The reference card is a clearly defined description of model features. The numerous options have been organized into a limited amount of default and model specific (non default) options. In addition some features are described by a short clarifying text.

Legend:

  • not implemented

About

Name and version

IPETS 2.0

Institution and users

National Center for Atmospheric Research (NCAR), USA, https://www2.cgd.ucar.edu/sections/tss/iam/iam-modeling.

Model scope and methods

Model documentation: Model scope and methods - IPETS

Objective

The iPETS model is developed to analyze greenhouse gas mitigation and climate change impacts with a special emphasis on the implications of demographic heterogeneity.

Concept

Computable General Equilibrium

Solution method

The economic problem is formulated as a three-level nested problem. The solution of these three sub-problems yield the dynamic capital path (investment/consumption trade-off in each simulation year), and factor and output prices which clear all factor and goods markets.

Anticipation

Forward looking

Temporal dimension

Base year:2004, time steps:annual, horizon: 2100

Spatial dimension

Number of regions:9

  1. China
  2. EU27+
  3. India
  4. Latin America
  5. Other Developing Countries
  6. Other Industrialized Countries
  7. sub-Saharan Africa
  8. Transition Countries

Policy implementation

Climate policy through (global or regional) carbon tax or emission target (annual level or temporal budget)


Socio economic drivers

Model documentation: Socio-economic drivers - IPETS

Exogenous drivers

  • Exogenous GDP
  • Total Factor Productivity
  • Labour Productivity
  • Capital Technical progress
  • Energy Technical progress
  • Materials Technical progress
  • GDP per capita

Note: Exogenous GDP paths are targeted for baseline scenarios by modifying labor productivity. In mitigation and impacts analyses GDP is endogenously determined.


Development

  • GDP per capita
  • Income distribution in a region
  • Urbanisation rate
  • Education level
  • Labour participation rate
