Environmentally-Extended Input-Output Model of South Korea (KREEIO)

Background

KREEIO (v1.0) is the first milestone of an ongoing effort to build high-quality, high-resolution environmentally-extended input-output (EEIO) models for South Korea. The main goal of the effort is to 1) strengthen environmental input-output analysis and modeling in South Korea, and 2) provide important data for other countries or multi-national companies that import from South Korea for estimating the environmental footprint of their products along the supply chain. KREEIO will be regularly updated to include more recent economic and greenhouse gas data and cover more environmental aspects, such as criteria air pollution, resource consumption, and waste generation.


Version

KREEIO (v1.0) was released on Jan 28, 2022, and

  • focuses on GHG emissions, with results expressed in MT CO2e per million US dollar

  • reflects the economic and environmental conditions of year 2017

  • covers 381 sectors (aggregated to 373 sectors, among the highest sectoral resolutions)

  • was peer reviewed and published in a top scientific journal

See the reference below for details on how KREEIO (v1.0) was created.

Data sources

Three main data sources were used to develop KREEIO:

  • an Input-Output table, provided by the Economic Statistic System under the Bank of Korea

  • an energy balance table, provided by the Korean Energy Statistical Information System under Korean Ministry of Trade, Industry and Energy

  • a GHG inventory, compiled by the Greenhouse Gas Inventory and Research Center under Korean Ministry of Environment

Additional information

KREEIO (v1.0) was developed primarily by Dr. Yi Yang in collaboration with Ms. Yujin Park and Dr. Hung-Suck Park. The project was partially supported by the National Research Foundation of Korea. At the time of model development, Dr. Hung-Suck Park was a professor at University of Ulsan with research focused on eco-industrial parks and Ms. Yujin Park was his PhD student.
