Manufacturing and Trade Model

The IEA’s Manufacturing and Trade (MaT) Model was first developed for the 2024 edition of Energy Technology Perspectives (ETP) to produce scenario projections of manufacturing and trade across six key energy technology supply chains. These cover solar photovoltaics (PV), wind turbines, electric cars, batteries, electrolysers and heat pumps. This model is now used to generate detailed sector-by-sector and region-by-region long-term scenarios in IEA publications such as the World Energy Outlook and Global EV Outlook.

The MaT model is part of the IEA’s broader modelling framework and is closely linked to the Global Energy and Climate Model (GEC), as it draws on the same modelling scenarios, each of which is built on a different set of underlying assumptions about how the energy system might evolve over time.
