A maritime sulfur dioxide emissions switch monitoring system has an emissions sampling apparatus that is self-powered and requires a low power for operation. The emissions sampling apparatus has sensitive and selective chemical sensing technology capable of quantification of sulfur dioxide and carbon dioxide. Relative humidity, temperature and pressure sensors, in addition to sulfur dioxide and carbon dioxide are used for monitoring the exhaust gas. Filters are used to eliminate solid and liquid aerosolized components in marine engine exhaust.
