3 Ways the Shipping Industry is Addressing Climate Change
The global shipping industry is on the verge of a transformation not seen since the transition from sail to steam.
In 2018, the industry emitted 1.1 billion metric tons of greenhouse gas emissions, representing 2.89% of all anthropogenic, or human-caused, emissions. And according to the International Maritime Organization (IMO) that could increase 90-130% in 2050, from a 2008 baseline.
This is the second and final part of The Shipping Industry: Plotting a Course for the Future, a two-part series from our sponsor Seaspan Corporation, that looks at three ways that containerships in particular, could evolve to become more sustainable.
1. Stemming the Tide of Containership Emissions
Unlike personal transport, which has a proven and commercially scalable technology in electric vehicles, there’s no silver bullet for shipping. However, existing technologies and design improvements could help make significant inroads against total fleet emissions.
According to data from Seaspan, propeller upgrades (6.5%), hull coatings (up to 5.0%), and main engine retrofits (4.4%) won’t bring emissions to zero on their own, but taken together they add up to big savings.
Technology | Annual Abatement potential |
---|---|
Speed reduction | 8.5% |
Propeller Upgrade | 6.5% |
Bulbous bow optimization | 6.4% |
Speed Controlled Pumps and Fans | 6.2% |
Hull coating | 5.0% (up to) |
Main engine retrofit | 4.4% |
Air lubrication | 3.5% |
Propeller boss cap fin | 2.5% |
Waste Heat Reduction | 2.2% |
Pre-swirl stator | 2.0% |
Weather Routing | 1.7% |
Autopilot Upgrade | 1.7% |
Vertical bow | 1.5% |
Wind shield | 0.6% |
High-Efficiency Lighting | 0.4% |
Interestingly, the biggest potential impact could come from slowing down ships (8.5%), which lowers fuel consumption and as a consequence, emissions. In the race to net zero, slow and steady could very well win the race.
2. Sailing the Ocean Green
In the long run, though, design tweaks don’t address the elephant seal in the room, which is the industry’s reliance on fossil fuels. Ships that run on alternate fuels, like ammonia, methanol, and even wind-power, are all in development, but many of the technologies are still in the early stages.
To help spur development, a group of countries at COP26, the annual UN climate conference, committed to establishing green shipping corridors where vessels would run on alternate fuels. A total of 24 countries signed the Clydebank Declaration, including the U.S. and the UK, and together they hope to catalyze the shift to zero emission shipping.
3. Leaving Fossil Fuels High and Dry
Many ship owners and operators are looking at Liquid Natural Gas (LNG) as a transitional fuel, while alternate fuel technologies mature. LNG emits between 13.2% and 16.6% less CO2 than conventional bunker fuel oil, a highly viscous residual fuel that is high in sulfur, so it’s no surprise that LNG-powered containerships represent 29.23% of the existing orderbook.
But with all but 2.4% of the current global fleet running on fossil fuels, there is still a long journey ahead.
On the Right Tack
The 1997 Kyoto Protocol established the IMO as the forum for climate change action for the shipping industry, which many have criticized for not moving fast and far enough on climate change.
At the July 2023 meeting of the Marine Environment Protection Committee, the IMO adopted a new greenhouse gas strategy, which set “indicative checkpoints” for emission reductions for 2030 and 2040 in place of binding targets, and committed to hit net zero “by or around, i.e. close to 2050, taking into account different national circumstances.” The IMO also declined to put a price on carbon.
Even without firm targets, many industry players aren’t waiting to move on the climate emergency. Seaspan, the world’s largest independent charter owner and manager of containerships, is moving to green their fleet. They recently signed an agreement to retrofit 15 ships with dual-fuel engines that can also run on green methanol, with an option for 45 more.
