Emission monitoring is the process of measuring and analyzing pollutants released into the air, water, or soil from various sources, such as factories, vehicles, and power plants. This practice helps ensure compliance with environmental regulations and identifies areas where emissions can be reduced to protect public health and the environment. Technologies used in emission monitoring include sensors, analyzers, and remote sensing devices. These tools collect data on the concentration of harmful substances, such as carbon dioxide and nitrogen oxides, allowing organizations to track their environmental impact and implement strategies for improvement.
