摘要

隨著經濟的成長，建築材料如水泥和混凝土的需求不斷提高，此現象在新興經濟體尤其明顯。全球水泥生產過程中CO2排放量約占全體人為CO2排放總量的8％，或占全體人為溫室氣體排放總量的6％，因此水泥業在CO2減量方面面臨嚴峻的挑戰。水泥業為能源使用密集的產業，企業必須採取措施，從製程、燃料使用和產品的最終用途，以減少碳足跡並同時降低其碳排放強度。本文主要分析水泥產業的產銷及能源使用現況並提出水泥業溫室氣體減量方案，包括提升旋窯熱效率、增加生質物的使用、提升用電效率、發展碳捕獲與封存、提高水泥使用效率以及提高水泥添加劑比例。

As economies grow and get wealthier, the demand for construction materials such as cement and concrete is booming. This is particularly visible in emerging economies. Cement production contributed to roughly 8% of worldwide anthropogenic CO2 emissions or 6% of total anthropogenic greenhouse gas emissions. The global cement industry is facing the challenge to sustain its business while decreasing its carbon intensity, from production processes, fuel uses and its product end use. The cement companies around the world must take steps to reduce their carbon footprint today, both in emerging economies and industrialized countries. The solutions proposed in this paper can help the industry move in the right direction, set targets and take action that will lead to deep greenhouse gas emission reductions.
