G-Cubed model 20R

Table of contents

The 20R model is a hybrid of the 2R and the 20U models.

Regions

Like the 2R model the regions are symmetric. They include:

  1. United States (USA)
  2. Rest of World (ROW) set up so that the data for the rest of the world is identical to the data for the United States

Sectors

Like the 20C model, each region aggregates production into the same 20 sectors. These sectors are aggregations of the 65 sectors defined in the GTAP database. All 20 sectors are listed below:

  1. Electricity distribution
  2. Gas extraction and utilities
  3. Petroleum refining
  4. Coal mining
  5. Crude oil extraction
  6. Construction
  7. Other mining
  8. Agriculture and forestry
  9. Durable goods
  10. Nondurable goods
  11. Transportation
  12. Services
  13. Coal generation of electricity
  14. Natural gas generation of electricity
  15. Petroleum generation of electricity
  16. Nuclear generation of electricity
  17. Wind generation of electricity
  18. Solar generation of electricity
  19. Hydroelectric generation of electricity
  20. Other generation of electricity

13 of the 20 sectors articulate the production and distribution of the energy required to drive economic activity and the resulting greenhouse gas emissions.

Sector 1 captures the distribution of electricity. Sectors 13 to 20 split electricity generation by type of energy source, enabling detailed analysis of shifts in fossil-fuel dependency. Sectors 2 to 5 captures fossil-fuel extraction and processing for coal, gas, and oil. The 7 non-energy sectors capture all other types of production.

The full set of 20 sectors provide detailed understanding of energy dependencies for each region while also differentiating the regions in terms of economic specialisation.

Note that the GTAP electricity sector is split into the various electricity generation sectors based on GWH electricity production shares. Those generation sectors are then aggregated into the electricity distribution sector.

Electricity generation sectors

The endowment and factor inputs of the GTAP electricity sector is split across the electricity generation sectors in proportion to the gigawatt-hours (GWh) of electricity production by generation type for each country used to allocate electricity sector emissions among electricity generation sectors. Data on electricity production is sourced from Ember Climate.

Carbon dioxide emissions

Carbon dioxide emissions are associated with the usage of fossil fuels in the production process across all sectors. They depend on the scale of output from each sector and the fossil-fuel intensities of each sector.
