In order to limit global warming to 1.5°C, countries must submit its 2035 Nationally Determined Contribution(NDC) target to the United Nations by 2025. This database sets Korea’s 2035 NDC target based on the scientific emission allowance called the carbon budget and shows the emission reduction path to net-zero by 2050. A key feature of this database is its ability to present results derived from various methodologies and assumptions. It also aims to contribute to the international community’s efforts to address climate change by considering the feasibility of emission reduction targets.
