Emission research focuses on the study of pollutants and greenhouse gases that are released into the atmosphere by various sources, such as vehicles, industries, and natural processes. This research area aims to understand the sources, causes, and effects of emissions on air quality, climate change, and human health. Researchers in this field collect data on emission levels, develop models to predict future emissions, and propose strategies to reduce emissions and mitigate their negative impacts on the environment. Studies in this area often involve interdisciplinary approaches, including chemistry, physics, engineering, and environmental science.
