<p>Aerosols of anthropogenic origin exhibit significant spatial variability, leading to localized environmental pollution and climate effects. The increasing international trade has caused extensive cross-border transfer of pollution, rendering the traditional production-based perspective insufficient for assessing the climate impacts of human activities in specific regions. In this paper, using the Earth System Model, five numerical simulation experiments are designed to simulate the impacts of anthropogenic sources of sulfate, associated with both production and consumption activities, on the climate of East and South Asia in different affluent regions. The results show that sulfate associated with consumption activities in developed countries has a greater impact on climate than production activities, whereas the opposite is observed for developing countries. This is because products produced in developing countries are largely consumed by developed countries.</p>
