The general framework is a multi-sector, multi-region, computable general equilibrium (CGE) model of the world economy. It utilizes the GTAP dataset (maintained at Purdue University) that includes input-output relationships among sectors within a broader social accounting matrix that includes exports, imports, government, investment and household demand for final goods, and the ownership and supply to each sector of labor, capital and natural resources.
The standard economic specification of the model in billions of dollars of inputs (capital rents, labor, resource rents) and outputs (gross output of each sector and output supplied to each final demand sector) is augmented with accounts in physical terms on energy (exajoules), emissions (tons), land use (hectares), population (billions of people), natural resource endowments (exajoules, hectares) and efficiencies (energy produced/energy used) of advanced technology.
These supplemental physical accounts translate economic accounts (in billions of dollars) to corresponding estimates of physical depletion and use of natural resources, technical efficiencies of energy conversion processes and against limits of annual availability of renewable resources such as land availability, and the number of people affected to consider health effects.
