Integrated Assessment is a systematic approach that combines knowledge from various disciplines to evaluate complex issues, particularly in areas like environmental policy and climate change. It involves the integration of scientific data, economic analysis, and social considerations to inform decision-making processes. This method often utilizes models to simulate the interactions between different systems, such as the economy and the environment. By doing so, Integrated Assessment helps policymakers understand the potential impacts of their choices, guiding them toward sustainable solutions that balance ecological health with economic growth, as seen in frameworks like the Intergovernmental Panel on Climate Change (IPCC) assessments.
