The trend of low carbon is driving multi pathways to reduce greenhouse gases ( GHG) emission.One of the pathways is development and application of advanced steels such as advanced electrical steel and high strength steel etc,which simultaneously pushes green economy growth forward and reduces GHG emission in products lifecycle.For investigating a best practice,China Steel Corporation ( CSC),Tatung Motor Co.,ITRI and MIRDC had cooperated for a life cycle assessment ( LCA) study of 3HP general motor on 2010.LCA study for three kinds of motors was conducted,respectively,with electrical steel ( ES ) 50CS290,50CS400 and 50CS1300,and the GHG reduction benefit with advanced ES was quantified.For MRV rule.life cycle GHG emission reporting of 50CS290,50CS400,50CS1300 and premium 3 - HP motor were completed for third - party ( DNV) verification with PAS 2050.The results show that advanced electrical steel (50CS290 and 50CS400) improve motor s efficiency which is beneficial for energy saving and GHG reduction.Advanced electrical steel (50CS290) taking the place of 50CS1300 is result in increasing motor efficiency 2.89 0-10.The GHG mitigation in life cycle 20 years is 31 times the GHG emissions of cradle to gate for a 3HP motor.On the other hand,production of I tonne advanced ES 50CS290 for advanced 3HP motors approximately mitigates 300 tonnes C02e in life cycle.
