Outline of Integrated Assessment Model DNE21
RITE has developed Dynamic New Eath 21 (DNE21) model and the family models with Professor Kenji Yamaji and Associate Professor Yasumasa Fujii of the University of Tokyo. We also have analyzed and evaluated global warming mitigation strategies using the developed model, in order to make the best possible quantitative analysis and assessment in terms of energy, environment, economy, and various other aspects from a long-term and global point of view.
The Integrated Assessment Model DNE21 which consits of Energy Systems Model, Macro-economic Model and Climate Change Model is introduced below.
Type of DNE21 Model
- Dynamic non-linear optimization type
- Modeling energy technologies on the supply side and CO2 capture and sequestration technoglogies by "bottom-up" approach
- Modeling energy technologis of the end-use by "top-down" approach
Evaluation Time Span of DNE21 Model
- 100 years between 2000 and 2100 (150 years up to 2150 for optimization)
- 10 years step up to 2050, and thereafter 25 years step
World Region Division of DNE21
- 10 world regions
- Interregional transportation of energy & CO2 and CO2 emission trading among the 10 regions are taken into account.
- Integrated Assessment Model DNE21 consists of 3 modules of the energy systems, the macro economic and the climate change models.
- The 3 models are hard-linked.
The detail of each model can be seen by a click in the above picture.
