The E3 (“economy-energy-emission”) models are macro-econometric (dynamic) input-output models that take into account induced income and price effects as well as temporal aspects of policy measures and the adjustment reactions of affected actors. They depict the economy, energy and environment in an integrated manner and primarily use national data sources. Both emission reduction and climate impact adaptation scenarios can be evaluated in terms of their effects on economic and environmental indicators. The e3 models are created in MS Excel, particularly as part of capacity building, and can be used by project partners in the respective countries. In recent years, the GWS has developed corresponding E3 models for Egypt, Algeria, Georgia, Kazakhstan, Mongolia, Tunisia and Uganda, e.g. e3.ug, whereby the ISO country code is appended to the model’s name. A Model for Morocco is under development. Based on the GWS standard model software, comparable models have also been developed and used for Russia (e3.ru) and Saudi Arabia (e3.sa) and the much more complex e3.at for Austria. The creation of the E3 models is based on a wide range of experience in the development and application of the PANTA RHEI and GINFORS-E models.
