As far as I remember, that was tried with ships and it has some collateral effects that cause different damages to the oceans.
I think I recall the opposite. After having somewhat cleaner fuel, the ships cleaner exhaust caused more warming as the sulfur in the fuel was having a side effect of mitigating warming somewhat. It was raised as a point of maybe we should consider the approach of we are in dire straights.
I remember to have read that change caused some other problems, and these collateral problems were unexpected.
But I don't remember if the problem were about the ocean currents or that the ocean was warmer or a mix of the two plus something else.
How is that relevant to ships? It's released to high in the atmosphere.
My point was that this already tested on a smaller scale with ships: the fuel changed and that changed the exhaust fumes ability to reflect sunlight which cause some problems the proponents of the solution have not foresee.
