The development of a World Integrated assessment Model of Technology-Economy-Climate change for the investigation of the impact of induced technical and behavioural change on the environment

Final Activity Report Summary - WIATEC (The development of a World Integrated assessment Model of Technology-Economy-Climate change for ... induced technical and behavioural change on the environment)

The aim of the project was to build a simple and highly aggregate theoretical and empirical model of technology, economy and climate change linkage. The model was to capture the essential elements of the relationship between economic and environment variables such as economic growth, international trade, energy usage, emissions rates, carbon tax, emissions permit trading quantities and prices, induced technological change and behavioural change.

The model consisted of two parts, an economic sub-model and a climate sub-model. The economic sub-model was of the mutli-sectoral multi-regional general equilibrium type, based on two existing models, the GTAP-E (Burniaux and Truong, 2002) and the WIAGEM (Kemfert, 2002). The climate sub-model was a reduced form model, based on the existing ICLIPPS Climate Model (Tóth et al., 2003; Bruckner et al., 2003). The two sub-models were to be ‘soft linked’ to be used in simulations which could produce climate and technology-economic results which were consistent. The model was then used for climate policy studies, particularly for those relating to the European Union climate policies.
