One of the firmest medium- and long-term options for improving air quality in ports, which in turn meets the new requirements for pollutant gases and particulate matter emissions, is to opt for a change in propulsion fuel. Liquefied natural gas (LNG) is the alternative for ships and heavy goods vehicles promoted by the European Union in its Alternative Fuel Strategy approved in late 2012.

At European level, the natural gas mobility option would make it possible to diversify energy sources and reduce dependence on oil and, at a local level, to improve the competitiveness of the transport sector and its associated industries.

The Port of Barcelona sees the gasification of mobility not only as a solution to improve air quality in its surrounding area but also an opportunity to position the port along the key routes that use LNG as a propulsion fuel thanks to its ability to supply the new fuel through its regasification plant.
