Why decarbonizing marine transportation might not be smooth sailing

The International Maritime Organization (IMO) has recently announced that it will reduce greenhouse gas emissions of the shipping sector in half by 2050. As one of the world’s biggest contributors to emissions, there is an urgent need for a drastic change in this sector to make it more sustainable. However, experts are not so convinced that the IMO’s target will be achievable.

An urgent need to reduce shipping emissions

Around 3% of global emissions are accounted for by shipping, representing 10% of transport emissions, equating to roughly the same level emissions associated with the aviation industry. Therefore, cutting emissions in this sector is vital to prevent further damages to the environment. However, since 90% of the world’s physical trade moves via shipping methods, decarbonizing the industry will not be easy. We must start making significant changes now because if we don’t, by 2050, shipping emissions are expected to rise between 50% and 250%.

Demand for shipping increases

One potential method is to reduce the volume of shipments made each year. However, this may be a challenge due to the efficiency and advantages of shipping emissions over alternative transportation methods such as truck, rail, or air.

Slow-steaming

Another route to cutting shipping emissions is slow-steaming. This method allows ships to move slower, reducing fuel consumption. While it is effective short-term, experts do not believe that it offers a long-term solution to permanently bring down shipping emissions because of the high operating and employment costs associated with it.

Alternative fuels may provide the answer

Currently, the majority of the world’s shipping fleet runs on diesel, with just 1% using alternative fuels. Fortunately, recent advances in renewable technology have introduced several alternative low-carbon fuels into the market, such as biofuels, batteries, liquified natural gas, wind, and hydrogen fuel cell systems with zero emissions. Scientists are also working on developing a solar-powered ship, bringing us a step closer to a cleaner environment. Alternative fuels may provide the long-term solution necessary to bring down shipping emissions and secure the future of the shipping industry, allowing businesses across the globe to continue to enjoy the benefits of marine freight.
