Air Pollution in our ports

The quality of the air we breath in our major ports is worrying. More residents in the areas around our ports are aware of this and are demanding action: they are all worried by the astronomic increases in the incidence of respiratory illnesses.

Around 12 months ago Maltese eNGO Birdlife carried out an air quality measurement exercise with the support of German experts from the German eNGO Nature and Biodiversity Union (NABU). Air samples taken from the Grand Harbour area indicted the presence of a high level of microscopic particulate matter, which ends up in our lungs.

The Grand Harbour is a hub of shipping activity and also includes a cruise liner terminal which, during the last five years, has had an average annual call rate of over 300 cruise liners.

Cruise liners make use of a large amount of electricity.  In a report covered in the local media, the campaign group T & E (Transport and Environment) said that sulphur emissions from cruise liners visiting Malta in 2017 were around 148 times as much as those emitted from the entire car fleet on the islands. This conclusion was reached after analysing satellite data.

In an investigative report it carried out two years ago focused on the P & O cruise liner company, the UK Television Channel 4 concluded that a cruise liner carrying around two thousand passengers had a daily pollution equivalent to one million cars. Large ships run on heavy fuel oil, which contains 3.5% sulphur – 3,500 times what is permitted in road fuel. There may be a lack of agreement on the exact figures for emissions from the shipping industry, but no one contests that they are substantial.

The international community continuously deals with what happens on the high seas. We can, however, deal more appropriately with what goes on in our ports. Particulate emissions in our ports by the shipping industry has a direct bearing on the residential communities surrounding our ports, notably Grand Harbour and Marsaxlokk Bay.

There are two specific issues which need to be prioritised. The first is for the regulatory authorities to ensure that EU legislation on restricting fuel use to the low sulphur type is observed. The second concerns the need to focus on infrastructural improvements in our ports to facilitate supplying the shipping industry with shore-based electricity, as a result ensuring that the ships’ generators – and consequently the resulting emissions to air –  stops when the ship berthed.

Two studies have already been carried out in Malta on the implications of a shore-to-ship electricity supply for the shipping industry. The first, which was completed in 2014, was carried out by Transport Malta and the second, carried out on behalf of the Malta Freeport Terminals, was completed in 2018. Both studies came to the conclusion that if the shipping industry changed to shore-side electricity there would be a substantial improvement in air quality in our ports. The issue of feasibility, however, is substantially dependent on what our competitors decide!

Does it make sense to keep encouraging economic activity that harms our health? The answer to this question is a definite “no”. Our ports are a most precious natural resource that we should use to enhance the quality of life of our coastal communities.
