Aujourd’hui le RFF (r\u00e9seau ferr\u00e9 Fran\u00e7ais), la SNCF et l’ADEME (Agende De Environnement et Ma\u00eetrise de l’Energie) ont profit\u00e9 de la construction d’une nouvelle ligne grande vitesse pour calculer le bilan carbone global.
\nOnt ainsi \u00e9t\u00e9 pris en compte dans le calcul la construction de deux nouvelles gares, de 30 rames TGV et des installations de maintenance.
\nA partir de ses donn\u00e9es, compl\u00e9t\u00e9es par les \u00e9missions de gaz inh\u00e9rentes \u00e0 l’exploitation commerciale du syst\u00e8me pendant 30 ans, il ressort que pas loin de 2 millions de tonnes \u00e9quivalent CO\u00b2 seront ainsi rejet\u00e9es pendant ce cycle.
\nDe cette masse on peut r\u00e9partir les \u00e9missions comme suit : 53% seront issus de l’\u00e9nergie de traction et 42% des travaux d’infrastructure.<\/p>\n
L’analyse compl\u00e8te indique qu’apr\u00e8s 12 ann\u00e9es d’exploitation le bilan \u00e9cologique est globalement neutre.
\nAttention ce calcul ne peut toutefois pas \u00eatre \u00e9tendu par simple translation \u00e0 d’autres pays, la France poss\u00e9dant une caract\u00e9ristique majeur celle de produire 95% de son \u00e9lectricit\u00e9 \u00e0 partir d’\u00e9nergie nucl\u00e9aire.<\/p>\n
