Pour chaque application, il est propos\u00e9 d'afficher le param\u00e8tre \u00ab Carbon Cost \u00bb, indiquant le niveau approximatif d'\u00e9missions de dioxyde de carbone dans l'atmosph\u00e8re et permettant d'\u00e9valuer comment le d\u00e9veloppement influence le r\u00e9chauffement climatique. <\/p>\n<p>Selon l'intervenant, m\u00eame si le logiciel libre est fourni gratuitement, il a un co\u00fbt indirect \u2014 l'impact du d\u00e9veloppement sur l'environnement. Par exemple, l'infrastructure serveur du projet, les serveurs d'int\u00e9gration continue, les activit\u00e9s de la fondation GNOME et l'organisation de conf\u00e9rences de d\u00e9veloppeurs n\u00e9cessitent de l'\u00e9lectricit\u00e9 et des mat\u00e9riaux, dont les processus de production entra\u00eenent des \u00e9missions de dioxyde de carbone dans l'atmosph\u00e8re. Les applications consomment \u00e9galement de l'\u00e9nergie sur les syst\u00e8mes des utilisateurs, ce qui a aussi un impact indirect sur l'environnement.<\/p>\n<p>L'introduction d'une nouvelle m\u00e9trique permettra de montrer le s\u00e9rieux du projet GNOME concernant la pr\u00e9servation de l'environnement. Parmi les facteurs pour le calcul de la m\u00e9trique, on mentionne le temps de fonctionnement de l'application, la charge sur le CPU, le stockage et le r\u00e9seau, ainsi que l'intensit\u00e9 des tests dans le syst\u00e8me d'int\u00e9gration continue. Pour \u00e9valuer la charge, il est propos\u00e9 d'utiliser sysprof, les m\u00e9canismes de comptabilit\u00e9 systemd et powertop, dont les donn\u00e9es peuvent \u00eatre converties en \u00e9quivalent d'\u00e9mission de dioxyde de carbone. Par exemple, 1 heure de charge intensive du CPU peut \u00eatre \u00e9valu\u00e9e \u00e0 environ 6 grammes <noindex><a rel=\"nofollow\" href=\"https:\/\/en.wikipedia.org\/wiki\/Global_warming_potential\">CO2e<\/a><\/noindex> (en se basant sur une augmentation de la puissance consomm\u00e9e de 20 W), et 1 Go de donn\u00e9es t\u00e9l\u00e9charg\u00e9es par r\u00e9seau \u00e0 17 grammes CO2e. En ce qui concerne les syst\u00e8mes d'int\u00e9gration continue, la compilation de Glib est \u00e9valu\u00e9e \u00e0 48 kilogrammes CO2e par an (pour comparaison, une personne produit environ 4,1 tonnes de CO2e par an).<\/p>\n<p>Pour r\u00e9duire le \u00ab Carbon Cost \u00bb, il est propos\u00e9 aux d\u00e9veloppeurs d'effectuer des optimisations, telles que l'application de la mise en cache, l'am\u00e9lioration de l'efficacit\u00e9 du code, la r\u00e9duction de la charge r\u00e9seau et l'utilisation d'images pr\u00e9d\u00e9finies dans le syst\u00e8me d'int\u00e9gration continue, contribuant ainsi \u00e0 la lutte contre le r\u00e9chauffement climatique. Par exemple, l'utilisation d'images Docker pr\u00eates \u00e0 l'emploi dans le syst\u00e8me d'int\u00e9gration continue permettrait de r\u00e9duire la valeur de la m\u00e9trique par 4. <\/p>\n<p>Pour chaque version majeure, il est propos\u00e9 de calculer le \u00ab Carbon Cost \u00bb total, qui additionne les m\u00e9triques de toutes les applications ainsi que les co\u00fbts du projet GNOME, de la fondation GNOME, des hackfests et du syst\u00e8me d'int\u00e9gration continue. Une telle m\u00e9trique permettra de conduire le d\u00e9veloppement en tenant compte de l'impact sur l'environnement, de suivre la dynamique et de proc\u00e9der aux optimisations
