Switching to cleaner fuels is considered the most effective method of air pollution control because it addresses the root cause of the problem: the generation of contaminants during combustion processes.12

Most air pollutants, including those from industrial facilities, power plants, and motor vehicles, originate from the burning of fuels. By transitioning to cleaner fuels and processes, the total volume of harmful emissions—such as carbon monoxide, sulfur dioxide, and particulates—is reduced at the source.12

This preventative approach is prioritized because it minimizes the need to rely solely on secondary technologies, such as catalytic converters or scrubbers, which are designed to trap or treat pollutants only after they have already been generated. By reducing emissions before they enter the atmosphere, society can more effectively protect human health and the environment from the adverse effects of smog and other toxic substances.12
