WITCH (World Induced Technical Change Hybrid model)

WITCH (World Induced Technical Change Hybrid model) is an advanced economic tool used to analyze how technological progress, driven globally or regionally, impacts energy use, emissions, and climate change. It combines economic growth patterns with technological innovations, considering how policies and investments influence the development of cleaner or more efficient technologies. By capturing interactions between economy, technology, and environment, WITCH helps policymakers understand potential future scenarios and the effectiveness of climate policies, supporting informed decisions to achieve sustainable and low-carbon growth pathways worldwide.
