Este trabajo toma el caso de Argentina en 2021 para mostrar los impactos atmosféricos y económicos de usar GNL (Gas Natural Licuado) en la propulsión de dragas en la segunda mayor operación mundial de dragado a realizarse en el Rio de la Plata. Del punto de vista de las emisiones, el GNL las reduciría un 23%, actuando principalmente sobre las que afectan a la salud de las poblaciones costeras. El uso de BioGNL las reduce un 99% (60,000 Tons/a), incluyendo el efecto planetario del CO2. El impacto económico se estima en un ahorro del 14% del costo total del dragado (665 Millones de dólares) a lo largo de los 15 años de concesión. El 48% de este ahorro se debe a una reducción de costo de combustible y el 52% son ahorros de costos externos por el menor gasto necesario en la Salud Pública
