IMO 2020, the mandate that ships plying most international waters slash their sulfur emissions starting in January of last year, was only another step in the International Maritime Organization’s long-running effort to ratchet down the shipping industry’s environmental impact. The group’s next focus, as you might expect, is reducing shippers’ carbon footprint — while no specific rules have been set, the IMO in 2018 laid out the goal of cutting ships’ carbon dioxide emissions by 40% from their 2008 levels by 2030. One way to move toward that goal would be fueling more ships with LNG, which emits 20-25% less CO2 than very low sulfur fuel oil. But as we discuss in today’s blog, shippers could augment those emission reductions by moving from the LNG trade’s traditional point-to-point model to optimization through cargo swapping.
