Welcome

GEMINI-E3 web is a web application which simulates world climate policies and allows the user to evaluate their impacts at the world level on the climate (emissions and concentrations) and on the economy (GDP, household's surpluses impacts…) thanks to the GEMINI-E3 model. At each user request, GEMINI-E3 web extracts the policy information from a large database containing several hundreds of simulations of GEMINI-E3, then, it compares them with a reference case (also called Business-As-Usual) where no climate policy occurs.

Use GEMINI-E3 web to simulate the following world climate policy:

Asterisk_yellow  A world GHG tax »

Asterisk_yellow  Greenhouse gases emissions reductions »

About GEMINI-E3

GEMINI-E3 is a Computable General Equilibrium (CGE) model started in 1994 at the French Energy Atomic Agency under the supervision of Alain Bernard, part-time Economic Adviser and member of Conseil Général des Ponts et Chaussées. The model is presently developed and managed in collaboration between French Ministry of Equipment and the REME laboratory at the EPFL (Lausanne, Switzerland).

GEMINI-E3 has been specifically designed to assess world climate change policies, in particular the effects of the Kyoto Protocol, both at the microeconomic and the macroeconomic levels. It is a multi-country, multi-sector, dynamic model incorporating a highly detailed representation of indirect taxation. It has been thoroughly used since 1995 to analyze a wide range of questions linked to energy, environment and economic growth. GEMINI-E3 runs in annual steps from the base year 2001 to 2050. The present version of the model is the fifth one, much more detailed that the initial version, and capable of assessing European policies such as the recent directive on quotas.
