In December 2021, the Republic of Korea submitted an updated emission reduction target to UNFCCC, scaling up the absolute emissions reduction target from 709.1 MtCO2eq to 727.6 MtCO2eq, which is equivalent to the 40% reduction from the total national GHG emissions in 2018. (Previously reduction target of 709.1 MtCO2eq corresponds to a 24.4% reduction from the 2017 level) In line with its previous target, the updated target (2021) is more predictable and transparent than the target relative to Business-As-Usual (BAU) emissions projection in the previous first NDC.
