Critical review finds actual measurement data on segments of natural gas lifecycle sparse or lacking

Green Car Congress

After a critical review of the literature on the air impacts of increased natural gas acquisition, processing, and use, a team of US researchers has determined that that actual measurement data on various individual segments of the natural gas life cycle are sparse or critically lacking. well production end-of-life.
