Researchers suggest forcing fossil fuel producers to bury tons of CO2

Holding fossil fuel producers accountable for managing waste from their products is an idea backed by a group of researchers who proposed extending the principle of extended producer responsibility (EPR) to oil, gas and coal in a scientific paper.

Storing CO2 emitted by factories: why this solution for the future is not working

According to the researchers’ paper, published in the journal Environmental Research Letters, study co-author Myles Allen, a professor at the University of Oxford, “ response to the current climate crisis and what it teaches us about climate problems “. He explains: ” we will have to stop fossil fuels from causing global warming before the world stops using them, the only way to do that is to put one ton of CO2 underground for every ton produced by the continued use of fossil fuels. Thus, it is incumbent on fossil producers to ensure the elimination of CO2 emitted during the use of their products. carbon sequestration commitment “say the authors.

C02 will be captured at the source or captured from the air to be stored underground.

Thus, the commitment to reach 100% equivalent of CO2 emitted into the atmosphere by 2050, the target date for carbon neutrality, will be captured at the source of increased CO2 or returned to the atmosphere for underground storage. Airborne CO2 capture already exists, but on a very small scale due to a lack of adequate funding: the largest installation of this type in Iceland currently removes in just one year what humanity produces in a few seconds.

Direct the fossil sector’s earnings to solving the climate problem

According to the authors, the situation will change if the fossil fuel sector is forced to turn to it en masse, especially since the industry has grown significantly over the past year with rising prices. “ Right now we just need to discuss how to channel these huge sums of fossil fuel revenue into climate solutions. “, pleads Myles Allen. Hugh Helferty, co-author of the study and former oil giant ExxonMobil, believes that the industry ” can » Sequestering CO2. ” What it lacks is a financial model and motivation. We have to adjust “he went on.

In its latest benchmark report, the UN’s Panel on Climate Change (IPCC) also believes that regardless of how quickly it manages to reduce greenhouse gas emissions, the world will have to turn to CO2 capture and storage. There is urgency: in 2022, CO2 concentration in the atmosphere reached a new record. 417 parts per million (ppm) “in annual increments” about 2.1 ppm, the same as in recent years “, notes the European program on climate change Copernicus (C3S).

Zoom – The past eight years have been the hottest on record worldwide

The past eight years have been record warm globally, surpassing pre-industrial temperatures by more than one degree, according to the annual report of the European climate change program Copernicus (C3S) released on Tuesday. Globally, it ranks fifth last year, only to be defeated in recent years and marked once again by the course of extreme events that show the consequences of global warming. It’s 2022, despite the cooling effects of the La Nina weather phenomenon about 1.2 °C » Warmer than 1850-1900, influenced pre-industrial climate, C3S confirms. In Europe, the continent with the fastest observed warming, 2022 is set to be the “second hottest year ever”, but the summer months are a new record for the whole continent, beaten by a huge margin in the UK and made worse by an unusual lack of rainfall . Spain, France or Portugal. from The Middle East, Central Asia and large parts of China, New Zealand, North Africa and the Horn of Africa C3S also set a new annual record.

In addition to temperatures, the report notes, the planet has been hit by an avalanche of extreme events: historic floods in Pakistan after an exceptional spring heat wave, heat waves and mega-forest fires in Western Europe, and summer heat waves in the center and east. Devastating floods in China, Nigeria, drought in the Horn of Africa.
