Sulfur dioxide is not a direct greenhouse gas. It may even have a temporary heating effect, as the suspension suspended in the solar suspension may not have reached the surface. But it has, on the other hand, serious consequences for the environment, in the form of acid rain, and for human health, by causing or worsening cardiorespiratory problems.
Impacts, associated with an increase in the number of cruise ships, important sources of sulfur dioxide, have led the European Union to sulfur in the first steps of ships, since 1999. After several progressive reductions, these the European Parliament , 5% a%, capped at 0 – times what was allowed by naval, 3.5%
Portugal has now passed this reduction into national legislation. At the initiative of the Ministry of the Sea, through the Directorate-General for Natural Resources, Safety and Maritime Services (DGRM), Decree-Law nº 106/2021 was published in December, which establishes the implementation, verification and verification of the new maximum principles of non-combustible sulfur marine services. In the case of ports and anchorages, the limit is even lower – 0.1% – for vessels moored for more than two hours.
Fines can go up to €44,850, and in the most serious cases, the vessel may be seized. Inspection is the responsibility of ENSE (National Entity for the Energy Sector) and DGRM.
According to a 2017 study by the European Transport and Environment Federation, Lisbon is the sixth most polluted in Europe by sulfur dioxide emanating from cruise ships. It is estimated that these metropolises emit 5100 tons of this gas annually in the Portuguese capital, which is equivalent to 86 times the amount of sulfur dioxide throughout the national territory.
