International shipping is a large and growing source of greenhouse gas emissions. It is a sector that the EU is trying to clean up as part of its pledge to become the first climate-neutral continent by 2050.

In this episode of Ocean, Euronews explores what changes are being made in the industry to try and cut carbon dioxide emissions.

DRONE INSPECTIONS

From a monitoring site near the port of Hamburg, pilots send drones out to ships to collect emission samples from exhaust plumes. The real-time results are helping to determine the worst polluters.

Jon Knudsen, a chemical engineer, and also the CEO/CTO of Explicit, said:

"A drone is ideal for places like this, where you're very close to the shore. It's easy for it to get to the plume of the vessel and find the right spot to do the sampling. They can help give information about the kind of fuel the vessels are burning."

Researchers from the European project SCIPPER are comparing a range of innovative pollution-measuring techniques from drones and next-generation coastal sensors to space satellites.

They want to ensure that all instruments produce accurate and reliable results that inspectors can rely on to enforce full compliance with new regulations.

Leonidas Ntziachristos, a professor at Aristotle University of Thessaloníki, and the SCIPPER Project coordinator, said:

"Ideally, we should have several established techniques, and then install in all major ports in Europe, but also in the world, monitoring stations like those so that we can make sure that all ships operate on the fuel that they are supposed to operate, and that their engines are calibrated and operating at the emission level that they are supposed to do."

Stationary sensors have also been placed along some coastlines and on bridges to monitor vessel traffic around the clock and identify various kinds of pollutants coming from passing ships.

AIR QUALITY

Maritime transport emits around 940 million tonnes of CO2 annually and is responsible for about 2.5% of global greenhouse gas (GHG) emissions, according to the European Commission.

These emissions are projected to increase significantly if mitigation measures are not put in place swiftly. According to the 3rd IMO GHG study, shipping emissions could under a business-as-usual scenario increase between 50% and 250% by 2050, undermining the objectives of the Paris Agreement.

"It is absolutely technically possible to produce less greenhouse gas emissions, but also lesser air pollutants or water and noise but we are also working on solutions which are economically viable. I think that one of the examples which is getting a lot of attention is electrified ferries because they are transporting passengers. But we still have a long way to go before all types of vessels will be sailing without emissions," Jaap Gebraad, the executive director of Waterborne said.

VIKING GRACE

A vessel called Viking Grace, that goes between Toku and Stockholm, has been hailed the greenest and quietest ship in the Baltic.

It is the first passenger ship of its size that runs on completely sulphur-free liquefied natural gas, and compared to present-day fuels, nitrogen and particulate emissions are reduced by 85% and greenhouse gases by 15%. The green alternatives mean it meets all EU emission requirements that apply.

Moreover, the excess heat from the engines is used when the ship is in port and the liquified natural gas cooling is harnessed for air conditioning.

The ship also has a new type of rotor sail that was developed in Finland - it is another innovation that saves fuel and reduces emissions.

Norsepower, the Finnish company behind the rotor sails, has so far installed them on four vessels and is working on two more. It says the technology is in high demand and can make a difference on a global scale.

"Our ambition is to fit up to 30 thousand ships in the world with this technology, and according to independently verified reports it looks like we can reduce the total emissions of global shipping by nearly 10% by just employing this one single technology," Tuomas Riski, CEO and partner of Norsepower said.
