Abstract
Systems and methods for controlling extraction of landfill gas from a landfill via a gas extraction system comprising a plurality of wells are provided herein. In some embodiments, the method comprises obtaining a concentration of a greenhouse gas measured a distance above a surface of a region comprising the plurality of wells; determining whether the measure of the concentration of the greenhouse gas is greater than a first threshold; and in response to determining that the measure of the concentration of the greenhouse gas is greater than the first threshold, increasing a flow rate of landfill gas being extracted from at least one well of the plurality of wells.
