Brokers and scientists angry at unintended consequence of key shipping emissions law

Home | Press | Brokers and scientists angry at unintended consequence of key shipping emissions law

IMO 2020 rules on sulphur emissions are having an unintended consequence in the world’s oceans.

UK shipbroker Alibra Shipping said global emissions of sulphur dioxide (SO2) from shipping have fallen by around 10% since 2020.

“But could this actually be contributing to global warning, the opposite to the intended outcome?” Alibra Shipping asked.

IMO 2020 rules on sulphur emissions are having an unintended consequence in the world’s oceans

The International Maritime Organisation’s 2020 limits on sulphur content in ship fuel have been a big positive in lowering vessel emissions.

But scientists and brokers are now arguing that the rules have had an unintended consequence of warming the global ocean surface temperature — and that could provide an opportunity to develop solar geo-engineering.

UK shipbroker Alibra Shipping said global emissions of sulphur dioxide (SO2) from shipping have fallen by around 10% since 2020.

“But could this actually be contributing to global warning, the opposite to the intended outcome?” Alibra Shipping asked.

Alibra explained: “Although it sounds like the stuff of science fiction, the sulphur particles would be artificially introduced into the atmosphere using planes for stratospheric dispersal at altitude of 20 km, which is far higher than a commercial jet usually flies.”
