 The VIARS satellite system is capable of accurately identifying and measuring the radiant emissions from gas flares at night. This allows for the estimation of the total flared gas volume, which is approximately 143 BCM or 3.5% of global production. The majority of this gas is produced in upstream production areas, with only 8% occurring at refineries and 2% at LNG terminals. This article was authored by Christopher D.
