The direct energy footprint of digital technology is growing rapidly. The explosion of uses and the multiplication of frequently renewed digital peripherals are the main factors of inflation.
While the Citizens' Climate Convention is proposing a set of proposals to "accompany the evolution of digital technology to reduce its environmental impact", the Senate mission on the environmental footprint of digital technology presented its diagnosis and a series of recommendations on June 24. The same week, the I-Num group of experts presented a calculation of these environmental impacts.
The Senate's information mission pleads for "an ecological digital transition
The Senate information mission on the environmental footprint of digital technology presented its roadmap for "an ecological digital transition" on June 24.
Based on an unprecedented study assessing the carbon footprint of digital technology in France, it makes 25 proposals concerning both equipment and usage. Several of these proposals are aimed at local authorities, including integrating environmental issues into their digital strategy, contributing to the reuse market via public procurement, and encouraging the establishment of data centers in France, by focusing on their complementarity with renewable energy sources.
For the information mission, "the reduction of the carbon footprint of digital technology in France should (...) particularly involve limiting the renewal of terminals, while the lifespan of a smartphone is now 23 months.
"This is not only an environmental imperative, but also an economic one: by moving away from the disposable model - which is fueled by imports that are a burden on the country's trade balance - to a circular model - based on an industrial ecosystem capable of offering reconditioned terminals and repair solutions - public policies can promote the sustainable creation of jobs that cannot be relocated and are located in the regions.

The Citizen's Convention's ideas for reducing the environmental impact of digital technology
The Citizens' Climate Convention reaches similar conclusions: it will be impossible to reduce greenhouse gas (GHG) emissions by at least 40% by 2030 (compared to 1990) without reducing the carbon footprint of digital technology.
Among the 149 proposals adopted by the Citizens' Convention, the proposal "Supporting the evolution of digital technology to reduce its environmental impact" was adopted by 98% of the 150 citizens selected by lot and representative of society,
"The reduction of digital consumption is one of the ways to obtain a considerable reduction of greenhouse gas emissions, as it represents in emissions 2 to 3 times the carbon footprint of a country like France. This phenomenon is mainly linked to the manufacturing of equipment and software as well as to their use with the storage and circulation of data. The impossibility of reaching our objectives without reducing the carbon footprint of this sector seems obvious. Moreover, we must take into account that the quantity of minerals to manufacture digital equipment is limited in nature. For a large part of these raw materials, total depletion is expected within 30 years.Finally, in people's minds, digital technology is immaterial and can be used indefinitely. Fashion effects encourage us to renew our digital devices very quickly, while their life cycle is very high in greenhouse gas emissions.
To this end, it formulates a series of tracks:
Systematize the ecolabels on all digital equipment;
Promote information and education on digital sobriety practices;
Make the carbon neutrality commitments of digital players accessible to consumers;
Reduce the needs of digital services through their eco-design in several directions: components, software, energy consumption, use of heat produced, design of services and offers; and make mandatory by regulation the eco-design of websites and online public services of companies;
Make data centers more virtuous by requiring the recovery of the heat they produce for redistribution and reduce their consumption by relocating data centers (perhaps by city/neighborhood/borough) and by ensuring decarbonized energy consumption by data centers In this sense, it is important to encourage a design of data centers that is in line with the logic of carbon reduction;
Progressively develop the mutualization of digital services when relevant for an efficient digital sobriety and thus limit the proliferation of connected devices and exponential data storage.
More broadly, we must regain the ability to ask ourselves individually and collectively about our needs: do we need so much electronic equipment and to change it so often? Do we need 5G?

iNUM: a study to quantify the environmental impacts of digital technology in France
Carried out by a group of independent experts between January and June 2020, this study, called "iNum", aims to quantify the environmental impacts of digital technology in France and to identify courses of action adapted to French specificities. The study is based on a Life Cycle Assessment (LCA) methodology.
Preliminary results of the study indicate that digital represents, nationwide, the equivalent of :
Energy consumption: 180 TWh of primary energy;
Global warming: 24 million tons of greenhouse gases;
Fresh water tension: 559 million m3 of fresh water;
Depletion of abiotic resources: 833 tons of antimony equivalent.
Compared to the annual environmental impacts of France, this represents the equivalent of :
Primary energy: 6.2% of France's consumption
Greenhouse gases: 5.2% of France's emissions
Water: 10.2% of France's consumption
Resources: excavation of 4 billion tons of soil.
A large part of these impacts are "imported": they mainly take place outside France, during the manufacturing of the equipment.
Taking these "invisible" impacts into account is essential to build an effective action plan. The manufacture of the equipment accounts for between 36% and 87% of the environmental impact (depending on the indicator observed).
Networks are responsible for 5-21% of our digital footprint and data centers for 4-15% of the impacts.
Recommendations" First of all, it is essential to properly inform French people about their digital footprint to make them be more reasonable in their daily uses and to adopt really efficient gestures. Deleting emails is not enough. It is especially necessary to manufacture fewer devices that last longer.
The group of experts thus recommends, as a priority, to :
Increase the lifespan of equipment by extending the legal warranty period, promoting repair and reuse, and prohibiting economic and technical mechanisms that artificially accelerate the obsolescence of consumers' equipment.
Reduce the amount of digital resources mobilized (equipment, networks, etc.), in particular by encouraging the pooling of equipment, by eco-designing digital services (see below), by reducing the number of very large screens and connected objects.
Giving back control to users, including allowing them to choose the software updates they want to install and guiding them towards repairable and easily refurbished equipment by strengthening the requirements of the repairability index when it becomes a durability index and by increasing environmental labelling obligations, especially for online services.
Eco-designing digital services to reduce their digital resource requirements and thus promote the extension of the lifespan of devices as well as their re-use.
Beyond the environmental impacts, "we must be aware that digital is a critical resource. And that the stock of this resource is inevitably depleting because it is not renewable.
The expert collective is submitting these preliminary results for review and will produce final results in October 2020.
