Flare gas is the name given to the surplus waste gas produced during the extraction of crude oil and the subsequent refining process. It is typically vented to atmosphere and burned in a flare stack. The process inevitably releases large quantities of carbon dioxide (C02) to the atmosphere, which is a major contributor to global warming.
