Description of model

TIAM (TIMES Integrated Assessment Model) comprises several thousand technologies in all sectors of the energy system.  It is therefore most relevant to assessing the possibilities for technological solutions to reducing emissions of greenhouse gas emissions.  This includes policy aimed at stimulating the development of new technologies and creating the conditions for the adoption of these technologies.

The model is characterized by several technical and economic parameters and by emission coefficients for the three main GHG’s: CO2, CH4, and N2O. The following mitigation options are available in the model:

  1. energy and technology substitution;

  2. demand reduction;

  3. specific CH4 and N2O options;

  4. biological absorption of CO2;

  5. capture (electricity and hydrogen) and sequestration of CO2 (CCS).  Outputs from the model include the rate of adoption of new technologies and subsequent emission levels.

Particular relevance

The model is relevant to investigating the development of new 'greener' energy technologies and looking at the conditions for the adoption of these technologies.

Model applications

Analysis of climate policies under uncertainty with TIAM and the new climate module. The objective of this paper is to use TIAM to assess the feasibility, cost, and means of maintaining global temperature increase within the  2 ºC to 3ºC range (long term), under high economic and climate uncertainty ( strategies_TIAM_stuttgart_nov2006.pdf)

The Role of Nuclear Energy in Long-Term Climate Scenarios: An Analysis with the World-TIMES Model - Most of the emission scenarios of IPCC show an important role for nuclear energy to satisfy energy demand in the long term. The authors' objective is to analyze the role of nuclear energy in long-term climate scenarios using the World-TIMES bottom-up model. (

Organization's main area of research
