The Republic of Korea hereby communicates its updated NDC that incorporates progress and improvements in its national climate policies in accordance with paragraph 24 of decision 1/CP.21 so as to contribute to the faithful implementation and achievement of the goals of the Paris Agreement. The updated NDC is set at the most ambitious level possible, considering the long-term temperature goal set out in Article 2 of the Paris Agreement. The updated target is to reduce 24.4% from the total national GHG emissions in 2017, which is 709.1 MtCO2eq, by 2030. This is an absolute emissions reduction target that is more predictable and transparent than the target relative to Business-As-Usual (BAU) emissions projection in the previous first NDC.
