The researchers developed a model called BelMod to analyze how different policies in Belgium affect the environment, energy, and finances. This model helps decision-makers understand the costs and benefits of their choices and see who might be impacted. By looking at different regions and types of households, BelMod can show how things like a carbon tax can affect different parts of the economy. Belgium has committed to reducing greenhouse gas emissions, and BelMod helps figure out the best ways to do that. The model uses a detailed database to track production, spending, and more. The researchers used BelMod to study two scenarios and show how it can help make informed decisions.
