environmental footprint of the 10 most visited m-commerce sites in France
The 3 sites with the least impact are : Leclerc, Leroy Merlin and Fnac.
Compared to the article published last year, Cdiscount is back on the podium while the Fnac site is in the top 3 of the least impactful sites.
The 3 most impactful sites are: Amazon, Rakuten and Darty.
The Amazon site is 2.2 times more impactful than the Leclerc site.
The average carbon impact of these 10 websites is 1.09gEqCO2 for an average duration of the scenario (see methodology at the end of the article) of 1 minute and 58 seconds, which is the equivalent of 5 meters driven by light vehicle.
Projection of global carbon impacts over one month
In last year’s article we based ourselves on the figures presented in the ECN report. For this new study, we used the Fevad barometer enriched by Médiamétrie in order to be as close as possible to reality.
For this projection, we consider that the share of global e-commerce traffic is 55% on mobile, 39% on PC and 6% on tablet (source). We also used the ADEME tool to project the equivalences.
With an average of 16.15 million monthly users and an average visit time of 5 minutes and 50 seconds, these 10 e-commerce sites have an average projected impact of 172 tons of CO2e per month (29 tons on mobiles, 139 tons on PCs, 4 tons on tablets). This is the equivalent of 20 times the circumference of the Earth covered by a light vehicle.
Impact projection for the most and least sober website
Concerning the best website of this ranking (Leclerc) for 14.84 million visits / month with a duration of 3 minutes, the total carbon impact would be 58 tons of EqCO2 per month (9 tons on mobile, 47 tons on PC and 1 ton on tablet). This is the equivalent of 6 times the circumference of the Earth travelled in a light vehicle.
Concerning the worst website of this ranking (Amazon) for 38.29 million visits / month with a duration of 8 minutes, the carbon impact would be 690 tons of EqCO2 per month (121 tons on mobile, 553 tons on PC and 15 tons on tablet). This is equivalent to 79 times the circumference of the Earth travelled by light vehicle.
Ranking of the environmental footprint of the 10 most visited m-commerce applications in France
The 3 applications with the least impact are: Carrefour, Darty and Veepee
The 3 most impactful applications are: Amazon, Aliexpress and Leroy Merlin
We observe that the Amazon application has a carbon impact 3 times higher than the Carrefour application.
The average carbon impact of these 10 applications is 0.81 gEqCO2 for an average scenario duration of 1 minute and 58 seconds, or the equivalent of 3 meters driven in a light vehicle.
Review of the study
This year again we observe that the impact is almost three times greater between the most sober platform and the one with the highest impact.
To shop online, it is better to use applications than websites. Indeed, in the scenario studied, websites have on average 44% more impact. Only Leroy Merlin and Leclerc have a greater carbon impact on applications than on the web. We remind you that applications have an impact on their download and their updates. They are therefore to be preferred only in case of regular orders.
We would like to complete this assessment with an observation we made during our tests. Indeed, we observed that on some websites and applications the path could change or be altered. This is the case for Amazon which has implemented AB testing. This method allows the application and the website to vary the displays. For example, on the description of a product, the description can be different from one user to another.
In our case we encountered a phenomenon of change of path on the Amazon website. During a first test we were redirected directly to the shopping cart with the addition of the product to it. In a second test the next day we were no longer automatically redirected to the shopping cart page. Instead, we had to go to the shopping cart ourselves by clicking on the icon provided for this purpose.
Depending on the path, the site or application will consume more or less energy and exchange more or less data. AB testing is a feature used by many digital solutions in the world and we handle it in our path automation thanks to our GDSL language. In the case of our study we have of course taken care to base our measurements on a single path.
