Gas emission control refers to the methods and technologies used to reduce the release of harmful gases into the atmosphere. These gases, such as carbon dioxide (CO2), methane (CH4), and nitrogen oxides (NOx), contribute to air pollution and climate change. Effective control measures can include using cleaner fuels, improving energy efficiency, and implementing regulations that limit emissions from industries and vehicles. Various technologies are employed in gas emission control, including catalytic converters in cars, scrubbers in power plants, and carbon capture and storage (CCS) systems. These solutions aim to minimize the environmental impact of human activities while promoting cleaner air and a healthier planet.
