The volumes of flared and vented gas in Upstream are calculated following legal/ internal regulations and are based on gas balance. Regular checks are performed and calculated volumes calibrated, if needed. Data may change based on such regular checks outcome and consolidated annually. Further to the above internal process, in 2020 in one location having two alternative stacks (one for flaring, one for venting), a quantity of gas was reclassified from flaring to venting.
