ITU-T L.1450 (12/2025)

منهجيات لتقييم الأثر البيئي لقطاع تكنولوجيا المعلومات والاتصالات

تشكّل التوصية ITU-T L.1450 جزءاً من سلسلة التوصيات ITU-T L.1400، وهي تتألف من جزأين:1)الجزء الأول: منهجية حساب بصمة قطاع تكنولوجيا المعلومات والاتصالات (ICT) من حيث الأثر البيئي على مدى دورة الحياة، بما في ذلك انبعاثات غازات الاحتباس الحراري (GHG)؛2)الجزء الثاني: منهجية تحديد ميزانية انبعاثات غازات الاحتباس الحراري بالنسبة لقطاع تكنولوجيا المعلومات والاتصالات مع مراعاة مسار درجتين مئويتين أو أقل.ويقدم التذييل IV مثالاً على البصمة الجزئية لقطاع تكنولوجيا المعلومات والاتصالات (ICT) المستمدة من الجزء الأول من التوصية. ويقدم التذييل X مثالاً على البصمة الكاملة لقطاع تكنولوجيا المعلومات والاتصالات.
