Digital & Ecological Transition Webinar #2
|
In addition to the control and reduction of the direct impacts of the digital sector (production impacts, operating impacts), discussed in the webinar on October 18, specialists and decision-makers are looking at the potential of digital technologies, as vectors of information for optimizing the operation of machines, or influencing consumer behavior, to accompany, drive or even accelerate the reduction of the direct impacts of other economic sectors.
A number of reports and studies have been published, but it is clear that characterizing this potential is more difficult than estimating direct impacts.

In this second webinar, we'll take a look at a few examples of activities made possible by digital technology: car-sharing, teleworking, videophony. We'll then discuss the difficulty of posing the problem of impact reduction in its generality, and the associated methodological problems, with our guests:
|
- Jérémie Almosni, Ile de France Director of Ademe, will talk about the emissions reductions made possible by teleworking,
- Aina Rasoldier, researcher at Grenoble Alpes University, will talk about the potential of car-sharing to reduce emissions from home-to-work transport,
- Danilo Carastan, researcher at Grenoble Alpes University, will talk about emissions reductions made possible by virtual scientific conferences,
- Hugues Ferreboeuf (1986 ) , Project Director of the Shift Project, will talk about the work of the European Green Digital Coalition (Home) in identifying decarbonizing digital solutions,
- Zénon Vasselin and Clara Benedini, from Carbone 4, will talk about the methodological precautions to be taken when quantifying avoided emissions.

Climate change is very much in the news! And digital technology and its new services are often put forward as assets that can help meet the objectives of the Paris Agreements.
In practice, however, the situation is not quite so simple. When it comes to analyzing the impact of digital technology on the environment, and in particular its contribution to reducing greenhouse gas emissions, we need to distinguish between two types of effect:
- direct effects, i.e. the energy consumption and CO2 production of networks, terminals, data centers, etc., not only during their periods of operation, but also throughout their lifecycle, from production to final dismantling (taking into account recovery possibilities, etc.).
- indirect effects, linked to digital substitution and the digitization of existing processes or systems, theoretically enabling savings in greenhouse gas emissions generated by traditional behaviors, e.g. videoconferencing replacing business travel, telecommuting reducing commuting...
The analysis must therefore be global, integrating the two types of effect, with the added difficulty (known as the rebound effect) that the development of substitution offers, as well as increased network performance, inevitably lead to a multiplication of uses and the number of terminals, and therefore to an increase in network capacity to handle the additional traffic, aggravating the direct effects.

To explore these issues in greater depth, the Télécom Paris alumni "Networks & Services" and "Digital & Environment" groups are organizing two webinars on the theme of "Digital and Ecological Transition".
