صافي الانبعاثات الصفري | NET-ZERO EMISSIONS

ما هو صافي الانبعاثات الصفري؟

مصطلح يشير إلى التوازن بين انبعاثات غازات الدفيئة المُنتجة والانبعاثات التي تتم إزالتها من الغلاف الجوي. ويتم تحقيق صافي الانبعاثات الصفري من خلال تخفيض الانبعاثات الناتجة عن النشاطات البشرية مثل احتراق الوقود الأحفوري والمصانع وغيرها إلى أقرب حد ممكن من الصفر. بالإضافة إلى موازنة الانبعاثات المتبقية مع كمية مكافئة من الانبعاثات التي تتم إزالتها بطرق مختلفة مثل تشجير الغابات أو الاعتماد على الطاقات المتجددة.

يُعد تحقيق صافي الانبعاثات الصفري أمراً في غاية الأهمية نظراً لكونه الطريقة الأفضل لمواجهة التغير المناخي والحد من آثار ظاهرة الاحتباس الحراري. وبموجب اتفاقية باريس وافقت الدول على الحد من ارتفاع درجات الحرارة الناتج عن تلك الظاهرة إلى ما دون 2 درجة مئوية وبشكل مثالي 1.5 درجة مئوية. وذلك من خلال الوصول إلى صافي انبعاثات صفري بحلول عام 2100.
