Environmentally-Extended Input-Output Model of Singapore (SGEEIO)

Version

SGEEIO (v1.0)

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

• reflects the economic and environmental conditions of year 2015

• covers 105 sectors

Data sources

TWO main data sources were used to develop SGEEIO: 

• an Input-Output table, provided by Singapore's Department of Statistics

• a GHG inventory, extracted from the Fourth Biennial Update Report submitted to the UNFCCC prepared by Singapore's National Environmental Agency

Additional information

There is an expanded version that dis-aggregates the electronic sector into several subsectors — like semiconductors, computers, and computer storage — based on South Korea's EEIO model. You may also request this expanded model if interested.
