CO2 neutral by 2050
Maritime shipping wants to tighten climate targets

Shipping is the backbone of world trade and at the same time pollutes the environment and the climate. In this area of tension, the maritime industry is sounding out solutions – and now wants to increase the pace.
The international shipping industry wants to tighten its climate targets significantly.
Instead of halving the emissions of the climate-damaging gas carbon dioxide by 2050, as previously targeted by the World Shipping Organization IMO, the industry is now striving to avoid emitting any additional net CO2 into the atmosphere by then.
“Our industry wants to be climate-neutral as early as 2050,” said the President of the Association of German Shipowners (VDR), Alfred Hartmann. The World Shipowners Association (ICS) submitted a corresponding proposal to the IMO in London, an organization of the UN, on the initiative of the German shipowners.
“Climate protection can no longer be postponed, as the latest report by the international climate council IPCC confirms,” said Hartmann. “We hope that all participants in the maritime transport chain, but also the states in particular, will provide us with comprehensive support in this major task.”
Signal for green drive technologies
The shipowners’ association hopes that this initiative will send a signal to energy suppliers, shipbuilders and engine manufacturers to invest more in “green” propulsion technologies and fuels. Optimizations in the construction and operation of ships were not enough. Rather, a “fuel revolution” is needed in terms of development and availability. “Basically, the problem is not the engine, but the fuel,” emphasized VDR President Hartmann.
The problem: unlike cars, container ships cannot cover long distances with battery power. A wide range of alternative drive concepts and fuels are being discussed in the maritime industries. In addition to hydrogen and ammonia, the focus is on so-called “e-fuels” – for example, methanol, the combustion of which releases CO2, but which is first bound in large quantities during its production, so that a neutral cycle is created. However, all alternatives have one thing in common: Nothing is ready for the market and available on a large scale for broad practical use. Therefore, a shipowner who orders a ship can currently only choose between a diesel engine or the also fossil liquefied petroleum gas (LNG).
Industry under pressure
According to the IMO, shipping, which transports around 90 percent of all goods worldwide, is responsible for more than 2 percent of all CO2 emissions. The industry is also under pressure because the EU wants to tighten the targets for reducing greenhouse gas emissions. According to the Commission’s “Fit for 55” package, these should fall by at least 55 percent by 2030 compared to 1990. By 2050, no more climate-damaging greenhouse gases should be emitted in the Union.
