E3ME is a macro-econometric model designed to assess global policy challenges. It is widely used for policy assessment, forecasting and research purposes. It is used especially for the assessment of climate and energy policy. International trade is an important part of the analysis. It is designed to assess both national and global policy challenges and give increased certainty to decision makers.

FTT (Future Technology Transformations) is a cutting-edge model of technology diffusion that is applied to a range of different energy sectors. FTT is based on innovation theory and evolutionary dynamics.

Currently there are FTT models for the power sector, passenger vehicles, the steel sector and household heading. Each one is linked to the E3ME model with two-way linkages between the technology dynamics and wider economy.
