Gas flaring is the controlled burning of natural gas, used as a means to burning off flammable gas during drilling, production or processing. As pure natural gas is mostly methane, a greenhouse gas, there are concerns about the volatile organic compounds released from oil and gas operations that are known to exacerbate asthma and other respiratory problems. Environmental Defense Fund's (EDF) Oil and Gas Program leads the organization’s efforts to bolster environmental protections from the impact of oil and gas development. EDF seeks to collaborate on furthering policy and technology solutions to flaring. EDF has found that while many companies are flaring excessive amounts of natural gas, the data suggest that companies have the potential to reduce wasted energy and pollution.
