[4] A 2011 study measured found SO2 emissions to be ~ 4×1017 molec cm−2 slant column density directly over the oil refinery, decreasing as the plume disperses and NO2 peaking at ~ 1×1016 molec cm−2.

[1] Because of the energy transition in the country, where Uruguay had over 94% clean energy and the government has plans for a transition for other industries like transport, Minister of Environment Adrián Peña projected closing the refinery by 2035 to meet the zero emission goal set out in Uruguay Long Term Climate Strategy.
