CO2 captured as part of the partnership would provide Occidental with "CO2 at a lower cost than our organic CO2 that we use today," said Vicki Hollub, the company's chief executive officer.

"For most of that time period the growth rate in CO2 has been increasing because we've been increasing the CO2 we release into the atmosphere," Keenan told Motherboard.
