However, this does not drastically reduce the environmental impact of concrete,&nbsp;<a href=\"https:\/\/journal.augc.asso.fr\/index.php\/ajce\/article\/view\/2859\" target=\"_blank\" rel=\"noreferrer noopener\">and so a broader reflection on resource efficiency<\/a> would be beneficial.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-red-color has-text-color has-link-color wp-elements-66a42d76bc707eb3310551b839ad7c89\">Environmental impacts of digital infrastructure<\/h2>\n\n\n\n<p>The digital transition is often perceived as beneficial to the environment, offering increased productivity of technical systems and resource efficiency. However, the environmental impacts of digital services remain poorly understood and are frequently overlooked. Despite their intangible nature, digital services depend on very real flows of materials and energy.<\/p>\n\n\n\n<p>For exemple,&nbsp;<a href=\"https:\/\/hal.archives-ouvertes.fr\/hal-03366617\" target=\"_blank\" rel=\"noreferrer noopener\">the environmental impact of a bridge monitoring system equipped with sensors<\/a>&nbsp;was estimated. The functional unit was defined as one day of monitoring. The analysis took four subsystems into consideration: data acquisition; data transfer and communication; data consultation; and data storage.<\/p>\n\n\n\n<p>Initial results showed that when data is stored for a short period (1 day), impacts are dominated by the production of display screens and the electricity used for data transfer and processing. However, as the data storage duration increases, this phase becomes the primary source of impact.<a href=\"https:\/\/ingenius.ecoledesponts.fr\/articles\/analyse-du-cycle-de-vie-episode-3-3\/#7ec60def-340b-4e4a-a636-6efe33ca75ab\"><sup>1<\/sup><\/a> According to the assumptions made in this case study and available data on servers, storing data for 10 years results in approximately 430 kg CO\u2082 eq. emitted per day of monitoring. To put this into perspective, the emissions from producing 1 m\u00b3 of concrete, range from 120 to 280 kg CO\u2082 eq., depending on the type and quantity of cement used.<\/p>\n\n\n\n<p>To go further, it would be interesting to compare this system with the monitoring of a traditional, non-instrumented bridge, which would require more frequent on-site inspections to achieve the same level of quality in structural surveillance. These results highlight the importance of smart data management as the volume of digital data continues to increase.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong><a href=\"https:\/\/ingenius.ecoledesponts.fr\/en\/articles\/life-cycle-assessment-a-historic-background\/\" target=\"_blank\" rel=\"noreferrer noopener\">Read Episode 1: Life Cycle Assessment &#8211; History<\/a><\/strong><\/p>\n\n\n\n<p><strong><strong><a href=\"https:\/\/ingenius.ecoledesponts.fr\/en\/articles\/life-cycle-assessment-methodology\/\" target=\"_blank\" rel=\"noreferrer noopener\">Read Episode 2: Life Cycle Assessment &#8211; Methodology<\/a><\/strong><\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><a href=\"https:\/\/link.springer.com\/chapter\/10.1007\/978-3-031-25182-5_56\" target=\"_blank\" rel=\"noreferrer noopener\">M.
