MESSAGE Model (Model for Energy Supply Strategy Alternatives and their General Environmental Impact)

The MESSAGE Model is a tool used to evaluate different energy supply options and their overall environmental impacts. It helps policymakers and planners compare various energy strategies—like using coal, natural gas, renewables, or nuclear power—by analyzing their costs, emissions, and sustainability. The model considers technological, economic, and environmental factors to identify the most effective and environmentally responsible way to meet future energy demands. In essence, it supports decision-making by providing a clear picture of how different energy choices affect the environment and society over time.
