President Barack Obama. Major oil companies are also under<br />

pressure from investors to prove they will be able to adapt to<br />

future regulations that aim to curtail global warming.<br />

“With the climate crisis upon us, companies can’t afford to<br />

ignore their contributions to climate change,” said Ben Ratner,<br />

senior director at the Environmental Defense Fund. “In<br />

at least one or two parts of (Exxon’s methane) framework,<br />

what they are recommending appeared to fall considerably<br />

short of what would be considered the best available<br />

operational practice and regulatory requirements.”<br />

Exxon’s model framework included establishing a leak<br />

detection and repair program to identify and fix gas leaks<br />

as soon as possible, with inspections for leaks happening at<br />

least once per year. Some major oil companies are conducting<br />

inspections monthly, using sensors mounted on drones,<br />

Ratner said.<br />

“The truth is it needs to be much more, and we need to<br />

be driving to a world of continuous, real-time monitoring<br />

and rapid mitigation of this highly potent greenhouse<br />

gas,” Ratner said. “Once-a-year inspection is not a serious<br />

proposal for regulatory requirements that are up to the<br />

magnitude of the challenge.”<br />

Exxon, which is based in Irving, Texas, said its framework<br />

is a starting point for discussions for policy makers, and<br />

that governments or private companies could choose to go<br />

above and beyond what’s presented in the model.<br />

The company also suggested that if an oil and gas operator<br />

had to vent natural gas, it would be better to burn it off,<br />

or “flare” it, instead of releasing methane directly into the<br />

atmosphere. It suggested improving the combustion efficiency<br />

of flares so that methane isn’t accidentally released<br />

as a result of incomplete combustion.<br />

But flaring releases carbon dioxide, and while that is less<br />

potent than methane, it lasts longer in the atmosphere.<br />
