Ⅰ. Case Study with Integrated Analysis Toolkit for Carbon Absorption and Storage
1. Background and scope of analysis
o In preparation for a successful transition to a carbon-neutral society by 2050, this study develops the integrated analysis toolkit for carbon absorption and storage to evaluate the carbon absorption, storage, and value of the ecosystem services scientifically and objectively.
ㅇ The 2016 study laid the foundation for toolkit development to link the quantitative environmental impact assessment and environmental unit values, and the 2021 study completed the development of the toolkit after much improvement and stabilization.
- This year’s study aims to support the policy decision-making for achieving carbon neutrality by assessing and renewing the carbon absorption and storage capacity of ecosystems measured in 2019 to estimate its economic value using the ecosystem types and the carbon absorption and storage coefficients of the ecosystem established in the 2016 study.

2. Impact analysis
o As of 2019, the ecosystems stored 950 million tons of carbon and absorbed 15 million tons of carbon per year, with carbon storage reduced by 1% and carbon absorption increased by 1% compared with 2007.
ㅇ As of 2019, forests, a major carbon sink, stored 790 million tons and absorbed 15 million tons of carbon per year. Although forests shrank by 3% compared with 2007, the carbon storage and absorption rose by 2% and 1%, respectively, following a 76% increase of the broad-leaf forest area with high carbon absorption and storage coefficient.
ㅇ As of 2019, the regions with
