Types of integrated assessment analyses:

E. Kriegler: Insights from the model MIND, CDMC seminar, July 12, 2006
Use conventional (neo-classical) climate – macroeconomic growth models (e.g. DICE) as reference point
Keep it as simple as possible by adding most important processes step by step
Construct hierarchy of models for
→ tracking model behaviour in enlarging parameter space
→ identifying benchmarks (ideal worlds) as reference models
Model philosophy

E. Kriegler: Insights from the model MIND, CDMC seminar, July 12, 2006
Exogenuous assumptions about growth of energy and labour productivity
→ unable to model effect of investment decisions on growth dynamics (both in BAU and climate policy case)
Model solution: → include energy as factor of production→ include R&D sectors for improving energy and labour productivity
First improvement: R&D sectors

E. Kriegler: Insights from the model MIND, CDMC seminar, July 12, 2006
Competing energy technologies with qualitatively different dynamics
→ renewables experience large learning rates
→ fossil fuel use will be limited by resource base
Model solution: → separate energy sector into renewable and fossil fuel sector→ include learning-by-doing and resource scarcity
Second improvement: Energy sector

Carbon capturing and sequestration has become an important option to neutralise climate impact of fossil fuels
Model solution: → include CCS sector (Nico Bauer, Ph.D. Thesis, download at opus.kobv.de/ubp/volltexte/2006/654/pdf/bauer.pdf)
5 capturing techologies: low cost, post-combustion (coal, cement, iron), oxyfuel/syngas
models for transportation (pipelines), compression, injection
6 sequestration sites: oil & gas fields (166 GtC), trapped aquifers (55 GtC), untrapped aquifers (3500 GtC); onshore or offshore
Third improvement: CCS
