Nitrous Oxide, Hydrofluorocarbons, Perfluorocarbons, Sulfur hexafluoride Methodologies and tools to estimate GHG emissions and data - 2006 IPCC Guidelines for National Greenhouse Gas Inventories, IPCC Inventory Software - Long-range Energy Alternatives Planning System (LEAP) - Greenhouse gas Abatement Cost Model (GACMO) - Multi-Criteria Assessment (MCA) - IPCC SAR GWP values (Carbon Dioxide; 1, Methane; 21, Nitrous Oxide; 310) Planning process The INDC has been prepared by a participatory and transparent process through stakeholder consultations, taking into consideration the national socio-economic development plans, including the five-year strategy for national economic development Business-As- Usual scenario (BAU) DPR Koreaâs BAU scenario for GHG emissions was developed based on the assumption of economic growth in the absence of climate change policies. - GHG emission projections for 2020: 116.36 million tCO2 e - GHG emission projections for 2030: 187.73 million tCO2 e The BAU scenario projection will be revised to include more accurate information with preparation of the National Communications and Biennial Update.Intended Nationally Determined Contribution of Democratic Peopleâs Republic of Korea Page 5 Unconditional contribution Based the on national circumstances, common but differentiated responsibility and its capability, DPR Korea will reduce GHG emissions by 8.0% compared to BAU scenario, by 2030 with domestic resources.
