Make fossil fuel firms remove carbon from atmosphere – study

Could fossil fuel companies be forced to remove planet-heating carbon pollution from the atmosphere? Researchers argue in a new paper that would be a cheaper, fairer solution to the climate crisis.

They suggest, in the research published yesterday, that the principle of extended producer responsibility (EPR) – a policy tool often used to deal with waste – should be extended to the oil, gas and coal industries.

‘Cost effective’

The study said impelling fossil fuel firms to use technologies to suck carbon from the air and bury it back in the ground would be a cost-effective decarbonisation strategy.

“It would also mean that the principal beneficiary of high fossil fuel prices, the fossil fuel industry itself, plays its part in addressing the climate challenge,” said the paper published in the journal Environmental Research Letters.

Ukraine invasion shocked energy markets

The invasion of Ukraine by key oil and gas producer Russia has sent shockwaves through energy markets, resulting in prices surging and shining a spotlight on bumper fossil fuel industry profits.

The study’s authors, including scientists and experts in Britain and the Netherlands as well as a former ExxonMobil manager, said the paper was a response to the energy crisis and potential lessons for the challenge of getting to net zero emissions.

“We need to start a conversation on how we redirect this colossal amount of money that currently is simply injected into fossil fuel rents to addressing the climate problem,” co-author Myles Allen, a professor at Oxford University, said.

“We are going to have to stop fossil fuels from causing global warming before the world stops using fossil fuels.”

‘Geological net zero’

To do that, he said, requires “geological net zero” – for every ton of carbon dioxide emitted by a fossil fuel, one ton of the greenhouse gas would need to be sucked out of the atmosphere and permanently put back in the ground.

The authors propose that all extractors and importers of oil, gas and coal be required to dispose of an increasing proportion of the carbon dioxide generated by their activities and products – up to 100% by 2050.

This would require increasing use of technologies to extract carbon dioxide at the emission source or directly from the air and store it permanently in the ground.

While there are projects doing just this already, these are not at anything like the scale needed. The largest direct air capture facility in the world, run by Swiss-based Climeworks, removes in a year what humanity emits in a few seconds.

But the economics would change if the fossil fuel sector were forced to rely on technology, the authors argue.

Industry is “capable” of removing carbon dioxide.

Hugh Helferty, co-author of the study and a former employee of oil giant ExxonMobil, said the industry is “capable” of removing carbon dioxide.

“What it lacks today is the business case, the motivation for executing it,” he told reporters at a press briefing, calling for regulation, like the rules banning lead in petrol.

Hannah Chalmers, Reader in Sustainable Energy Systems at the University of Edinburgh who was not involved in the research, said that EPR would be a “game changer” in delivering affordable low-carbon energy.

2024 plans

US oil and gas major Occidental last year announced plans to build by 2024 what the company said would be a bigger direct air capture project in the US Permian basin in oil field in Texas, with a one-million-ton annual carbon dioxide removal capacity.

The Paris Agreement calls for capping global warming below 2ºC, and most countries have signed on for a more ambitious limit of 1.5ºC. To meet that challenge, UN climate experts said last year that even under the most aggressive carbon-cutting scenarios, several billion tons of carbon dioxide will need to be extracted each year from the atmosphere by 2050.
