Marseille, home to ferries, container ships and cruise ships, has recently seen an increase in smog. The maritime industry is considered the main culprit of this problem.
The use of so-called “scrubbing” technology, which involves spraying water into the exhaust plumes to trap certain contaminants, is preferred by some shipowners. However, environmentalists have drawn attention to the fact that the water is frequently released into the ocean afterwards.
Meanwhile, some companies are developing electric and sailing ships, and others are testing cleaner liquefied natural gas (LNG) or methanol engines to combat air pollution.
Regulators and increasingly stringent industry standards are pressuring shipping companies to reduce their emissions of greenhouse gases and pollutants into the atmosphere, but environmental activists want faster action.
The Piano already complies with the new standards that will come into force in 2025 to limit the sulfur content of marine fuels in the Mediterranean to 0.1%, Reverchon said.
Nine million deaths are attributed to air pollution worldwide each year, according to Atmosud, Regional Air Quality Observatory in France. “Air pollution has an annual economic impact on France of around 100 billion euros (about 99 billion dollars), mainly in the form of increased health care costs.”
The UN warns
The United Nations (UN) issued a statement on Wednesday, on the eve of the International Day of Clean Air for Blue Skies, stressing the need for collective responsibility and action.
