What is soot tags?

Soot tags are microscopic particles of black carbon emitted by diesel engines, coal-fired power plants, and other sources of combustion. They can contribute to air pollution and health problems, as well as climate change by absorbing sunlight and warming the atmosphere. Soot tags are easy to trace back to their source using chemical analysis, making them a useful tool for tracking emissions and developing strategies for reducing pollution. They can also help enforce regulations and hold polluters accountable.
