Poisonous air pollution from cruise ships round ports are larger than pre-pandemic ranges, leaving Europe’s port cities choking in air air pollution, a brand new Transport & Setting research exhibits. Regardless of the introduction of the UN delivery physique’s sulphur cap in 2020, final yr Europe’s 218 cruise ships emitted as a lot sulphur oxides (SOx) as 1 billion automobiles. Nevertheless, on the port of Venice air pollution from cruise ships fell 80% following the town’s ban on massive cruise ships. It exhibits that it’s attainable to sort out air air pollution, says T&E, which requires larger electrification at ports with a view to save lives.

Constance Dijkstra, delivery campaigner at T&E, mentioned: “The pandemic offered some respite for port cities, however that is now effectively and actually over. Cruising is again and vacationer hotspots like Barcelona and Athens are once more choking on poisonous air air pollution from cruise ships. Venice has proven that tackling cruise ship air pollution is feasible, however bans aren’t the one manner. Ports can considerably cut back air pollution ranges by forcing ships to plug into electrical energy on the port as a substitute of working their engines, and by supporting the adoption of zero-emission fuels.”

In comparison with 2019, the variety of cruise ships, the time they spent round ports, and the gasoline they consumed all elevated by round 1 / 4 (23% to 24%). This resulted in a rise of 9% in SOx emissions, 18% in NOx emissions, and 25% in PM2.5 emissions — three poisonous air pollution.

Barcelona was Europe’s most polluted port final yr adopted by Civitavecchia, a coastal port northwest of Rome and the Athenian port of Piraeus. In Barcelona, cruise ships emitted nearly 3 times extra SOx than all of the automobiles within the metropolis. SOx limits for automobiles in Europe are 100 instances extra stringent than these for ships¹.

Venice, alternatively, improved considerably. Probably the most cruise polluted port in 2019 dropped to forty first final yr following a ban on massive cruise ships getting into the port that was launched in 2021, resulting in an 80% fall in SOx emissions.

That didn’t nevertheless cease Italy from surpassing Spain as essentially the most cruise ship polluted nation in Europe. Though the Mediterranean bears the brunt of cruise ship air pollution, Norway got here fourth within the rating and even had the very best cruise visitors of any nation, albeit with smaller ships.

Probably the most polluting cruise ships operator was MSC Cruises — whose cruise ships emitted practically as a lot SOx as all of the passenger automobiles in Europe. Accounting for all of its subsidiaries, the Carnival group polluted essentially the most.

Many cruise operators like MSC are investing in fossil fuel (LNG) as a cleaner various. Thus far this yr, greater than 40% of cruise ships ordered had been LNG-powered. These ships are higher when it comes to air air pollution, however they’re extraordinarily damaging from a local weather perspective because of methane leaks from their engines – a potent fuel over 80 instances extra warming than CO2². P&O’s MS Iona, for instance, emitted as a lot methane as 10,500 cows over a yr.

Constance Dijkstra, concluded: “Switching from oil to fuel is like buying and selling smoking for alcohol. It could assist the cruise ship trade to cut back air air pollution however it’s horrible from a local weather perspective.”

¹ The most effective marine sulphur commonplace (0.1% Sulphur (S) | 1000 ppm) stays 100 instances worse than Europe’s sulphur commonplace for street diesel and petrol (0.001% S | 10 ppm) in place for the previous 15 years.

² Methane’s (CH4) international warming potential (GWP) is 82.5 instances larger than CO2 over a interval of 20 years and 29.8 instances larger over a 100-year interval.
