Global Energy and Climate Model
Scenario analysis of future energy trends
This report is part of World Energy Outlook 2024
About this report
Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications, including the World Energy Outlook series and Energy Technology Perspectives series.
In 2021, the IEA adopted for the first time a new hybrid modelling approach relying on the strengths of both models. The integrated framework of the IEA’s Global Energy and Climate Model (GEC Model) is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA publications, including the World Energy Outlook series and Energy Technology Perspectives series.
