Summaryy

Korea Government have a plan to join the 20 by 20 CCS Project which p j y jwill be selected on 2010 G8 Extended Summit meeting

Korea Government proposed three scenarios to cut it’s C02 emission by 2020 final reduction target will be confirmed by the end of this year2020 , final reduction target will be confirmed by the end of this year through a national consensus.

KEPEI and KOSEP would like to install the Demonstration of Carbon Capture and Storage Readiness for coal fired power plants by 2015(100MW) in Young Dong Power Plant.
