IMO 2020 sulphur regs13 Apr 2021 13:19
"The volcano is also emitting an assortment of gases. Most notable is the emission of sulphur dioxide which is being tracked by Earth observing satellites. Sulfur dioxide (SO2), a colorless, bad-smelling, toxic gas that is part of a larger group of chemicals referred to as sulfur oxides (SOx). These gases, especially SO2, are usually emitted by the burning of fossil fuels, but volcanoes are productive emitters of sulphur dioxide too.
Satellite imagery shows a very large volume of gas escaping the volcano into the atmosphere. When mixed with precipitation, acid can rain down, bringing with it its own hazards to living things and objects at the surface."

-----------------------------------------------
The ongoing eruption and emittance of SO2 highlights the inadequacies of IMO, they went after an easy target with Sulphur which lets face it is naturally emitted by our planet. The result is that the Frankenstein low Sulphur fuel creates a lot more CO2 by way of refining and processing to remove the Sulphur, the fuel still emitts high levels of NOX & PM's. IMO did this IMHO to be seen to be doing something about climate change but gave us a red herring. Perhaps in hindsight they might have gone after other emissions such as NOX and particulate matter and Carbon emissions in a slow and sustained manner instead of inadequate bungling which has left us in the current situation of having to absorb the low Sulphur fuel implications until and assuming they get there act together.
Meantime lets hope that Volcano shuts down soonest and give the folks in the Caribbean rest bite from the immediate suffering.
