Exxon promises to cut emissions that hasten climate changeELIZABETH CONLEY/AP Exxon says it has spent more than US$9 billion (NZ$13 billion) on lowering emissions since 2000. Methane is a much more potent greenhouse gas than carbon dioxide, although methane does not last in the atmosphere as long. Increasingly, Exxon and other major oil and gas companies have been under fire for their emissions. "We have a longstanding commitment to improve efficiency and mitigate greenhouse gas emissions," said CEO and chairman Darren W Woods on Wednesday. Exxon was also one of eight major oil and gas companies that announced a collective commitment to reducing methane emissions.
