Model Type: Set of 14 multi-sector regional CGE models. Regional models may be run independently or as a system for international trade in emissions permits. Regional models are dynamic-recursive, with a time frame of 1990 through 2050 in five-year time steps.
Developer/Home Institution: Pacific Northwest National Laboratory/Joint Global Change Research Institute at the University of Maryland. Contacts: Ron Sands (Ronald.Sands@pnl.gov) or Hugh Pitcher (Hugh.Pitcher@pnl.gov)
Sector Detail: Agriculture (primary agriculture, food processing); services; energy production (oil, natural gas, coal); energy transformation (coke, electricity, refined petroleum, gas distribution); energy-intensive industries (paper and pulp, chemicals, cement, iron and steel, non-ferrous metals, other industry); transportation (passenger transport, freight transport)
Regional Detail: 14 regions (United States, Canada, Mexico, Western Europe, Eastern Europe, former Soviet Union, China, India, Brazil, Japan, South Korea, Australia/New Zealand, Middle East, Rest of World)
Technology Detail: Each production process is represented by a CES or Leontief production function. Electricity sector is broken into subsectors (oil-fired, gas-fired, coal-fired, hydro and renewables, nuclear).
Special Features: Many of the regional models are developed jointly with analysts from that region. Capital stock is segmented into five-year vintages by sector; elasticity of substitution between inputs is greater for new capital than for old capital vintages. Hybrid input-output tables are constructed for consistency with base-year energy balances.
