New study reveals
A new study, published in the journalAtmospheric Chemistry and Physics by researchers at IIASA and in Norway, Finland, and Russia, finds that gas flaring from oil extraction in the Arctic accounts for 42% of the black carbon concentrations in the Arctic, with even higher levels during certain times of the year.

In the month of March for example, the study showed that flaring accounts for more than half of black carbon concentrations near the surface. Globally, in contrast, gas flaring accounts for only 3% of black carbon emissions.
The researchers also found that residential combustion emissions play a greater role in blackcarbon pollution than previously estimated, after they incorporated seasonal differences in emissions into the model.
