Emissions research focuses on studying the release of pollutants, greenhouse gases, and other harmful substances into the atmosphere. This research area aims to understand the sources, impacts, and mitigation strategies for emissions from various sources such as vehicles, industry, agriculture, and energy production. Researchers in this field often use modeling, monitoring, and experimental techniques to quantify and analyze emissions and their effects on air quality, climate change, and human health. The ultimate goal of emissions research is to develop sustainable solutions to reduce emissions and improve environmental quality.
