The fate of the vast quantities of oil and gas lodged under the shale, mud and sandstone of American drilling fields will in large part determine whether the world retains a liveable climate. And the US, the world’s largest extractor of oil, is poised to unleash these fossil fuels in spectacular volumes.
Planned drilling projects across US land and waters will release 140bn metric tons of planet-heating gases if fully realised, an analysis shared with the Guardian has found.
The study, to be published in the Energy Policy journal this month, found emissions from these oil and gas “carbon bomb” projects were four times larger than all of the planet-heating gases expelled globally each year, placing the world on track for disastrous climate change.
The plans include conventional drilling and fracking spanning the deep waters of the Gulf of Mexico to the foothills of the Front Range in Colorado and the mountainous Appalachian region. But the heart is the Permian basin, a geological formation 250 miles wide that sits under the mostly flat terrain of west Texas and New Mexico.
One lobe of this formation, known as the Delaware basin, is predicted to emit 27.8bn metric tons of carbon during the lifetime of planned drilling, while another, known as the Midland basin, will potentially unleash 16.6bn tons of emissions.
