Emissions control refers to the methods and technologies used to reduce the release of harmful pollutants into the atmosphere. This is important for improving air quality and protecting public health. Common sources of emissions include vehicles, industrial processes, and power plants, which can release substances like carbon dioxide, nitrogen oxides, and particulate matter. Various strategies are employed for emissions control, such as using cleaner fuels, implementing stricter regulations, and adopting advanced technologies like catalytic converters and scrubbers. These measures help to minimize the environmental impact of human activities and contribute to efforts against climate change.
