ChangeNOW 2022: Digital Sobriety Ranking of Partner Websites

Reading Time: < 1 minute

On the occasion of the ChangeNOW 2022 event, taking place from May 19 to 21 at the Grand Palais Éphémère in Paris, Greenspector measured the environmental footprint of the websites of the partners of the event.

Ranking of the environmental footprint of partners

The average carbon impact over one minute of navigation by these 98 partners is 0.50 gEqCO2, or the equivalent of 4.5 meters travelled in a light vehicle. Only 31 websites are above this average, which indicates a good trend. The soberest website in this ranking (the ADEME site, 0.2 gEqCO2) has 8.1 times less impact than the least sober site (heforshe, 1.62 gEqCO2).

The average power consumption (mAh) is 5.23 mAh, and an average of 8.36 MB of exchanged data. The average of web requests is 78.

EcoAct and Greenspector support France Télévisions in the decarbonization of its new media NOWU

Reading Time: 4 minutes

Press release

Paris, January 25 2022 — EcoAct, an Atos company, and Greenspector, a member of Scaler, the Atos Accelerator, that supports startups in their international development and fosters customer innovation, have been chosen by France Télévisions to assess and optimize the carbon impact of the website of its new media NOWU.

This digital editorial offering aimed at 15–25-year-olds was designed with energy efficiency in mind, with a low-carbon strategy and the integration of eco-design principles.

By combining their expertise, the two partners supported the eco-design and production of this public digital media, thanks to EcoAct’s 15-year strong experience and consultancy expertise in decarbonization strategy, and to the expertise and measurement solution from Greenspector, specialist in reducing the environmental impact of digital applications.

Carbon impact considered from the beginning of the project

To ensure the optimization and reduction of its carbon impact, EcoAct and Greenspector established a benchmark of best practices in low-carbon media and then calculated the carbon footprint of the project. At the launch of the project, the media’s carbon footprint was estimated at 74 tons of CO2 equivalent (this is, for example, 37 round trips from Paris to New York) and will be monitored over time as the service develops. Greenspector also studied the level of eco-responsibility of the media site, thanks to Greenspector’s digital sobriety certificate. NOWU was the first media to achieve a good result: an eco-score of 61/100, which corresponds to the bronze level.

Long term support

Thanks to these initial in-depth analyses, EcoAct and Greenspector were able to identify reduction levers for both the creation of the platform and its use, in addition to awareness-raising and training activities, combined in a concrete action plan with an ambition which was consistent with the objectives of the Paris Agreement.

“Eco-design was integrated from the very conception of the NOWU website. Right from the start, the digital team implemented best practices, including energy and resource consumption simulations which were developed according to use cases as close as possible to user behavior to detect potential overconsumption on the website. Our partnership with EcoAct has allowed us to better project the carbon impact of the project to make NOWU a benchmark in green media by design.” Thierry Leboucq, President of Greenspector.

“EcoAct is delighted to have been able to contribute to the implementation of a decarbonization strategy for a media that aims to raise awareness of sustainable development issues among young people. And Greenspector, thanks to its expertise in digital, has been a real support in the development and deployment of this strategy.” Yann Josse, Senior Business Manager, Public Sector at EcoAct.

“France Télévisions is proud to respond to the need for strong commitment from the younger generation with its innovative NOWU medium, which proposes concrete solutions to act in favor of the Planet. Together with EcoAct and Greenspector, we have taken up the challenge of offering young Europeans the authentic experience of a more sober and eco-designed digital platform, which combines raising awareness of the issues they care about with reducing resources consumption and their own carbon impact.” Gautier CURTIL, Director of Offerings – NOWU, France Télévisions.

Greenspector selected for LVMH’s La Maison des Startups program at Station F

Reading Time: 2 minutes

Greenspector has been chosen to participate in the 7th season of LVMH’s La Maison des Startups program at Station F.

Since 2018, LVMH’s accelerator program La Maison des Startups is located in Station F – Paris. Station F is the world’s largest startup incubator and welcomes 50 international startups each year. The co-design program aims to accelerate collaboration between LVMH Group companies and innovative startups.

The mission of the LVMH Accelerator Program is to “start conversations between our talents and our entrepreneurs, so these could blossom into wonderful collaborations..

“We are proud to have been selected for this 7th season of LVMH’s La Maisons des Startups program. Greenspector has already had the opportunity to work with the LVMH Group and the Maison Dior on impact measurement and evaluation. The goal of the House of Startups is to accelerate collaboration between its Houses and startups related to the luxury sector. Digital activities are becoming increasingly important for events and business aspects, for the Group’s various Houses and in general in the luxury and fashion sectors. Its impact tends to grow with its audience. Therefore, to see organic growth in digital uses, digital services must take their “share” of responsibility and reduce their environmental impact“, says Thierry LEBOUCQ, Chairman of Greenspector.

The 7th promotion includes five other startups in the Sustainability category, demonstrating a growing commitment to societal and environmental issues. This is the largest contingent since the program was created.

Greenspector wins the “Digital Sobriety Award” at the Mobility for Business 20

Reading Time: 2 minutes

Greenspector took part for the fourth consecutive year at Mobility for Business 2021. On the occasion of this exhibition dedicated to mobile solutions and applications, Greenspector won the “Digital Sobriety Award” of the Mobility Awards.

The Mobility Awards aim to distinguish the best achievements, the best products and the most innovative approaches to professional mobility. This award recognises our achievement: the Digital Sobriety Certificate.

The Greenspector team is proud to receive this award, which recognises the excellence of our solutions for a more responsible digital world, which have been adopted by our customers for several years now. The context of business mobility is particularly close to our hearts. Adopting a digital sobriety approach in this context means meeting CSR challenges. But it also contributes to performance (faster business applications, satisfaction of agents in the field), and it enables savings (more durable terminals have a lower TCO). Everyone wins: the environment, the users, and the IT department’s budget,” says Thomas Corvaisier, CEO of Greenspector.

What is the Greenspector’s Digital Sobriety Certificate?

Greenspector’s Digital Sobriety Certificate rewards the eco-responsibility of companies on consumer or business applications that have proven their good level of sobriety.

In particular, it ensures that the application’s resource consumption on the terminal is compatible with the business challenges: battery life, application speed, CO2 footprint. The certificate thus makes it possible to reward progress and encourage internal and external teams to produce more energy-efficient applications.

Greenspector’s Digital Sobriety Certificate already adopted by our customers:

What is the environmental footprint for social media applications? 2021 Edition

Reading Time: 4 minutes

The use of social networking-type mobile applications is increasing every year. Like the professional use of videoconferencing tools, these uses have put additional pressure on the network and the servers of these solutions.

How do the players take the environmental impact into account in their strategy? What are the impacts of our activities on social networks? What are the most/least impacting solutions for the environment, network congestion and the autonomy of our smartphones?

For this study, we chose to measure the news feed of the 10 most popular social media applications: Facebook, Instagram, LinkedIn, Pinterest, Reddit, Snapchat, TikTok, Twitch, Twitter, and Youtube. These applications are different in terms of functionality. We have chosen to compare them in terms of carbon impact, consumption of energy and data exchanged.

For each of its applications, measured on an S7 smartphone (Android 8), the scenario for scrolling the news feed was carried out through our Greenspector Test Runner, allowing manual tests to be carried out over 1 minute in one-to-one. Learn more about the methodology and How does Greenspector assess the environmental footprint of digital service use.

According to the Global Web Index July 2021, we spend an average of 2 hours and 24 minutes on social networks, i.e. +2 minutes compared to 2019. If we project the average carbon impact of the 10 applications measured (1.15 gEqCO2) out of 60 seconds to the average time spent per user, we obtain for one user/day: 165.6 gEqCO2. It is the equivalent of 1.4 km in a light vehicle. It also corresponds to 60 kgEqCO2 per user per year, or the equivalent of 535 km travelled in an average light vehicle in France. It is equivalent to 1% of the carbon impact of a French (7 Tons).

In May 2021, the number of active users of social networks stood at 4.33 billion (55.1% of the world population), or + 35% compared to 2019. 99% access social networks on a mobile device. 80% of the time (2 hours and 24 minutes) on social networks is spent on a mobile device. If we project our carbon/user impact to these data, we obtain 262 million Tons EqCO2 per year for the 4.33 billion mobile users, i.e. the equivalent of 0.61% of the EqCO2 impacts in the world in 2019 and more than half of France’s carbon emissions (56%).

In terms of the exchanged data, the bad guys are the news feeds of the Reddit, TikTok and Pinterest apps. The good students in terms of data exchanged are Youtube, Twitter and Twitch. Reddit consumes 32 times more data than the Youtube app.

The average established for the data exchanged is 32.93 MB for this use, or 71% more compared to the 2020 edition. Only 3 applications are above this threshold. Watch out for your data plans! Projection in 1 month, you will have consumed 142 Go!

Taking into account the average time spent on the social networks according to the Visionary Marketing blog: if you only use Tik Tok (up to 52 minutes per projected day), you will consume nearly 149 GB per month. While Instagram (up to 53 minutes per day) will make you consume 51 GB! Are you more into Facebook? It will make you consume nearly 19 GB (up to 58 minutes per day) per month.

Pour chacune de ses applications, mesurées sur un smartphone S7 (Android 8), le scénario suivant a été réalisé au travers de notre Greenspector Test Runner, permettant la réalisation de tests manuels sur une durée de 1 minute en one-to-one.

  • Launch the application (wait 20 seconds)
  • Scroll through the news feed or the “Discover” tab of the applications

Lydia vs Pumpkin

Reading Time: 3 minutes

For this first battle of 2021, we compare two payment applications between relatives: Lydia and Pumpkin. The advantage of these applications? Immediate repayment between friends in just a few clicks via a phone number. No more need to go through the traditional tedious steps of collecting an IBAN, adding it to a list of beneficiaries and the action of a transfer order (which will sometimes be received within 48 hours). Let’s find out together which application has the least carbon impact and the least consumption for your smartphone.

About Lydia: Created in 2011 this French fintech specializes in mobile payment and allows its users to pay and manage their money from the application.

About Pumpkin: Created in 2014 the French application offers payment between relatives and recently allows its users to take advantage of cashback.

The fight

All the spotlights are on the fighters, and the match can finally begin.

In the first part of the battle to measure the impact of the launch phase of the application, on this side, Lydia (0,104 g eqCO2) wins the first round by impacting 2% less than the Pumpkin application (0,106 g eqCO2).

During the second round which corresponds to the usage scenario, collecting a payment, Lydia takes the lead (0.181 g eqCO2) which leads against Pumpkin (0.314 g eqCO2) with a 42% lower carbon impact.

To put an end to this confrontation, we have set up two decisive rounds of observation of the rest phases of each opponent. If the Pumpkin application earns points by showing an 8% lower carbon impact for the foreground inactivity phase compared to Lydia, it is the most impacting on the background inactivity phase by 4%.

The bell rings, end of the match!

The winner

The Lydia app wins this match.

If we add the Carbon Impacts of all the scenarios measured, the Lydia application leads with a 26% lower carbon impact than the Pumpkin application.

Several answers can explain the differences in impact and energy and data consumption: Pumpkin presents several additional screens compared to Lydia:

  • Security screen at launch (pin code)
  • Contact directory synchronization pop-up during payment collection scenario
  • Animation during the confirmation of validation of the transaction
  • The news feed on the home page

For each of these applications, measured on an S7 smartphone (Android 8), the measurements were carried out through our GREENSPECTOR Benchmark Runner, allowing automated tests to be carried out.

Details of the scenarios:

  • Loading the application
  • Foreground application inactivity
  • Background application inactivity
  • User scenario: collecting a payment (30 seconds)

Each measurement is the average of 5 homogeneous measurements (with a low standard deviation). The consumption measured on the given smartphone according to a Wi-Fi type network can be different on a laptop PC with a wired network. For each of the iterations, the cache is first emptied.

To assess the impacts of infrastructures (datacenter, network) in the carbon projection calculations, we relied on the Greenspector methodology based on real data measured from the volume of data exchanged. This evaluation methodology takes into account the consumption of resources and energy in use for the requested equipment. As this is a very macroscopic approach, it is subject to uncertainty and could be refined to adapt to a given context, to a given tool. For the Carbon projection, we assumed a 50% projection via a Wi-Fi network and 50% via a mobile network.

To assess the impacts of the mobile in the carbon projection calculations, we measure the energy consumption of the user scenario on a real device and to integrate the material impact share, we rely on the theoretical wear rate generated by the user scenario on the battery, the first wearing part of a smartphone. 500 full charge and discharge cycles, therefore, cause a change of smartphone in our model. This methodology and method of calculation have been validated by the consulting firm specializing in eco-design, Evea.
