Global Change Assessment Model (GCAM)

The Global Change Assessment Model (GCAM) is a computer-based tool that helps researchers and policymakers understand how different factors—like energy use, climate policies, technological advancements, and economic growth—affect the Earth's future environment and economy. It simulates how these elements interact over time, predicting outcomes such as greenhouse gas emissions, energy consumption, and climate impacts under various scenarios. By doing so, GCAM supports informed decision-making aimed at managing climate change, promoting sustainable development, and balancing human needs with environmental health.
