As part of a portfolio of actions, CCS accounts for 14% of total energy-related CO2 reductions needed by 2050. • 我國2013年總排放量 250Mt ，2020年CO2 排放量需回到2005 年排放量 ，能源政策提出節能、 淨煤…等行動方案，至2020年仍有47.7 Mt 缺口 ，低GHG的能源 技術(ex.

The remaining 20% are emitted from industrial sources, mainly cement production plants (~7% of the total emission), refineries (~6%) and iron and steel industry (~5%). The CO2 concentration in flue gas and the average emission per source can be higher than in power plants. • Postcombusti
